Kansas City

Epidemiological Brief

Kansas City presents a LOW epidemic risk score (18.8), with pertussis and measles as the leading weighted contributors. Pertussis incidence of 2.3 per 100,000 — sourced from combined Missouri and Kansas state data — reflects active whooping cough circulation in the region. Measles incidence of 0.2 per 100,000 is moderate for a US venue and suggests ongoing case importation. Influenza ILI% of 3.3% is low, consistent with post-peak seasonal decline. Dengue contributes a low-level signal. Arrowhead Stadium's outdoor configuration mitigates some respiratory transmission risk but does not eliminate crowd-exposure concerns for pertussis and measles. Missouri and Kansas health departments should pre-position rapid diagnostic capacity and MMR emergency vaccination stocks near the venue. Tdap vaccination verification for children and unvaccinated adults is encouraged. The coverage tier is Medium; hantavirus surveillance data for the Kansas City area (a watch signal city) showed no elevated signal at this reporting cycle. Ongoing environmental surveillance should continue through the tournament period.
