Health officials warn public of possible measles exposure in San Francisco

SAN FRANCISCO (KGO) -- The San Francisco Department of Public Health is alerting anyone that might have been in contact with a person infected with measles to check with a physician if they experience any symptoms.

"We are getting the information out to our riders along the 49 - 47 lines to let them know that there was someone riding with measles, and if you're feeling any of the symptoms that normally come with measles, to go see a physician," said Paul Rose, SFMTA Spokesperson.

The San Francisco Department of Public health believes the risk to the general public is very low.

"The measles virus is airborne and so it can stay in the air for up to an hour after somebody who was contagious with measles was in that space," said Dr. Julie Stoltey.

On Wednesday April 3, the individual spent two hours at Hayes Valley Bakeworks, located at 525 Golden Gate Avenue.

Symptoms can emerge eight to 12 days after being exposed.

"The symptoms of measles start with a running nose, a cough and watery eyes and a fever. The fever can be quite high and after a couple of days people will typically develop a rash that starts on the head and then spreads downward," said Dr. Stoltey.

The CDC reports a total of 465 cases of measles in 19 states since January. That's the second highest number of cases since 2000.

"Increases nationally and now we are seeing cases in California as well, so our best protection is to have our population vaccinated against measles," said Dr. Stoltey.

The individual lives in Santa Clara and is currently recovering at home. No other cases have been reported.
