Abstract

BEDOYA-SOMMERKAMP, Marcelo et al. SARS-CoV-2 variants: epidemiology, pathophysiology and the importance of vaccines. Rev. perú. med. exp. salud publica [online]. 2021, vol.38, n.3, pp.442-451.  Epub Sep 30, 2021. ISSN 1726-4634.  http://dx.doi.org/10.17843/rpmesp.2021.383.8734.

SARS-CoV-2 is a single-stranded RNA virus of the coronavirus family, which causes COVID-19 (Coronavirus Disease 2019). This virus is responsible for the current pandemic, which, since its emergence in late 2019, has caused millions of deaths and has had a global impact not only on public health but also on social and economic areas. Therefore, this article aims to review the most up-to-date information on SARS-CoV-2, beginning with the description of the pathophysiology and phylogenetics of the virus. Also, we will present the emerging SARS-CoV-2 variants, their relevance for local and global public health, their epidemiology in Peru, and finally, the role and importance of vaccines in this context.

Keywords : SARS-CoV-2; COVID-19; epidemiology; pathophysiology; vaccines.
