Summer is officially here—and with it comes the desire to head to the nearest pool or water park. However, with the number of pool-related illnesses like cryptosporidium on the rise, the Centers for Disease Control and Prevention (CDC) warns that it is even more important to follow proper pool safety rules and regulations.
What is cryptosporidium?
“Cryptosporidium is a microscopic parasite that can be found in drinking water and recreational water like pools,” says Jesse Couk, M.D., an infectious disease specialist at Piedmont. “Most infections are caused when people ingest contaminated water. Caregivers can also become infected by handling contaminated feces, such as when changing a diaper.”
Symptoms of cryptosporidium
Cryptosporidium typically causes watery diarrhea, which can last up to three weeks. Other symptoms may include:
- Abdominal pain
- Fever
- Nausea
- Vomiting
The infection can also result in dehydration and weight loss.
Though anyone can contract cryptosporidium, certain people are more susceptible to becoming seriously ill. This includes:
- Children
- People with abnormal immune system
- Pregnant women
According to Dr. Couk, cryptosporidium is primarily treated through supportive measures.
“It’s important to stay hydrated, replacing fluids that are lost,” Dr. Couk says. “Your physician may also prescribe nitazoxanide, an antiparasitic drug that is used to treat diarrhea in those suffering from cryptosporidium.
How to protect yourself from cryptosporidium
Cryptosporidium is considered a “chlorine-tolerant parasite,” and it is difficult to kill. According to the CDC, even the most common well-maintained pools are at risk for the parasite. To protect yourself from contracting the parasite, Dr. Couk offers the following tips:
- Don’t swim if you have diarrhea.
- Shower before and after you get into the water.
- Avoid swallowing water while swimming in pools, water parks, lakes, rivers, or hot tubs.
- Wash your hands before eating or preparing food or after handling diapers.
