Houston

Epidemiological Brief

Houston carries a LOW epidemic risk score (21.5), though it hosts elevated dengue and pertussis signals among US cities. Dengue incidence of 0.05 per 100,000 generates a notable weighted contribution (adj 34.4) given Houston's subtropical climate and Aedes aegypti vector presence. Pertussis incidence of 2.3 per 100,000 is among the highest in US host cities and reflects active community transmission in Harris County. Influenza ILI% of 2.4% is low, consistent with Texas's earlier seasonal peak. Measles and mpox components are present but modest. NRG Stadium venue operators should coordinate with Harris County Public Health on outdoor spectator areas and vector control, particularly during evening matches. Tdap booster verification is recommended for staff and unvaccinated attendees. Dengue-suspected presentations with fever and myalgia in returned travelers should be tested promptly; clinical staff should be familiar with dengue triage criteria. Houston's high coverage tier (High, 93%) reflects robust surveillance inputs, providing confidence in the risk characterisation.
