In the hot summer, many people bring their families to swimming pools or water parks to play in the water and escape the heat. While enjoying the coolness, we must also remind everyone to be careful about contracting "swimming pool disease."

Recently, a parent in Hefei, Anhui took his 5-year-old son to a water park to play. After returning home, he found large and small bumps on the child's face. After examination, he found that it was molluscum contagiosum.

Skin diseases that can be contracted through swimming pools includeMolluscum contagiosum,besidesImpetigo、FolliculitisDisinfectants in swimming pools can also cause some childrenSkin allergiesIf the swimming pool water quality is not up to standard, the girl may be infectedBacterial vulvitis。

Gao Ying, deputy chief physician of the Dermatology Department 1 of the Children's Hospital affiliated to Capital Institute of Pediatrics:In summer, the weather is hot and humid, and children may be bitten by insects or scratched, causing minor skin injuries. Children's skin is relatively delicate, so it is easy to get infected.

In addition to skin diseases, children should also pay special attention to ear diseases when swimming. If the ear canal is damaged, pool water entering the ear canal may causeOtitisSome children frequently choke on water while learning to swim, which may causeOtitis media。

Lu Yingxia, chief physician of the Department of Otolaryngology and Head and Neck Surgery at the Children's Hospital affiliated to Capital Institute of Pediatrics:Otitis media has nothing to do with water ingress, but with choking on water. Children who are not very good at swimming are prone to choking on water, and dirty water may enter the middle ear through the throat tube, causing otitis media. Otitis media can also cause ear pain and hearing loss.

Don't panic if water gets into your ear canal. It is important to drain the water in time.

According to the doctor, otitis media usually hurts when the ear is touched and can be cured by topical anti-inflammatory drugs. Otitis media is different. It hurts even if the ear is not touched. You need to go to the hospital for standardized treatment, otherwise it will cause hearing damage.

Doctors remind children not to panic if water enters the ear canal while swimming, because there is an eardrum inside the ear canal, which is like a dead end, and water will not pass through the eardrum into the inner ear.As long as you tilt your head and jump on one leg, the water will flow out on its own. Parents should try not to use cotton swabs to insert into the child's ear canal to absorb water, as this can easily damage the ear canal and increase the chance of infection.。

Swimming pools and water parks that do not meet hygiene standards can also spread "pink eye". Even in swimming pools that meet hygiene standards, some children are allergic to the disinfectants in the pool.Cause eye discomfort。

Zhang Hao, deputy chief physician of ophthalmology at the Children's Hospital affiliated to Capital Institute of Pediatrics:For example, if there is a lot of eye mucus, we can buy some tobramycin eye drops or levofloxacin eye drops for the child, and it may be cured in a few days. If there is not a lot of eye mucus, and it is mainly itchy and red, you can use some anti-allergic eye drops, such as olopatadine eye drops. Sometimes the allergy is more severe and may even cause conjunctivalEdema, this situation can be solved by, for example, weakhormoneEye drops to control symptoms.

In addition, if the water quality in swimming places does not meet the standards, it may also spread respiratory diseases, such asAdenoviruswait.

According to doctors, adenovirus is mainly transmitted through droplets, contact, and fecal-oral infection, and is more easily transmitted in closed, crowded, and humid environments. The temperature and humidity of swimming pools are suitable for the survival of adenovirus, so many children developRepeated high fever and coughSymptoms such asPharyngoconjunctival fever, gastroenteritis, and diarrhea。

Zhang Qiang, deputy chief physician of the Department of Pediatric Infections at Anhui Provincial Children's Hospital:You should choose a regular swimming pool, that is, one that meets the standards of disinfection and hygiene. After swimming, you should wash your eyes, nose, mouth, and body.
