TAHLEQUAH, Okla. — In working with the Oklahoma State Department of Health (OSDH), the Cherokee Nation was notified of a case of measles within the Cherokee Nation Reservation that was confirmed on April 24.
Cherokee Nation Public Health and Cherokee Nation Health Services, working with the OSDH, are identifying and contacting individuals directly who may have been exposed during April 14-17.
The Cherokee Nation recommends that Cherokee citizens contact their primary care provider to ensure they are up to date with all vaccinations.
MMR vaccination is the most important tool to prevent measles. The vaccine is safe and effective in protecting someone from measles expected at 93% after the first age-appropriate dose, and 97% after the second.
According to the OSDH, as of April 25, 2025 there have been 15 cases of measles identified in Oklahoma.
The Cherokee Nation continues to prepare for any future potential measles cases and works diligently to ensure the best quality of health and well-being for its citizens and community partners.
Anyone who suspects they may have the measles or have been exposed to someone with measles should not walk into a clinic, hospital, or urgent care without calling first to protect others.
