Abstract	Background: Zimbabwe’s Index Testing programme has failed to achieve targets since its inception in 2017. We determined the index testing implementation modalities to identify and recommend effective contact elicitation, tracking and testing modalities to enhance positivity yield. Subjects dan Method: This study conducted a cross-sectional study on 50 multistage selected health facilities. Dependent variables were all clients, (≥15 years) diagnosed with HIV in 2021, whilst independent variables were contact tracking. The study instrument of variable measure was cascade analysis to identify tracing modalities against yield. Quantitative data were summarized as proportions, odds ratios, and adjusted odds ratios at a 5% significance level. Results: Of 6,308 index cases identified, females constituted 53.9% (n=3,401 and 67.6% (n=4,265) were retests. Index testing was offered to 66.4% (n=4,190), accepted by 93.1% (n=3,899) and the elicitation rate was 1:1.3 (n=5,080). A positivity yield of 27.5% (n=1,736) was achieved from 78.6% (n= 3,991) contacts. Mixed method tracking yielded 46.7% (n=349) positivity from a testing rate of 99.5% (n=748) in an urban setup, with 41.4% (n=1,243) preferring health worker referrals. As high as 202 contacts were not tested following elicitation through client referrals. In a rural setup, client referrals accounted for 53.1%, (n=1,103) yet 122 of these were not tested. The highest positivity yield was obtained from health worker referrals at 65.6% (n=196). Being male (aOR=3.09; 95%CI= 2.74 to 3.49), first tester (aOR=1.65; 95%CI= 1.43 to 1.91), anonymous tracking (aOR=8.46; 95%CI:3.37 to 22.75) and testing contacts within 7 days of elicitation (aOR=2.78; 95%CI=2.44 to 3.18) were identified as high predictors of positivity yield among index contacts. Conclusion: The identified high positivity yield among men, first-time testers and contacts tested within 7 days of elicitation may inform index testing focussing to improve program performance. Implementation fidelity and differentiated ...

Abstract	Abstract 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 ...

Abstract	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 ...

Abstract	HIV positivity yield declined against increasing testing volumes in Zimbabwe, from 20% (1.65 million tests) in 2011 to 6% (3 million tests) in 2018. A screening tool was introduced to aid testers to identify clients likely to obtain a positive diagnosis of HIV. Consequently, testing volumes declined to 2.3 million in 2019 but positivity declined to 5% prompting the evaluation and validation of the tool to improve its precision in predicting positivity yield. A cross-sectional study was conducted. Sixty-four sites were randomly selected where all reporting clients (18+ years) were screened and tested for HIV. Participant responses and test outcomes were documented and uploaded to excel. Multivariable analysis was used to determine the performance of individual, combination questions and screening criteria to achieve >/ = 90% sensitivity for a new screening tool. We evaluated 13 questions among 7,825 participants and obtained 95.7% overall sensitivity, ranging from 3.9% [(95%CI:2.5,5.9) sharing sharp objects] to 86.8% [(95%CI:83.8,89.5) self-perception of risk] for individual questions. A 5-question tool was developed and validated among 2,116 participants. The best combination (self-perception of risk, partner tested positive, history of ill health, last tested >/ = 3months and symptoms of an STI) scored 94.1% (95%CI:89.4,97.1) sensitivity, 18% reduction in testing volumes and 11 Number Needed to Test (NNT). A screening in criteria that combine previously testing >/ = 3 months with a yes to any of the 4 remaining questions was analysed and sensitivity ranged from 89.9% (95%CI:84.4,94.0) for last tested >/ = 3months and sexual partner positive, to 93.5% (95%CI:88.7,96.7) for last tested >/ = 3months and self-perceived risk We successfully developed, evaluated and validated an HIV screening tool. High sensitivity and the fifth reduction in testing volume were acceptable attributes to enhance testing efficiency and effective limited resource utilisation. Screened out clients will be identified through ...

Abstract	Abstract 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 ...

Abstract	Abstract 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 ...

Abstract	Abstract 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.

Abstract	Abstract Objectives Poliomyelitis is an infectious disease caused by the polio virus which affects mostly young children below the age of 15 years. For surveillance children with acute flaccid paralysis (AFP) are tracked. In Zimbabwe every district should report two cases per 100,000 population of children under the age of 15 years old. In 2017, Mwenezi district failed to detect any AFP cases. We therefore evaluated the AFP surveillance system in Mwenezi district. We conducted a surveillance system evaluation using the updated Centers for Disease Control guidelines for evaluating public health surveillance systems. We interviewed health workers in Mwenezi district and looked at AFP records from January to December 2017. Results The main reasons for failure to report a case in 2017 were the vastness of the district with bad road networks as well as lack of a dedicated vehicle to carry out EPI outreach activities. About a quarter, 24%, of the health workers did not know the specimen that is used in AFP diagnosis. The AFP surveillance system in Mwenezi district was performing poorly due to lack of active search of cases in the community caused by disruption of EPI outreach activities.
