Knowledge and practice of personal protective measures against COVID-19 in Africa: a systematic review

BACKGROUND

The Coronavirus disease 2019 (COVID-19) pandemic being a newly evolving disease, its response measures largely depend on the practice of and compliance with personal protective measures (PPMs).

OBJECTIVE

This systematic review aimed to examine the knowledge and practice of COVID-19 PPMs in African countries, as documented in the published literature.

METHODS

A systematic search was conducted on Scopus, PubMed, and Web of Science databases using appropriate keywords and predefined eligibility criteria for the selection of relevant studies. Only population-based original research studies (including qualitative, quantitative, and mixed-method studies) done in Africa, and published in the English language were included. The screening process and data extraction were performed according to a pre-registered protocol in PROSPERO (CRD42022355101) and followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The quality of included studies was assessed using the Mixed-Method Appraisal Tool. Thematic analysis was used to systematically summarise the studies into four predefined domains: i) knowledge and perception about PPMs, ii) mask use, iii) social/physical distancing, and iv) hand washing/hygiene, including their respective levels and associated factors.

RESULTS

A total of 58 studies across 12 African countries were included, and these were published between 2019 and 2022. African communities, including various population groups, had varying levels of knowledge and practice of COVID-19 PPMs, with lack of personal protective equipment (PPE) (mainly face masks), and side effects (among health care workers) being the major reasons for poor compliance. Lower rates of handwashing/ hygiene were particularly noted in several African countries, especially among the urban poor and slum-dwellers, with the main barrier being the lack of safe and clean water. Various cognitive (knowledge and perception), socio-demographic and economic factors were associated with the practice of COVID-19 PPMs. Moreover, there were evident research inequalities on the regional level, where East Africa contributed 36.2%, West Africa 20.7%, North Africa 17.2%, Southern Africa 6.9%, and no single-country study from Central Africa. Nonetheless, the overall quality of the included studies was generally good, as they satisfied most of the quality assessment criteria.

CONCLUSIONS

There is a need to enhance local capacity to produce and supply PPE. Consideration of various cognitive, demographic and socioeconomic differences, with extra focus on the most vulnerable, is crucial for inclusive and more effective strategies against the pandemic. Moreover, more focus and involvement in community behavioral research are needed to fully understand and address the dynamics of the current pandemic in Africa.

CLINICALTRIAL

The study protocol was registered in PROSPERO (CRD42022355101).
