PHOENIX (AP) — Maricopa County health officials say an unvaccinated person who has measles may have spread the disease around portions of the Phoenix metropolitan area.
They are trying to identify additional cases and stop a possible outbreak of the contagious disease.
Health officials say the person returned from Europe with the measles late last month and visited several areas in Scottsdale and Cave Creek between March 29 and 31 in addition to Sky Harbor Airport's terminal 4.
That person hasn't been identified yet.
Authorities say measles symptoms typically surface within seven to 12 days of exposure but some cases take as long as three weeks.
The disease is spread through coughing, sneezing and contact with certain body secretions and can survive outside the body for hours.
