As of May 18, 2025, Kansas is experiencing a significant measles spread / outbreak, with 56 confirmed cases reported statewide. Most of these cases—54—are linked to an ongoing outbreak in the southwestern region of the state. Additionally, two cases have been identified in Sedgwick and Reno counties, believed to be associated with international travel. The outbreak has predominantly affected unvaccinated children. As summer travel season begins, we will likely see additional imported cases among Kansans travelling within the United States and internationally.
How Measles Spreads
Understanding how measles spreads will help prevent contracting the disease. Measles is highly contagious—each case can potentially lead to 14 to 18 secondary cases. The virus spreads through respiratory droplets, aerosols, and close contact.
Measles Symptoms and Timeline
It can take anywhere from 6 to 21 days to develop measles after exposure, with a median of 13 days. The virus is contagious 5 days before the rash appears and up to 4 days after.
Early signs include:
- Fever (100.4°F or higher)
- Three C’s: Cough, coryza (runny nose), and conjunctivitis (pink eye)
- Koplik spots: Small red spots with bluish-white centers inside the cheeks (not always present)
The measles rash typically begins around the hairline and behind the ears before spreading down the body. It is not itchy.
Immunity in Infants and Children
Babies receive passive immunity from their immunized mothers, which offers protection until around 6 months of age.
Recommended immunization schedule:
- 6–11 months (international travel): One dose of MMR vaccine (does not count toward the 2-dose series)
- 12–15 months: First dose
- 4–6 years: Second dose to complete the series
What If Your Child Is Behind on Vaccines?
For delayed or catch-up schedules, the two MMR doses must be spaced at least 4 weeks (28 days) apart. The exact timing depends on the child’s age at the start of the catch-up.
Special Recommendations During Community Transmission
In the event of sustained transmission, the Kansas Department of Health and Environment recommends:
- One MMR dose for children 6–11 months
- An early second dose for children 12+ months (before the typical 4–6 year window)
These guidelines are designed to protect the broader community, not just individual cases.
What to Do If You Suspect Exposure
If you think your child has been exposed to measles:
- Quarantine immediately
- Contact your doctor for specific advice
It’s never too late to get caught up on vaccines and reduce the risk of infection.
