'Rapidly changing situation': CDC monitoring 63 patients in 22 states for possible coronavirus

The Centers for Disease Control and Prevention confirmed it is monitoring 63 patients in 22 states for possible instances of the coronavirus, which has spread quickly from its epicenter in Wuhan, China.

Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said Friday that 11 of the 63 patients have tested negative for the virus, while two have tested positive, including a Chicago woman who returned from Wuhan on Jan. 13. The woman, 60, is being treated in isolation and is said to be in stable condition.

The Chicago Department of Public Health and Illinois Department of Public Health are tracking the movements of the woman after she returned to Chicago in an effort to identify others who may be infected. The two agencies confirmed the woman had limited contact and movement outside her home since she returned from China.
