Abstract
Introduction :
Several theories have attempted to explain the slow progression of SARS Cov-2 infection and its lethality in Africa. The first forecasts made a case of a massacre in sub-Saharan Africa (SSA) because of the weakness of the health system. The objective of this mini-review is to analyze the different theories and hypotheses explaining the low progression of COVID-19 in sub-Saharan Africa.
Methodology :
A literature search was carried out on PubMed, Web of Science, Scopus and Science Direct using the following keywords: Coronavirus, Covid-19, SARS-CoV 2, climate and sub-Saharan Africa. The study included articles published between January 5, 2020 and August 30, 2021.
Results :
Out of a total of 217,491,077 cases and 4,519,193 deaths from COVID-19, Sub-Saharan Africa accounts for only 3.5% of cases and 4.3% of deaths. Various hypotheses on this weak progression of Covid 19 in SSA have been put forward: the virulence of the viral strain, young age, low population density, co-infections, cross-immunity, chemoprophylaxis, temperature high and ultraviolet (UV).
Conclusion :
weather conditions of which UV, age and ecosystem have been identified as important elements in correlation with the incidence of COVID-19. However, this situation should not ignore the need for vaccination coverage against the coronavirus and the use of other preventive measures against this pandemic in SSA.
