One Out of Three Diseases Occur In Hotels’ Swimming Pools | Says A Research

Swimming is a great exercise, that’s what we all know of and in fact, that has been discussed previously in this article as well. Most people swim as a form of exercise but others swim because it’s their hobby. And whether it’s taken as a form of exercise or hobby, swimming is really helpful in keeping your muscles in motion as well as in strengthening your overall bones. We had discussed how swimming can be helpful in keeping your body in shape earlier in this article. However, could swimming be harmful too? That’s the real question. Because that’s what research says.

Earlier, in a research, it has been narrated that swimming can be harmful to people’s health too. And this normally happens in the hotels’ swimming pools and the bathtubs of these hotels. Cryptosporidium, a parasite, Pseudomonas and Legionella, bacteria are said to be the cause of spreading these harmful diseases. The reason behind is that despite having some maintained pools which are cleaned on regular basis, some of these parasites and bacterial manage to survive in this environment which further causes diseases like gastrointestinal illnesses.

Diseases caused by Legionella, Pseudomonas & Cryptosporidium

Out of 363 diseases caused by all these parasites and the bacteria, 212 were said to be caused by Cryptosporidium alone which makes it about 58%.

57 out of 363 are caused by Legionella which makes it about 16%. And 47 of these out of 363 are caused by Pseudomonas which makes it about 13% of the total.

As per the official reports, because of these parasites and the bacteria, at least 27,219 cases were reported who got infected while because of the same infections, 8 deaths were confirmed.


Legionella bacteria can cause the following diseases:

  • Legionella can cause Legionnaires’ disease, a form of pneumonia which can become severe and is only caused when a person inhales the bacteria itself.
  • Legionella can further cause Pontiac fever, a kind of fever which is similar to having influenza. This too is caused by Legionella infection.

Reports say that the 6 out of 8 deaths which have been mentioned above were caused because of Legionella bacteria.


Pseudomonas bacteria cause the following diseases:

  • Pseudomonas bacteria can cause the folliculitis. Folliculitis is a kind of condition of a skin in which can cause inflammation of skin hairs. Initially, it might look like pimples or red bumps on the skin.
  • Another infection which can be caused because of pseudomonas is otitis externa, also known as swimmers’ ear. A kind of state in which the ear canal gets inflamed and results in pain and swelling of the ear.


Cryptosporidium can cause diarrhea.

The cause of diseases

It’s said that normally the diseases which were reported were caused by the parasite cryptosporidium.

The leading cause of cryptosporidium happens when a swimmer who is a victim of diarrhea enters into the pool and allows the parasite to remain in the swimming pool. This makes the swimming water infected which results in other swimmers getting infected and sick when they accidentally end up swallowing the water of the swimming pool.

The detrimental part here is that Chlorine cannot keep the bacteria out of the swimming pool. The bacteria has to be prevented from entering in the swimming pool in the first place and that’s possibly only when the swimmers before entering into the pool ensures that they don’t have any disease like diarrhea or that they don’t have any symptoms left of any such disease which can result in infecting the pool.

Disinfectants cannot kill such bacteria. Thus, taking preventive measures is necessary while using the swimming pools of the hotels. It is also highly recommended that before you enter the pools, you make sure that you check your health condition as well.
