An outbreak that started in Clark County, Wash., Continues to grow this week, with 51 confirmed cases at press deadline. (That number rose to 54 on Wednesday.) The majority of cases were children under the age of 10 who had not received the measles-mumps-rubella vaccine.
The outbreak has been fueled by low vaccination rates, as myths about immunizations continue to flummox public health officials. That's a problem in Oregon, too, where one Multnomah County school has a measles vaccination rate of 30 percent.
The exemption rate is initially but has since risen to an all-time high. In 2018, the percentage of non-medical exemptions for one or more vaccines reached 7.5 percent.
Here are the schools with the lowest immunization rates in the county.
