Item The effect of Brucellosis in Wildlife in four Major National Parks of Uganda(BMC Veterinary Research, 2021) Aruho, Robert; MacLeod, Ewan T.; Manirakiza, Leonard; Rwego, Innocent B.Brucellosis is a contagious zoonotic disease of great public health and economic significance especially in developing countries. The disease affects humans and several species of livestock and wildlife. Studies on Brucellosis in wildlife in Uganda have been limited to single populations particularly in Queen Elizabeth National Park. This study aimed at estimating the percentage of positive samples of Brucella spp. in wildlife in four major national parks of Uganda. This was a retrospective survey which utilized archived samples collected from wildlife during the annual disease surveillance activities between 2013 and 2017.A total of 241 samples from seven species namely African buffalo (Syncerus caffer, n = 109), African elephant (Loxodonta africana, n = 22), giraffe (Giraffa camelopardalis rothschildi, n = 41), Uganda kob (Kobus kob thomasi, n = 36), lion (Panthera leo, n = 6), plain zebra (Equus quagga, n = 25), and bushbuck (Tragelaphus scriptus, n = 2), were tested for antibodies using the Rose Bengal Plate Test. The overall percentage of positive samples in the four national parks was 31.1% (75/241; 95% CI: 25.6–37.2). Kidepo Valley National Park had a significantly higher percentage of positive samples of 55.9% (19/34; 95% CI: 39.5–71.1) compared to other sampled national parks (p < 0.05). Lions had significantly higher percentage of positive samples at 66.7% (4/6) than African buffalo at 48.6% (53/109, p < 0.0001). There were no antibodies for Brucella spp. detected in African elephant and bushbuck.This study shows variations in percentage of positive samples with Brucella spp. between species and across national parks and notably a high percentage with Brucella spp. in wildlife in Uganda than that recorded elsewhere in sub-Saharan region of Africa. Potential for transmission to other wildlife and spill over to livestock is high especially in national parks with high livestock-wildlife interaction.Item The impact of the increase in import verifcation fees on local production capacity of selected medicines in Uganda(Journal of Pharmaceutical Policy and Practice, 2023) Rajab, Kalidi; Onen, Solomon; Nakitto, Diana Kesi; Serwanga, Allan; Mutasaaga, Joseph; Manirakiza, Leonard; Mwesigwa, Denis; Nahamya, David; Ndagije, Helen ByomireThe local manufacture of pharmaceuticals is an opportunity to develop a broader manufacturing and knowledge-based economy and reduce over dependence on imports. To promote local production, the Ugandan government introduced Buy Uganda Build Uganda policy geared towards promoting use of locally manufactured goods. It also increased import verification fees in 2017 for 37 selected locally manufactured essential medicines from 2 to 12% to discourage importation of these medicines. This study assessed the impact of the increase in verification fees on local production capacity of the medicines.Item Lowland Grazing And Marburg Virus Disease (MVD) Outbreak In Kween District, Eastern Uganda(BMC Public Health, 2019) Siya, Aggrey; Bazeyo, William; Tuhebwe, Doreen; Tumwine, Gabriel; Ezama, Arnold; Manirakiza, Leonard; Kugonza, Donald R.; Rwego, Innocent B.Uganda is one of the few countries in Africa that has been experiencing outbreaks of viral hemorrhagic fevers such as Ebola, Marburg and Crimean-Congo Hemorrhagic fevers. In 2017 Uganda experienced a Marburg Virus Disease (MVD) outbreak with case fatality rate of 100% in Kween district. Although hunting for wild meat was linked to the MVD outbreak in Kween district, less was reported on the land use changes, especially the changing animal grazing practices in Kween district.Through Makerere University One Health graduate fellowship program with attachment to Uganda Red Cross Society, a study was conducted among the agricultural communities to elucidate the risk behaviors in Kween district that can be linked to the 2017 Marburg disease outbreak.Results show that although a few elderly participants ascribed fatal causes (disobedience to gods, ancestors, and evil spirits) to the MVD outbreak during FGDs, majority of participants linked MVD to settling in caves (inhabited by Fruit Bats) during wet season as upper belts are extensively used for crop production leaving little space for animal grazing. Members also noted side activities like hunting for wild meat during this grazing period that could have predisposed them to Marburg Virus.There is need to integrate One Health concepts within agricultural extension service provision in Uganda so as to enhance the management of such infectious diseases.Item Preparedness of health care systems for Ebola outbreak response in Kasese and Rubirizi districts, Western Uganda(BMC public health, 2021) Kibuule, Michael; Sekimpi, Deogratias; Agaba, Aggrey; Ali Halage, Abdullah; Jonga, Michael; Manirakiza, Leonard; Kansiime, Catherine; Travis, Dominic; Pelican, Katharine; Rwego, Innocent B.The level of preparedness of the health care workers, the health facility and the entire health system determines the magnitude of the impact of an Ebola Virus Disease (EVD) outbreak as demonstrated by the West African Ebola outbreak. The objective of the study was to assess preparedness of the health care facilities and identify appropriate preparedness measures for Ebola outbreak response in Kasese and Rubirizi districts in western Uganda. Methods: A cross sectional descriptive study was conducted by interviewing 189 health care workers using a structured questionnaire and visits to 22 health facilities to determine the level of health care system preparedness to EVD outbreak. District level infrastructure capabilities, existence of health facility logistics and supplies, and health care workers’ knowledge of EVD was assessed. EVD Preparedness was assessed on infrastructure and logistical capabilities and the level of knowledge of an individual health work about the etiology, control and prevention of EVD. Results: Twelve out of the 22 of the health facilities, especially health center III’s and IV’s, did not have a line budget to respond to EVD when there was a threat of EVD in a nearby country. The majority (n = 13) of the facilities did not have the following: case definition books, rapid response teams and/or committees, burial teams, and simulation drills. There were no personal protective equipment that could be used within 8 h in case of an EVD outbreak in fourteen of the 22 health facilities. All facilities did not have Viral Hemorrhagic Fever (VHF) incident management centers, isolation units, guidelines for burial, and one-meter distance between a health care worker and a patient during triage. Overall, 54% (n = 102) of health care workers (HCWs) did not know the incubation period of EVD. HCWs who had tertiary education (aOR = 5.79; CI = 1.79–18.70; p = 0.003), and were Christian (aOR = 10.47; CI = 1.94–56.4; p = 0.006) were more likely to know about the biology, incubation period, causes and prevention of EVD. Conclusions: Feedback on the level of preparedness for the rural districts helps inform strategies for building capacity of these health centers in terms of infrastructure, logistics and improving knowledge of health care workers.Item Prescription of Levofloxacin and Moxifloxacin in Select Hospitals in Uganda: A Pilot Study to Assess Guideline Concordance(Antibiotics, 2020) Nambasa, Victoria; Ndagije, Helen B.; Serwanga, Allan; Manirakiza, Leonard; Atuhaire, Joanitah; Nakitto, Diana; Kiguba, Ronald; Figueras, AlbertIn Uganda, national tuberculosis (TB) treatment guidelines were revised to include the newer generation fluoroquinolones among the second-line treatment options for multidrug-resistant TB. This study was designed to analyze if the prescription of these quinolones is compliant with country recommendations. Methods: This was an observational retrospective study of consumption data for 2017 and 2018 across four selected regional referral hospitals. The sources of consumption data were hospital pharmacy stock cards and the dispensing register. The medical files of patients who had been prescribed fluoroquinolones were also assessed to study compliance with the Uganda Clinical Guidelines and the British National Formulary (BNF). Results: None of the 371 levofloxacin prescriptions analyzed complied with the Uganda Clinical Guidelines, although 250 (67.3%) were prescribed for indications included in the BNF. According to WHO prescription indicators, only 220 (59.3%) prescriptions were appropriate. Conclusion: The prescription of levofloxacin and moxifloxacin increased in the hospitals studied, but in a high proportion of cases, they were not compliant with country recommendations. The findings call for the strengthening of national antimicrobial stewardship programs.Item A serological survey of brucellosis in wildlife in four major National Parks of Uganda(BMC Veterinary Research, 2021) Aruho, Robert; MacLeod, Ewan T.; Manirakiza, Leonard; Rwego, Innocent B.Brucellosis is a contagious zoonotic disease of great public health and economic significance especially in developing countries.
