Implication

Randomized trial shows shifting demographic susceptibility and variant distribution of SARS-CoV-2 in Africa, indicating regional public health needs.

Key Points

This research aims to analyze the distribution of SARS-CoV-2 variants and their association with demographic susceptibility across Africa during the pandemic.
Analyzed 173,194 SARS-CoV-2 genomes from GISAID database from 2020 to 2024.
Conducted Shannon entropy analysis to assess genetic diversity.
Applied Correspondence Analysis to explore variant associations with infection and mortality.
Lineage AY.45 was predominant in South Africa, while AY.34.1 drove transmission in Atlantic West Africa.
Men had a 39% higher risk of infection compared to women (aOR: 1.39, 95% CI [1.34–1.45]), especially linked to clade G.
Later stages dominated by clade GRA affected the elderly (≥70 years; aOR: 1.39, 95% CI [1.33–1.45]) and children (0–9 years; aOR: 1.26, 95% CI [1.20–1.33]).
