What is a common preventive measure to avoid RWIs at swimming pools?

A common preventive measure to avoid Recreational Water Illnesses (RWIs) at swimming pools is requiring individuals to shower before entering the pool. This practice helps to rinse off any dirt, sweat, saliva, and other contaminants that can introduce pathogens into the water. By encouraging swimmers to shower, facilities can significantly reduce the number of bacteria and viruses present, thereby decreasing the likelihood of RWIs. This step is essential in maintaining water quality and ensuring a safe swimming environment.

Maintaining clean water is vital for public health, and requiring a pre-swim shower is an effective way to start that process. Good hygiene practices among swimmers can lead to a healthier swimming experience for everyone.
