Trend of Soil-Transmitted Helminths in Ethiopian Children: A Systematic Review and Meta-Analysis (2000-2018).

BACKGROUND: Ethiopia is one of the tropical countries with a heavy burden of soil-transmitted helminths. As a result, the nation has been implementing mass drug administration, water, sanitation, and hygiene and health extension programs to control those parasites. Hence, updated data about the prevalence and trend of parasites over time has a pivotal role to assess the success of existing control programs. METHODS: Studies conducted between 2000 and 2018 were searched from PubMed, Google Scholar, and local journals for systematic reviews and meta-analysis following the PRISMA guideline and checklists. Eligible studies were selected based on preset inclusion and exclusion criteria. The quality of the included studies was assessed using the Newcastle-Ottawa Scale in meta-analysis. Heterogeneity between studies was assessed using the Cochran Q test and I 2 test statistics based on the random effect model. Comprehensive meta-analysis (CMA 2.0) was used to calculate the pooled prevalence, and metaregression was run to assess the trend of parasite prevalence over time. RESULTS: Thirty-eight studies recruiting 16,266 participants were included in the review. The pooled prevalence of intestinal parasites was 52.0% (95% CI: 44.4-59.5). Amhara region was with the highest prevalence (60.3%; 95% CI: 50.1-69.6). Among soil-transmitted helminths, Ascaris lumbricoides (11.2%; 95% CI: 8.4-14.8) was with the highest pooled prevalence followed by hookworms (10.4%; 95% CI: 7.9-13.7) and Trichuris trichiura (3.6%; 95% CI: 2.4-5.4). Metaregression analysis revealed that all soil-transmitted helminths did not show a significantly decreasing trend over time (p > 0.05). CONCLUSION: Despite various control efforts having been made, soil-transmitted helminths are of high distribution, and their prevalence is not significantly decreasing in Ethiopia. Hence, other control approaches like community-led sanitation should be integrated with mass drug administration to achieve the national goal of soil-transmitted helminth elimination by 2025.

Vulvovaginitis Prevalence Among Women in Gondar, Northwest Ethiopia: Special Emphasis on Aerobic Vaginitis Causing Bacterial Profile, Antimicrobial Susceptibility Pattern, and Associated Factors.

BACKGROUND: Genital tract infections are posing a series of public health challenges for women in both developed and developing countries. Microbial infections of the vagina can lead to serious medical complications such as preterm labor, amniotic fluid infection, premature rupture of the fetal membranes, and low birth weight of the neonate, leading to high perinatal morbidity and mortality. In Ethiopia, limited information is found on the burden, antimicrobial susceptibility profile and associated factors for aerobic vaginitis. Thus, this study was aimed to determine the burden of AV, antimicrobial susceptibility profile of aerobic bacterial isolates and associated factors among women attending Gondar town health facilities, northwest Ethiopia. METHODS: A health facility-based cross-sectional study was conducted on 214 study participants from February 1 to May 31, 2019. For all consecutive women, demographic variables were collected using a structured questionnaire and two vaginal swabs for each were collected. The diagnosis of AV and BV was based on the composite score of Donders and Nugent criteria, respectively. All bacteria were isolated and characterized by conventional culture techniques. The antimicrobial susceptibility pattern was performed using the disc diffusion technique. Logistic regression, univariate and multivariate analysis were carried out. A p-value ≤ 0.05 at 95% CI was considered as statistically significant. RESULTS: The overall prevalence of vulvovaginitis among women was 50%. The identified aetiologies of vulvovaginitis were bacterial vaginosis (35.5%), candidiasis (23.8%), aerobic vaginitis (22.9%) and trichomoniasis (3.3%). Aerobic bacteria, especially Enterococcus faecalis and Escherichia coli, were predominantly isolated in the vaginal samples. The prevalence of the multidrug resistance rate was 38.98%. The isolated Gram positive bacteria were sensitive to antibiotics like vancomycin, cefoxitin, ciprofloxacin, clindamycin, and gentamicin, whereas the Gram negative bacteria isolates were sensitive to ciprofloxacin, gentamicin and meropenem. CONCLUSION: The high burden of bacterial vaginosis and aerobic vaginitis was reported. Therefore, regular screening of women using microbiological diagnosis should be promoted. The common bacteria isolated were Enterococcus faecalis and Escherichia coli. Additionally, antibiotics like vancomycin, cefoxitin, ciprofloxacin, clindamycin, gentamicin, and meropenem were shown to have good action against the majority of bacteria isolates.

Extended-Spectrum ß-Lactamase and Carbapenemase Producing Gram-Negative Bacilli Infections Among Patients in Intensive Care Units of Felegehiwot Referral Hospital: A Prospective Cross-Sectional Study.

BACKGROUND: Owing to the specific risk profile of its residents, intensive care units (ICUs) are the best place for selection pressure and the epicenter for resistance development and dissemination. Infections with ß-lactamase releasing Gram-negative bacilli (GNB) at ICUs are an emerging global threat. This study dogged the magnitude of extended-spectrum ß-lactamase (ESBL) and carbapenemase releasing Gram-negative bacilli infections and associated factors among patients in the ICUs of Felegehiwot Referral Hospital, Ethiopia. METHODS: A cross-sectional study was done through February to June 2020. Wound swabs, urine, blood and sputum samples were collected from patients in the ICUs symptomatic for infections while excluding those under coma and shock. Bacterial species were verified using standard microbiological methods. Carbapenemase and ESBL production were identified using modified carbapenem inactivation and combined disk diffusion methods, respectively. Multivariable analysis was calculated for factors associated with ESBL production. P-value < 0.05 was taken as cut-off for statistical significance. RESULTS: Out of 270 patients in the ICU, 67 (24.8%) and 14 (5.2%) had infections with ESBL and carbapenemase releasing GNB, respectively. The most frequent ESBL producing isolates were P. aeruginosa (100%), E. cloacae (100%), K. pneumoniae (82.8%) and E. coli (64%). The predominant carbapenemase producer isolates were K. pneumoniae (27.6%) and E. cloacae (33.3%). Overall, 77 (81.1%) of species were multi-drug resistant. All GNB species were 100% resistant to tetracycline and ampicillin. They are also resistant to cefuroxime, ceftazidime, sulfamethoxazole-trimethoprim and cefotaxime. Prior hospitalization (AOR = 5.5, CI = 2.63-11.46), support with medical care devices (AOR = 23.7, CI = 4.6-12) and arterial intravenous catheterization (AOR = 2.7, CI = 1.3-5.3) had significant association with ß-lactamase producing GNB infection. CONCLUSION: Infection with ESBL and carbapenemase producing Gram-negative bacilli linked with an alarming degree of multi-drug resistant isolates is a major healthcare threat among patients in ICUs. Hence, strict adherence to infection prevention practices and wise use of antibiotics are recommended to slow the spread of antimicrobial resistance.

Quality of care for tuberculosis patients in public health facilities of Debre Tabor town, Northwest Ethiopia.

BACKGROUND: Even though there are different tuberculosis (TB) prevention and control measures implemented globally including Ethiopia, TB is still major public health problem. This is partly due to compromised quality of care delivered for tuberculosis patients in health facilities (HFs) during diagnosis, treatment and follows-up. Thus this study is intended to determine the quality of care delivered for TB patients in all public HFs of Debre Tabor town, Northwest Ethiopia. METHODS: Cross sectional study was conducted from January to May 2018. Data were collected with face-to-face interview and TB registration book review using structured questionnaire and checklist respectively. Collected data was entered and processed using SPSS and P value <0.05 was considered statistically significant. The quality of care for each HF was graded as very good, good, moderate, poor and very poor if HFs achieve [90-100%], [80-90%), [70-80%), [60-70%) and <60% of performance indicators respectively using Donabedian structure, process and outcome model of health care quality. RESULTS: All HFs have sputum collection area, enough microscopic slide, at least one functional microscope and sufficient anti TB drug supply. But HFs lack backup laboratory stains. Overall structural aspects of quality of care in all HFs were very poor achieving 42.5-52.9% structural performance indicators out of 100%. Similarly the overall process aspects of quality of care was poor in all public HFs which achieved 60-68.9% of the scores out of 100%. In the study; 68.9%, 54.5% and 80.6% of Medical Laboratory, pharmacy and other healthcare workers (HWs) provided correct response respectively on TB causative agent, risk factor, transmission, treatment, prevention, case management and case finding strategies. HWs who knew at least two TB case finding strategies in DTH was significantly higher than those HWs working in Health Centers (P = 0.004). On the other hand, except Ginbot 20 HC, HFs was graded as good by scoring 86.6-89.3% of performance indicators on the outcome aspects of quality of care. In all HFs studied, all TB patients' unit TB registration number, sex, age, TB category, treatment initiation date and intensive phase treatment start year were properly registered. Moreover 110 (78%) and 147 (69%) contact person address in DTH and HCs was properly registered on TB unit register book respectively with no statistical difference in hospital and HCs (P = 0.063). There was proper TB patients' address registration in hospital than HCs studied (P< 0.001). CONCLUSIONS: The outcome aspects of quality of care for TB patients in all HFs were promising. But structural & process aspects of quality of care was compromised which necessitate different corrective actions to be taken by different stakeholders to enhance quality of care for TB patients in public HFs studied. Moreover based on the study findings, continuous supply of drugs, laboratory equipment and reagents, availing current guideline/s in HFs, providing up-to-date training for HWs on TB and proper documentation are important to improve quality of care provided for TB patients.

Carriage rate of Neisseria meningitidis, antibiotic susceptibility pattern and associated risk factors among primary school children in Gondar town, Northwest Ethiopia.

BACKGROUND: Globally, in 2012, about 1.2 million estimated cases were reported with ~ 135,000 deaths annually. In Ethiopia, specifically in our study area, limited information is found on the oropharyngeal carriage, antimicrobial resistance pattern, and associated risk factors for N. meningitidis among school children. So, the aim of this study was to assess oropharyngeal carriage rate of N. meningitidis, antibiotic susceptibility pattern and associated risk factors among primary school children in Gondar town, Northwest Ethiopia. METHODS: A cross sectional study was conducted from January to April, 2019 in Gondar town. Multi stage simple random sampling technique was used. A total of 524 oropharyngeal swabs were collected using sterile plastic cotton swabs. Modified Thayer Martin media was used for primary isolation. Antimicrobial susceptibility pattern was done based on Kirby-Bauer method on Muller-Hinton agar supplemented with 5% sheep blood. Multidrug resistance was defined as resistance of an isolate to two or more antimicrobial classes tested. Logistic regression model was used to see the association between dependent variables (Carriage rate of Neisseria meningitidis, Serogroups of Neisseria meningitidis and Antimicrobial susceptibility patterns) and independent variables (Socio-demographic data and risk factors). Variables with a P- value ≤0.2 during bivariable analysis was taken to multivariable analysis to check significant association of meningococcal carriage with risk factors. Finally, a P-value < 0.05 was considered as statistically significant. Data was summarized using numbers, percentages and tables. RESULTS: A total of 53(10.1%) (CI: 7.6-12.8) N. meningitidis isolates were identified. Serogroup A 13 (24.5%) was the most prevalent followed by Y/W135 11(20.7%) whereas serogroup B 4(7.6%) was the least identified serotype. Meningococcal isolates were resistant to ciprofloxacin (45.3%) and trimethoprim-sulfamethoxazole (73.6%). Overall, most of meningococcal isolates showed about 32(60.4%) multidrug resistance. Meningococcal carriage rate was significantly associated with family size, tonsillectomy, passive smoking, number of students per class, sharing utensils, history of visiting healthcare institutions, and indoor kitchen. CONCLUSION: This study highlights the need for reinforcement of case-based, laboratory confirmed surveillance of N. meningitidis carriage in Ethiopian elementary school students to enable mapping of distribution of serotypes of the causative organisms across the country and determine the current potential necessity of vaccination.

Seroprevalence of transfusion transmissible viral infections (HIV, HBV and HCV) among voluntary blood donors at University of Gondar Comprehensive Specialized Hospital, Gondar; Northwest Ethiopia.

BACKGROUND: Human immunodeficiency virus, hepatitis B virus and hepatitis C virus are among the greatest threats to blood safety for the recipient. They are also the leading cause of death, chronic and life-threatening abnormalities. Therefore, this study was aimed to assess the Sero-prevalence of HIV, Hepatitis B and C virus among blood donors at the University of Gondar Comprehensive Specialized Hospital. METHODS: A retrospective cross-sectional study was used to estimate the seroprevalence of HIV, Hepatitis B and C virus among blood donors at the University of Gondar Comprehensive Specialized Hospital from May-July 2018. Screening of HIV, HBV, and HCV was done by using the Enzyme-Linked ImmunoSorbent Assay. Records of 5983 first time blood donors were collected and reviewed by using a checklist from registration book. Data was entered in statistical package EP Info version 3.5.1, and data cleaned and analyzed using the statistical package SPSS version 16.0. RESULTS: Of 5983 blood donors, 85.5% (5118/5983) donors were males and 14.5% (865/5983) were females. The median age was 27 years and the highest blood donations age category was between 20 to 51.2% (29/5983) followed by 30 to 39 years of age, 21.6% (1295/5983). The prevalence of HIV, HBV and HCV infections were 2.5% (95% CI: 1.07-2.398), 4.1% (95% CI: 0.461-1.053) and 1.6% (95% CI: 0.845-3.354), respectively. HIV infection was significantly associated with gender (p = 0.021, x2 = 5.358) and HCV infection with age group (p = 0.003, x2 = 17.673). Of all donated blood, 8.2% (489/5983) had serological evidence for at least one of the screened pathogens and 58 (0.96%) of them had multiple infections. CONCLUSIONS: This study showed a significant prevalence of HIV, HBV, and HCV among blood donors, 2.5% (147/5983), 4.1% (244/5983) and 1.6% (98/5983), respectively. Therefore, strict selection of blood donors with an emphasis on getting voluntary blood donors, and highly sensitive and specific tests for screening of blood donors for HIV, HBV, and HCV using standard methods are highly recommended to ensure the safety of blood for the recipient.

High prevalence of extended-spectrum beta-lactamase-producing Gram-negative pathogens from patients attending Felege Hiwot Comprehensive Specialized Hospital, Bahir Dar, Amhara region.

BACKGROUND: Infections caused by extended-spectrum beta-lactamases (ESBL) producing Gram-negative bacteria has emerge as a global threat in clinical practices. The treat is more serious in developing countries due to inappropriate use, poor adherence, use of counterfeit, sub-standard antibiotics and poor infection control practices. Data on ESBL producing Gram-negative bacteria are limited in developing countries including Ethiopia. The aim of this study was therefore, to describe the burden of ESBL producing Gram negative pathogens isolated from patients attending at Felege Hiwot Comprehensive Specialized Hospital, Bahir Dar, Amhara region. MATERIALS AND METHODS: A total of 532 clinical samples of blood, urine, stool, wound, abscess, ear discharge, nasal discharge, cervical discharge and body fluid specimens were aseptically collected and bacteriologically processed. Identification of the bacterial species was performed using an automated system (Vitek-2 Compact 27530, USA) and antibiotic susceptibility test was determined by disk diffusion method and selection of antibiotics were in accordance with CLSI guidelines. The MDR pattern of the Gram-negative pathogens was assessed using phenotypic methods of ESBL and carbapenemase production following standard procedure. RESULT: A total of 532 samples were processed and 263 pathogens were isolated. Of these, 185 (70.3%) were Gram-negative and 78 (29.7%) Gram-positive. Of the Gram-negative bacteria the high proportion of the isolates were identified from blood 146/185 (78.9%) and 29/185 (15.7%) were from urine cultures. The most common isolate in all clinical samples was Klebsiella pneumoniae 97/185 (52.4%) followed by Escherichia coli 23/185 (12.4%), Acinetobacter baumannii 15/185 (17.6%) and Enterobacter aerogenes 12/185(6.5%). Of the total Gram negatives, the prevalence of MDR was 148/185 (80.0%). Of the MDR isolates the prevalence of ESBL producers were, 127/148 (85.8%) and 24/148 (16.2%) were carbapenemase producers. CONCLUSION AND RECOMMENDATION: Prevalence of MDR and ESBL producing Gram-negative pathogens in this hospital is alarmingly high. Therefore, continuous monitoring of the problem with effective infection prevention and careful selection of empirical therapy are warranted in the study area.

Occupational exposure to blood and body fluids and associated factors among health care workers at the University of Gondar Hospital, Northwest Ethiopia.

BACKGROUND: Occupational exposure to blood and body fluids (BBFs) is a serious concern for health care workers (HCWs) and presents a major risk factor for transmission of infectious diseases such as hepatitis B virus (HBV), hepatitis C virus, and human immune deficiency virus. The main objective of this study was to assess the magnitudes of occupational exposure of blood and body fluids and associated factors among health workers at the University of Gondar Hospital. METHODS: An institution-based cross-sectional study was conducted from 1 February to 31 May 2017 at the University of Gondar Hospital. A total of 282 health care workers were selected by simple random sampling technique. Descriptive data was presented as absolute number with percentage, and multivariate analysis was used to assess the statistical association between associated factors and occupational exposure to BBFs. A P value of < 0.05 was considered as statistical significant. RESULT: A total of 282 HCWs participated with the mean (±SD) age of 30.51 ± 5.86 year. Of the total, 58.5% (165) and 42.2% (119) of the study participants had been exposed to BBFs splash and needlestick injury (NSI) in their lifetime, respectively. However, 39.0% (110) and 20.6% (58) of the HCWs were exposed to splash and NSI in the past 1 year, respectively. Not wearing eye goggle, lack of training on infection prevention, taking of HBV vaccination, and recapping of used needle were risk factors associated with BBFs splash exposure, whereas taking HBV vaccination and recapping of used needle were associated risk factors with NSI exposure. CONCLUSION: This study showed a high percentage of occupational exposure to blood and body fluids among health care workers. Not wearing eye goggle, HBV vaccine status, and recapping needles were found to be independent predictors of occupational exposure to BBFs among HCWs. Therefore, relevant stakeholders need to formulate strategies to create a favorable working environment and increase their adherence to universal precautions.

Prevalence, risk factors and antifungal susceptibility pattern of Candida species among pregnant women at Debre Markos Referral Hospital, Northwest Ethiopia.

BACKGROUND: Candida is the commonest opportunistic fungi in human. Candida species cause diverse types of diseases. Vaginal candidiasis has been reported as one of the most common type of fungal diseases among pregnant women. However; In Ethiopia, due to scarcity of data, much has not been documented regarding the prevalence of Candida among pregnant women. OBJECTIVE: This study aimed to determine the prevalence, possible risk factors and antifungal susceptibility profile of Candida species among pregnant women attending Debre Markos Referral Hospital, Northwest Ethiopia. METHOD: A cross-sectional study was conducted from February to May 2017. A total of 384 pregnant women were included using a systematic random sampling technique. Vaginal specimens were collected, inoculated on Candida HiV eg culture Medium and incubated at 37 °C for 24 h.Colonies were identified using standard microbiological methods and selected for further Candida Species identification using Hi Chrome agar and germ tube test. Fungal suspensions were made and adjusted at 0.5% MacFarland standard. Modified Kirby-Bauer disk diffusion technique was used for antifungal susceptibility. Data was entered, cleaned using Ep info version 7.1and transported to Statistical Packages for Social Sciences (SPSS) version 21 for analysis. Descriptive statistics and logistic regression were performed. P. value < 0.05 at 95% confidence interval was considered as statistically significant. RESULT: From a total of 384 study participants, 96 (25%) were positive for Candida species. The predominant Candida species was Candida albicans 54(56.25%) followed by Candida krusei 21(21.9%), Candida glabrata 17(17.7%), Candida tropicalis 1(1%) and 3(3.1%) were other Candida species. Contraceptive use (AOR: 0.394; 95% CI = 0.20-0.74) and prolonged antibiotic uses (AOR: 0.393; 95% CI = 0.21-0.72) were risk factors. All isolates except Candida krusei were 100% susceptible to amphotericin-B. Resistance rate was high against itraconazole and Ketoconazole 55(57.3%). CONCLUSION: The prevalence of Candida species among symptomatic pregnant women was significantly higher than asymptomatic pregnant women. Age group between 26 and 40 years was significantly associated with Candida infection. Amphotericin B was the most sensitive antifungal drug. High rate of multiple drugs resistant Candida species was detected. Therefore Symptomatic women should be routinely screened and treated.

Prevalence and antimicrobial susceptibility patterns of extended spectrum beta-lactamase producing Entrobacteriaceae in the University of Gondar Referral Hospital environments, northwest Ethiopia.

OBJECTIVE: This study aimed at assessing the magnitude, distribution, and the antimicrobial susceptibility of the extended spectrum beta-lactamase producing Entrobacteriaceae in the University of Gondar Referral Hospital environments. RESULTS: Out of a total of 384 samples, 14.8% were ESBL producing Entrobacteriaceae, where 42.10% Klebsiella pneumoniae, 35.09% Escherchia coli and 7.01% Proteus mirabilis were the predominant isolates. Most ESBL producing isolates, that is, 24.56, 22.8, and 22.8% were found from waste water, sinks and bedside tables respectively. All ESBL producing Entrobacteriaceae were found to be resistant to ceftriaxone, ceftazidime, cefpirome, cefpodoxime, and amoxicillin with Clavulanic acid. Resistance rate was also high for non-beta-lactam antimicrobials, like chloramphenicol (70.18%), cotrimoxazole (64.91%), norfloxacin (42.10%), ciprofloxacin (43.86%), and gentamicin (19.30%).

Nasal Carriage Rate, Antimicrobial Susceptibility Pattern, and Associated Factors of Staphylococcus aureus with Special Emphasis on MRSA among Urban and Rural Elementary School Children in Gondar, Northwest Ethiopia: A Comparative Cross-Sectional Study.

INTRODUCTION: Staphylococcus aureus is a Gram-positive, catalase-positive, and coagulase-positive bacterial species commonly found on the skin and in the nose of most healthy individuals. The anterior nares of nose are the most frequent carriage sites for S. aureus in both adults and children. Methicillin resistance among S. aureus isolates has steadily increased worldwide. OBJECTIVE: The main objective of this study was to determine nasal carriage rate, antimicrobial susceptibility pattern, and associated risk factors of Staphylococcus aureus with special emphasis on MRSA among urban and rural elementary school children in Gondar, Northwest Ethiopia. METHOD: A community based comparative cross-sectional study was conducted on 622 urban and rural elementary school children in Gondar from January 1st to March 30th, 2018. Data was collected using a questionnaire and nasal swab samples were collected by sterile cotton tip swab moistened with sterile normal saline. Collected samples were inoculated on mannitol salt agar and incubated aerobically at 37°C for 24 hrs. S. aureus was confirmed by observing colony characteristics and biochemical tests. MRSA was detected using cefoxitin disc by Modified Kirby-Bauer disk diffusion technique. Finally data was entered, cleared, and checked using Epi-info version 7 and exported to SPSS version 20 for analysis. Odds ratio and logistic regression were used for statistical association. P-value ≤ 0.05 at 95% CI was considered for statistical association. RESULT: Of the 622 school children, the overall prevalence of S. aureus was 143/622 (23%). Of them, 14/143 (9.79%) were MRSA. The carriage rate in urban schools was 83/622 (13.3%) whereas it was 60/622 (9.6%) in rural schools. The prevalence of MRSA among urban schools, 9.1%, was higher than their urban counterparts, 0.7%. Gentamycin, clindamycin, and ciprofloxacin were the most effective whereas penicillin and tetracycline were resistant. Children's fathers' educational status and number of children in class room were significantly associated with S. aureus but only living in urban of children significantly associated with MRSA. CONCLUSION: This study showed high prevalence of S. aureus and MRSA, 143/622 (23%) and 14/143 (9.79%), respectively. So, decolonization of nasal carriers of MRSA and reducing the number of students per classroom should be addressed. Moreover, regular large scale survey should be conducted to assess the burden and intervene accordingly.

Multidrug resistant tuberculosis: prevalence and risk factors in districts of metema and west armachiho, Northwest Ethiopia.

BACKGROUND: Multi drug resistant tuberculosis (MDR-TB) is an emerging challenge for TB control programs globally. According to World health organization, 2012 report Ethiopia stands 15(th) out of the 27 high priority countries in the world and 3(rd) in Africa. Updated knowledge of the magnitude of MDR-TB is so substantial to allocate resources, and to address prevention and control measures. Therefore, the aim of this study was to assess the prevalence of MDR-TB and associated risk factors in West Armachiho and Metema districts of North Gondar. METHODS: A cross-sectional study was conducted in West Armachiho and Metema districts between February 01 and June 25, 2014. A total of 124 consecutive smear positive pulmonary tuberculosis patients were included in the study. Socio-demographic and possible risk factor data were collected using a semi-structured questionnaire. Drug susceptibility testing was first performed for rifampicin using GeneXpert MTB/RIF. For those rifampicin resistant strains, drug susceptibility testing was performed for both isoniazid and rifampicin to identify MDR-TB using the proportional method on LJ media. Data were analyzed using statistical Package SPSS version 20; binary logistic regression was used to assess the association. P-values < 0.05 were considered as statistically significant. RESULTS: Of 124 smear-positive pulmonary TB patients, 117 (94.4 %) were susceptible to Rifampicin, while 7 (5.7 %) were confirmed to be resistant to Rifampicin and Isoniazid. The overall prevalence of MDR-TB was 5.7 % (2.3 % among new cases and 13.9 % among previously treated cases). History of previous treatment (OR = 7, P = 0.025) was significantly associated risk factor for MDR-TB. CONCLUSION: The overall prevalence of MDR-TB was 5.7 % among cases at five health centers and a history of previous treatment was found to be a risk factor for being infected by an MDR-TB strain. Therefore, maximizing early case detection and treatment, strengthening TB infection control activities and proper implementation of DOTS are recommended to reduce the burden of MDR-TB.
