What are coronaviruses?

Coronaviruses are named for the crown-like spikes on their surface. Human coronaviruses were first identified in the mid-1960s. Seven coronaviruses can infect people.

Coronaviruses are a large family of viruses that are common in people and many different species of animals, including camels, cattle, cats, and bats. The total number of coronaviruses is not known. Bats can host thousands of types without getting sick.

Coronaviruses that infect animals can evolve and make people sick and become a new human coronavirus. The virus can cause severe acute respiratory syndrome (SARS). Three recent examples of this are SARS-CoV, and MERS-CoV, (Middle Eastern Respiratory Syndrome) and the most recent: SARS-CoV-2
