The World Health Organization (WHO) points to evidence that the Coronavirus can be suspended in the air in certain environments after coughing and sneezing – 239 scientists from 32 countries signed a document stating that these droplets can infect those who are at a considerable distance, especially in poorly ventilated or closed.

‘Since the beginning of the pandemic, there have been studies indicating a potential for transmission of the virus by aerosol, which is contagion through microdroplets released by the simple act of speaking or breathing. They are up to a thousand times smaller than what we call ‘losers’, expelled when we cough or sneeze. In closed environments, these microdroplets that carry the virus can be suspended in the air for up to 16 hours, and contamination can occur in these conditions’, observes Professor Viviane de Souza Alves, from the Department of Microbiology at the Federal University of Minas Gerais (UFMG) , Brazil.

She points out that no research has been able to conclude that this is exactly the behavior of the Coronavirus.
