Introduction:
Swimming is not only a fun recreational activity but also a great way to stay active and cool off during the hot summer months. However, swimming in contaminated water can lead to the transmission of recreational water illnesses (RWIs), which are caused by germs found in pools, hot tubs, lakes, rivers, and oceans. Knowing the risks associated with RWIs and taking necessary precautions are essential for enjoying safe swimming experiences. In this blog, we’ll explore the basics of RWIs and provide practical tips for avoiding them.
Recreational Water Illnesses
Recreational water illnesses are caused by a variety of germs, including bacteria, viruses, and parasites, that can thrive in aquatic environments. These germs can enter the body through ingestion, inhalation, or contact with contaminated water and can cause a range of symptoms, including gastrointestinal, respiratory, ear, and skin infections. Common RWIs include:
-
Cryptosporidiosis:
This diarrheal illness is caused by the parasite Cryptosporidium, which is highly resistant to chlorine and can survive in properly treated water for an extended period. It is often transmitted through swallowing water contaminated with Cryptosporidium, leading to symptoms such as diarrhea, stomach cramps, nausea, and vomiting.
-
Giardiasis:
Giardiasis is another diarrheal disease caused by the parasite Giardia lamblia (Giardia). It is commonly found in untreated or inadequately treated water sources such as lakes, rivers, and poorly maintained swimming pools. Symptoms include diarrhea, gas, abdominal cramps, nausea, and dehydration.
-
Norovirus:
Norovirus is a highly contagious virus that causes gastroenteritis, commonly known as the stomach flu. It spreads through fecal-oral transmission, often via contaminated water or food. Norovirus can cause symptoms such as diarrhea, vomiting, nausea, stomach pain, and fever.
-
Swimmer’s Ear (Otitis Externa):
Swimmer’s ear is an infection of the outer ear canal, typically caused by bacteria or fungi. It occurs when water remains trapped in the ear after swimming, creating a moist environment conducive to bacterial or fungal growth. Symptoms include ear pain, itching, redness, drainage, and decreased hearing.
-
Skin Infections:
RWIs can also manifest as various skin infections, including:
-
- Folliculitis (Hot Tub Rash): This bacterial infection of the hair follicles can result from exposure to contaminated water in hot tubs or pools. Symptoms include red, itchy bumps or a rash.
- Cellulitis: Cellulitis is a bacterial skin infection that can occur when bacteria enter the skin through cuts, abrasions, or breaks in the skin barrier. It can cause redness, swelling, warmth, and pain in the affected area.
- Molluscum Contagiosum: This viral skin infection causes small, raised bumps on the skin. It can be transmitted through direct contact with contaminated water or surfaces in swimming pools or other recreational water sources.

Swimming Precautions
To reduce the risk of RWIs and ensure a safe swimming experience, consider the following precautions:
- Choose Swimming Locations Wisely:
Select swimming venues that are properly maintained and have good water quality. Public pools and beaches with regular water quality testing and maintenance are generally safer options.
-
Check Water Quality:
Before swimming, check the water quality reports for public pools, beaches, and recreational water facilities. Avoid swimming in bodies of water that have been recently contaminated or have advisories for poor water quality.
-
Avoid Swimming with Open Wounds:
Refrain from swimming if you have open wounds, cuts, or abrasions, as they can increase the risk of infection by allowing germs to enter the body more easily.
-
Practice Good Hygiene:
Shower with soap and water before and after swimming to remove germs and reduce the risk of spreading infections. Encourage children to take bathroom breaks and avoid swallowing pool water.
-
Don’t Swim While Sick:
Avoid swimming if you have diarrhea or any other contagious illness to prevent spreading germs to others and contaminating the water.
-
Wear Protective Gear:
Use waterproof earplugs to prevent water from entering the ears and causing swimmer’s ear. Wear swim goggles to protect your eyes from irritation and infection.
-
Stay Informed:
Stay informed about RWIs and their symptoms, and seek medical attention if you develop any signs of illness after swimming. Report any suspected cases of RWIs to the appropriate health authorities.
-
Maintain Proper Pool Chemistry:
If you own a pool or hot tub, maintain proper water chemistry and filtration to prevent the growth and spread of germs. Regularly test and adjust pH, chlorine, and other chemical levels according to industry standards.
Conclusion:
By following these swimming precautions and staying informed about RWIs, you can minimize the risk of illness and enjoy safe and healthy swimming activities. Remember that preventing RWIs requires a collective effort from swimmers, pool operators, and public health authorities to maintain clean and well-maintained swimming environments.
