PHOENIX (AP) -- Arizona's top health official says the state appears to have "dodged a bullet" on a potential measles outbreak.
That's the assessment of state Health Services Director Will Humble several weeks after Maricopa County health officials said an unvaccinated person with measles may have spread the highly infectious disease around parts of the Phoenix area.
Health officials said at the time they were worried about a possible outbreak because of a person who returned from Europe with the measles in late March.
According to health authorities, measles symptoms typically surface within seven to 12 days of exposure but some cases take as long as three weeks.
Humble now says health officials haven't found any secondary cases so far and that means Arizona appears to have avoided an outbreak.
