Measles seems poised to make a comeback in America. Two adults and two children staying at a migrant shelter in Chicago have gotten sick with the disease. A sick kid in Sacramento, California, may have exposed hundreds of people to the virus at the hospital. Three other people were diagnosed in Michigan, along with seven from the same elementary school in Florida. As of [March 7], 17 states have reported cases to the CDC since the start of the year.
It’s true that vaccine attitudes have become more polarized. Conservative parents in particular may be opting out of school vaccine requirements in higher numbers than they were before. In the blood-red state of Idaho, for example, more than 12 percent of kindergartners received exemptions from the rules for the 2022–23 school year, a staggering rate of refusal that is up by half from where it was just a few years ago. Politicized recalcitrance is unfortunate, to say the least, and it can be deadly.
Even so, America’s political divides are simply not the cause of any recent measles outbreak. The virus has returned amid a swirl of global health inequities. Any foothold that it finds in the U.S. will be where hyperlocal social norms, not culture-war debates, are causing gaps in vaccine access and acceptance. The more this fact is overlooked, the more we’re all at risk.
