The genomic diversity of SARS-CoV-2 Omicron lineages collected during routine sentinel surveillance in Tanzania between November 2022 and July 2023

Abstract

This study provides key insights into the genetic diversity and transmission dynamics of SARS-CoV-2 in Tanzania. It highlights regional discrepancies in lineage distribution, identifying sixteen Omicron lineages and the dominance of clades 22 F (XBB*) and 22E (BQ.1) in the country. The presence of Tanzania-specific clades suggests sustained local transmission of the virus. These findings underscore the importance of enhanced integrated genomic surveillance systems and ongoing monitoring of SARS-CoV-2 evolution.
