The number of measles cases linked to having visited Disneyland parks in mid-December has climbed to 22 in California, according to state data. There are four more cases in other states -- two in Utah and one each in Colorado and Washington.
While the incubation period for people who visited the parks between Dec. 17-20 ended on Jan. 10 -- meaning that anyone who was at Disneyland in that time frame would have gotten sick by now -- the Los Angeles Times is reporting that an unvaccinated, infected woman took two flights after she became ill.
The woman was in her 20s, the TImes reported, had visited Disneyland in December and became ill on Dec. 28.
Here's more from the Times:
She flew from Orange County to Seattle on Dec. 29, stayed with family in Washington's Snohomish County and returned to Orange County on Jan. 3. She wasn't diagnosed until Jan. 8 in California, health officials in Washington state said.
The passenger flew to Seattle on Alaska Airlines Flight 505 on Dec. 29, a Washington health official said. She returned to Orange County on Jan. 3 on Virgin America Flight 1780.
Measles is highly contagious, and the virus can live up to two hours on a surface or in the airspace where the infected person coughed or sneezed, according to the Centers for Disease Control and Prevention. Initial measles symptoms include fever, cough, running nose and red eyes. After a few days, a red rash appears on the face and then spreads downward to the rest of the body.
