![]() When COVID-19 worsens, it can progress to severe pneumonia and multi-organ failure. The infection produces COVID-19, a respiratory syndrome characterized by symptoms including fever, malaise, lung infiltrates, dry cough, dyspnoea, and respiratory distress 1. ![]() SARS-CoV-2 spreads from humans to humans. SARS-CoV-2 is phylogenetically related to other zoonotic viruses 1, such as SARS-CoV, the origin of the epidemic of severe acute respiratory syndrome, which caused 916 deaths, as well as MERS-CoV, the origin of the epidemic of the Middle East respiratory syndrome, which caused 858 deaths. Some of those wild animals were sold or consumed at the Huanan Seafood Wholesale Market, located in Wuhan, the Chinese city where the epidemic outbreak started. It is suspected that the reservoir would be bats, but the intermediary is unknown, although snakes, civets, pangolins are candidates 1. This means that SARS-CoV-2 has a wild animal reservoir, and also an intermediate animal, which would transmit the disease to humans. SARS-CoV-2 belongs to the Betacoronavirusgenus 1,3. ![]() There are many species of coronaviruses, all of them belonging to the Coronaviridae family. This Letter aims to discuss the main characteristics of COVID-19 and to raise the need for a multidimensional and multidisciplinary approach to deal with this type of threat to global public health.Ĭoronaviruses (term because of its “crown” appearance in electron micrographs) are a group of enveloped, (+) ssRNA viruses that cause respiratory, hepatic, enteric, and neurological disorders of varying severity in animals, including humans 1,3. COVID-19 has produced millions of infections worldwide, also causing hundreds of thousands of deaths 1, a fact that has led the World Health Organization (WHO) to declare COVID-19 as a pandemic 2.
