Los Angeles County officials warned Thursday that a county resident with measles may have exposed others at several shops on the Westside.
Officials identified businesses in Venice, Brentwood and Santa Monica that the infected person visited, along with a coffee shop in downtown L.A., over a three-day period last week.
The news comes as the country grapples with its worst measles outbreak in decades. As of July 21, 1,148 people nationwide had been diagnosed with measles this year, compared with 372 people in all 2018.
Considered one of the most contagious diseases in the world, measles spreads through coughing and sneezing, but can linger in the air for up to two hours after an infected person leaves the room.
