There is a lot of confusion as to for how long does the corona virus SARS-Cov2 survives in air or on different surfaces. Recently published study in The New England Journal of Medicine has tried to provide answers to some of those questions.
Another big confusion is around the drugs that are being used in different countries to treat COVID-19 patients. It is important to understand that these drugs although have been tested for the treatment of other diseases, but there are on-going clinical trials that are evaluating their effectiveness for COVID-19. They have been given to severely ill patients, which were hospitalized, but that does not mean that you can start popping anti-malarial pills to protect yourself from getting infected. Stay away from self-medication. Follow hygiene and physical distancing to protect yourself!
