Disease that can happen by swimming in Dirty Pools


The germs and bacteria that cause recreational water illnesses include E.Coli, Hepatitis A, Giardiasis, Pseudomonas Aeruginosa, and cryptosporidium. Studies found that 58 percent of the tested public swimming pools had E-coli. The presence of E-coli is an indication that faecal matter existed in the pool largely due to the fact that most people fail to shower before getting into the pool.


Giardiasis is a condition that occurs when swimmers swallow contaminated water. The condition causes various unpleasant symptoms that include constant diarrhoea, abdominal cramps and weight loss for an extended period of up to three weeks. When chlorine levels are not sufficient in a pool, the Hepatitis A virus can be lurking putting swimmers at serious risk of developing life-threatening liver failure.


If Cryptosporidium, which can stay in the pool for up to 10 days, is swallowed, it can cause gastrointestinal tract problems including diarrhoea. Pseudomonas Aeruginosa is a major cause of skin rashes and painful ear infections. Furthermore, swimming in highly chlorinated pools can also put children at risk of developing respiratory illnesses like hay fever and cancer.
