One of the leading causes of post- swim illness is a parasite called cryptosporidium , which leads to diarrhea, stomach pain and nausea. According to the new CDC report, of the 69 outbreaks associated with treated water, more than half were caused by crypto. Symptoms can last for up to two weeks. The parasite ends up in the water if feces (even trace amounts from someone who didn’t shower first) of an infected person gets in the pool. The bug is resistant to chlorine and survives outside the body for long periods.
Also known as ‘infectious hepatitis’, ‘epidemic hepatitis’ epidemic jaundice – it is an illness that is commonly associated with raw sewage, and in the recreational swimming environment often becomes the most problematic when existing sewage systems become overburdened due to heavy rainfall or flooding. Since this disease is caused by a virus, it does not respond to antibiotics. Hepatitis A is a potential problem when large numbers of people congregate in swimming pools which are unhygienic
Red-eyed after a swim? Was it the Chlorine in the water? Nope, the true cause is nitrogen in urine binding to chlorine to form chloramine—a derivative of ammonia. “It’s not the chlorine itself,” Michele Hlavsa, chief of the CDC’s healthy swimming program, said “It’s chlorine mixed with poop and sweat and a lot of other things we bring into the water with us.” The compound can also make swimmers’ noses run and cause them to cough.
Hot tub Rash
The main cause of itchy skin infection is germs. Chlorine can easily kill the germ that causes it, however, hot water in hot tubs makes chlorine break down faster, so it’s more likely you’d pick it up there.
