There have not been any measles cases reported in Geary County. But 23 cases have beeen reported in southwest Kansas and others farther south in Oklahoma and Texas.
Geary County Health Department Director Charles Martinez is working to educate the public on this subject.
1. PURPOSE
This memorandum provides a situational overview of the current measles threat in Kansas, with specific implications for Geary County, and outlines public health actions necessary to mitigate potential local transmission.
2. BACKGROUND
Measles, a highly contagious viral disease, has seen a sharp resurgence across several U.S. states. As of March 2025, over 300 confirmed cases have been documented in Texas, with additional outbreaks spreading into New Mexico and Oklahoma. Recently, 10 confirmed cases have been identified in southwest Kansas, increasing the likelihood of intra-state spread.
Measles is transmitted through respiratory droplets and can remain airborne for up to two hours after an infected individual exits the area. With a basic reproduction number (R₀) of 12–18, it is among the most transmissible infectious agents known.
3. DISCUSSION
Geary County currently maintains an MMR (measles, mumps, rubella) vaccination rate of approximately 75%, well below the 93.3% threshold required for herd immunity, as established by CDC and WHO guidelines. This places the local population, particularly young children, immunocompromised individuals, and those medically ineligible for vaccination—at elevated risk.
Complications from measles can be severe and include pneumonia, encephalitis, permanent hearing loss,and death. National surveillance data indicate that approximately 1 in 5 infected individuals require hospitalization (CDC, 2024).
The MMR vaccine is 97% effective after two doses and carries an excellent safety profile. To reduce local risk, the Geary County Public Health Department is mobilizing resources for expanded vaccination clinics, mobile outreach, and community education initiatives.
We urge all residents to verify their MMR vaccination status and take appropriate action. Individuals unsure of their immunization records should consult their primary care provider or contact the health department directly.
4. RECOMMENDATION
In light of the current risk indicators, the following immediate actions are recommended:
• Check your vaccination status. Ensure that you and your children have received two doses of the MMR vaccine. Individuals born before 1957 are generally presumed immune, but others should verify their records.
• Get vaccinated if you're unsure or unprotected. The MMR vaccine is safe, highly effective, and available through your healthcare provider or the Geary County Public Health Department. Walk-in options and special clinic hours will be announced shortly.
• Help protect vulnerable members of the community Infants, the elderly, and immunocompromised residents rely on community-wide vaccination to stay safe. By staying up to date, you’re protecting those who cannot be vaccinated themselves.
• Stay informed
Monitor local media, the health department’s website, or school and workplace updates for new information. In the event of a confirmed case in Geary County, public notices will be issued immediately with exposure locations and instructions. For rural or digitally disconnected populations, outreach will include printed flyers, radio, and community bulletin boards.
• Practice good health habits If you or your child develops a fever, cough, or rash, stay home and call a healthcare provider before visiting a clinic or ER. Early diagnosis and isolation are essential to stopping transmission.
5. CONCLUSION
Measles remains
Measles remains one of the most contagious diseases known, and recent regional cases suggest it could reach Geary County if we are not prepared. Fortunately, we have the tools to prevent it. By working together, staying informed, verifying immunization status, and supporting community vaccination efforts, we can protect our families, neighbors, and health systems. A measured, proactive approach now helps us avoid unnecessary illness and disruption later
