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. A 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.

To date in the 2019 season, there have been 130 cases of HRI in Denton County residents, with 11 of these cases observed in week 36. Seventy-five percent of the reported HRI cases this season have been classified as Heat Exhaustion or Other Heat-Related Illness. Males between the ages of 18 and 35 continue to experience the largest amount of HRI cases among all age groups.

There have been 2 confirmed HRI deaths for the 2019 season; Heat deaths are included in the report after they have been confirmed by a medical examiner.
