Africa: the Covid is going there!

Selfishness. Africa represents more than 30% of the population. Yet officially, the continent has only officially recorded 4% of Covid-19 cases globally; which may seem low, especially in a context where the continent has very marginal access to vaccination. In a recent press release, the ANRS ǀ MIE explains that this low figure is clearly underestimated. Indeed, it is “confirmed that the number of cases [est] significantly higher than that hitherto recorded”, explains the agency. In April 2022, a World Health Organization (WHO) study suggested 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 Re-emerging Diseases in Cameroon, in partnership with the French research unit TransVIHMI , demonstrate a “very strong dissemination of Sars-CoV-2 in Africa according to the different epidemic waves”. These results have been 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 spread reaching 18.6% in Yaoundé (Cameroon) and 17.3% in Conakry (Guinea) after the first wave. , and 51.3% in Yaoundé and 42.4% in Conakry after the second wave. “This very significant spread of the virus in the general population, which contrasts with the number of declared cases, could be explained, among other things, by the frequency of asymptomatic cases within generally young populations”, explains the press release from the agency, which indicates that: ” According to some projections, it could be that more than 60 to 70% of the population studied could have been infected with the different variants of Sars-CoV-2 ”. “These studies provide initial data on the level of dissemination of Sars-CoV-2 within the Guinean population. The results also show that in Africa, the circulation of the virus was more massive than predicted by the statistics from the surveillance. They should allow the authorities to revise 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.
