What are coronaviruses?

Coronaviruses are a large family of viruses that often cause respiratory tract infections. Common human coronaviruses cause upper-respiratory tract infections with symptoms of the common cold. Occasionally, human coronaviruses can cause lower-respiratory tract infections, like pneumonia. Two other human coronaviruses, MERS-CoV and SARS-CoV, may cause severe infections.
