Heat-Related Illness Surveillance Report

Denton County Heat-Related Illness Surveillance

Although Heat-Related Illnesses (HRIs) are not reportable conditions in the state of Texas, Denton County Public Health conducts syndromic surveillance for HRIs during the summer months. An HRI occurs when the body is unable to cool itself properly, resulting in conditions such as heat stroke, heat exhaustion, heat cramps, sunburn, and even death.

Please find attached the Denton County Heat-Related Illness (HRI) Surveillance Report for Week 39 (September 23 – September 30, 2023).
