Just when you think you can enjoy a refreshing swim, the Centers for Disease Control and Prevention (CDC) has issued warnings about a concerning parasite known as “cryptosporidium,” often shortened to “crypto.” This parasite, which can survive for up to 10 days in chlorinated water, poses a risk that surpasses the usual concerns surrounding E. coli, which is typically neutralized within a minute in well-maintained pools. Intrigued by these revelations, I decided to explore the CDC’s Healthy Swimming app to better understand the potential germs we might encounter in communal swimming spaces. Here are some surprising takeaways I gleaned:
1. Shared Filtration Systems
Many swimming facilities may utilize a shared filtration system across multiple pools. This means that if one individual consumes contaminated shellfish, it could potentially expose many others at the waterpark.
2. Resilience of Crypto
The resilience of crypto is attributed to its tough outer shell, allowing it to withstand chlorination and remain infectious even in treated water.
3. Backyard Pools
Backyard pools, particularly inflatable ones, can act as breeding grounds for recreational water illnesses (RWIs) since they often lack chlorine and filtration systems.
4. Drinking Pool Water
Drinking from public pool water is highly discouraged—no matter how tempting hydration may seem during hot summer days. Additionally, it’s advisable to avoid sitting on jets, as these can direct concentrated streams of possibly contaminated water towards you.
5. Interactive Water Features
Interactive water features, such as spray parks, may be fun, but they can also be vectors for disease. In fact, a single incident at a spray park in 2005 resulted in approximately 1,700 infections, with 425 confirmed cases of crypto.
6. Awareness of Diarrhea Risks
Alarmingly, over 20% of American adults are unaware that swimming while experiencing diarrhea can contaminate water. While I personally find the idea of swimming in such a state repugnant, it’s clear that awareness is lacking.
7. Hot Tub Statistics
The United States boasts over 7.3 million operational hot tubs, a statistic that can be shared to lighten the mood after discussing such a serious topic.
