Oregon health officials reported elevated levels of COVID-19, flu, and measles activity across the state. As of September 28, 2026, the state recorded 58 confirmed measles cases, marking the highest total since 1991.
Why it matters
Rising virus activity increases the risk of serious illness and hospitalization for residents, prompting state officials to emphasize the importance of vaccination to maintain community health and daily functioning.
Official state surveillance confirmed 58 measles cases as of September 28, 2026, reaching a level not seen in Oregon since 1991. Testing has also revealed an early-season rise in positive flu results alongside ongoing summer COVID-19 transmission.
The players
CDC
The national public health agency responsible for monitoring infectious disease trends and predicting flu season severity.
The details
Health officials noted that vaccines for COVID-19, flu, RSV, and measles are widely available, with costs covered for most individuals through the Oregon Health Plan and Medicaid. These interventions are designed to prime the immune system to recognize and neutralize pathogens, reducing the likelihood that exposure leads to severe clinical outcomes.
Timeline

Health Landscape
The current uptick in respiratory infections follows a pattern of elevated activity seen since 2021. Oregon's early flu activity aligns with the CDC's forecast for a moderately severe influenza season ahead.
Residents should review their immunization records to ensure protection against measles and other seasonal viruses is up to date. It is worth discussing vaccine eligibility and access through the Oregon Health Plan with your primary care physician.
The takeaway
Vaccination remains the primary tool for reducing the risk of hospitalization during this period of high viral circulation. Contact your local healthcare provider to verify your vaccination status and check your eligibility for coverage.
