Abstract

In this work, we evaluated the levels of genetic diversity in 38 complete genomes of SARS-CoV-2 from five Central American countries (Belize, Guatemala, Cuba, Jamaica and Puerto Rico) with 04, 10, 2, 8 and 14 haplotypes, respectively, with an extension of up to 29,885 bp. All sequences were publicly available on the National Biotechnology Information Center (NCBI) platform. Using specific methodologies for paired F ST , AMOVA, mismatch, demographic-spatial expansion, molecular diversity and for the time of evolutionary divergence, it was possible to notice that only 79 sites remained conserved and that the high number of polymorphisms found helped to establish a clear pattern of genetic non-structuring, based on the time of divergence between the groups. The analyses also showed that significant evolutionary divergences within and between the five countries corroborate the fact that possible rapid and silent mutations are responsible for the increase in genetic variability of the Virus, a fact that would hinder the work with molecular targets for vaccines and medications in general.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding.
