Due in part to misinformation linking vaccinations to autism, there has been an outbreak of measles in the Pacific Northwest in areas with large populations of parents who refuse to have their children inoculated. Since the beginning of 2019, at least 35 people have been infected, and one child has been hospitalized. Public health officials reportedly estimate the virus could take months to contain.
