Spatio-temporal spread and evolution of Lassa virus in West Africa.

ABSTRACT:

Background

Lassa fever is a hemorrhagic disease caused by Lassa virus (LASV), which has been classified by the World Health Organization as one of the top infectious diseases requiring prioritized research. Previous studies have provided insights into the classification and geographic characteristics of LASV lineages. However, the factor of the distribution and evolution characteristics and phylodynamics of the virus was still limited.

Methods

To enhance comprehensive understanding of LASV, we employed phylogenetic analysis, reassortment and recombination detection, and variation evaluation utilizing publicly available viral genome sequences.

Results

The results showed the estimated the root of time of the most recent common ancestor (TMRCA) for large (L) segment was
