The battle to halt the spread of the measles outbreak that began at Disneyland has required both infectious disease expertise and a good amount of old-fashioned detective work.
Health officials in California and seven other states have painstakingly traced the steps of measles patients, tried to identify anyone who came in contact with them, and quarantined those at greatest risk of getting the highly contagious disease to keep the virus from spreading.
It’s a trail that has taken them to grocery stores, gyms, farmers markets, hospitals, post offices, banks, schools, a casino and even Starbucks and Wal-Mart. Shoppers at Costco in Gilroy were greeted with a public notice stating: “If you were in this store on Sunday January 18, 2015 between 4:00-6:00 p.m., you may have been exposed to measles.”
In Arizona, which is hosting the Super Bowl on Sunday, health officials have been busy compiling a list of 1,000 people who might have been exposed to measles based on the movements of seven infected patients.
