Abstract
In late December 2019, a group of patients with "atypical pneumonia" of viral etiology was reported in Wuhan, China. We now know that coronavirus disease 2019 (COVID‑19) is caused by the new coronavirus SARS‑CoV‑2 that produces an acute disease with respiratory predilection and high contagiousness, whose origin is the result of natural selection between species. The World Health Organization declared this event as a public health emergency of global concern. The clinical presentation is diverse, from asymptomatic or mildly self-limiting upper respiratory tract disease to the development of severe and progressive interstitial pneumonia with the development of multiple organ failure and death. To date there is no specific treatment. Epidemiological measures of social distancing, hand washing and the use of personal protective equipment reduce the spread of this virus in the population. The aim of this review was to describe the existing information about SARS‑CoV‑2 and the COVID‑19 pandemic, which allows health personnel to better understand the origin, epidemiology, clinical evolution, diagnosis, and current experimental treatments for this new disease. Therefore, it was carried out an evaluation of the bibliographic information with the terms coronavirus, COVID‑19, and SARS‑CoV-2 in the specialized databases in English and Spanish.
