Distribution of Covid-19 in African, European, American and Asian ethnic groups resident in Port-Gentil, Gabon between April 2021 and March 2022

Introduction: The pandemic caused by COVID-19 has upset the world and especially in Sub-Saharan Africa or most countries that do not have equipped laboratories, qualified human resources, tests available for tracking suspected cases, and large-scale testing of the population, making the response a daily challenge for the entire decision-making chain. In order to break the chain of transmission, Gabon has shown itself to be an example in the application and compliance with barrier measures and especially in the availability of RT-PCR tests in a very heterogeneous population characterized by significant dynamics. Objective: the objective of this work was to show the distribution of COVID-19 in a population made up of several ethnic groups (continental origins) in the city of Port-Gentil between April 2021 and March 2022. Methodology: We conducted a cross-sectional study at the 1st Medical Biology Laboratory for descriptive purposes. Participants of all ages from Africa, Europe, America, Asia, and Oceania, regardless of gender, were included in the study. A database was constructed, and the statistical analyses were carried out using Epi Info 7. The significance threshold was set at 0.05. Results: 20984 participants were enrolled with 78% of African origin, 14% of European origin, and 5% of Asian origin. The population’s average age was 43.14±10 years, with six times more men than women. The prevalence in the population was 8.65%. The proportion of positive women was twice as high as that of men at 14% (P<0.00001). The proportion of positive people by continental origin was higher in Europe and America (white person) with 9.35% and 9.45%, respectively, compared to Africans and Asians with 8.74% and 6,60%, respectively.
