Health officials now confirm 11 cases of measles in Arizona

(AP) — An outbreak of measles that began with an inmate at a federal detention center for immigrants in central Arizona has now grown to 11 confirmed cases, officials said Monday.

State and county health officials said they're working to stop new transmissions by isolating patients, vaccinating people detained in the privately-run facility and trying to identify people who were at locations the four infected workers visited.

Health officials have identified 14 locations in Pinal and Maricopa counties where the infected workers may have exposed other people, including stores, restaurants and a tribal casino.

"People who have a rash and fever must call their health care provider or emergency department before going to let them know they may have measles," Dr. Cara Christ, director of the state health department, said in a statement.
