Health alert: Measles cases identified in Clackamas and Marion counties
There are three reported cases of measles in Clackamas and Marion counties, with two of those cases based in a single Clackamas County household, according to Oregon Health Authority (OHA). There are no exposures identified in Washington County at this time.
Anyone who has received a measles vaccination at any time in their life has a low risk of getting measles. By comparison, that risk is much higher for anyone who hasn’t received a measles vaccine before exposure to the preventable disease. Groups at highest risk of getting measles include:
- Unvaccinated pregnant people.
- Infants younger than 1-year-old
- People with weakened immune systems.
To protect yourself and your children, call your health provider if you notice any of the symptoms mentioned on this page. Vaccination remains the most effective way of protecting yourself against measles, so please ensure you are up to date on your MMR or MMVR vaccine.

Measles is a very contagious disease caused by a virus. It affects the respiratory system (lungs and breathing tubes) and causes a fever and a rash. Other symptoms include cough, runny nose, and red, watery eyes. Measles can be serious, especially for babies and young children. It is mainly spread through the air after a person with measles breathes, coughs or sneezes. Measles symptoms usually begin 7-14 days after exposure to the virus. Measles is contagious from about four days before the rash appears through four days after the rash appears. People can spread measles before they have the characteristic measles rash.

Measles is rare in the United States. People are usually exposed to measles when they travel internationally, and unvaccinated people can get infected abroad and bring the virus back to the U.S.
If you think you might have measles, call your doctor. If you need to be seen by a doctor, be sure to call before you arrive so that plans can be made to avoid exposing other people.
Measles is preventable with a vaccine called "MMR" (measles-mumps-rubella).
