Preventing Recreational Waterborne Illnesses

Recreational water activities, such as swimming in pools, lakes, or beaches, are an excellent way to cool off and enjoy the outdoors. However, it’s important to be aware of the potential health risks that may be present in these aquatic environments. In this blog, we will provide you with a guide to identifying and preventing recreational waterborne illnesses, so you can safely enjoy the water.

What are Recreational Waterborne Illnesses?

Recreational waterborne illnesses are infections or diseases contracted through contact with contaminated water, whether in pools, lakes, rivers, or beaches. These illnesses can be caused by bacteria, viruses, parasites, or fungi found in the water and can result in a variety of symptoms, from mild discomfort to severe illness.

Main Recreational Waterborne Illnesses and How to Identify Them:

  1. Pseudomonas Dermatitis: Also known as “pool dermatitis,” this is a bacterial infection that causes redness, itching, and rashes on the skin. It typically appears within 48 hours after contact with contaminated water.

  2. Swimmer’s Ear (Otitis Externa): This is an infection of the outer ear canal caused by bacteria or fungi. It is characterized by ear pain, itching, redness, and possibly fluid drainage.

  3. Gastrointestinal Infections: These are caused by ingesting contaminated water and can result in symptoms such as diarrhea, vomiting, abdominal pain, and fever.

  4. Protozoan Infections: Some protozoa, such as giardia and cryptosporidium, can cause gastrointestinal infections when ingested. Symptoms include diarrhea, gas, abdominal pain, and dehydration.

Tips for Preventing Recreational Waterborne Illnesses:

  1. Don’t swallow water: Avoid swallowing water when swimming in pools, lakes, or beaches.

  2. Shower before and after swimming: Shower with soap and water before entering the water to remove dirt and germs from your skin. Shower again after exiting the water.

  3. Don’t swim if you’re sick: If you have diarrhea or another gastrointestinal illness, avoid swimming to prevent the spread of germs.

  4. Avoid swimming in cloudy or foul-smelling water: Cloudy or foul-smelling water may indicate contamination, so it’s best to avoid swimming in those conditions.

  5. Use earplugs: If you are prone to ear infections, consider using earplugs when swimming.

  6. Keep the pool clean: If you have a pool at home, make sure to keep it clean and properly disinfected to prevent the proliferation of bacteria and other germs.

  7. Avoid contact with waterfowl: Waterfowl can carry bacteria that can contaminate the water. Avoid direct contact with birds while swimming.


By following these tips and being aware of the risks, you can safely enjoy recreational water activities. Remember to always maintain good hygiene and be alert to any symptoms you may experience after swimming. Have fun safely in the water!
