A video of tourists crowding the water park has drawn attention in recent days.
In the video, the dense swimming ring fills the entire swimming pool. The people in the swimming ring, regardless of adults and children, are all closely attached to each other. Because it is too dense and there is no space, even if the water waves are surging, people will stay in place. Not moving, unable to move.

What is the "pool killer" adenovirus?
This summer, there have been reports in Sichuan, Hunan, Yunnan, Anhui and other places that some children were infected with adenovirus after swimming in public swimming pools or swimming pools.
What exactly is an adenovirus?
Why is it so easy to get infected in a swimming pool?
Yao Yanqing, Deputy Chief Physician of Pediatrics, Beijing Friendship Hospital Affiliated to Capital Medical University: Adenovirus is actually a viral pathogen. About 5% to 10% of infants and young children in the world have fever caused by adenovirus infection.
Adenovirus is transmitted through respiratory droplets. When we are in the swimming pool, the population is relatively dense. The environment of the swimming pool is humid and the temperature is relatively high, which is very suitable for the virus to survive.
For example, when we are swimming, we are exposed to adenovirus with our hands. If we rub our eyes, nose, or touch our mouth, we may be infected.
Some adenoviruses are also transmitted through the fecal-oral route. Some patients infected with adenovirus may go swimming, and some excrement may end up in our swimming pool. We may swallow the pool water during swimming, so it is possible Can cause adenovirus infection.
Bao Huiling, Deputy Chief Physician of Pediatrics, Peking University Third Hospital: In adenovirus infection, the most important thing is actually children.
Diseases caused by adenoviruses are usually things like upper respiratory tract infections, and also called pharyngeal conjunctival fever, which is pharyngitis, high fever, and conjunctivitis, as well as adenovirus pneumonia.
There is no specific drug for adenovirus treatment. We can only treat symptomatically and supportively, with some immune globulin, and sometimes a little plasma.
There is no cure for adenovirus, so what should a child do if they are infected?
Experts said that adenovirus is divided into mild infection and severe infection.
For children with strong resistance, adenovirus infection is usually mild and can be cured by itself. As long as the child drinks more water, rests more, and relieves fever, there are few sequelae.
And children with weakened immune systems and those with chronic respiratory disease, heart disease, and other medical conditions are at higher risk for serious illness after contracting adenovirus.
Especially once you get adenovirus pneumonia, it can be life-threatening in severe cases.
Therefore, if the child has fever, nasal congestion, cough, etc. after swimming, parents must pay enough attention and take the child to the hospital as soon as possible to avoid delaying the disease.
Which diseases are most likely to be transmitted by swimming in public swimming pools?
The environment of public swimming pools or water parks is hot and humid, crowded with people, and it is very easy to transmit diseases.
So in addition to adenovirus, what other diseases are you prone to contract by swimming in public swimming pools?
Infectious diseases that are prone to occur in swimming places, the following are the most common:
eye disease.
Including acute conjunctivitis, also known as "pink eye", epidemic keratitis and trachoma.
skin disease.
Including tinea cruris, athlete's foot, toenail fungus, etc., what's more dangerous is that if there are patients with gonorrhea in the swimming pool, healthy people may also develop urethra and urinary tract infections.
Otitis media.
When swimming in an unclean pool, once you choke on the water, bacteria or mold will enter the Eustachian tube with the pool water, causing retrograde infection from the inside out.
In addition, unclean pool water can also enter through the external auditory canal, thereby causing otitis media.
Intestinal infections.
When swimming, it is inevitable to choke on water or swallow a small amount of pool water. Viruses and bacteria enter the human gastrointestinal tract with the water, increasing the risk of diseases such as bacillary dysentery and viral hepatitis.
How to choose a safe and hygienic public swimming place?
In order not to be infected with diseases, of course, we must choose to swim in a clean, hygienic and qualified swimming pool.
So how do you judge whether a public swimming pool or water park meets hygiene standards?
The health department reminds consumers that when choosing a swimming pool, they must check whether they have a health license, a health certificate for employees, and an annual test certificate.
At the same time, pay attention to observe whether the swimming pool timely publicizes the self-inspection of the pH value of the pool water and other related indicators in accordance with the regulations.
During the summer vacation, local health and health supervision departments strengthened the inspection and supervision of the water quality of public swimming pools.
The inspectors conduct on-site sampling tests on the pool water, comprehensively test the water temperature, pH value, coliform bacteria, total bacteria and other test contents, and conduct a scientific analysis of the pool water quality.
Liu Yutong, Supervisor of the Comprehensive Third Section of the Health and Health Supervision Center of Dadong District, Shenyang City: If the residual chlorine content of the pool water is lower than the normal standard value, the disinfectant in the pool water may not have an inhibitory effect on the bacteria.
If it is higher than this qualified level, the people who come to swim here may not feel very well, and we will also impose corresponding penalties or conduct circuit supervision.
How to quickly identify whether the water quality of the swimming pool is qualified with the naked eye?
In order to protect the health of swimmers, the relevant departments do have many detailed regulations on the water quality standards of public swimming pools.
But for us consumers, is there any way to quickly identify whether the water quality of the swimming pool is qualified?
Zhu Guangquan: First of all, we can see with our eyes that if the water quality is excellent, a swimming pool with white tiles will appear bright light blue.
There are also swimming pools with light blue tiles, and the pool water will have a dark blue effect.
If the pool water is whitish and slightly turbid, it is likely to be excessive bacteria.
Secondly, we can also smell it with our nose. If you can smell a faint chlorine smell close to the water surface, the water quality is qualified; if the smell is too strong or even choking, it is likely that the disinfectant exceeds the standard, which will cause damage to the respiratory tract and skin.
How should public swimming pools take care of their own health protection?
In summer, in addition to choosing a swimming place with qualified water quality, what protective measures should we take?
Cleanse your entire body before going swimming.
Because when our body has sweat and oil secretion, it will irritate our skin after combining with the chlorine in the water.
Therefore, before swimming, we should try to clean the sweat and oil from the body as much as possible.
It is recommended to take a shower immediately after swimming, clean the nose with sea salt water, gargle with light salt water or warm water, and dry the ears with a cotton swab.
It is impossible to clean the eyes. It is recommended to wear swimming goggles. If the eyes are uncomfortable, you can drop eye drops.
The doctor also reminded that if you are sick and have poor resistance, it is not recommended to swim in public swimming pools.
At the same time, friends with serious cardiovascular and cerebrovascular diseases, skin diseases, and certain infectious diseases should not enter public swimming places.
