These signs are required by many health departments (and recommended by the CDC) to prevent the spread of Crypto (Cryptosporidium), a chlorine-resistant parasite. They strictly prohibit anyone who has had diarrhea in the past 14 days from entering the water. For more details on these specific warnings, view our collection of active diarrhea pool signs.
Health codes typically state that swimmers must wait at least 14 days after diarrhea symptoms have stopped before entering a pool. This is because the body can still shed parasites like Cryptosporidium for weeks after symptoms disappear. Ensuring proper compliance starts with clear pool rules signs.
Signs should be posted at the entrance to the pool area and in locker rooms or pool changing room signs. Placing them in highly visible spots ensures that all patrons read the health warnings before showering and entering the water.

Teenagers would often laugh at such disclaimers but people with active diarrhea using pools is not funny. Instances of waterborne diseases breaking out in pools are frequently attributed to people who have experienced diarrhea recently. Also, the disinfectant properties of Chlorine may not always be sufficient to eliminate the viruses or parasites that can be transmitted by those individuals.
