Climate change is having an unprecedented influence on human health. For example, increased frequency of storms with excessive precipitation may contribute to flooding, which contributes to increased water-related dermatological, gastrointestinal, and respiratory illnesses. Some of these water-related illnesses, which can be transmitted via recreational waterborne pathways, may be seen in school-age children. The purpose of this article is to raise awareness of the impact some recreational water-related illnesses have on school-age children's health and to provide school nurses with information on the signs and symptoms of these illnesses as well as prevention tips nurses may wish to share with parents. This is the third article in a series meant to inform school nurses about illnesses linked to local changes in weather that may be arising from global changes in climate and provide them with the tools they need to safeguard children's health.
