The confirmed coronavirus patient in Orange County, California, is in isolation at an area hospital in good condition, Dr. Nichole Quick, health officer for the Orange County Health Care Agency, told CNN on Sunday. The patient, a man in his 50s, recently returned from Wuhan through Los Angeles International Airport, though Quick would not confirm whether he returned before or after airport screenings began on January 17.

According to Quick, the county was first alerted to the case on Thursday, January 23. The patient was exhibiting symptoms of upper and lower respiratory tract infections. His test specimens were collected with the help of the US Centers for Disease Control and Prevention, which confirmed the results as positive for coronavirus on Saturday. Upon learning of the positive results, the Orange County Health Care Agency worked with local providers to transport and admit the man to a local hospital.

The man is one of two confirmed cases of Wuhan coronavirus in California – the other being in Los Angeles County. The CDC on Sunday updated the national number of cases to five on Sunday afternoon.
