An article from 2010 describes how to avoid waterborne water illnesses at sub-tropical beaches:
A yearlong beach study led by a team of University of Miami researchers suggests that swimmers at sub-tropical beaches face an increased risk of illness. The multi-disciplinary team examined the risk of illness that beachgoers face when exposed to recreational marine water at sub-tropical beaches with no known source of pollution or contamination.
Among the top tips from the scientists for a healthy visit to the beach this summer are:
- Avoiding getting beach water in your mouth, or swallowing seawater.
- Practicing good beach hygiene by not swimming when ill with flu-like symptoms, diarrhea or open wounds.
- Showering before entering the ocean and immediately after leaving the water.
- Washing your hands with soap before eating.
- Taking small children to the restroom frequently, while on a public beach.
