What Is The Risk Of Bathing In A Pool?

Swimming is a good sport for everyone's health. However, if swimming in an unhygienic water environment, there is a possibility of infection with some microorganisms. Chlorine in swimming pool water does not kill all microorganisms immediately as many people think.
Bacteria resistant to chlorine
There are many species of microorganisms resistant to chlorine. So, even if chlorine water reaches an antiseptic concentration, it can take several hours, even days, to destroy them

. While learning to swim, just swallowing a mouthful of pool water can get sick.
The risk of cross-contamination to healthy people
A healthy, normal, clean person still has 0.14 g of stool sticking on him When pooling, the manure from all bathers can easily contaminate pool water If one of the swimmers has diarrhea, it can spread to everyone in the pool.
Swimming in lakes, rivers, canals, oceans .



... is even more potential than the pool water. Water can be contaminated from upstream, due to many different reasons such as human excrement, animal dung, factory waste, domestic sewage, chemical waste, metal. Water will be more at risk of contamination after a heavy downpour, bringing down waste from upstream
Abdominal pain is a common sign of pool water infection
Do not drink, inhale pool water
Infection can occur when drinking water while swimming, breathing in steam, or by direct contact with pool water, hot tubs, water parks, fountains, lakes, rivers, streams or the ocean
In the common microbiological agent that can be harmful to health in water, Gardia is a type of intestinal protozoan parasite common in our country.
Gardia microorganisms are present in the pool
Gardia disease usually occurs in children more than adults. People infected with Gardia due to ingestion of Gardia's cocoon bodies: by swallowing pool water, streams, lakes, swimming pools, drinking ice made from uncooked raw water, eating Gardia's picky food that can be cocooned.
In addition, close contact with a person who is sick due to Gardia is also a risk of infection.



. Direct contact with patient's blood does not infect Gardia. Cocoons have an outer covering that makes them resistant to physical and chemical agents of the environment.
The source is caused by an infected person or healthy person who has no clinical symptoms. After being cocooned into the body, it will escape cocoon in the small intestine, forming two nutritious forms The phytoplankton reproduces by dichotomy, living freely in the lumen of the intestine, or may attach to the small intestine epithelium. When Gardia moves to the large intestine, she will create cocoons.
Gardia causes digestive disorders that make people suffer from abdominal pain
Gardia cocoons are present in the water by oral ingress
Can be picky about human excretion, infiltrate into other people through the digestive tract, through contaminated food and drink. The Gardia cystic form also follows the stool, but cannot spread the disease because it does not exist in the environment outside the body. Cocoons can survive for weeks or months in the external environment. Gardia is not spread by contact with dogs or cats, which are only parasites in humans.

What are the symptoms of Gardia infection?
People infected with Gardia may have no symptoms or may have acute, or chronic, diarrhea. Incubation period is about 1 to 3 weeks Diarrhea will progress from mild to severe. Patients with stools became more and more fluid, the number of bowel movements increased with mucus, but there was no blood.
Stool has a foul odor, often has bubbles. Diarrhea causes people to become dehydrated, especially dehydration will have serious consequences in infants, children and pregnant women. May include other gastrointestinal symptoms such as abdominal pain, bloating, nausea, vomiting, feeling of fullness, or slight fever, muscle aches, headache.
Gardia's disease lasts from 2 to 6 weeks in a person with a normal immune system. Children, the elderly, and people with chronic illness may extend the duration of the illness. If you are chronically infected with Gardia, the symptoms of diarrhea that occur over and over can lead to malabsorption syndrome.




Children are vulnerable to Gardia when swimming
Is Gardia infection in children dangerous?
In children, severe Gardia infection can cause mental and physical retardation. Gardia makes children lose weight, unable to absorb fat, lactose, vitamin A and vitamin B12.
Gardia is diagnosed by finding cysts and trophic bodies in the stool. Occasionally, multiple stool tests can be performed, so the conclusion is negative only when there are at least 3 negative samples.
How to treat Gardia disease?
There are many drugs used to treat Gardia, the first ones being metronidazole, tinidazole, and nitazoxanide. If the patient is allergic to the above drugs, paromomycin, quinacrine, and furazolidone can be used instead. In addition, the effect of the drug depends on the health of each patient, sanitary conditions and diet.
