The SARS-CoV-2 epidemic was discovered in December 2019, in the city of Wuhan, Hubei province, China. Its types of transmission are direct contact with the infected person, indirect contact through intermediary objects via the hands and fomites, and the transport of virus-laden droplets in the air. The routes that make its high transmissibility possible are subject to considerable discussion, including the contribution of the aerosol to its transmission. In hospitals, aerosols are formed when performing therapeutic, diagnostic or surgical procedures. The half-life of the virus is around 1,1 to 1,2 h. It can remain stable on plastics, copper, steel and cardboard for 7 to 72 h. Inhalation of airborne droplets is probably the third route of infection. Hand washing, using a mask and keeping your distance are the fundamental prevention measures.
