Measles is Circulating in the Bay Area: Make Sure You're Protected!

 
 

California is experiencing a large outbreak of measles. Although measles has not been confirmed in a San Francisco resident in 2015, there have been workplace and BART exposures. The outbreak began in December 2014 when at least 40 people who visited or worked at Disneyland theme park in Orange County in mid-December contracted measles and it has now spread to at least half a dozen other states.

 

The best way to prevent measles is to get vaccinated. Many people have already received two doses of measles vaccine, called MMR and are considered immune to measles, but others may still need one or two doses of vaccine.
