Denton County Public Health monitors heat-related illnesses during the summer. This is done through syndromic surveillance, even though these illnesses are not required to be reported in Texas.

Heat-related illnesses occur when the body cannot cool itself properly. This can lead to various conditions, including heat stroke and heat exhaustion. Other possible outcomes include heat cramps, sunburn, and even death.

Further information on heat-related illness surveillance is available from Denton County Public Health. Residents of Trophy Club can consult the county's resources for more details on this topic.
