Challenges in the fight against the COVID-19 pandemic in university hospitals

Abstract

Coronaviruses belong to a large family of viruses and, for 60 years, have been a known cause of respiratory infection in humans and animals. In December 2019, a novel coronavirus was identified as responsible for the flu syndrome and severe pulmonary complications, the COVID-19. Its origin, still uncertain, is probably related to a mutation in the coronavirus that infects bats, breaking the genetic barrier to adapt to a new species. The original site of transmission was a seafood and live animal market in the city of Wuhan, China. The first cases were linked to individuals who frequented this market. Later, the virus infected family members and, in geometrical progression, nearby provinces, expanding to several countries in all continents.
