Measles Exposure in Spokane County
Aug 19, 2025

Spokane, Wash. – Local public health officials have confirmed a measles infection in a Kootenai County resident with exposure risk in Spokane County.

Most people have immunity to the measles through vaccination, so the risk to the general public is low. However, with confirmation of measles virus here, Spokane Regional Health District (SRHD) is advising individuals to check their children’s and their own vaccination status and verify that they are up-to-date with the measles mumps rubella (MMR) vaccine.

Before receiving the measles diagnosis, the individual was in the following public locations. Anyone who was at the following locations during the times listed was possibly exposed to measles:

Tuesday, Aug. 12, 11:14 a.m.-5:27 p.m., Providence Sacred Heart Pediatric and Adult Emergency Departments
Wednesday, Aug. 13, 6:02 p.m.-12:54 a.m., Providence Sacred Heart Pediatric and Adult Emergency Departments
Friday, Aug. 15, 9:30 a.m.-8:27 p.m., Providence Sacred Heart Pediatric Oncology & Hematology Specialty Clinic​...

Spokane County resident presumed to have measles following exposure, symptoms
Aug. 25, 2025 Updated Tue., Aug. 26, 2025 at 8:34 a.m.​
By Amanda Sullender

Though test results have yet to confirm it, a Spokane County child has almost certainly contracted measles, according to local health officials.

The first case of measles in a Spokane County resident this year, the presumed diagnosis comes after two cases were identified in North Idaho earlier this month. One of those individuals traveled from Bonner County to Providence Sacred Heart hospital in Spokane to receive treatment before they were diagnosed.

It was during this visit where the Spokane County individual was likely infected. On Sunday, they received treatment for measles-like symptoms. Results from a measles test will not be available until Wednesday...

...The Spokane County resident is a child under 10. Their vaccination status is unknown, Hawkins said.

The case comes with a whole new set of exposures that may have taken place when the child received treatment Sunday. Anyone who was at the Providence Sacred Heart emergency department on Sunday, Aug. 24 between 6:08 a.m. and 10:41 a.m. was possibly exposed.

The following locations of potential measles exposure relate to the previous Bonner County, Idaho , case.

Tuesday, Aug. 12, 11:14 a.m.-5:27 p.m., Providence Sacred Heart Pediatric and Adult Emergency Departments
.
Wednesday, Aug. 13, 6:02 p.m.-12:54 a.m., Providence Sacred Heart Pediatric and Adult Emergency Departments.
Friday, Aug. 15, 9:30 a.m.-8:27 p.m., Providence Sacred Heart Pediatric Oncology & Hematology Specialty Clinic.

According to Hawkins, the Spokane County child was not in any other public place since when they could have been infectious.

Asked if more measles cases are likely in Spokane County, Hawkins said that“would not be surprising.”​...
