SACRAMENTO –

49 confirmed cases of measles have been reported in California residents so far in 2014, according to the California Department of Public Health (CDPH).

Orange (21) and Los Angeles (10) are the two counties with the most reported measles cases. The other counties are Riverside (5), San Diego (4), Contra Costa (4), San Mateo (3), Alameda (1) and Santa Clara (1).

According to the CDPH, only four measles cases had been reported at this time last year. The state average each year since 2000—when the disease was declared eliminated in California—ranges from four to 40 cases.

“This dramatic jump in the number of measles cases is a reminder to get fully vaccinated. Being fully vaccinated against measles does more than just protect the person who receives the vaccination—it also protects their family and friends, including children who may be too young to be vaccinated,” said Dr. Ron Chapman, CDPH director and state health officer.

11 of the 49 cases involved patients who had travelled outside of North or South America. These regions include areas where measles outbreaks are happening or where the disease is widespread. 30 cases had patients who had contact with known measles cases, while three cases had contact with international travelers. The other five are under investigation.

According to the CDPH, measles is a highly contagious viral disease which is spread through the air through a cough of a sneeze by someone who has the disease. After fever and other symptoms, a rash begins to spread along the body. Complications and even death can occur in serious cases.

More information about the disease, including symptoms, complications, vaccinations and prevention information, can be found at the Centers for Disease Control and Prevention website.
