An outbreak of measles that began at a Disneyland theme park in Southern California has resulted in 95 cases that have spread to eight states and Mexico — and many of the victims were not vaccinated, officials say.

The California Department of Public Health has confirmed 79 cases in the state, linking 52 directly to the Disneyland outbreak. There have also been reported cases in Michigan, Arizona, Utah, Washington state, Oregon, Colorado, Nebraska, and Mexico, according to a Los Angeles Times report.

The measles outbreak is starting to infect people in the broader community beyond those who actually visited the park.

So far, nine counties in California have measles cases that have been confirmed, with Orange County reporting 25 cases and Los Angeles County with 16, followed by San Diego County with 13.

Those with measles were as young as 7 months old and as old as 70.

Of the 42 cases where authorities knew the vaccination status of the patients, 34 of them were unvaccinated, and three received a partial vaccination. The remaining five had been vaccinated.

Those who are immunized from measles are safe to go to Disneyland and other areas with large crowds, health officials said. However, the unvaccinated and those with infants who are too young for vaccination should avoid crowds.

Measles can be a dangerous disease with a fever that runs as high as 105, accompanied by a cough, runny nose, eye redness, and a rash on the head that spreads to the rest of the body. In serious cases, it can cause brain inflammation and lead to pneumonia, which can be fatal.

Federal guidelines call for a measles vaccination at 12 to 15 months of age, and a second vaccination between the ages of 4 and 6. Vaccination exemptions are granted to parents who say it conflicts with their personal beliefs, a number that has been growing in recent years over false rumors that it can lead to autism.
