What are coronaviruses?
Coronaviruses are a family of viruses that cause infection in humans and various animals, including birds and mammals such as camels, cats and bats. Some animal coronaviruses are zoonotic, meaning they are communicable from animals to humans. To date, it has been confirmed that seven coronaviruses can also cause infection in humans. When animal coronaviruses evolve, infect humans and spread between humans, this can lead to outbreaks such as MERS-CoV and SARS.
