According to a CDPH update Mar. 20, since December, 2014, there have been 133 confirmed measles cases reported in California residents.  No new confirmed cases have been reported to CDPH since the publication of the last report on March 13, 2015

Does this mean the outbreak in the Golden State is over? Not quite yet.

CDPH officials say the outbreak will be considered over when 42 days have elapsed from the end of the infectious period of the last known B3 measles cases that was a not a new importation. As of today (Mar. 20), that date will be April 17, 2015.

The national measles outbreak data from the CDC as of Mar. 13 shows 176 people from 17 states and the District of Columbia were reported to have measles.

Measles is a highly contagious viral disease. It is widespread in many parts of the world, including Europe, Africa, and Asia. Measles begins with a fever that lasts for a couple of days, followed by a cough, runny nose, conjunctivitis (pink eye), and a rash. The rash typically appears first on the face, along the hairline, and behind the ears and then affects the rest of the body. Infected people are usually contagious from about 4 days before their rash starts to 4 days afterwards.

The Centers for Disease Control and Prevention recommends two doses of the MMR vaccine for prevention: the first at 12 months of age, and the second between ages 4 – 6.
