First Measles Case in Over 30 Years Reported in Kootenai County

The Idaho Panhandle Health District has confirmed a measles case in Kootenai County, marking the first instance in more than three decades.

According to PHD, the infection was identified in an unvaccinated child. This represents the first reported case in Idaho since 2023 and the first in the northern Panhandle since 1991. The health district is currently investigating how the child contracted the virus and reaching out to locations visited by the child during the infectious period to alert potential contacts.

Measles is known for its high contagion rates, easily transmitted through the air when an infected individual breathes, coughs, or sneezes. Remarkably, the virus can linger in the air for up to two hours after the infected person has left the area.

Symptoms generally appear about seven to 14 days after exposure and can include elevated fever, coughing, a runny nose, red eyes, and a characteristic rash. While many people do recover without serious issues, measles can lead to significant complications, particularly in very young children and those with compromised immune systems.

PHD recommends that everyone check their family’s vaccination status with a healthcare provider. Individuals are deemed immune if they were born before January 1, 1957, have a confirmed history of measles, or have received both doses of the MMR vaccine.

The measles vaccine is highly effective; for most individuals, two doses during childhood will provide lasting protection. In the U.S., the MMR vaccine is typically administered to children between 12 and 15 months, with a second dose given at ages 4 to 6. For those traveling to regions with known outbreaks, the vaccine can be given as early as 6 months old.

In 2024, there was a rise in measles cases across the U.S., and already in 2025, the number of cases has surpassed the total from the previous year, reported in 41 jurisdictions, including Washington, Montana, Oregon, and Wyoming. Notably, 13% of those affected have required hospitalization, most of whom are children.

If you or a family member begins to show symptoms of measles, it’s crucial to contact your primary care provider right away. PHD stresses the importance of reaching out to your healthcare professional before visiting in person.
