KOIN News Oregon has recorded at least 23 total cases of measles in three counties since June 2024, according to state health officials.
So far, the Oregon Health Authority has counted 14 measles cases in Marion County, eight cases in Clackamas County and one case in Multnomah County. In every case, the individual had been unvaccinated. Data show most of the cases have impacted those less than 20 years of age – nine of which were less than 10 years old. Only five cases have been recorded in adults 20 and up.
The first known case took place in Clackamas County on June 11 when an unvaccinated adult began developing a rash, according to the OHA. A few days later, an unvaccinated child in the same household also developed symptoms.
Since then, at least two people have been hospitalized due to infection.
Measles was declared eradicated in the U.S. in 2000, but there have been occasional cases, including an outbreak of 28 reported cases in 2019.
