Emergency covid-19: A surprising pandemic

Abstract

Coronaviruses are ARN viruses with high variability, widespread in nature in many animal species and in humans, which can cause diseases with varying degrees of severity, from mild forms to severe forms, with high mortality. The COVID-19 emergency evolves into a pandemic, being the main public health concern worldwide. The main manifestations are respiratory, pneumonic, but extrarespiratory symptoms may be present. Hygiene measures are the only ways to prevent now, because there is no a vaccine or antiviral treatment approved for use in patients with COVID-19. Several therapeutic strategies are under study for the new SARS-CoV-2.
