Item Cutaneous anthrax associated with handling carcasses of animals that died suddenly of unknown cause: Arua District, Uganda, January 2015–August 2017(PLoS Neglected Tropical Diseases, 2021) Loy Aceng, Freda; Riolexus Ario, Alex; Alitubeera, Phoebe Hilda; Matinda Neckyon, Mukasa; Kadobera, Daniel; Sekamatte, Musa; Okethwangu, Denis; Bulage, Lilian; Harris, Julie R.; Nguma, Willy; Birungi Ndumu, Deo; Buule, Joshua; Nyakarahuka, Luke; Zhu, Bao-PingAnthrax is a zoonotic disease that can be transmitted to humans from infected animals. During May–June 2017, three persons with probable cutaneous anthrax were reported in Arua District, Uganda; one died. All had recently handled carcasses of livestock that died suddenly and a skin lesion from a deceased person tested positive by PCR for Bacillus anthracis. During July, a bull in the same community died suddenly and the blood sample tested positive by PCR for Bacillus anthracis. The aim of this investigation was to establish the scope of the problem, identify exposures associated with illness, and recommend evidencebased control measures. Methods A probable case was defined as acute onset of a papulo-vesicular skin lesion subsequently forming an eschar in a resident of Arua District during January 2015–August 2017. A confirmed case was a probable case with a skin sample testing positive by polymerase chain reaction (PCR) for B. anthracis. Cases were identified by medical record review and active community search. In a case-control study, exposures between case-patients and frequency- and village-matched asymptomatic controls were compared. Key animal health staff were interviewed to learn about livestock deaths. Results There were 68 case-patients (67 probable, 1 confirmed), and 2 deaths identified. Cases occurred throughout the three-year period, peaking during dry seasons. All cases occurred following sudden livestock deaths in the villages. Case-patients came from two neighboring sub-counties: Rigbo (attack rate (AR) = 21.9/10,000 population) and Rhino Camp (AR = 1.9/ 10,000). Males (AR = 24.9/10,000) were more affected than females (AR = 0.7/10,000). Persons aged 30–39 years (AR = 40.1/10,000 population) were most affected. Among all cases and 136 controls, skinning (ORM-H = 5.0, 95%CI: 2.3–11), butchering (ORM-H = 22, 95%CI: 5.5–89), and carrying the carcass of livestock that died suddenly (ORM-H = 6.9, 95% CI: 3.0–16) were associated with illness. Conclusions Exposure to carcasses of animals that died suddenly was a likely risk factor for cutaneous anthrax in Arua District during 2015–2017. The recommendations are investigation of anthrax burden in livestock, prevention of animal infections through vaccinations, safe disposal of the carcasses, public education on risk factors for infection and prompt treatment of illness following exposure to animals that died suddenly.Item Early cases of SARS-CoV-2 infection in Uganda: epidemiology and lessons learned from risk-based testing approaches – March-April 2020(Globalization and Health, 2020) Migisha, Richard; Kwesiga, Benon; Mirembe, Bernadette B.; Amanya, Geofrey; Kabwama, Steven N.; Kadobera, Daniel; Bulage, Lilian; Nsereko, Godfrey; Wadunde, Ignatius; Tindyebwa, Tonny; Lubwama, Bernard; Kagirita, Atek A.; Kayiwa, John T.; Lutwama, Julius J.; Boore, Amy L.; Harris, Julie R.; Kyobe Bosa, HenryOn March 13, 2020, Uganda instituted COVID-19 symptom screening at its international airport, isolation and SARS-CoV-2 testing for symptomatic persons, and mandatory 14-day quarantine and testing of persons traveling through or from high-risk countries. On March 21, 2020, Uganda reported its first SARS-CoV-2 infection in a symptomatic traveler from Dubai. By April 12, 2020, 54 cases and 1257 contacts were identified. We describe the epidemiological, clinical, and transmission characteristics of these cases. Methods: A confirmed case was laboratory-confirmed SARS-CoV-2 infection during March 21–April 12, 2020 in a resident of or traveler to Uganda. We reviewed case-person files and interviewed case-persons at isolation centers. We identified infected contacts from contact tracing records. Results: Mean case-person age was 35 (±16) years; 34 (63%) were male. Forty-five (83%) had recently traveled internationally (‘imported cases’), five (9.3%) were known contacts of travelers, and four (7.4%) were community cases. Of the 45 imported cases, only one (2.2%) was symptomatic at entry. Among all case-persons, 29 (54%) were symptomatic at testing and five (9.3%) were pre-symptomatic. Among the 34 (63%) case-persons who were ever symptomatic, all had mild disease: 16 (47%) had fever, 13 (38%) reported headache, and 10 (29%) reported cough. Fifteen (28%) case-persons had underlying conditions, including three persons with HIV. An average of 31 contacts (range, 4–130) were identified per case-person. Five (10%) case-persons, all symptomatic, infected one contact each. Conclusion: The first 54 case-persons with SARS-CoV-2 infection in Uganda primarily comprised incoming air travelers with asymptomatic or mild disease. Disease would likely not have been detected in these persons without the targeted testing interventions implemented in Uganda. Transmission was low among symptomatic persons and nonexistent from asymptomatic persons. Routine, systematic screening of travelers and at-risk persons, and thorough contact tracing will be needed for Uganda to maintain epidemic controlItem Evaluation of Public Health Surveillance Systems in Refugee Settlements in Uganda, 2016–2019: Lessons Learned(Conflict and Health, 2022) Ario, Alex Riolexus; Barigye, Emily Atuheire; Nkonwa, Innocent Harbert; Bulage, Lilian; Okello, Paul Edward; Kizito, Susan; Kwesiga, Benon; Kasozi, JuliusCivil wars in the Great Lakes region resulted in massive displacement of people to neighboring countries including Uganda. With associated disease epidemics related to this conflict, a disease surveillance system was established aiming for timely detection of diseases and rapid response to outbreaks. We describe the evaluation of and lessons learned from the public health surveillance system set up in refugee settlements in Uganda. We conducted a cross-sectional survey using the US Centers for Disease Control and Prevention Updated Guidelines for Evaluating Public Health Surveillance Systems and the Uganda National Technical Guidelines for Integrated Disease Surveillance and Response in four refugee settlements in Uganda—Bidibidi, Adjumani, Kiryandongo and Rhino Camp. Using semi-structured questionnaires, key informant and focus group discussion guides, we interviewed 53 health facility leaders, 12 key personnel and 224 village health team members from 53 health facilities and 112 villages and assessed key surveillance functions and attributes. All health facilities assessed had key surveillance staff; 60% were trained on Integrated Disease Surveillance and Response and most village health teams were trained on disease surveillance. Case detection was at 55%; facilities lacked standard case definitions and were using parallel Implementing Partner driven reporting systems. Recording was at 79% and reporting was at 81%. Data analysis and interpretation was at 49%. Confirmation of outbreaks and events was at 76%. Preparedness was at 72%. Response was at 34%. Feedback was at 82%. Evaluate and improve the system was at 67%. There was low capacity for detection, response and data analysis and interpretation of cases (< 60%). The surveillance system in the refugee settlements was functional with many performing attributes but with many remaining gaps. There was low capacity for detection, response and data analysis and interpretation in all the refugee settlements. There is need for improvement to align surveillance systems in refugee settlements with the mainstream surveillance system in the country. Implementing Partners should be urged to offer support for surveillance and training of surveillance staff on Integrated Disease Surveillance and Response to maintain effective surveillance functions. Functionalization of district teams ensures achievement of surveillance functions and attributes. Regular supervision of and support to health facility surveillance personnel is essential. Harmonization of reporting improves surveillance functions and attributes and appropriation of funds by government to districts to support refugee settlements is complementary to maintain effective surveillance of priority diseases in the northern and central part of Uganda.Item Factors associated with acute watery diarrhea among children aged 0–59 months in Obongi District, Uganda, April 2022: A case–control study(Elsevier Ltd, 2024-04) Juniour Nsubuga, Edirisa; Kirabo, Jireh; Kwiringira, Andrew; Andaku, Linus; Magona Nerima, Saharu; Nsubuga, Fred; Nakazzi, Rashida; Kwesiga, Benon; Bulage, Lilian; Kadobera, Daniel; Edward Okello, Paul; Riolexus Ario, AlexAbstract • Poor caregiver hand hygiene linked to acute watery diarrhea in children. • Source of water in a home was associated with acute watery diarrhea in children. • Rotavirus vaccination only, not enough to prevent acute watery diarrhea in children. • Educate communities on handwashing at critical times, using clean water & soap. • Stresses need for treated pipped/tap water in every household.Item Factors Associated with Utilisation of Couple HIV Counselling and Testing Among HIV‑Positive Adults in Kyoga Fishing Community Uganda, May 2017: Cross Sectional Study(AIDS and behavior, 2017) Nakiire, Lydia; Kabwama, Steven; Majwala, Robert; Bbale, Joy Kusiima; Makumbi, Issa; Kalyango, Joan; Kihembo, Christine; Masiira, Ben; Bulage, Lilian; Kadobera, Daniel; Ario, Alex Riolexus; Nsubuga, PeterCouple HIV counseling and testing (CHCT) is key in preventing heterosexual HIV transmission and achievement of 90-90-90 UNAIDS treatment targets by 2020. We conducted secondary data analysis to assess utilization of CHCT and associated factors using logistic regression. 58/134 participants (49%) had ever utilized CHCT. Disclosure of individual HIV results to a partner [aOR = 16; 95% CI: (3.6–67)], residence for > 1 < 5 years [aOR = 0.04; 95% CI (0.005–0.33)], and none mobility [aOR = 3.6; 95% CI (1.1–12)] were significantly associated with CHCT. Age modified relationship between CHCT and disclosure (Likelihood-ratio test LR chi2 = 4.2 (p value = 0.041). Disclosure of individual HIV results with a partner and residence for more than 1 year improved utilization of CHCT; mobility reduced the odds of CHCT. Interventions should target prior discussion of individual HIV results among couples and mobile populations to increase CHCT.Item Factors Associated with Utilisation of Couple HIV Counselling and Testing Among HIV‑Positive Adults in Kyoga Fishing Community Uganda, May 2017: Cross Sectional Study(AIDS and behavior, 2020) Nakiire, Lydia; Kabwama, Steven; Majwala, Robert; Kusiima Bbale, Joy; Makumbi, Issa; Kalyango, Joan; Kihembo, Christine; Masiira, Ben; Bulage, Lilian; Kadobera, Daniel; Riolexus Ario, Alex; Nsubuga, Peter; Wanyenze, RhodaCouple HIV counseling and testing (CHCT) is key in preventing heterosexual HIV transmission and achievement of 90-90- 90 UNAIDS treatment targets by 2020.

B.; Wanyenze, Rhoda K.; Kiyaga, CharlesDespite the growing number of people on antiretroviral therapy (ART), there is limited information about virological non suppression and its determinants among HIV-positive (HIV+) individuals enrolled in HIV care in many resource-limited settings. We estimated the proportion of virologically non-suppressed patients, and identified the factors associated with virological non suppression. Methods: We conducted a descriptive cross-sectional study using routinely collected program data from viral load (VL) samples collected across the country for testing at the Central Public Health Laboratories (CPHL) in Uganda. Data were generated between August 2014 and July 2015. We extracted data on socio-demographic, clinical and VL testing results. We defined virological non-suppression as having ≥1000 copies of viral RNA/ml of blood for plasma or ≥5000 copies of viral RNA/ml of blood for dry blood spots. We used logistic regression to identify factors associated with virological non-suppression. Results: The study was composed of 100,678 patients; of these, 94,766(94%) were for routine monitoring, 3492(4%) were suspected treatment failures while 1436(1%) were repeat testers after suspected failure. The overall proportion of non suppression was 11%. Patients on routine monitoring registered the lowest (10%) proportion of nonsuppressed patients. Virological non-suppression was higher among suspected treatment failures (29%) and repeat testers after suspected failure (50%). Repeat testers after suspected failure were six times more likely to have virological non-suppression (ORadj = 6.3, 95%CI = 5.5–7.2) when compared with suspected treatment failures (ORadj = 3.3, 95%CI = 3.0–3.6). The odds of virological non-suppression decreased with increasing age, with children aged 0–4 years (ORadj = 5.3, 95%CI = 4.6–6.1) and young adolescents (ORadj = 4.1, 95%CI = 3.7–4.6) registering the highest odds. Poor adherence (ORadj = 3.4, 95%CI = 2.9–3.9) and having active TB (ORadj = 1.9, 95%CI = 1.6–2.4) increased the odds of virological non-suppression. However, being on second/third line regimens (ORadj = 0.86, 95%CI = 0.78–0.95) protected patients against virological non-suppression. Conclusion: Young age, poor adherence and having active TB increased the odds of virological non-suppression while second/third line ART regimens were protective against non-suppression. We recommend close follow up and intensified targeted adherence support for repeat testers after suspected failure, children and adolescents.Item Fatal Rift Valley Fever Outbreak Caused By Exposure To Meat FromSick And Dead Livestock: Uganda, July 2018(Research Square, 2021) Mirembe, Bernadette B; Ario, Alex R.; Birungi, Doreen; Bulage, Lilian; Kisaakye, Esther; Kwesiga, Benon; Kabwama, Steven N.; Muwanguzi, David; Kadobera, Daniel; Balinandi, Steven; Birungi, Deo N.Page2/12AbstractBackground: Rift Valley Fever (RVF) is a viral hemorrhagic fever that can be fatal to humans and livestock. During June-October 2018,reported RVF cases increased sharply in eight western and central Ugandan districts. We investigated to identify the scope of theoutbreak, determine risk factors, and recommend control measures.Methods: We deItem Investigation of Marburg Virus Disease Outbreak in Kween District, Eastern Uganda, 2017(PLoS neglected tropical diseases, 2019) Ario, Alex Riolexus; Makumbi, Issa; Nkonwa, Innocent Herbert; Eyu, Patricia; Opio, Denis Nixon; Nakiire, Lydia; Kwesiga, Benon; Kadobera, Daniel; Tusiime, Patrick; Bulage, Lilian; Zhu, Bao-Ping; Aceng, Jane RuthIn October 2017, a blood sample from a resident of Kween District, Eastern Uganda, tested positive for Marburg virus. Within 24 hour of confirmation, a rapid outbreak response was initiated. Here, we present results of epidemiological and laboratory investigations.A district task force was activated consisting of specialised teams to conduct case finding, case management and isolation, contact listing and follow up, sample collection and testing, and community engagement. An ecological investigation was also carried out to identify the potential source of infection. Virus isolation and Next Generation sequencing were performed to identify the strain of Marburg virus.Seventy individuals (34 MVD suspected cases and 36 close contacts of confirmed cases) were epidemiologically investigated, with blood samples tested for MVD. Only four cases met the MVD case definition; one was categorized as a probable case while the other three were confirmed cases. A total of 299 contacts were identified; during follow- up, two were confirmed as MVD. Of the four confirmed and probable MVD cases, three died, yielding a case fatality rate of 75%. All four cases belonged to a single family and 50% (2/4) of the MVD cases were female. All confirmed cases had clinical symptoms of fever, vomiting, abdominal pain and bleeding from body orifices. Viral sequences indicated that the Marburg virus strain responsible for this outbreak was closely related to virus strains previously shown to be circulating in Uganda.This outbreak of MVD occurred as a family cluster with no additional transmission outside of the four related cases. Rapid case detection, prompt laboratory testing at the Uganda National VHF Reference Laboratory and presence of pre-trained, well-prepared national and district rapid response teams facilitated the containment and control of this outbreak within one month, preventing nationwide and global transmission of the disease.Item Large outbreak of Jimsonweed (Datura stramonium) poisoning due to consumption of contaminated humanitarian relief food: Uganda, March–April 2019(BMC public health, 2022) Mutebi, Ronald R.; Ario, Alex R.; Nabatanzi, Maureen; Kyamwine, Irene B.; Wibabara, Yvette; Muwereza, Peter; Eurien, Daniel; Kwesiga, Benon; Bulage, Lilian; Kabwama, Steven N.; Kadobera, Daniel; Henderson, Alden; Callahan, John H.; Croley, Timothy R.; Knolhoff, Ann M.; Mangrum, John B.; Handy, Sara M.; McFarland, Melinda A.; Fong Sam, Jennifer L.; Harris, Julie R.; Zhu, Bao‑PingJimsonweed (Datura stramonium) contains toxic alkaloids that cause gastrointestinal and central nervous system symptoms when ingested. This can be lethal at high doses. The plant may grow together with leguminous crops, mixing with them during harvesting. On 13 March 2019, more than 200 case-patients were admitted to multiple health centres for acute gastrointestinal and neurologic symptoms. We investigated to determine the cause and magnitude of the outbreak and recommended evidence-based control and prevention measures. Methods: We defined a suspected case as sudden onset of confusion, dizziness, convulsions, hallucinations, diarrhoea, or vomiting with no other medically plausible explanations in a resident of Napak or Amudat District from 1 March—30 April 2019. We reviewed medical records and canvassed all villages of the eight affected subcounties to identify cases. In a retrospective cohort study conducted in 17 villages that reported the earliest cases, we interviewed 211 residents about dietary history during 11–15 March. We used modified Poisson regression to assess suspected food exposures. Food samples underwent chemical (heavy metals, chemical contaminants, and toxins), proteomic, DNA, and microbiological testing in one national and three international laboratories. Results: We identified 293 suspected cases; five (1.7%) died. Symptoms included confusion (62%), dizziness (38%), diarrhoea (22%), nausea/vomiting (18%), convulsions (12%), and hallucinations (8%). The outbreak started on 12 March, 2–12 h after Batch X of fortified corn-soy blend (CSB +) was distributed. In the retrospective cohort study, 66% of 134 persons who ate CSB + , compared with 2.2% of 75 who did not developed illness ( RRadj = 22, 95% CI = 6.0–81). Samples of Batch X distributed 11–15 March contained 14 tropane alkaloids, including atropine (25-50 ppm) and scopolamine (1-10 ppm). Proteins of Solanaceae seeds and Jimsonweed DNA were identified. No other significant laboratory findings were observed. Conclusion: This was the largest documented outbreak caused by food contamination with tropane alkaloids. Implicated food was immediately withdrawn. Routine food safety and quality checks could prevent future outbreaks.Item Level and Determinants of Adherence to COVID-19 Preventive Measures in the First Stage of the Outbreak in Uganda(International journal of environmental research and public health, 2020) Amodan, Bob O.; Bulage, Lilian; Katana, Elizabeth; Ario, Alex R.; Siewe Fodjo, Joseph N.; Colebunders, Robert; Wanyenze, Rhoda K.We conducted an online survey in the first two months of the Coronavirus Disease 2019 (COVID-19) epidemic in Uganda to assess the level and determinants of adherence to and satisfaction with the COVID-19 preventive measures recommended by the government. We generated Likert scales for adherence and satisfaction outcome variables and measured them with four preventive measures, including handwashing, wearing face masks, physical distancing, and coughing/sneezing hygiene. Of 1726 respondents (mean age: 36 years; range: 12–72), 59% were males, 495 (29%) were adherent to, and 545 (32%) were extremely satisfied with all four preventive measures. Adherence to all four measures was associated with living in Kampala City Centre (AOR: 1.7, 95% CI: 1.1–2.6) and receiving COVID-19 information from health workers (AOR: 1.2, 95% CI: 1.01–1.5) or village leaders (AOR: 1.4, 95% CI: 1.02–1.9). Persons who lived with younger siblings had reduced odds of adherence to all four measures (AOR: 0.75, 95% CI: 0.61–0.93). Extreme satisfaction with all four measures was associated with being female (AOR: 1.3, 95% CI: 1.1–1.6) and health worker (AOR: 1.2, 95% CI: 1.0–1.5). Experiencing violence at home (AOR: 0.25, 95% CI: 0.09–0.67) was associated with lower satisfaction. Following reported poor adherence and satisfaction with preventive measures, behavior change programs using health workers should be expanded throughout, with emphasis on men.Item Low proportion of women who came knowing their HIV status at first antenatal care visit, Uganda, 2012–2016: a descriptive analysis of surveillance data(BMC Pregnancy and Childbirth, 2020) Nakanwagi, Miriam; Bulage, Lilian; Kwesiga, Benon; Ario, Alex Riolexus; Agasha, Doreen Birungi; Lukabwe, Ivan; Matovu, John Bosco; Taasi, Geoffrey; Nabitaka, Linda; Mugerwa, Shaban; Musinguzi, JoshuaHIV testing is the cornerstone for HIV care and support services, including Prevention of Mother to Child Transmission of HIV (PMTCT). Knowledge of HIV status is associated with better reproductive health choices and outcomes for the infant’s HIV status. We analyzed trends in known current HIV status among pregnant women attending the first antenatal care (ANC) visit in Uganda, 2012–2016. We conducted secondary data analysis using District Health Information Software2 data on all pregnant women who came for ANC visit during 2012–2016. Women who brought documented HIV negative test result within the previous 4 weeks at the first ANC visit or an HIV positive test result and/or own HIV care card were considered as knowing their HIV status. We calculated proportions of women with known current HIV status at first ANC visit, and described linear trends both nationally and regionally. We tested statistical significance of the trend using modified Poisson regression with generalized linear models. For known HIV positive status, we only analyzed data for years 2015–2016 because this is when this data became available. There was no significant difference in the number of women that attended first ANC visits over years 2012 -2016. The proportion of women that came with known HIV status increased from 4.4% in 2012 to 6.9% in 2016 and this increase was statistically significant (p < 0.001). Most regions had an increase in trend except the West Nile and Mid-Eastern (p < 0.001). The proportion of women that came knowing their HIV positive status at first ANC visit was slightly higher than that of women that were newly tested HIV positive at first ANC visit in 2015 and 2016 Although the gap in women that come at first ANC visit without knowing their HIV positive status might be reducing, a large proportion of women who were infected with HIV did not know their status before the first ANC visit indicating a major public health gap. We recommend advocacy for early ANC attendance and hence timely HIV testing and innovations to promptly identify HIV positive women of reproductive age so that timely PMTCT interventions can be made.Item Multisectoral prioritization of zoonotic diseases in Uganda, 2017: A One Health perspective(PLoS ONE, 2017) Sekamatte, Musa; Krishnasamy, Vikram; Bulage, Lilian; Kihembo, Christine; Nantima, Noelina; Monje, Fred; Ndumu, Deo; Sentumbwe, Juliet; Mbolanyi, Betty; Aruho, Robert; Kaboyo, Winyi; Mutonga, David; Basler, Colin; Paige, Sarah; Behravesh, Casey BartonZoonotic diseases continue to be a public health burden globally. Uganda is especially vulnerable due to its location, biodiversity, and population. Given these concerns, the Ugandan government in collaboration with the Global Health Security Agenda conducted a One Health Zoonotic Disease Prioritization Workshop to identify zoonotic diseases of greatest national concern to the Ugandan government.Item Outbreak of Anthrax Associated with Handling and Eating Meat from a Cow, Uganda, 2018(Emerging Infectious Diseases, 2020) Kisaakye, Esther; Riolexus Ario, Alex; Bainomugisha, Kenneth; Cossaboom, Caitlin M. Ping Zhu; Lowe, David; Bulage, Lilian; Kadobera, Daniel; Sekamatte, Musa; Lubwama, Bernard; Tumusiime, Dan; Tusiime, Patrick; Downing, Robert; Buule, Joshua; Lutwama, Julius; Salzer, Johanna S.; Matkovic, Eduard; Joy Gary, Jana Ritter,; Zhu, Bao-PingOn April 20, 2018, the Kween District Health Office in Kween District, Uganda reported 7 suspected cases of human anthrax. A team from the Uganda Ministry of Health and partners investigated and identified 49 cases, 3 confirmed and 46 suspected; no deaths were reported. Multiple exposures from handling the carcass of a cow that had died suddenly were significantly associated with cutaneous anthrax, whereas eating meat from that cow was associated with gastrointestinal anthrax. Eating undercooked meat was significantly associated with gastrointestinal anthrax, but boiling the meat for >60 minutes was protective. We recommended providing postexposure antimicrobial prophylaxis for all exposed persons, vaccinating healthy livestock in the area, educating farmers to safely dispose of animal carcasses, and avoiding handling or eating meat from livestock that died of unknown causes.Item Risk perception and psychological state of healthcare workers in referral hospitals during the early phase of the COVID‑19 pandemic, Uganda(BMC psychology, 2021) Migisha, Richard; Riolexus, Alex A.; Kwesiga, Benon; Bulage, Lilian; Kadobera, Daniel; Kabwama, Steven N.; Katana, Elizabeth; Ndyabakira, Alex; Wadunde, Ignatius; Byaruhanga, Aggrey; Amanya, Geofrey; Harris, Julie R.; Fitzmaurice, Arthur G.Safeguarding the psychological well-being of healthcare workers (HCWs) is crucial to ensuring sustainability and quality of healthcare services. During the COVID-19 pandemic, HCWs may be subject to excessive mental stress. We assessed the risk perception and immediate psychological state of HCWs early in the pandemic in referral hospitals involved in the management of COVID-19 patients in Uganda. Methods: We conducted a cross-sectional survey in five referral hospitals from April 20–May 22, 2020. During this time, we distributed paper-based, self-administered questionnaires to all consenting HCWs on day shifts. The questionnaire included questions on socio-demographics, occupational behaviors, potential perceived risks, and psychological distress. We assessed risk perception towards COVID-19 using 27 concern statements with a four-point Likert scale. We defined psychological distress as a total score > 12 from the 12-item Goldberg’s General Health Questionnaire (GHQ-12). We used modified Poisson regression to identify factors associated with psychological distress. Results: Among 335 HCWs who received questionnaires, 328 (98%) responded. Respondents’ mean age was 36 (range 18–59) years; 172 (52%) were male. The median duration of professional experience was eight (range 1–35) years; 208 (63%) worked more than 40 h per week; 116 (35%) were nurses, 52 (14%) doctors, 30 (9%) clinical officers, and 86 (26%) support staff. One hundred and forty-four (44%) had a GHQ-12 score > 12. The most common concerns reported included fear of infection at the workplace (81%), stigma from colleagues (79%), lack of workplace support (63%), and inadequate availability of personal protective equipment (PPE) (56%). In multivariable analysis, moderate (adjusted prevalence ratio, [aPR] = 2.2, 95% confidence interval [CI] 1.2–4.0) and high (aPR = 3.8, 95% CI 2.0–7.0) risk perception towards COVID-19 (compared with low-risk perception) were associated with psychological distress. Conclusions: Forty-four percent of HCWs surveyed in hospitals treating COVID-19 patients during the early COVID- 19 epidemic in Uganda reported psychological distress related to fear of infection, stigma, and inadequate PPE. Higher perceived personal risk towards COVID-19 was associated with increased psychological distress. To optimizeItem Timing of onset of symptom for COVID-19 from publicly reported confirmed cases in Uganda(Pan African Medical Journal, 2021) Riolexus Ario, Alex; Basuta Mirembe, Bernadette; Biribawa, Claire; Bulage, Lilian; Kadobera, Daniel; Wamala, Robertincubation period for COVID-19, 2-14 (average 5-6) days. Timing of onset of COVID-19 signs and symptoms amongst cases in Uganda is however not known. Methods: we utilized data on real-time reverse transcription polymerase chain reaction (RT-PCR) confirmed cases to investigate symptom onset timing, from 21st March to 4th September 2020. Since timing of COVID-19 symptom onset is highly likely to be an interval rather than a point estimate, we generated 3-tertile categories: 1st, 2nd and 3rd tertile denoting symptom presentation within 3, 4 to 6 and at least 7 days. We considered all signs and symptoms in the database and analysed using Chi-square test and multinomial logistic regression, controlling for age and sex. Results: we analysed a total of 420 symptomatic case-patients; 72.0% were males, median age of 33 years. Common symptoms were cough (47.6%), running nose (46.2%), fever (27.4%), headache (26.4%) and sore throat (20.5%). We utilized 293 cases with clinical symptom onset date recorded. Most of the patients, 37.5%, presented symptom within 3 days, 31.4% had symptoms in the 2nd and 31.4% in 3rd tertile, denoting 4 to 6 days and at least 7 days after exposure. Running nose (RRR=0.45, 95%CI: 0.24-0.84) and chest pain (RRR=0.64, 95%CI: 0.09-0.72) were more likely to occur in 3rd tertile than 1st or 2nd tertile. Cases aged ≥20 years were less likely to have symptoms in the 1st and 2nd tertile compared to ≤20 years (p<0.05). Conclusion: our study provides empirical evidence for epidemiological characterization of cases by signs and symptoms which complements current proposals for the length of active monitoring of persons exposed to SARS-CoV-2.
