Africa: the Covid is going there!

selfishness. Africa represents more than 30% of the population. Officially, however, the continent has only officially registered 4% of the world’s Covid-19 cases; which may seem low, especially in a context where the continent has very little access to vaccination. In a recent press release, the ANRS ǀ MIE explains that this low figure is clearly underestimated. In fact, it is “confirmed that the number of cases [est] significantly higher than before,” explains the agency. In April 2022, a study by the World Health Organization (WHO) indicated that the actual number of Sars-CoV-2 infections could be up to 97 times higher than the number of reported cases. Two international projects: Ariacov and Covepigui, coordinated by the Center for Research and Training in Infectiology of Guinea (Cerfig) and by the Center for Research on Emerging and Reemerging Diseases in Cameroon, in partnership with the French research unit TransVIHMI, demonstrate a “very high spread of Sars-CoV-2 in Africa according to the different epidemic waves”. These findings were published in the journals Emerging Infectious Diseases and Open Forum Infectious Diseases. Surveys conducted in Cameroon and Guinea between December 2020 and June 2021 showed similar results, with virus prevalence after the first wave in Yaoundé (Cameroon) 18.6%, in Conakry (Guinea) 17.3% and in Yaoundé 51% .3% and 42.4% respectively. in Conakry after the second wave. “This very clear spread of the virus in the general population, in contrast to the reported cases, could be partly explained by the frequency of asymptomatic cases among the general young population,” explains the agency’s press release. which suggests: “According to some projections, it could be that more than 60 to 70% of the population examined could be infected with the different variants of Sars-CoV-2”. “These studies provide initial data on the spread of Sars-CoV-2 within the Guinean population. The results also show that the spread of the virus in Africa was more massive than the surveillance statistics predicted. They should allow authorities to review vaccination strategies against Covid-19 with the aim of efficiency and rationalization of resources,” says researcher Abdoulaye Touré, co-investigator of the Covepigui and Ariakov studies in Guinea.
