Health experts have raised concerns regarding the infection risks associated with poorly maintained public swimming pools and hot tubs. Initial warnings highlighted that inadequate chlorination and filtration can create “bacterial soups” harboring pathogens like Pseudomonas aeruginosa and Legionella.

Subsequent medical advice from specialists has expanded on these risks, specifically noting that improper hygiene and unbalanced chlorine levels can lead to digestive infections from bacteria such as Salmonella, Shigella, and E. coli. Other identified complications include ear and eye infections, as well as potential disruptions to vaginal flora in women.
