What swims in the swimming pools where we do not care?

pines and water parks accompany summer parties, but they can also be the basis for dangerous bacteria that cause infection.

Health officials in the United States warned about this. In America, of all water bacteria epidemics between 2000 and 2014, one third occurred in pools or hotels. Often, what is needed to preserve a swimming pool or a hot bath has been underestimated.

It is recommended that public swimming pools, including hotel pools and water parks, manage trained people to do so free of pollution.

Most of the U.S. epidemics have been caused by three serious infections -- Kriptosporidium, Legionella, and Perseudemonas.

Cryptosporidium is a very stable parasite to survive even chlorine pools. The common transfusion is to swallow water from the pool, often when contaminated with diarrhea. An infection can cause up to three weeks of serious diarrhea in an infected person.

Peryadomonas and Legionella are bacteria that can challenge disinfectors and live in the cooling of hot pots, pools, and water parks.

These bacteria can enter the body through skin, eyes, or nose. According to a new report, 493 water infection outbreaks were reported in the US with more than 27,000 people.

Legyonella caused 16 percent of the epidemics, and Perseudemonas caused 13 percent. Legyonella can lead to serious pneumonia and flulike symptoms, while pseudomonas can result in ear infections.

People who are more sensitive to Legionella are older than 50, present or former smokers, people with chronic lung diseases, and those with weakened immune systems.
