Oregon has counted 45 measles cases, its highest total since 1991
Lane County has not announced a local case, but the outbreak changes the vaccine conversation for families planning travel or school.
Oregon has counted 45 measles cases in 2026, the state's largest total since 1991. Lane County has not announced a local case, but statewide transmission is now at a level Oregon has not seen in 35 years.
State epidemiologist Dean Sidelinger told KVAL that parents of children six months or older can ask a pediatrician whether an early MMR dose makes sense during the outbreak. That decision depends on age, travel and exposure risk and belongs with a clinician.
Lane County's public-health page provides local guidance and a vaccine finder. Anyone who suspects an exposure should call before entering a clinic so staff can limit further spread.
Field notes
What changed: Oregon's known 2026 measles total reached 45 as of Wednesday, the most since 1991.
Why it matters: Measles spreads extremely easily, and rising statewide transmission increases the relevance of vaccination and exposure planning even without a confirmed Lane County case.
Who may be affected: Families, schools, health-care settings, travelers and people who cannot receive the MMR vaccine.
