Corona viruses are a group of viruses that cause diseases in mammals and birds. In humans, the viruses cause respiratory infections – including the common cold – which are typically mild. Rarer forms such as SARS, REMS and the novel corona virus causing the 2019–20 Wuhan corona virus outbreak can be lethal. In cows and pigs corona viruses cause diarrhea. In chickens they cause an upper respiratory disease. There are no vaccines or antiviral drugs that are approved for prevention or treatment.
