Measles cases have now been reported in 12 Kansas counties, according to the Kansas Department of Health and Environment’s 2025 Measles Case Data dashboard.

Health officials recently corrected earlier data, reassigning two cases from Haskell County to Seward County. However, Seward County currently has no active outbreak-related cases.

Confirmed measles cases have risen slightly in recent weeks, increasing to 90 as of Wednesday, up from 86 on July 7. Most cases—87 of them—are tied to an outbreak in southwest Kansas. Eight patients have been hospitalized, one more than earlier this month. No deaths have been reported.

Ten counties in southwest Kansas have had outbreak-related cases: Finney, Ford, Grant, Gray, Haskell, Kiowa, Morton, Pawnee, Seward, and Stevens. Of those, only Gray, Haskell, Morton, and Stevens still have active outbreak status. Counties are considered “active” for 42 days after their last reported outbreak-linked case.

Reno and Sedgwick counties have also reported measles cases, though they are not connected to the outbreak.
