Continental concerted efforts to control the seventh outbreak of Ebola Virus disease in Uganda: The first 90 days of the response.

On 20th September 2022, Uganda declared the 7th outbreak of Ebola virus disease (EVD) caused by the Sudan Ebola strain following the confirmation of a case admitted at Mubende Regional Referral Hospital. Upon confirmation, the Government of Uganda immediately activated the national incident management system to initiate response activities. Additionally, a multi-country emergency stakeholder meeting was held in Kampala; convening Ministers of Health from neighbouring Member States to undertake cross-border preparedness and response actions. The outbreak spanned 69 days and recorded 164 cases (142 confirmed, 22 probable), 87 recoveries and 77 deaths (case fatality ratio of 47%). Nine out of 136 districts were affected with transmission taking place in 5 districts but spilling over in 4 districts without secondary transmission. As part of the response, the Government galvanised robust community mobilisation and initiated assessment of medical counter measures including therapeutics, new diagnostics and vaccines. This paper highlights the response actions that contributed to the containment of this outbreak in addition to the challenges faced with a special focus on key recommendations for better control of future outbreaks.

Assessing the impact of regional laboratory networks in East and West Africa on national health security capacities.

National laboratories are a fundamental capacity for public health, contributing to disease surveillance and outbreak response. The establishment of regional laboratory networks has been posited as a means of improving health security across multiple countries. Our study objective was to assess whether membership in regional laboratory networks in Africa has an effect on national health security capacities and outbreak response. We conducted a literature review to select regional laboratory networks in the Eastern and Western African regions. We examined data from the World Health Organization Joint External Evaluation (JEE) mission reports, the 2018 WHO States Parties Annual Report (SPAR), and the 2019 Global Health Security Index (GHS). We compared the average scores of countries that are members of a regional laboratory network to those that are not. We also assessed country-level diagnostic and testing indicators during the COVID-19 pandemic. We found no significant differences in any of the selected health security metrics for member versus non-member countries of the either the East Africa Public Health Laboratory Networking Project (EAPHLNP) in the Eastern Africa region, nor for the West African Network of Clinical Laboratories (RESAOLAB) in the Western Africa region. No statistically significant differences were observed in COVID-19 testing rates in either region. Small sample sizes and the inherent heterogeneities in governance, health, and other factors between countries within and between regions limited all analyses. These results suggest potential benefit in setting baseline capacity for network inclusion and developing regional metrics for measuring network impact, but also beyond national health security capacities, other effects that may be required to justify continued support for regional laboratory networks.

Implementation of the COVID-19 laboratory testing certification program (CoLTeP), Zimbabwe, 2021.

The Africa Union (AU) Trusted Travel Initiative was introduced in 2021 to support Africa Union member states enhance their current health screening systems. Trusted Travel offers an online digital platform for the verification and authentication of COVID-19 results based on a collaborative effort across a network of participating COVID-19 testing laboratories. In this paper, we describe the certification process of laboratories to qualify for listing on the AU Trusted Travel platform as approved and recognized COVID-19 testing facilities. A checklist prepared from the ISO15189: 2012, ISO15190: 2020 and World Health Organization Laboratory Safety Manual, 4th edition was used to audit laboratories. Approved auditors completed the audit checklist through reviewing laboratory documents and records, observing laboratory operations whilst asking open-ended questions to clarify documentation seen and observations made. A laboratory was recommended for certification after scoring at least 90%. Between May and September 2021, a total of 26 (19%) of the 134 medical laboratories authorized for SARS-CoV-2 testing had been audited for CoLTeP certification in Zimbabwe. The majority 16 (62%) attained 5 stars rating with 10 (38%) attaining 0-4 stars. Performance was highest in the area of test result and data management (mean score 93%, SD 9.1). The least performance of the laboratories was on the laboratory biosafety and biosecurity (mean score 73%, SD 17.0) and Quality Control and Assurance (mean score 71%, SD 15.0). There is need for laboratories to commit their resources to quality assurance programs and training of laboratory personnel in biosafety and biosecurity as part of continuous quality improvement.

Implementation of COVID-19 Laboratory Testing Certification Program (CoLTeP) in African Region.

Objectives: Coronavirus disease 2019 was declared a global pandemic in March 2020 with correct and early detection of cases using laboratory testing central to the response. Hence, the establishment of quality management systems and monitoring their implementation are critical. This study describes the experience of implementing the COVID-19 Laboratory Testing and Certification Program (CoLTeP) in Africa. Methods: Private and public laboratories conducting SARS-CoV-2 testing using polymerase chain reaction were enrolled and assessed for quality and safety using the CoLTeP checklists. Results: A total of 84 laboratories from 7 countries were assessed between April 2021 to December 2021 with 52% of these from the private sector. Among them, 64% attained 5 stars and were certified. Section 4 had the highest average score of 92% and the lowest of 78% in Section 3. Also, 82% of non-conformities (NCs) were related to sample collection, transportation, and risk assessments. Non-availability, inconsistency in performing, recording, instituting corrective actions for failed internal and external quality controls were among major NCs reported. Conclusions: Laboratories identified for SARS-CoV-2 testing by public and private institutions mostly met the requirements for quality and safe testing as measured by the CoLTeP checklist.

Comparison of Real-Q 2019-nCoV and DaAn Gene 2019-nCoV polymerase chain reaction assays for the detection of SARS-CoV-2.

BACKGROUND: Various nucleic acid amplification assays for the diagnosis of SARS-CoV-2 infection have been developed, and there is a need to assess their test performance relative to one another. The aim of this study was to compare the performance characteristics of the Biosewoom Real-Q 2019-nCoV assay targeting the E and RdRP genes to DaAn Gene 2019-nCoV kit targeting the N gene and ORF1ab in the diagnosis of SARS-CoV-2. METHODS: We performed a diagnostic comparison study by testing nasopharyngeal samples for SARS-CoV-2 using the two reverse transcription polymerase chain reaction (RT-PCR) assays. Assay agreement was assessed by overall percent agreement, negative percent agreement, positive percent agreement, and Cohen's kappa coefficient. RESULTS: A total of 48 nasopharyngeal samples were tested using the two assays. One sample was invalid, and three showed inconclusive results with Real-Q; hence, 44 were included for the comparative analysis. Overall, percent agreement between the assays was 93.2% (95% CI 81.3%-98.6%), Positive percent agreement (PPA) was 86.4% (95% CI 65.1%-97.1%) and negative percent agreement (NPA) was 100% (95% CI 84.6%-100%). The kappa coefficient was 0.86 (95% CI 0.72-1.01). Three samples (6.8%) were positive with DaAn gene kit and negative with Real-Q. The fluorescence intensity for Real-Q reporter dyes was low. CONCLUSION: The two kits showed high levels of concordance in their detection of SARS-CoV-2 despite having different gene targets. The Biosewoom kit can be improved through addressing the fluorescence intensity of the target dyes, and feedback was given to the manufacturer.

An analysis of the COVID-19 laboratory dataset at AiBST Laboratory in Harare, Zimbabwe, 2020.

INTRODUCTION: coronavirus disease 2019 (COVID-19) has become a major public health problem and has spread rapidly around the globe since its first identification in Wuhan, China, in December 2019. Zimbabwe reported its first case on the 20th March 2020, and since then the disease has spread to almost every part of the country. Laboratory testing is important in controlling this pandemic. However, few studies have focused on assessing trends of SARS-CoV-2 laboratory data. We described SARS-CoV-2 data from African Institute of Biomedical Science and Technology (AiBST) Laboratory in Harare, Zimbabwe. METHODS: a retrospective record review of secondary SARS-CoV-2 data from AiBST Laboratory in Harare between May to September 2020 was done. Epi Info TM 7.2.2.6 was used to generate frequencies, proportions and conduct bivariate analysis. RESULTS: a total of 6,535 SARS-CoV-2 laboratory records were analysed. The median age of the patients was 36 years and 55% (3594/6535) were males. There was an increase in average analytical turn-around time (TAT) of SARS-CoV-2 results from May to August 2020. Analytical and preanalytical TAT remained above 2 days from August to September. Males were 1.18 times at risk of being SARS-CoV-2 infected than females (p<0.05). The risk of being SARS-CoV-2 infected increased with age from 1.06 in the 11-20 age group to 1.45 in the 41-50 age group. CONCLUSION: COVID-19 poses a greater threat to the older age groups and to men. The delayed TAT of SARS-CoV-2 results limits the efforts to control the pandemic. Decentralization of testing to provincial and district level would help improve result TAT.

Trends in antimicrobial resistance of bacterial pathogens in Harare, Zimbabwe, 2012-2017: a secondary dataset analysis.

BACKGROUND: Antimicrobial resistance is one of the most serious public health threats of the twenty-first century. The implementation of AMR surveillance in Zimbabwe is limited. However, data from a private laboratory in Harare revealed increasing resistance rates to common antibiotics like ampicillin (i.e., from 73.9% in 2011 to 74.6% in 2015). The increasing resistance rates indicate that Zimbabwe is affected by AMR. This study was done to determine the magnitude of AMR in Harare and determine the trends of AMR to first-line and to last-resort antibiotics and make recommendations to mitigate the problem. METHODS: A retrospective record review of data collected from the microbiology department at a private laboratory between January 2012 and December 2017 was done. The outcome of interest was the antibiotic susceptibility of bacterial isolates. Microsoft Excel 2016 was used to plot trends from 2012 to 2017 and Epi Info™7 was used for statistical analysis. RESULTS: A total of 23,432 isolates, of 12 medically important bacteria were analysed. Forty-three percent of the isolates were from urines, 36.7% were from pus swabs and 7% were from blood. The most common pathogen was Escherichia coli (43.2%), followed by Staphylococcus aureus (15.8%) and the least common was Neisseria gonorrhoea (0.2%). Resistance was highest to ampicillin followed by penicillin, both ranging between 70 and 100% over the six years. Statistically significant increases in resistance to commonly used antibiotics were observed in amoxicillin-resistant E. coli and Streptococcus pneumonia and third generation cephalosporin-resistant E. coli. There was an increase in resistance to last-line antibiotics i.e., fluoroquinolone-resistant Salmonella spp. and carbapenem-resistant Pseudomonas aeruginosa and Acinetobacter baumannii. However, methicillin-resistant S. aureus showed a decreasing trend. CONCLUSIONS: There is a high burden of drug resistance to common antibiotics in Harare and an emergence of resistance to last-line antibiotics.

Food borne illness amongst health care workers, at a Central Hospital, Harare, Zimbabwe, 2016: a retrospective cohort study.

OBJECTIVES: Health care workers (HCW) at a Central Hospital, were served lunch at the hospital canteen on 12 December 2016. On 12 December 2016 at 1700 h, there was a sudden onset of symptoms suggestive of gastrointestinal illness among HCW. We conducted a retrospective cohort study to determine the cause and the factors associated with illness among the HCW at the hospital. RESULTS: We interviewed 96 respondents. The median incubation period was 6 h (Q1 = 4; Q3 = 12). Abdominal pain (97.5%) and watery diarrhoea (95%) were the most common symptoms. The majority (97.5%) took antibiotics before collection of stool specimen for analysis, with 24 (60%) of 40 HCW treating themselves. Eating chicken (RR = 44.2, CI 74.07; 95.34) during lunch was associated with the illness. Staphylococcus aureus and Escherichia coli were isolated from food handlers' hands, kitchen utensils and work surfaces. Staphylococcus aureus was isolated from chicken. None of food handlers had valid medical certificates. One out of four food handlers was formally trained.

Evaluation of the maternal mortality surveillance system in Mutare district, Zimbabwe, 2014-2015: a cross sectional study.

INTRODUCTION: In Zimbabwe the integrated disease surveillance and response guidelines include maternal mortality as a notifiable event reported through the Maternal Mortality Surveillance System (MMSS). A preliminary review of the MMSS data for Mutare district for the period January to June 2014 revealed that there were some discrepancies in cases notified and those captured on the T5 monthly return form. There were also delays in reporting of some maternal deaths. Poor reporting indicated shortcomings in the MMSS in Mutare district and we therefore sought to assess the performance of the maternal mortality surveillance system in Mutare district. METHODS: A descriptive cross sectional study was conducted using Centers for Disease Control and Prevention updated guidelines for evaluating public health surveillance systems. A total of 64 health workers were enrolled into the study from 19 selected health facilities in Mutare district and 32 maternal death notification forms submitted in 2014 to the provincial office were reviewed to assess the quality of information on the forms. Interviewer administered questionnaires were used to collect information from enrolled health workers, the system's attributes namely usefulness, acceptability, simplicity, stability, data quality, timeliness and completeness were assessed and a checklist was used to assess availability of resources for the implementation of the maternal mortality surveillance. We also determined the cost of reporting each maternal death in Mutare district. RESULTS: Half of the study participants gave the correct definition of a maternal death. All health workers participated and were willing to continue participating in the maternal mortality surveillance. Majority of health workers, 79.7% used data generated from the surveillance system and 59.5% found it easy to implement the system. A total of 32 death notification forms were reviewed and of these, 31 forms were forwarded to the national office and all did not reach the national office on time. Average completeness of notification forms was 76.0% and 53.1% of the forms had all the necessary accompanying documents. Reporting each maternal death was estimated to cost $28.65 in Mutare district. CONCLUSION: The strongest components of the maternal mortality surveillance system in Mutare district were usefulness and acceptability. Timeliness and completeness were the weaker components of the system. The system was found to be simple; however, resources were not adequately available in all health facilities.

Evaluation of the acute flaccid paralysis (AFP) surveillance system, Gokwe North district, Zimbabwe, 2015: a descriptive cross sectional study.

INTRODUCTION: AFP surveillance was adopted globally as a key strategy for monitoring the progress of the polio eradication initiative. Gokwe North district with an estimated 119 655 children <15 years detected 2 cases, 4 cases and 1 case of AFP in 2012, 2013 and 2014 respectively against a target of 5 cases per year. We therefore set out to evaluate the system and find out why it was failing to detect at least 5 cases per year. METHODS: A descriptive cross sectional study was carried out. All three hospitals in the district were purposively selected. Twelve of the nineteen health facilities were randomly selected and forty nine health workers were purposively recruited. An interviewer administered questionnaire and key informant interview guide were used to collect data. Quantitative data was analysed using Epi info. RESULTS: Out of the 49 respondents, 17(34.7%) knew the target age group for AFP surveillance. Twelve (24.5%) knew the number of notification forms to be filled. Seven (14.3%) and ten (20.4%) respondents knew when to follow up an AFP case and when an AFP case should be followed up and completely notified and investigated respectively. Forty one (83.7%) respondents were not trained on AFP surveillance. Nineteen (39%) had AFP notification forms at the clinic and 33(67%) had displayed AFP case definitions. All the 22 health facilities in the district participate in AFP surveillance; however, all have hard to reach areas. Seventeen (34.7%) reportedly took public health actions based on AFP data. CONCLUSION: The system was found to be useful, simple, acceptable, timely, unstable, not representative and not sensitive. The system was threatened by lack of health worker knowledge and community active search. Advocacy, communication and social mobilization on AFP surveillance might improve the performance of the system in Gokwe North district.

Evaluation of the adverse drug reaction surveillance system Kadoma City, Zimbabwe 2015.

INTRODUCTION: Medicines have the potential to cause adverse drug reactions and because of this Zimbabwe monitor reactions to medicines through the Adverse Drug Reaction Surveillance System. The Medicines Control Authority of Zimbabwe monitors reactions to medicines through the Adverse Drugs Reactions Surveillance System. The system relies on health professionals to report adverse drug reactions to maximize patient safety. We report results of an evaluation of the Adverse Drugs Reactions Surveillance System in Kadoma District. METHODS: A descriptive cross-sectional study was conducted using the updated CDC guidelines in six health facilities in Kadoma City. Data were collected using a pretested interviewer administered questionnaire, checklists and records review. Data was analyzed using Epi InfoTM to calculate frequencies and means. Qualitative data were analyzed manually. Written informed consent was obtained from all study participants. RESULTS: The surveillance system did not meet up to its objectives as it failed to detect the adverse drug reactions and there was no monitoring of increases in known events. Fewer than half (43%) of the participants were aware of at least 2 objectives of the surveillance system but 83% of health workers willing to participate. However the system was not acceptable, 79% did not perceive the system to be necessary with the majority saying ''why should we fill in the forms when the reactions were already known or minor''. Though the system was supposed to identify potential patient risk factors for particular types of events health workers were reluctant to participate as evidenced by only one form filled out of 20 reactions experienced in the district. The system was simple as the notification form has 16 fields which require easily obtainable information from the patient records. CONCLUSION: The surveillance system was not useful and was not acceptable to health workers but was simple and stable. Health workers lacked knowledge. Sharing of results with the Medicines Control Authority of Zimbabwe through the Matrons facilitated training of health workers in Kadoma City. Health workers were encouraged to notify any drug reaction and to completely fill in the notification forms. Patients were also encouraged to report any drug reaction to health care workers.

Factors associated with severe malaria among children below ten years in Mutasa and Nyanga districts, Zimbabwe, 2014-2015.

INTRODUCTION: Severe malaria is a rare life threatening illness. Only a small proportion of patients with clinical malaria progress to this medical emergency. On reviewing 61 malaria death investigation forms submitted to the provincial office in 2014, 22(36%) were children below ten years who succumbed to severe malaria. Mutasa and Nyanga Districts reported 73% of these deaths. This study was conducted to determine factors associated with severe malaria so as to come up with evidence based interventions to prevent severe malaria and associated mortality. METHODS: A 1:2 unmatched case control study was conducted. A case was defined as a child 10 years and below, who was admitted at Hauna (Mutasa) or Nyanga District Hospitals between September 2014 and May 2015 with a primary diagnosis of severe malaria. Controls were children of similar age with uncomplicated malaria. Permission to conduct the study was sought and granted by the Medical Research Council of Zimbabwe (Approval number B/874), Joint Research Ethics Committee, Health Studies Office and the Manicaland Directorate Institutional Review Board. Written informed consent was sought from all caregivers of enrolled children. Interviewer administered questionnaires were used to ascertain exposures. RESULTS: A total of 52 cases and 104 controls were enrolled into the study. The median age of cases was 4 years (Q1=3, Q3=9) and 6 years for controls (Q1=3, Q3=8). The Case Fatality Rate among cases was 28.8%. The independent risk factors for severe malaria were; distance >10km to the nearest health facility [Adjusted Odds Ratio (aOR)=14.35, 95% CI=1.30, 158.81], duration of symptoms before seeking medical care >2 days [aOR=9.03, 95% CI=2.21, 36.93], having comorbidities [aOR=5.38, 95% CI=1.90, 15.19], staying in a house under construction [aOR=4.51, 95%CI=1.80, 11.32] and duration of illness before receiving antimalarial medicines >24 hours [aOR=3.82, 95% CI=1.44, 10.12]. Owning at least one ITN in the household [aOR=0.32, 95% CI=0.11, 0.95] and having a mother as a caregiver [aOR=0.23, 95% CI=0.09, 0.76] were independently protective of severe malaria. Being undernourished [Odds Ratio (OR)=10.13, 95% CI=1.04, 98.49] and being female [OR=0.27, 95% CI=0.08, 0.96] were associated with mortality owing to severe malaria. CONCLUSION: Factors associated with severe malaria and mortality owing to severe malaria identified in this study are consistent with other studies. Caregiver healthcare seeking behaviours, patient related factors and health system related factors are important determinants of severe malaria among children. There is need for regular health education campaigns emphasizing on malaria prevention, signs and symptoms and benefits of seeking medical care immediately for sick children.

Malaria morbidity and mortality trends in Manicaland province, Zimbabwe, 2005-2014.

INTRODUCTION: Zimbabwe targets reducing malaria incidence from 22/1000 in 2012 to 10/1000 by 2017, and malaria deaths to near zero by 2017. As the country moves forward with the malaria elimination efforts, it is crucial to monitor trends in malaria morbidity and mortality in the affected areas. In 2013, Manicaland Province contributed 51% of all malaria cases and 35% of all malaria deaths in Zimbabwe. This analysis describes the trends in malaria incidence, case fatality and malaria outpatient workload compared to the general outpatient workload. METHODS: We analyzed routinely captured malaria data in Manicaland Province for the period 2005 to 2014. Epi Info version 7 was used to calculate chi-square trends for significance and Microsoft Excel was used to generate graphs. Permission to analyze the data was sought and granted by the Provincial Medical Directorate Institutional Review Board of Manicaland and the Health Studies office. RESULTS: Malaria morbidity data for the period 2005-2014 was reviewed and a total of 947,462 cases were confirmed during this period. However, malaria mortality data was only available for the period 2011-2014 and cumulatively 696 deaths were reported. Malaria incidence increased from 4.4/1,000 persons in 2005 to 116.3/1,000 persons in 2014 (p<0.001). The incidence was higher among females compared to males (p-trend<0.001) and among the above five years age group compared to the under-fives (p-trend<0.001). The proportion of all Outpatient Department attendances that were malaria cases increased 30 fold from 0.3% in 2005 to 9.1% in 2014 (p-trend<0.001). The Case Fatality Rate also increased 2-fold from 0.05 in 2011 to 0.1 in 2014 (p-trend<0.001). CONCLUSION: Despite current malaria control strategies, the morbidity and mortality of malaria increased over the period under review. There is need for further strengthening of malaria control interventions to reduce the burden of the disease.

Evaluation of severe malaria case management in Mazowe District, Zimbabwe, 2014.

INTRODUCTION: Malaria is a preventable and curable disease. Mazowe district had been experiencing a lower malaria transmission rate in comparison to other districts in the Mashonaland Central province but it experienced a huge outbreak in the 2013-2014 rainy seasons with a case fatality rate (CFR) of 0.21%. This CFR was the highest in the province and it was twice as much as the national CFR (0.12%) for the same period. We evaluated severe malaria case management in Mazowe district to determine if practice is as per standard treatment guidelines. METHODS: A descriptive cross sectional study was conducted in Mazowe district using the Logical Framework approach. District Health Executives (DHE) members, nurses and severe malaria case notes were purposively and conveniently selected into the study. Key informant Interviews and review of case notes were carried out. All data were analysed using Epi Info 3.5.1.to calculate means and frequencies. Permission to conduct the study was obtained from the Mashonaland Central Provincial Medical Directorate (PMD) Institutional Ethical Review Board (IRB). RESULTS: The median age in years of the cases was 16 (Q1=7.3; Q3=30.8) and up to 58.1% of the cases were female. Inputs including staff, medicines and medical and laboratory equipment for severe case management were inadequate in the district. Only 60% of severe cases were diagnosed using blood slides and up to 95.6% of cases presented with one or more of the clinical signs of severe malaria. All severe cases were treated using correct anti-malarial and analgesic doses. Patient monitoring was not done as per prerequisite intervals and up to 5% of cases died. The health workers had above average knowledge on severe malaria. CONCLUSION: Severe malaria case management inputs were inadequate in the district. For many cases, the district did not follow complicated malaria treatment guidelines for diagnosis, treatment and monitoring. Untrained staff needs training in Severe Malaria Case Management and monitoring of commodity stocks needs to be strengthened.

An evaluation of the proposed organisation restructuring at Kadoma city, 2015.

INTRODUCTION: Restructuring is the corporate management term for the act of reorganizing the legal, operational, or other structures of a company for the purpose of making it more profitable or better organized for its present needs. However, preparing an organization to accept and welcome any change is crucial. There is concern though over poor service delivery, untimely payment of workers, top management structure which is thought to be top heavy and employee costs taking (58%) of total expenditure. METHODS: A descriptive cross sectional study was carried out. A cost benefit analysis was used to assess the cost and benefits of the proposed retrenchment exercise. A descriptive cross sectional study survey was conducted to assess the workers' perceptions towards the proposed restructuring exercise. A pretested self-administered questionnaire was used for data collection and data were analysed using EpiInfoTM (CDC 2012).Written informed consent was obtained from all study participants. RESULTS: Sixty nine percent of the respondents were males. The median years working for the organisation was 8 years (Q1=1; Q3=17). The total income was surpassed by expenditure with USD$11 000 and 52% of expenditures was going towards employment costs. A midyear financial review showed that 1% was channeled towards capital expenditure 2% on repairs and maintenance and employee costs accounting to 58% of all incurred expenditure. Current departmental salary budget amounted to USD 3,3million dollars. Estimated salary costs for the proposed departmental structures amount to USD 3,8 million dollars. Comparison of the current and proposed structure showed that the proposed structure costs USD$486 000 more. Projected benefits of the proposed structure aims to improve service delivery from 60%-85% . Unlike managers, lower levels workers did not want the exercise to be carried out. CONCLUSION: The proposed structure has higher costs than the current structure but with more benefits in terms of service delivery. Generally workers perceived restructuring negatively and did not want it done.

Factors associated with contracting malaria in Ward 29 of Shamva District, Zimbabwe, 2014.

BACKGROUND: Malaria cases at Wadzanayi Clinic in Shamva District, Zimbabwe, increased drastically, surpassing the epidemic threshold, in week four of December 2013. This rise was sustained, which necessitated an investigation of the outbreak. OBJECTIVES: To identify risk factors and system weaknesses to improve epidemic preparedness and response. METHODS: An unmatched 1:1 case-control study was conducted in Ward 29 of Shamva District in Zimbabwe. Epidemic preparedness and response were assessed using the Zimbabwean epidemic preparedness and response guidelines. RESULTS: The sociodemographic characteristics of all participants were similar, except for gender. The risk factors for contracting malaria were performing early morning chores (odds ratio (OR) 2.75; 95% confidence interval (CI) 1.20 - 6.32), having a body of water near the home (OR 3.41; 95% CI 1.62 - 7.20) and having long grass near the home (OR 2.61; 95% CI 1.10 - 6.37). Protective factors were staying indoors at night (OR 0.13; 95% CI 0.06 - 0.28) and staying in a sprayed home (OR 0.36; 95% CI 0.21 - 0.92). All cases were diagnosed with a malaria rapid diagnostic test. All complicated cases were treated with quinine. Four out of 58 uncomplicated cases were treated with quinine. The rest were treated with co-artemether. There was no documentation of the outbreak response by the district health executive. Respraying (indoor residual spraying) was carried out, with a coverage of 78% of rooms sprayed. One nurse out of seven at Wadzanayi Clinic was trained in integrated disease surveillance and response, and malaria case management. District malaria thresholds were outdated. Malaria commodities such as drugs and sprays did not have reorder limits. CONCLUSION: This study re-emphasises the importance of environmental- and personal-level factors as determinants of malaria. Poor out-break preparedness and response may have propagated the malaria outbreak in this setting. Health education and the use of mosquito repellants should be emphasised. Larvicide may reduce the malaria burden. Epidemic preparedness and response need to be strengthened. Outbreak investigation remains important. This study emphasises the need for malaria interventions to be tailored to locally prevailing determinants to avert outbreaks.

Factors associated with late presentation for HIV/AIDS care in Harare City, Zimbabwe, 2015.

BACKGROUND: Despite widespread awareness and publicity concerning Human Immunodeficiency Virus (HIV) care and advances in treatment, many patients still present late in their HIV disease. Preliminary review of the Antiretroviral Therapy (ART) registers at Wilkins and Beatrice Road Hospitals, both located in Harare, indicated that 67 and 71 % of patients enrolled into HIV/AIDS care presented late with baseline CD4 of <200 cells/uL and/or WHO stage 3 and 4 respectively. We therefore sought to explore factors associated with late presentation in Harare City. METHODS: We conducted a 1:1 unmatched case control study where a case was an HIV positive individual (>18 years) with a baseline CD4 of <200/uL or who had WHO clinical stage 3 or 4 at first presentation to OI/ART centres in 2014 and; a control was HIV positive individual (>18 years) who had a baseline CD4 of >200/uL or WHO clinical stage 1 or 2 at first presentation in 2014. Written informed consent was obtained from all study participants. RESULTS: A total of 268 participants were recruited (134 cases and 134 controls). Independent risk factors for late presentation for HIV/AIDS care were illness being reason for test (Adjusted Odds Ratio [aOR] =7.68, 95 % CI = 4.08, 14.75); Being male (aOR = 2.84, 95 % CI = 1.50, 5.40) and; experienced HIV stigma (aOR = 2.99, 95 % CI = 1.54, 5.79). Independent protective factors were receiving information on HIV (aOR = 0.37, 95 % CI = 0.18, 0.78) and earning more than US$250 per month (aOR = 0.32, 95 % CI = 0.76, 0.67). Median duration between first reported HIV positive test result and enrolment into pre-ART care was 2 days (Q1 = 1 day; Q3 = 30 days) among cases and 30 days (Q1 = 3 days; Q3 = 75 days) among controls. CONCLUSION: Late presentation for HIV/AIDS care in Harare City was a result of factors that relate to the patient's sex, reason for getting a test, receiving HIV related information, experiencing stigma and monthly income. Based on this evidence we recommended targeted interventions to optimize early access to testing and enrolment into care.

Factors associated with male involvement in the prevention of mother to child transmission of HIV, Midlands Province, Zimbabwe, 2015 - a case control study.

BACKGROUND: Uptake of and adherence to the prevention of mother to child transmission of HIV (PMTCT) interventions are a challenge to most women if there is no male partner involvement. Organizations which include the National AIDS Council and the Zimbabwe AIDS Prevention Project- University of Zimbabwe have been working towards mobilizing men for couple HIV testing and counseling (HTC) in antenatal care (ANC). In 2013, Midlands province had 19 % males who were tested together with their partners in ANC, an increase by 9 % from 2011. However, this improvement was still far below the national target, hence this study was conducted to determine the associated factors. METHODS: A1:1 unmatched case control study was conducted. A case was a man who did not receive HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. A control was a man who received HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. Simple random sampling was used to select 112 cases and 112 controls. Epi Info statistical software was used to analyze data. Written informed consent was obtained from each study participant. RESULTS: Independent factors that predicted male involvement in PMTCT were: having been previously tested as a couple (aOR) 0.22, 95 % CI = 0.12, 0.41) and having time to visit the clinic (aOR) 0.41, 95 % CI = 0.21, 0.80). Being afraid of knowing one's HIV status (aOR 2.22, 95 % CI = 1.04, 4.76) was independently associated with low male involvement in PMTCT. CONCLUSION: Multiple factors were found to be associated with male involvement in PMTCT. Routine PMTCT educational campaigns in places where men gather, community based couple HTC and accommodating the working class during weekends are essential in fostering male involvement in PMTCT thereby reducing HIV transmission to the baby.

Factors associated with malaria infection in Honde valley, Mutasa district, Zimbabwe, 2014: a case control study.

BACKGROUND: In January of 2014, an outbreak of malaria was declared in the Honde Valley region of Mutasa District in Zimbabwe. The area has a hot, temperate climate and high rainfall pattern ideal for vector breeding and malaria transmission. Gravity fed irrigation channels span the valley creating a number of breeding sites for malaria vectors, mosquitoes. Malaria outbreaks have been a common occurrence in the district over the past few years despite the district meeting set targets for prevention interventions like indoor residual spraying (IRS) with pyrethroids and long lasting insecticidal nets distribution. The objectives of this study were to describe the outbreak by person, place and time, to assess the community's knowledge on malaria transmission, signs and symptoms and treatment and to tease out factors associated with malaria infection in the district. METHODS: An unmatched case-control study was carried out. Interviewer guided questionnaires were administered to residents of the valley who met the inclusion criteria in order to tease out possible factors associated with malaria infection. A case was defined as a resident of Honde Valley with a history of malaria symptoms and a confirmed diagnosis from 13 January 2014 to 26 January 2014. A control was a resident of Mutasa District who was present in the district during the time of the outbreak but did not develop symptoms of malaria. A total of 87 cases and 87 controls were enrolled. RESULTS: Cases and controls were comparable in terms of socio-demographic characteristics and knowledge on malaria transmission, treatment and prevention. Risk factors associated with contracting malaria during the outbreak were being under the age of 5 years (OR = 9.92, CI 1, 2-80, 1), not using mosquito repellents (OR = 8, 25 CI 3, 78-18, 0), having outdoor activities before dawn and after dusk (OR = 2, 81 CI 1,04-7, 6). Having received indoor residual spraying in ones house was a risk factor for contracting malaria (OR = 1, 68 CI 0, 74-3, 83). This finding was not statistically significant. Sleeping under an insecticidal net and wearing protective clothing when outdoors after dusk were protective factors against contracting malaria (OR = 0, 27 CI 0, 12-0, 59 and OR = 0, 12 CI 0, 06-0, 25 respectively). All cases were treated according to the national malaria case management guidelines. CONCLUSIONS: Risk factors for contracting malaria were being under the age of 5 years, outdoor activities at night and not using mosquito repellents. Net use was a protective factor from contracting malaria in Mutasa District. Indoor residual spraying with pyrethroids in Honde Valley was not a protective factor against contracting malaria.
