RESUMO
BACKGROUND: Malaria is a leading cause of morbidity and mortality among forcibly displaced populations, including refugees, approximately two-thirds of whom reside in malaria endemic regions. Data from the rapid disease notification system (RDNS) reports for Manicaland Province in Zimbabwe showed that despite implementation of malaria control initiatives, there was an increase in number of malaria cases above action thresholds at Tongogara refugee camp in Chipinge district during weeks 12-14 of 2021. An investigation that described the outbreak by person, place and time was conducted. Malaria emergency preparedness, response, and appropriateness of case management were assessed. The factors associated with contracting malaria were determined to enable the formulation of appropriate interventions, establish control, and prevent future malaria outbreaks among this vulnerable population. METHODS: A 1:1 unmatched case-control study involving 80 cases and 80 controls was conducted using interviewer-administered questionnaires at household level. Data was entered into Epi Data version 3.1 and quantitative analysis was done using Epi Info™ version 7.2.2.6 to generate medians, proportions, odds ratios and their 95% confidence intervals. RESULTS: Malaria cases were distributed throughout the 10 residential sections within Tongogara refugee camp, the majority being from section 7, 28 (35%). Despite constituting 11% of the total population, Mozambican nationals accounted for 36 (45%) cases. Males constituted 47 (59%) among cases which was comparable to controls 43 (54%), p = 0.524. The median age for cases was 15 years [Interquartile range (IQR), 9-26] comparable to controls, which was 17 years (IQR, 10-30) (p = 0.755). Several natural and man-made potential vector breeding sites were observed around the camp. Risk factors associated with contracting malaria were engaging in outdoor activities at night [AOR = 2.74 (95% CI 1.04-7.22), wearing clothes that do not cover the whole body during outdoor activities [AOR 4.26 (95% CI, 1.43-12.68)], while residing in a refugee housing unit reduced the risk of contracting malaria [AOR = 0.18 (CI, 0.06-0.55)]. CONCLUSIONS: The malaria outbreak at Tongogara refugee camp reemphasizes the role of behavioural factors in malaria transmission. Intensified health education to address human behaviours that expose residents to malaria, habitat modification, and larviciding to eliminate mosquito breeding sites were recommended.

BACKGROUND: Childhood tuberculosis (TB) is a major global public health concern contributing to significant child morbidity and mortality. A records review of the TB notification for Chegutu District Health Information System 2 (DHIS2) showed a low childhood TB case detection rate. For 2018 and 2019, childhood TB notifications were 4% and 7% respectively against the annual national childhood 12% case detection rate. We evaluated the performance of the childhood TB program in Chegutu. METHODS: We conducted a descriptive cross-sectional study. Sixty-six health workers (HW) participated in the study. Interviewer-administered questionnaires and checklists were used to collect data on reasons for low TB case detection, HW childhood TB knowledge, program inputs, processes, and outputs. Strengths, Weaknesses, Opportunities and Threats analysis was used to assess the childhood TB processes. We analyzed the data using Epi Info 7™ to generate frequencies, proportions and means. A Likert scale was used to assess health worker knowledge. RESULTS: The majority 51/66(77%) of HW were nurses and 51/66(67%) of respondents were females. Reasons for the low childhood TB case detection were lack of HW confidence in collecting gastric aspirates 55/66(83%) and HW's negative attitudes towards gastric aspirate collection 23/66(35%). HW 24/66 (37%) had a fair knowledge of childhood TB notification. The district had only one functional X-ray machine for 34 health facilities. Only 6/18 motorcycles were functional with inadequate fuel supply. No desk guide for the management of TB in children for HW (2018) was available in 34 health facilities. Ethambutol 400 mg was out of stock and adult 800 mg tablets were used. Funds allocated for motor vehicle and motorcycles service ($1612USD/year) were inadequate. The district failed to perform planned quarterly TB review meetings, contact tracing and childhood TB training due to funding and COVID-19 lockdown restrictions. CONCLUSION: The childhood TB program failed to meet its targets due to inadequate inputs, HW suboptimal knowledge and COVID-19 lockdown measures. Case detection and notification can be improved through on-job training, mentorship, support and supervision and adequate resources.

BACKGROUND: Anthrax continues to be a disease of public health importance in Zimbabwe, with sporadic outbreaks reported annually in many parts of the country. A human anthrax outbreak occurred in wards 22 and 23 of Makoni District from mid-June 2013 to end of January 2014, following cattle deaths in the wards. Laboratory tests confirmed anthrax as the cause for the cattle deaths. This study investigated the clinical characteristics, distribution of cases (places, person and time) and risk factors for contracting the anthrax disease. We also assessed the environment, district preparedness and response, and outbreak prevention and control measures. METHODS: We conducted an outbreak investigation using a mixed-methods design. A 1:1 case-control study was used to assess risk factors for contracting anthrax. The controls were frequency matched to cases by sex. Data were collected using a structured interviewer-administered questionnaire. Environmental assessment, district preparedness and response, and outbreak prevention and control measures were assessed using a checklist, observations, and key informant interviews. Multivariable unconditional logic regression analysis was performed to identify independent risk factors associated with contracting anthrax. RESULTS: We interviewed 37 of the 64 cases, along with 37 controls. All the cases had cutaneous anthrax, with the hand being the most common site of the eschar (43%). Most of the cases (89%) were managed according to the national guidelines. Multivariable analysis demonstrated that meat sourced from other villages [vs butchery, OR = 15.21, 95% CI (2.32-99.81)], skinning [OR = 4.32, 95% CI (1.25-14.94)], and belonging to religions that permit eating meat from cattle killed due to unknown causes or butchered after unobserved death [OR = 6.12, 95% CI (1.28-29.37)] were associated with contracting anthrax. The poor availability of resources in the district caused a delayed response to the outbreak. CONCLUSION: The described anthrax outbreak was caused due to contact with infected cattle meat. Although the outbreak was eventually controlled through cattle vaccination and health education and awareness campaigns, the response of the district office was initially delayed and insufficient. The district should strengthen its emergency preparedness and response capacity, revive zoonotic committees, conduct awareness campaigns and improve surveillance, especially during outbreak seasons.

BACKGROUND: Knowledge of HIV status remains a challenge despite implementation of various testing strategies including provider-initiated HIV testing (PITC). Harare City intensified provider-initiated HIV testing by targeting testing all eligible clients visiting facilities to achieve the UNAIDS first 95. This study aimed at evaluating the intervention to improve its effectiveness and inform programming decisions for universal access to HIV testing. METHODS: A descriptive cross-sectional study was conducted in Harare from April to June 2019. Evaluation of the intervention was conducted using the logic model approach to assess the inputs, processes and outputs. Health workers were interviewed using an interviewer administered questionnaire. Exit interviews were conducted for eligible clients > 18 years who refused to be tested. A checklist was used to assess the inputs used and a desk review of HIV screening and testing records was done. RESULTS: A total of (n-45) health care workers and (n = 70) clients were interviewed with a response rate of (92%) and (84%) respectively. The median age for clients was 31(Q1 = 24: Q3 = 38) and median years in service for health workers was 2 (Q1 = 1;Q3 = 26). Of the 133,899 clients who were eligible for testing after screening, 98,587 (74%) accepted the test leaving a gap of 35,312 (26%). However, 21/45 (47%) of health workers indicated high workload in the morning as the major reason for the leakage. In addition, 25/70 (36%) of the clients indicated long waiting time as the reason for opting out of HIV testing. CONCLUSION AND RECOMMENDATION: HIV testing coverage for eligible clients was not optimal, 26% opted out. We recommend strengthening of health facility systems such as review of patient flow, re-allocation of staff during busy HIV testing time and scaling up the use of HIV self-test kits for clients concerned with waiting time to improve HIV testing coverage.

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.

BACKGROUND: Maternal Death Surveillance and Response (MDSR) system was established to provide information that effectively guides actions to eliminate preventable maternal mortality. In 2016, Hwange district sent six maternal death notification forms (MDNF) to the province without maternal death audit reports. Timeliness of MDNF reaching the province is a challenge. Two MDNF for deaths that occurred in February and May 2016 only reached the provincial office in September 2016 meaning the MDNF were seven and four months late respectively. We evaluated the MDSR system in Hwange district. METHODS: A descriptive cross-sectional study was conducted. Health workers in the sampled facilities were interviewed using questionnaires. Resource availability was assessed through checklists. Epi Info 7 was used to calculate frequencies, means and proportions. RESULTS: We recruited 36 respondents from 11 facilities, 72.2% were females. Inadequate health worker knowledge, lack of induction on MDSR, unavailability of guidelines and notification forms and lack of knowledge on the flow of information in the system were reasons for late notification of maternal deaths. Workers trained in MDSR were 83.8%. Only 36.1% of respondents had completed an MDNF before. Respondents who used MDSR data at their level were 91.7%, and they reported that MDSR system was useful. Responsibility to complete the MDNF was placed on health workers. Maternal death case definitions were available in 2/11 facilities, 4/11 facilities had guidelines for maternal death audits. It costs $60.78 to notify a maternal death. CONCLUSION: Reasons for late notification of maternal deaths were inadequate knowledge, lack of induction, unavailability of guidelines and notification forms at facilities. The MDSR system is useful, acceptable, flexible, unstable, reliable but not simple. Maternal case definitions and maternal death audit guidelines should be distributed to all facilities. Training of all health workers involved in MDSR is recommended.

BACKGROUND: Visual inspection with acetic acid and cervicography (VIAC) is a method used to screen for cervical cancer. VIAC can be used as part of a "see and treat" strategy. Nine Harare city council health facilities offer VIAC free of charge with the aim of reducing morbidity and mortality from cervical cancer. Between 2014 and 2016, the number of women utilising VIAC dropped by 35%. We analysed records of clients who utilise VIAC at Harare city health facilities to characterise women accessing VIAC and their outcomes to make recommendations for improving the services. METHODS: We conducted a descriptive cross-sectional study using data collected for the Harare city VIAC program. We analysed all records of clients who utilised VIAC services at nine Harare city health facilities from 1 May 2012 to 31 December 2016. RESULTS: We analysed 46,217 records, the median age of the clients was 34 years [Q1 = 27: Q3 = 42]. Of the 46,217 clients screened, 3001 (6.5%) were VIAC positive, and 512 (1.1%) had suspicious of cancer lesions. The prevalence of VIAC positive ranged from 58 to 74 per 1000-screened clients over the 5 years. The prevalence of suspected cancer ranged from 9 to 14 per 1000-screened clients, and there was a general decrease in the prevalence between 2012 and 2016. Of the 3513 clients with VIAC positive or had suspicious of cancer lesions, 2090 (74.1%) did not receive treatment at the site where the screening took place. CONCLUSION: The majority of women who are accessing VIAC services in Harare are middle-aged, multiparous and married women. There is a treatment gap at most of the VIAC centres such that clients are referred to other centres for management. The objective of "see and treat" is not being realised.

Sexual violence is a major public health problem due to the associated risk of acquiring sexually transmitted infections, behavioural disorders and risk of committing suicide. The Adult Rape Clinic (ARC) was established at Parirenyatwa Hospital, Harare in 2009 with the objective of providing medical and support services for survivors of sexual violence in a safe and private environment. The data collected had never been analysed since the establishment of the clinic. We described the clients' profile and the services offered at the clinic to identify gaps in service provision and areas of improvement. A retrospective record review of data was carried out from the ARC collected from February 2009 to December 2017. We analyzed 2343 affidavits that were available. Out of 2343 records analysed, (2190) 93.5% were female and 6.5 % (153) were male. The median age was 23years (Q1=21; Q3= 29) for males and 19 years (Q1= 17; Q2=25) for females. Among the clients, 2164 (92.4%) received a baseline HIV test, and 263 females and 6 males tested positive. From 2010 to 2017, six clients' seroconversion was recorded. Only 863(36.8%) clients presented within 3 days after the sexual assault. About 40% of male victims were assaulted by someone they knew and 27% were married. The study recommends further research on the determinants of late presentation after sexual assault.

BACKGROUND: Zimbabwe is on track towards achieving viral suppression among adults (87%). However, adolescents have only achieved 44% by 2016. In Harare city, 57% of adolescents had attained viral suppression after 12 months on ART compared to 88% among adults. We determined factors associated with virological failure among adolescents (age 10-19 years) on antiretroviral therapy (ART) in Harare city. METHODS: We conducted a one to one unmatched case control study among 102 randomly recruited case: control pairs at the two main infectious disease hospitals in Harare. A case was any adolescent who presented with VL > 1000c/ml after at least 12 months on ART. A control was any adolescent who presented with VL < 1000c/ml after at least 12 months on ART. Interviewer administered questionnaires were used to collect data. Epi Info 7 was used to generate frequencies, means, proportions, ORs and p-values at 95% CI. RESULTS: We interviewed 102 case-control pairs. Poor adherence to ART [aOR = 8.15, 95% CI (2.80-11.70)], taking alcohol [aOR = 8.46, 95% CI (3.22-22.22)] and non- disclosure of HIV status [aOR = 4.56, 95% CI (2.20-9.46)] were independent risk factors for virological failure. Always using a condom [aOR = 0.04, 95% CI (0.01-0.35)], being on second line treatment [aOR = 0.04, 95% CI (0.23-0.81)] and belonging to a support group [aOR = 0.41, 95% CI (0.21-0.80)] were protective. CONCLUSION: Poor adherence, alcohol consumption and non-disclosure increased the odds of virological failure. Based on these findings support should focus on behavior change and strengthening of peer to peer projects to help address issues related to disclosure and adherence. Further operational research should aim to define other components of effective adherence support for adolescents with virological failure.

BACKGROUND: Despite the guidelines for managing sexual assault being in place, victims of sexual assault attended to at Kadoma General Hospital consistently raised complaints related to the quality of care offered. Medicolegal data for sexual assault has been collected at the hospital since 2012. However, no analysis had been done regardless of complaints having been raised. We analysed the dataset to determine the quality of clinical care offered to sexual assault victims. METHODS: A retrospective cross-sectional study based on secondary data was conducted. Epi. Info 7 software was used to analyse data and generate frequencies, measures of central tendency and proportions. RESULTS: We analysed 474 medical affidavits completed between January 2014 and July 2016. Thirty percent of the victims sought care within 72 h of the sexual assault. Baseline HIV testing was done in 23 (22%) and follow-up HIV test done in 2 (2%) of the victims. Post Exposure Prophylaxis for HIV was administered to 18 (51%), emergency contraception 9 (69%) and forensic evidence gathered in six (5%) of victims presenting within the prescribed 72 h of the sexual assault. Prophylactic antibiotics were given to 156 (33%). There were no documented counselling sessions for all victims whilst follow up care was given to 47 (10%) victims. CONCLUSION: Suboptimal clinical care was given to victims of sexual assault during the period 2014-2016. These findings suggest possible delayed presentation by victims of sexual assault as well as suboptimal administration of prophylaxis by health care workers. We recommend adherence to guidelines in managing sexual assault. Further research to determine factors for delayed presentation among sexual assault victims and quality of care provided to them is recommended.

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.

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.

BACKGROUND: Globally, non-attendance for immunization appointments remains a challenge to healthcare providers. A review of the 2011 immunization coverage for Kadoma City, Zimbabwe was 74% for Oral Polio Vaccine (OPV), Pneumococcal and Pentavalent antigens. The immunization coverage was less than 90%, which is the target for Kadoma City. Adoption of short message services (SMS) reminders has been shown to enhance attendance in some medical settings. The study was conducted to determine the effectiveness of SMS reminders on immunization programme for Kadoma City. METHODS: A randomized controlled trial was conducted at Kadoma City clinics in Zimbabwe. Women who delivered and were residents of Kadoma City were recruited into the study. In the intervention group, SMS reminders were sent at 6, 10 and 14 weeks in addition to routine health education. In the non-intervention no SMS reminders were used, however routine health education was offered. Data were collected using interviewer administered questionnaire. Data were analyzed using Epi Info 7™, where frequencies, means, risk ratios and risk differences were generated. RESULTS: A total of 304 participants were recruited, 152 for the intervention group and 152 for the non-intervention group. The immunization coverage at 6 weeks was 97% in the intervention group and 82% in the non-intervention group (p < 0.001). At 14 weeks immunization coverage was 95% for intervention and 75% for non-intervention group (p < 0.001). Those who did not delay receiving immunization at 14 weeks was 82% for the intervention and 8% for non-intervention group. Median delay for intervention was 0 days (Q1 = 0; Q3 = 0) and 10 days (Q1 = 6; Q3 = 17) for non-intervention group. The risk difference (RD) for those who received SMS reminders than those in the non intervention group was 16.3% (95% CI: 12.5-28.0) at 14 weeks. CONCLUSION: Immunization coverage in the intervention group was significantly higher than in non-intervention group. Overall increase in immunization coverage can be attributed to use of SMS. TRIAL REGISTRATION: ISRCTN70918594 . Registration Date: 28 August 2014.

BACKGROUND: From 2005 to 2011 Mazowe District recorded a gradual decline in prevalence of hypertension in the face of rising incidence of complications like stroke. This raised questions on whether diagnosis and management of hypertensive patients is being done properly. METHODS: We conducted an analytic cross sectional study at three hospitals in Mazowe District where we randomly selected 201 of 222 patients from out patients departments and interviewed a convenience sample of 23 healthcare workers. Structured interviewer administered questionnaires were used to collect data on demographic characteristics and knowledge from patients, as well as knowledge and practices from health workers. Physical measurements were done on all patients. Frequencies; proportions, odds ratios, Chi square test and stratified & logistic regression analysis were done using Epi info version 3.5.4 while graphs were generated using Microsoft excel®. Calculations were done at 95% confidence interval. RESULTS: Prevalence, awareness, control, compliance, and complication rate of hypertension were: 69.7%, 56.2%, 22.0%, 59.8% and 20.7% respectively. Independent risk factors for hypertension were age (POR 3.09; 95% CI: 1.27-7.5), obesity (POR 4.37; 95% CI: 1.83-10.4), and previous high blood pressure reading (POR 19.86; 95% CI: 8.61-45.8). Complications included cardiac failure (8.6%), visual defects (4.3%) and stroke (3.6%). Co-morbid human immunodeficiency virus (10.7%) and diabetes mellitus (12.1%) were identified among respondents. Knowledge was poor in 47.7% of health workers. CONCLUSIONS: Risk factors found in this study are consistent with other studies. Health service factors are the main reasons for poor diagnosis and management of hypertension. Health workers need training on diagnosis and management of hypertension. Guidelines, digital sphygmomanometers and adequate drug supply are needed. District has since purchased digital BP machines and requested assistance with training on clinical features of hypertension, use of digital machines, and how to properly measure BP. A policy document on non-communicable diseases including hypertension was subsequently developed by the Ministry of Health and Child Care and currently awaiting endorsement by parliament.

BACKGROUND: Maternal mortality is of global concern, almost 800 women die every day due to maternal complications. The maternal death surveillance and response (MDSR) system is one strategy designed to reduce maternal mortality. In 2021 Makonde District reported a maternal mortality ratio of 275 per 100 000 and only sixty-two percent of deaths recorded were audited. We evaluated the MDSR system in Makonde to assess its performance. METHODS: A descriptive cross-sectional study was conducted using the CDC guidelines for evaluating public health surveillance systems. An Interviewer-administered questionnaire was used to collect data from 79 health workers involved in MDSR and healthcare facilities. All maternal death notification forms, weekly disease surveillance forms, and facility monthly summary forms were reviewed. We assessed health workers' knowledge, usefulness and system attributes. RESULTS: We interviewed 79 health workers out of 211 workers involved in MDSR and 71 (89.9%) were nurses. The median years in service was 8 (IQR: 4-12). Overall health worker knowledge (77.2%) was good. Ninety-three percent of the deaths audited were of avoidable causes. Twelve out of the thirty-eight (31.6%) facilities were using electronic health records system. Feedback and documented shared information were evident at four facilities (21%) including the referral hospital. Nineteen (67.9%) out of 28 maternal death notification forms were completed within seven days and none were submitted to the PMD on time. CONCLUSION: The MDSR system was acceptable and simple but not timely, stable and complete. Underutilization of the electronic health system, work load, poor documentation and data management impeded performance of the system. We recommended appointment of an MDSR focal person, sharing audit minutes and improved data management.

BACKGROUND: Kadoma City experienced an increase in watery diarrhoea from 27 cases during week beginning 5th September, to 107 cases during week beginning 26th September 2011. The weekly diarrhoea cases crossed the threshold action line during week beginning 5th September at the children's clinic in Rimuka Township, and the remaining four clinics reported cases crossing threshold action lines between week beginning 12th September and week beginning 26th September. Eighty-two percent of the cases were children less than 5 years old. We conducted a case controlstudy to determine risk factorsfor contracting watery diarrhoea in children less than 5 years in Kadoma City. METHODS: An unmatched 1:1 case control study was conducted in Ngezi and Rimuka townships in Kadoma City, Zimbabwe. A case was a child less than 5 years old, who developed acute watery diarrhoea between 5th September and 1st October 2011. A control was a child less than 5 years old who stayed in the same township and did not suffer from diarrhoea. A structured questionnaire was administered to caregivers of cases and controls.Laboratory water quality tests and stool test results were reviewed.Epi Info™ statistical software was used to analyse data. RESULTS: A total of 109 cases and 109 controls were enrolled. Independent protective factors were: having been exclusively breastfed for six months [AOR = 0.44; 95% CI (0.24-0.82)]; using municipal water [AOR = 0.38; 95% CI (0.18-0.80)]; using aqua tablets, [AOR = 0.49; 95% CI (0.26-0.94)] and; storing water in closed containers, [AOR = 0.24; 95% CI (0.07-0.0.83). The only independent risk factor for contracting watery diarrhoea was hand washing in a single bowl, [AOR = 2.89; 95% CI (1.33-6.28)]. Salmonella, Shigella, Rotavirus, and Enteropathogenic Escherichia coli were isolated in the stool specimens. None of the 33 municipal water samples tested showed contamination with Escherichia coli, whilst 23 of 44 (52%) shallow well water samples and 3 of 15(20%) borehole water samples tested were positive for Escherichia coli. CONCLUSIONS: The outbreak resulted from inadequate clean water and use of contaminated water. Evidence from this study was used to guide public health response to the outbreak.

BACKGROUND: Zimbabwe is one of the five countries worst affected by the HIV/AIDS pandemic with HIV infection contributing increasingly to childhood morbidity and mortality. Among the children born to HIV positive mothers participating in the PMTCT programme, 25% tested positive to HIV. We investigated factors associated with HIV infection among children born to mothers on the PMTCT programme. METHODS: A 1:1 unmatched case-control study was conducted at Chitungwiza Hospital, Zimbabwe, 2008. A case was defined as a child who tested HIV positive, born to a mother who had been on PMTCT programme. A control was a HIV negative child born to a mother who had been on PMTCT programme. An interviewer-administered questionnaire was used to collect data on demographic characteristics, risk factors associated with HIV infection and immunization status. RESULTS: A total of 120 mothers were interviewed. Independent risk factors associated with HIV infection among children included maternal CD4 count of less than 200 during pregnancy [aOR = 7.1, 95% CI (2.6-17)], mixed feeding [aOR = 29, 95% CI (4.2-208)], being hospitalized since birth [aOR = 2.9, 95% CI (1.2-4.8)] whilst being exclusively breast fed for less than 6 months [aOR = 0.1 (95% CI 0.03-0.4)] was protective. CONCLUSIONS: HIV infection among children increased if the mother's CD4 count was ≤200 cells/µL and if the child was exposed to mixed feeding. Breastfeeding exclusively for less than six months was protective. We recommended exclusive breast feeding period for the first six months and stop breast feeding after 6 months if affordable, sustainable and safe.

Introduction: preventing COVID-19 infection among health workers maintains the health system capacity and reduces secondary transmission. Of 506 health workers tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Harare City between December 2020 and February 2021 (second wave), 128 (25%) tested positive, affecting service delivery. We investigated factors associated with COVID-19 infection and described breakthrough infections among health workers. Methods: we conducted a cross-sectional study in Harare City. Interviews were conducted with 467 health workers to determine behavioral, occupational, and non-occupational factors associated with COVID-19 infection. Fifteen key informants were interviewed to verify responses. Records and line-list were reviewed to verify cases, outcomes, and vaccination status. Observations were done to check adherence to prevention measures. Epi-info generated means, frequencies, proportions and conducted univariate, bivariate and multivariate analysis. Statistical significance was at p-value<0.05. Results: we interviewed 467 health workers, 166 (35.5%) had a history of COVID-19 infection. Females were the majority 357 (76.4%), mostly nurses 200 (42.8%). Those not trained on infection control measures in the past six months (aOR=2.13; 95%CI 1.06-4.27; p=0.03), not observing social distance at mealtimes (aOR=6.33; 95%CI 3.36-11.89; p<0.01), having a household COVID-19 case (aOR=9.03; 95%CI 3.93-20.76; p<0.01) and not properly wearing facemasks (aOR=16.68; 95%CI 9.39-29.61; p<0.01) were significantly associated COVID-19 infection. Of 378 health workers fully vaccinated, 39 (10.3%) had breakthrough infections. Most with breakthrough infections, 33 (84.6%) had asymptomatic or mild disease. One death was recorded, a female, not vaccinated, with uncontrolled diabetes. Conclusion: predictors of COVID-19 infection among health workers were, no training on infection and prevention and control (IPC) measures, lack of social distancing at mealtimes, improper use of facemasks, and having a COVID-19 case at household level. We conducted refresher training to strengthen infection control measures.

INTRODUCTION: Globally people with tuberculosis (TB) continue to be missed each year. They are either not diagnosed or not reported which indicates possible leakages in the TB care cascade. Zimbabwe is not spared with over 12000 missed cases in 2020. A preliminary review of TB treatment outcomes indicated patient leakages throughout the presumptive cascade and undesirable treatment outcomes in selected cities. Chegutu District had pre-diagnosis and pretreatment losses to follow-up while Mutare City among others had 22.0% of outcomes not evaluated in the second quarter of 2021, and death rates as high as 14% were recorded in Gweru District. The problem persists despite training on data analysis and use. The TB cohorts were analysed to determine the performance of the care cascade and the spatial distribution of treatment outcomes in Zimbabwe. METHODS: Using data from district health information software version 2.3 (DHIS2.3), a secondary data analysis of 2020 drug-sensitive (DS) TB treatment cohorts was conducted. We calculated the percentage of pre-diagnosis, and pre-treatment loss to follow-up (LTFU). For TB treatment outcomes, 'cured' and 'treatment completed' were categorized as treatment success, while 'death', 'loss to follow-up (LTFU), and 'not evaluated' were categorized as undesirable outcomes. Univariate analysis of the data was conducted where frequencies were calculated, and data was presented in graphs for the cascade, treatment success, and undesirable outcomes while tables were created for the description of study participants and data quality. QGIS was used to generate maps showing undesirable treatment outcomes. RESULTS: An analysis of national data found 107583 people were presumed to have TB based on symptomatic screening and or x-ray and 21.4% were LTFU before the specimen was investigated. Of the 84534 that got tested, 10.0% did not receive their results. The treatment initiation rate was 99.1%. Analysis of treatment outcomes done at the provincial level showed that Matabeleland South Province had the lowest treatment success rate of 77.3% and high death rates were recorded in Matabeleland South (30.0%), Masvingo (27.3%), and Matabeleland North (26.1%) provinces. Overall, there were high percentages of not-evaluated treatment outcomes. CONCLUSION: Pre-diagnosis LTFU was high, and high death and loss to follow-up rates were prevalent in provinces with artisanal and small-scale mining (ASM) activities. Unevaluated treatment outcomes were also prevalent and data quality remains a challenge within the national TB control program. We recommended strengthening patient follow-up at all levels within the TB care cascade, strengthening capacity-building for data analysis and use, further analysis to determine factors associated with undesirable outcomes and a study on why LTFU remains high.

Introduction: approximately 15% of COVID-19 patients develop symptoms necessitating admission. From 2020 to 2022, Mashonaland West Province had an institutional case fatality rate of 23% against a national rate of 7%. Therefore, we evaluated the COVID-19 admissions in the province to determine the factors associated with COVID-19 mortality. Methods: we conducted an analytical cross-sectional study based on secondary data from isolation centers across the province using all 672 death audit forms and patient records. We obtained data on patient demographics, signs and symptoms, clinical management and oxygen therapy administered, among other things. Data were entered into an electronic form and imported into Epi-info 7 for analysis bivariate and multivariate conducted. Results: we found that being an older man, aOR 1.04 (1.03-1.05), who had diabetes aOR 6.0 (95% CI: 3.8-9.2) and hypertension aOR 4.5 (95% CI: 2.8-6.5) were independent risk factors. Patients put on dexamethasone aOR 2.4 (95% CI: 1.6-3.4) and heparin/clexane aOR 1.6 (95% CI: 1.1-2.2) had a higher mortality risk. However, vitamin C aOR 0.48 (95% CI: 0.31-0.71) and oxygen therapy aOR 0.14 (95% CI: 0.10-0.19) and being pregnant aOR 0.06 (95% CI: 0.02-0.14) were protective. Conclusion: mortality risk increased in older male patients with comorbidities and with those on dexamethasone and heparin therapy. Oxygen therapy and vitamin C were protective. There is a need to conduct further study of the source of these variations in risk across patients to establish the true impact of differences in individuals' mortality.
