Measles cases in Oregon are ticking up. Here’s what you need to know
Key Points:
- Measles has resurged in the U.S. due to declining vaccination rates, with over 2,000 cases and three deaths reported last year, and widespread outbreaks occurring in multiple states including South Carolina, Utah, and Florida.
- Oregon has reported a modest number of cases so far in 2026, but experts believe the actual number is higher due to undetected cases and wastewater data; no major outbreaks have occurred yet, but unvaccinated communities remain vulnerable.
- Measles is highly contagious, capable of lingering airborne for up to two hours, and individuals are contagious before the rash appears, making early spread easy and often unnoticed.
- Vaccination provides strong protection: two doses offer about 97% lifetime immunity, while unvaccinated individuals face a 90% risk of infection upon exposure; vaccination within 72 hours of exposure can reduce severity or prevent disease.
- Measles can cause serious complications, especially in young children, including hospitalization, pneumonia, and rare fatal neurological conditions; vaccination has prevented millions of deaths globally since its introduction.
