Evaluating event-based surveillance capacity in Africa: Use of the Africa CDC scorecard, 2022-2023.

Introduction: Event-based surveillance (EBS) is a critical component of Early Warning, Alert and Response (EWAR) capacity needed for outbreak prevention and control. To better understand existing EBS and monitor the progress of capacity-building efforts over time, Africa CDC developed an EBS scorecard as part of a revision to the EBS Framework. Methods: We distributed the scorecard to African Union (AU) Member States (MSs). Survey responses from the MSs' human health sector were aggregated, cleaned, and analysed. MS, regional, and continental EBS capacity was assessed. Results: Between 21 July 2022 and 4 April 2023, a total of 63 respondents representing 49 (89%) of 55 MSs completed the survey. Given Africa CDC's public health mandate, we acknowledged the importance of One Health collaboration in MSs but focused on and analysed only the human health sector responses. Thirty-four (71%) MSs stated having EBS in place; hotline was the most common type of EBS implemented (76%). Seventeen (50%) MSs reported multisectoral, One Health collaboration as part of EBS implementation. Scorecard outcomes showed a minimal (score of <60%) to average (score between 60-80%) level of EBS capacity in 29 and five (5) MSs respectively. Discussion: Current EBS capacity levels need to be strengthened in Africa to ensure the continent remains prepared for future public health threats. The Africa CDC EBS scorecard provides a useful way to measure and track this capacity over time. Results can be used to advocate for and target resources for capacity building to foster public health emergency preparedness efforts.

Questionnaire Survey on Knowledge, Attitude and Practices on COVID 19 Outbreak Among Veterinarians in Nigeria.

Coronavirus Disease 2019 (COVID-19), a viral pneumonia-like disease caused by novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) started in Wuhan, Hubei Province of China on December 31st 2019, and assumed a pandemic status; infecting about 30 million people, with a mortality in excess of 957,000 as at 20st September, 2020. This study assessed the knowledge, attitude, and practices concerning COVID-19 among veterinarians with a view to detecting variables that may hinder their effective contributions towards the management and control of COVID-19 outbreak in Nigeria.The study found that male veterinarians had significantly good knowledge (p=0.012, OR=0.157, CI=0.03-0.66) and attitude (OR=18.415, CI=1.45-5.16, P=0.011) towards COVID-19 than female counterparts. Similar results were also recorded regarding practices (OR=2.941, CI=1.03-8.36, P=0.043). Educational qualification was found to be significantly associated with attitude of veterinarians in respect of COVID-19 prevention (OR=0.473, CI=0.073-0.011, P=0.006). Thus, gender (male) was found to be independent predictors of good knowledge, attitude and practices regarding COVID-19. In addition, educational qualification was also found to be an independent predictor of attitude of veterinarians regarding COVID-19 control. Veterinarians generally had good knowledge about the epidemiology, diagnosis, treatment and prevention of COVID-19. However, despite their knowledge, the level of willingness of veterinarians to support national response activities was still poor. This study advocated for a collaborative efforts (one-health) between medics and vets in tackling future pandemics/infectious diseases like COVID-19. In addition, since most vet knows the basics of infectious diseases like COVID-19, they can be deployed for national response activities.

Group versus individual antenatal and first year postpartum care: Study protocol for a multi-country cluster randomized controlled trial in Kenya and Nigeria.

Background: Antenatal care (ANC) in many low- and middle-income countries is under-utilized and of sub-optimal quality. Group ANC (G-ANC) is an intervention designed to improve the experience and provision of ANC for groups of women (cohorts) at similar stages of pregnancy. Methods: A two-arm, two-phase, cluster randomized controlled trial (cRCT) (non-blinded) is being conducted in Kenya and Nigeria. Public health facilities were matched and randomized to either standard individual ANC (control) or G-ANC (intervention) prior to enrollment. Participants include pregnant women attending first ANC at gestational age <24 weeks, health care providers, and sub-national health managers. Enrollment ended in June 2017 for both countries. In the intervention arm, pregnant women are assigned to cohorts at first ANC visit and receive subsequent care together during five meetings facilitated by a health care provider (Phase 1). After birth, the same cohorts meet four times over 12 months with their babies (Phase 2). Data collection was performed through surveys, clinical data extraction, focus group discussions, and in-depth interviews. Phase 1 data collection ended in January 2018 and Phase 2 concludes in November 2018. Intention-to-treat analysis will be used to evaluate primary outcomes for Phases 1 and 2: health facility delivery and use of a modern method of family planning at 12 months postpartum, respectively. Data analysis and reporting of results will be consistent with norms for cRCTs. General estimating equation models that account for clustering will be employed for primary outcome analyzes. Results: Overall 1,075 and 1,013 pregnant women were enrolled in Nigeria and Kenya, respectively. Final study results will be available in February 2019. Conclusions: This is the first cRCT on G-ANC in Africa. It is among the first to examine the effects of continuing group care through the first year postpartum.

Mortality Among Confirmed Lassa Fever Cases During the 2015-2016 Outbreak in Nigeria.

OBJECTIVES: To determine factors associated with mortality among confirmed Lassa fever cases. METHODS: We reviewed line lists and clinical records of laboratory-confirmed cases of Lassa fever during the 2016 outbreak in Nigeria to determine factors associated with mortality. We activated an incident command system to coordinate response. RESULTS: We documented 47 cases, 28 of whom died (case fatality rate [CFR] = 59.6%; mean age 31.4 years; SD = ±18.4 years). The youngest and the oldest were the most likely to die, with 100% mortality in those aged 5 years or younger and those aged 55 years or older. Patients who commenced ribavirin were more likely to survive (odds ratio [OR] = 0.1; 95% confidence interval [CI] = 0.03, 0.50). Fatality rates went from 100% (wave 1) through 69% (wave 2) to 31% (wave 3; χ2 for linear trend: P < .01). Patients admitted to a health care center before incident command system activation were more likely to die (OR = 4.4; 95% CI = 1.1, 17.6). The only pregnant patient in the study died postpartum. CONCLUSIONS: Effective, coordinated response reduces mortality from public health events. Attention to vulnerable groups during disasters is essential. Public Health Implications. Activating an incident command system improves the outcome of disasters in resource-constrained settings.
