CHICAGO (Reuters) - A new coronavirus has emerged from Wuhan, China, with more than 300 cases and at least six deaths linked to the respiratory illness believed to have emerged from animals, but with the ability to transmit person-to-person. The virus has spread beyond China's borders, raising concerns of a global pandemic.
Coronaviruses are a large family of viruses common in animals, including camels and bats. Most human coronaviruses, such as the common cold, typically cause mild-to-moderate illness, but some are capable of causing severe disease.
