LOS ANGELES (AP) — Health officials say a 7-month-old infant in Orange County and a graduate student who lives in Los Angeles County are the latest confirmed cases of measles in Southern California.

Orange County's health care agency said Saturday that the baby, who was too young to be vaccinated, was treated at an emergency room starting April 28 and remains hospitalized.

The Orange County Register reports the student, a man, is recovering at home in Long Beach. Officials say he could've exposed people to measles at UC Irvine and multiple other locations dating back to April 28.

The number of measles cases in LA County is 8. Orange County has 2 confirmed cases.

Authorities are urging people to get immunized and to learn symptoms of the extremely contagious illness.
