Abstract

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.
