Abstract
The global emergence of coronavirus disease 2019 (COVID-19) posed unprecedented challenges, jeopardizing decades of progress in healthcare systems, education, and poverty eradication. While proven interventions such as handwashing and mass vaccination offer effective means of curbing COVID-19 spread, their uptake remains low, potentially undermining future pandemic control efforts. This systematic review synthesized available evidence of the factors influencing vaccine uptake and handwashing practices in Kenya, Uganda, and Tanzania in the context of COVID-19 prevention and control. We conducted an extensive literature search across PubMed, Science Direct, and Google Scholar databases following Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Out of 391 reviewed articles, 18 were eligible for inclusion. Some of the common barriers to handwashing in Kenya, Uganda, and Tanzania included lack of trust in the government's recommendations or messaging on the benefits of hand hygiene and lack of access to water, while some of the barriers to vaccine uptake included vaccine safety and efficacy concerns and inadequate awareness of vaccination sites and vaccine types. Enablers of handwashing practices encompassed hand hygiene programs and access to soap and water while those of COVID-19 vaccine uptake included improved access to vaccine knowledge and, socio-economic factors like a higher level of education. This review underscores the pivotal role of addressing these barriers while capitalizing on enablers to promote vaccination and handwashing practices. Stakeholders should employ awareness campaigns and community engagement, ensure vaccine and hygiene resources' accessibility, and leverage socio-economic incentives for effective COVID-19 prevention and control.

PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0002678. [PMID: 38051721 PMCID: PMC10697532 DOI: 10.1371/journal.pgph.0002678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 11/08/2023] [Indexed: 12/07/2023]
Abstract
The ability of a health system to withstand shocks such as a pandemic depends largely on the availability and preparedness of health-care workers (HCWs), who are at the frontline of disease management and prevention. Despite the heavy burden placed on HCWs during the COVID-19 pandemic, little is known regarding their experiences in low-income countries. We conducted a web-based survey with HCWs in randomly selected districts of Tanzania to explore their experiences with COVID-19-related prevention and control measures. The survey assessed implementation of COVID-19 control guidelines in health facilities, HCW perceptions of safety, well-being and ability to provide COVID-19 care, and challenges faced by frontline workers during the pandemic. We used multivariate regression analysis to examine the association between HCW and health facility characteristics, a score of guideline implementation, and challenges faced by HCWs. 6,884 Tanzanian HCWs participated in the survey between December 2021 to March 2022. The majority of respondents were aware of the COVID-19 guidelines and reported implementing preventive measures, including masking of both HCWs and patients. However, HCWs faced several challenges during the pandemic, including increased stress, concerns about infection, and inadequate personal protective equipment. In particular, female HCWs were more likely to report exhaustion from wearing protective equipment and emotional distress, while physicians were more likely to experience all challenges. While most HCWs reported feeling supported by facility management, they also reported that their concerns about COVID-19 treatment were not fully addressed. Notably, perceptions of protection and well-being varied widely among different HCW cadres, highlighting the need for targeted interventions based on level of exposure. In addition, various factors such as HCW cadre, facility ownership and COVID-19 designation status influenced HCWs' opinions about the health system's response to COVID-19. These findings highlight the importance of consistent implementation of guidelines and social and emotional support for HCWs.

Levels of handwashing and vaccine uptake in Kenya, Uganda, and Tanzania to prevent and control COVID-19: a systematic review and meta-analysis. Front Public Health 2023; 11:1256007. [PMID: 38026286 PMCID: PMC10666047 DOI: 10.3389/fpubh.2023.1256007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 10/27/2023] [Indexed: 12/01/2023] Open
Abstract
Introduction Coronavirus Disease 2019 (COVID-19) presents a massive challenge in Africa due to overwhelmed and underresourced health systems, as well as the existing burden of communicable and non- communicable diseases. Self-inoculation may occur when an individual touches their mucous membrane following direct contact between their hands and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)-contaminated surfaces. Therefore, handwashing can be used along with COVID-19 vaccines to reduce the spread of SARS-CoV-2 and the burden of COVID-19. We were interested in investigating the levels of handwashing and vaccine uptake to control and prevent COVID-19 in Kenya, Uganda and Tanzania using a systematic review and meta-analysis. Methods We searched PubMed, African Index Medicus and African Journals Online for studies published since inception to 31st January 2023. We included all studies that assessed: the levels of COVID-19 vaccine acceptance and hesitance as indicators of vaccine uptake; and studies on the levels of handwashing to prevent and control COVID-19 in Kenya, Uganda and Tanzania. Study findings were synthesized by meta-analysis to get the pooled effect measure. Three studies were synthesized qualitatively due to high level of heterogeneity in effect measure precluding a quantitative meta-analysis. Results Our search identified 128 articles of which 17 studies with 18,305 participants and 622 vaccination sites were reviewed with 14 of them being meta-analyzed. This systematic review and meta-analysis reports high levels of COVID-19 vaccine acceptance and handwashing in Kenya, Uganda and Tanzania at 67% (95% CI: 55, 78) and 88% (95% CI: 73, 97), respectively. Vaccine hesitance among the participants was low at 31% (95% CI: 15, 49). Discussion Despite their importance in the control and prevention of COVID-19, some countries do not implement handwashing and vaccination effectively. There is a need for public health strategies to raise awareness about the importance of handwashing and the uptake of the COVID-19 vaccine.

The role of trust in the implementation and uptake of COVID-19 response measures: a qualitative study of health professionals' experiences in Tanzania. BMC Health Serv Res 2023; 23:1077. [PMID: 37817175 PMCID: PMC10566036 DOI: 10.1186/s12913-023-10043-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 09/17/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND Even though trust is placed at the central point in ensuring proper functioning of the health systems, studies remain scant on how it affects both the implementation and uptake of COVID-19 response measures in low- and middle-income countries such as Tanzania. This study, therefore, explored the role of trust in the implementation and uptake of recommended COVID-19 response measures including vaccines from the perspective of health professionals in Tanzania. METHODS This cross-sectional qualitative study was implemented in four of Tanzania's thirty-one regions. Qualitative data was collected through 26 in-depth interviews held with regional and district disease outbreak response teams, district cold chain co-ordinators and health facility in-charges. In addition, five focus group discussions and seven group interviews were conducted with healthcare workers from the lower-level health facilities. Thematic analysis was conducted and applied the trust constructs. RESULTS Interpersonal trust and health system trust emerged as two major themes in the study. Interpersonal trust was reported to stem from lack of transparency that instigated fear, worries, and confusion regarding the implementation and uptake of the recommended response measures. The distrust was mainly between health professionals in health facilities and those assigned to isolation centres as well as between patients and community members. On the other hand, the health system trust was shaped by mixed feelings regarding COVID-19 vaccine national decisions, and conflicting messages from national officials, politicians and religious leaders on COVID-19 responses, safety, and effectiveness of the vaccines. Questions surrounding the short duration of clinical trials, indeterminate post-vaccination protection duration, impotence-linked beliefs, freemasonry notion and unclear vaccinated cards information are other reported contributory factors to mistrust in the health system. However, after a comprehensive health education and experience in COVID-19 vaccination administration most professionals affirmed the effectiveness of the vaccines in limiting infections and its severe consequences. CONCLUSION Participants indicated limited trust at both interpersonal and health system levels aggravated by lack of transparency, unclear and conflicting messages on COVID-19 infections and response measures. Enforced transparency on pandemics alongside standardised messages from the reliable sources is crucial in enhancing trust in implementation and uptake of the recommended response measures.
