COVID-19 : comparison of the response in Rwanda, South Africa and Zimbabwe

The COVID-19 pandemic has had an impact worldwide with regions experiencing varying degrees of severity. African countries have mounted different response strategies eliciting varied outcomes. Here, we compare these response strategies in Rwanda, South Africa and Zimbabwe and discuss lessons that could be shared. In particular, Rwanda has a robust and coordinated national health system that has effectively contained the epidemic. South Africa has considerable testing capacity, which has been used productively in a national response largely funded by local resources but affected negatively by corruption. Zimbabwe has an effective point-of-entry approach that utilizes an innovative strategic information system. All three countries would benefi t having routine meetings to share experiences and lessons learned during the COVD-19 pandemic.http://mediccreview.orgam2022School of Health Systems and Public Health (SHSPH

Optimising COVID-19 vaccination policy to mitigate SARS-CoV-2 transmission within schools in Zimbabwe

The COVID-19 pandemic has disrupted the learning of millions of children across the world. Since March 2020 when the first cases of COVID-19 were reported in Zimbabwe, the country, like many others, has gone through periods of closing and re-opening of schools as part of the national COVID-19 control and mitigation measures. Schools promote the social, mental, physical, and moral development of children. With this viewpoint, the authors argue that schools should not be closed to provide a measured and efficient response to the threats posed by the COVID-19 epidemic. Rather, infection prevention and control strategies, including vaccination of learners and teachers, and surveillance in schools should be heightened. The use of multiple prevention strategies discussed in this viewpoint has shown that when outbreaks in school settings are adequately managed, the transmission usually is low. The information presented here suggests that schools should remain open due to the preponderance of evidence indicating the overriding positive impacts of this policy on the health, development, and wellbeing of children.https://www.mdpi.com/journal/vaccinesdm2022School of Health Systems and Public Health (SHSPH

Epidemiological surveillance of enteric viral diseases using wastewater in Africa – a rapid review

Viral enteric pathogens remain an important cause of diarrhoeal outbreaks among children in sub-Saharan Africa (SSA). Consequently, diarrhoeal illness remains a significant cause of morbidity and mortality in the under-fives in SSA. These outbreaks associated with viral pathogens tend to be seasonal and early warning systems for impending outbreaks could be very crucial for triggering preventive public health response and building public health resilience to deal with increased demand for medical services. Wastewater surveillance for pathogens is an important epidemiological component that could inform early warning systems. The objective of this rapid review was to evaluate the use of wastewater for epidemiology surveillance of enteric viral pathogens. Nine studies met the inclusion criteria. Eight viral pathogens were reviewed and analysed from 6 countries that performed wastewater analysis. Six studies explored the epidemiologic significance of viral pathogens in wastewater. The findings of this review revealed that monitoring of wastewater can provide an additional tool to determine the epidemiology of viral pathogens circulating in the community thereby providing early warning of potential outbreaks using wastewater-based epidemiology methods. Five of the included studies revealed the occurrence of viral pathogens in raw sewage and treated wastewater as an indication of inefficient elimination of viruses leading to potential release into water sources which presents a public health risk, increasing the risk of inducing gastroenteritis in the population. Six studies revealed the need for public health authorities to realise the potential benefit of environmental surveillance (ES) as an additional tool to determine the epidemiology of viral pathogens circulating in each community. Despite the significant public health challenge associated with enteric viral pathogens in sub-Saharan Africa, there remains remarkable underinvestment in potentially epidemiologically beneficial research, including wastewater-based epidemiology for these infections.http://www.elsevier.com/locate/jiphhj2023School of Health Systems and Public Health (SHSPH

Understanding the role of intimate partner violence on HIV transmission in Zimbabwe: Secondary data analysis of data from the Zimbabwe demographic survey 2015-2016

Background: Gender-based violence (GBV) has been shown to have significant and long-lasting impacts on women’s physical and mental health. It is, therefore, important to study its occurrence in a population and its intersect with infectious diseases such as HIV to inform the wider health promotion agenda. This study aimed to determine the association between GBV and HIV status in women and adolescent girls in Zimbabwe. Methods: A secondary data analysis of data from a cross-sectional Zimbabwe Demographic and Health Survey (ZDHS) was conducted. Statistical analysis was employed to establish the association between GBV and HIV status. Geospatial mapping was conducted using a kernel smoothing method was employed to generate a continuous kernel density surface to illustrate the local spatial variations of female HIV and GBV prevalence. Results: Women and adolescent girls suffering emotional GBV, such as those subjected to humiliation by their husbands or partners, were 1.45 (1.14-1.84) [OR (95% CIs)] times more likely to be HIV positive than those who were never humiliated. The same was true for women and adolescent girls whose husbands or partners threatened to harm them or someone they love, 1.33 (1.04-1.68). There is a relationship between women’s HIV status and intimate partner aggression, such as when their partners pushed, shook, or threw something at them or physically abused them. This was also the case for those who reported that partners kicked, dragged, or beat them, tried to choke or burn them on purpose, or threatened or attacked them with a knife, gun, or other weapons. Women who experienced forced sexual violence with threats were more likely 1.61 (1.08-2.41), to be HIV positive than those women who did not experience the same. Conclusion: GBV is widely spread in Zimbabwe. There is a need for the government to implement creative strategies to reach out to survivors, especially those that are forced to have unprotected sex and are at increased risk of HIV acquisition. This manuscript raises issues that can be addressed by robust health promotion strategies to reduce the impact of the syndemic of GBV and HIV acquisition in Zimbabwe

Increased illicit substance use among Zimbabwean adolescents and youths during the COVID-19 era: an impending public health disaster

Zimbabwe's illicit substance use problem has increased dramatically during the COVID-19 pandemic. Of particular concern has been the upward trend in drug/substance use among adolescents and youths. Commonly used substances in Zimbabwe include glue, bronclee, mangemba, cane sprit, marijuana, codeine and methamphetamine (crystal meth). In this letter, we discuss aggravated substance use during the COVID-19 pandemic in Zimbabwe, and how it is a serious impending public health disaster.http://wileyonlinelibrary.com/journal/addhj2021School of Health Systems and Public Health (SHSPH

Hesitancy, ignorance or uncertainty? The need for effective communication strategies as Zimbabwe’s uptake of COVID-19 vaccine booster doses remains poor

Zimbabwe started an ambitious COVID-19 vaccination programme in February 2021, aiming to vaccinate at least 60% of its eligible population by December 2021. The efforts to protect the population from the devastating effects of COVID-19 were remarkable, especially given that the country was not a part of the COVID-19 Vaccines Global Access (COVAX) initiative, and the government had to seek alternative sources of vaccines. The trajectory of COVID-19 vaccination in the country followed a very slow initial uptake from February to early June 2021. A sharp rise in demand and uptake followed between June and August 2021, coinciding with a harsh Delta variant-driven epidemic. However, as the situation stabilised and the cases plummeted, the uptake of the vaccines fell again, and by the beginning of December 2021, reports from the Ministry of Health and Child Care (MoHCC) of Zimbabwe show that the daily uptake had significantly gone down.https://www.sciencedirect.com/journal/public-health-in-practiceam2023School of Health Systems and Public Health (SHSPH

Towards equitable and sustainable availability of blood products in Zimbabwe : an analysis of strengths, weaknesses, opportunities and challenges

Blood transfusion can be a lifesaving intervention in a number of medical emergencies. To attain sustainable and equitable availability of blood products, it is important to understand the strengths, weaknesses, opportunities, and challenges of the national blood services programme. We, therefore, with this letter to the editor, discuss some of the strengths, weaknesses, opportunities and threats to the Zimbabwean programme since its inception. Despite several strengths and opportunities that the national blood services of Zimbabwe (NBSZ) leverages on, we argue that among other challenges, donor shortages and an upsurge of transfusion transmittable infections in the eligible donor population continue to be the biggest threats to the achievement of the programme objectives. These can be addressed through expanding the blood donor base and the catchment area. Additionally, improving the level of knowledge and attitude towards blood donation in the communities is critical for driving the sustainable and equitable distribution of safe blood products to the population.https://www.journals.elsevier.com/transfusion-clinique-et-biologique2023-08-17hj2022School of Health Systems and Public Health (SHSPH

Risk of mortality in HIV-infected COVID-19 patients : a systematic review and meta-analysis

BACKGROUND : The relationship between HIV infection and COVID-19 clinical outcomes remains a significant public health research problem. We aimed to determine the association of HIV comorbidity with COVID-19 mortality. METHODS : We searched PubMed, Google Scholar and World Health Organization library databases for relevant studies. All searches were conducted from 1st to 7th December 2021. Title, abstract and full text screening was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The relative risk of mortality in HIV-infected COVID-19 patients was computed using a random-effects model. All analyses were performed using Meta and Metasens statistical packages available in R version 4.2.1 software package. The quality of included studies was assessed using the GRADE approach, Egger’s test was employed to determine the risk of bias. RESULTS : A total of 16 studies were included in this review. Among the COVID-19 patients with HIV infection, the mortality rate due to COVID-19 was 7.97% (4 287/53,801), and among the COVID-19 patients without HIV infection, the mortality rate due to COVID-19 was 0.69% (127, 961/18, 513, 747). In the random effects model, we found no statistically significant relative risk of mortality in HIV-infected COVID-19 patients (RR 1.07, 95% CI 0.86–1.32). The between-studies heterogeneity was substantial (I2 = 91%, P < 0.01), while the risk of publication bias was not significant. CONCLUSION : Findings did not link HIV infection with an increased risk of COVID-19 mortality. Our results add to the conflicting data on the relationship between COVID-19 and HIV infection.http://www.elsevier.com/locate/jiphhj2022School of Health Systems and Public Health (SHSPH
