Oregon has reported 13 measles cases in the first three months of 2026, with statewide kindergarten vaccination rates falling to 90.5% — well below the 95% herd immunity threshold — and nonmedical exemption rates hitting a record 9.7%. With no Oregon county meeting the herd immunity standard, the state's combination of geographic pockets of under-vaccination and a national measles resurgence that saw the Americas lose elimination status in November 2025 has public health officials warning that a single imported case in the wrong community could trigger sustained transmission.
