Houston faces heightened risks from mosquito-borne diseases as temperatures rise, with experts warning that environmental changes could exacerbate these threats. Dr. Sarah Gunter from Baylor College of Medicine highlights how rising temperatures and increased humidity can accelerate mosquito development and virus replication. As Houston enters peak mosquito season from May to October, urban environments pose unique challenges due to artificial breeding sites. While West Nile virus is a primary concern, most infections are mild. Health officials recommend using repellents with DEET or oil of lemon eucalyptus and treating clothing with permethrin for protection. Residents are encouraged to monitor local mosquito-borne disease risks through the Harris County Mosquito and Vector Control website.
