Two previous cases were identified in Linn County.

The Oregon Health Authority alerted the public of the first measles case in Clackamas County, following two previously confirmed cases in Linn County.

“The affected individual is unvaccinated. OHA and Clackamas County health officials have not yet determined whether the person has traveled outside of Oregon, or if the case is linked to other known cases, including the two previously reported cases,” the Oregon Health Authority said in a press release.

The pair of Linn County measles cases were both confirmed on Jan. 10. OHA added that those individuals are also unvaccinated and have not traveled outside of the United States.

“State and local officials are working to identify others who may have been exposed to help ensure they are adequately protected against measles. There are currently no known public exposure locations associated with the case. OHA is not identifying the person’s gender, age, or other personal details,” OHA continued.

OHA will update the public with more information on its measles homepage.

“Measles is more than a rash and fever,” said Dr. Howard Chiou, medical director for communicable diseases and immunizations in OHA’s Public Health Division, in the press release. “I worry people aren’t aware that measles can suppress the immune system and increase the risk of severe disease from other infections. Being vaccinated against measles is the best way to protect yourself and your family from getting sick with measles. Everyone should talk with their health care providers to make sure they are up to date with their vaccinations.”
