The St. Louis Health Department has issued a health alert regarding swimming pools. This is part of a proactive campaign to prevent the spread of an infectious disease called Shigellosis, which has recently affected some child care facilities in the St. Louis area.
Shigellosis is an infectious disease caused by a group of bacteria called Shigella. Shigella symptoms include watery or bloody diarrhea, nausea, vomiting, abdominal cramping, fever, and headache. Symptoms usually appear 1-3 days after exposure and usually last 4-7 days. Some people who are infected may have no symptoms at all but may pass the bacteria to others.
Here's the warning from Health Commissioner Melba Moore: if you operate a pool, check the chlorine, disinfectant, and pH levels frequently. Tell swimmers that they should avoid your pool if they are ill with diarrhea. If you are swimmer, don't swim when ill with diarrhea.
Seems simple enough.
