As of last week, Oregon had reported 20 measles cases since the start of 2026. Measles was declared eradicated in the U.S. in 2000, but falling vaccination rates have driven outbreaks in more than half of U.S. states so far this year. Health officials warn that community transmission in Oregon is beginning to grow and have asked for the public’s help in curbing the spread.

Dean Sidelinger is a health officer and state epidemiologist for the Oregon Health Authority. He joins us with more details about where the outbreak stands and how people can stay safe.
