PHOENIX (AP) — A measles outbreak in Arizona that originated at California's Disney parks is at risk of dramatically increasing in size as health officials keep tabs on 1,000 people in the state's most populous areas.
The number includes nearly 200 children who could have been exposed at a Phoenix-area urgent care center.
Those who weren't vaccinated have been confined to their homes for 21 days, a standard health practice. Some adults have been asked to wear masks if going out in public.
State Health Services director Will Humble says it's possible but unlikely that the outbreak in Arizona can be contained. Arizona has seven confirmed cases.
Maricopa County officials say an Arizona woman who unknowingly had measles visited an urgent care center last week, possibly exposing nearly 200 children.
