With spring break here and the summer travel season approaching, the Oregon Health Authority encourages people to make sure they are protected against the measles.
OHA officials said getting the MMR vaccine -- for measles, mumps and rubella -- is the most effective tool against the highly contagious virus.
Twelve US states -- including California, Texas and New Mexico -- have reported cases of measles since January 1st. While Oregon has no cases so far in 2025, the state reported 31 confirmed cases last year -- the highest measles count in more than 30 years -- during an outbreak among unvaccinated people.
Dr. Paul Cieslak, medical director for communicable diseases and immunizations at OHA's Public Health Division, said "measles is an amazingly contagious virus that unfortunately has re-emerged in our communities, primarily due to a declining percentage of people who are getting vaccinated."
Dr. Dawn Nolt, professor of pediatric infectious diseases at OHSU School of Medicine, said the good news is that there is a highly safe and effective vaccine. She said it is the strongest line of defense to keep you, your children and your community safe. If people have questions about the vaccine, she encourages them to talk to their healthcare providers about their concerns.
Dr. Cieslak said anyone planning travel to countries or states where measles is circulating should get the MMR vaccine before they go. He said it will allow you to start building immunity prior to your trip.
