What Was the Measles Outbreak
In early 2015, public health agencies identified a multi-state measles outbreak linked to exposure at Disneyland in California. The outbreak quickly spread to several other U.S. states and drew attention to vaccination coverage gaps.
How Measles Spreads and What Symptoms Appear
Measles is a highly contagious virus that spreads through coughs and sneezes. Common symptoms include high fever, cough, runny nose, red eyes, and a rash that usually begins on the face and spreads downward.
Public Health Response and Prevention
Health officials promoted measles vaccination as the most effective prevention method. They also traced contacts, issued isolation guidance, and used public messaging to encourage immunization and limit further spread. For more details, see the CDC overview at CDC Measles Outbreaks.
