Summary

This study follows 5,000 Canadian beachgoers to see how different levels of water contact—from wading to swallowing water—affect their risk of getting sick. Researchers will track stomach bugs, respiratory infections, and skin or ear problems in the week after a beach visit. The goal is to provide better safety guidelines and help people make informed choices about swimming at public beaches.
