After playing in the warm swimming pool, the boy had a sharp pain in his soles. Be careful that this "bacteria" may be at work! In hot weather, people always want to play with water. There is always a heated swimming pool in the indoor swimming area, which is very suitable for children who are afraid of the cold. But a few days ago, a boy came home playing with water, his feet were swollen and painful, and there were a bunch of red lumps. How come... Yu You, an attending dermatologist at Guotai General Hospital, pointed out that a couple of young parents took their son who had just entered primary school to the dermatological clinic a few days ago. The children stumbled and screamed in pain at every step. After listening to their father's statement, they took their children to an indoor water park during the summer vacation. Soon after they came back, many swelling and red lumps appeared on their feet. After diagnosis, the boy was found to have Pseudomonas aeruginosa hot foot syndrome.

What is Pseudomonas aeruginosa hot foot syndrome? Dr. Yu You said that Pseudomonas aeruginosa hot foot syndrome first occurred in 1998. At that time, a group of children had similar symptoms of red lumps on the soles of their feet after using the heated swimming pool in the same community. Later, Pseudomonas aeruginosa was cultivated by bacteria, hence its name.

According to statistics, the symptoms of hot feet suffered by boys will appear within 40 hours after contact. At first, you will feel a sharp pain in the soles of your feet, and then within a few hours, you will start to have many red, swollen, hot and painful lumps, and even you will not be able to walk. In some extreme cases, patients will have severe pain even if they put on shoes and socks or touch sheets. The best hair position is the abdomen of toes, near the front edge of the soles of toes and heels. A few small patients are accompanied by fever and lymphangitis (red linear rash).

One of the culprits is the anti-skid facilities in the swimming pool. Dr. Yu You said that folliculitis caused by Pseudomonas aeruginosa (also known as hot spring folliculitis) is a very common skin disease; Comparatively speaking, hot foot syndrome is rare.

Because Pseudomonas aeruginosa is a kind of bacteria that likes to live in warm water, it may be found in warm swimming pools, spa pools, hot springs and saunas. Although it has not been medically confirmed, at present, it is likely that the bottom of many swimming pools will be made into rough surfaces to prevent slipping, and the feet will constantly rub these rough bottom in the swimming pool, causing slight trauma to the soles of their feet, which gives Pseudomonas aeruginosa an opportunity. The cuticle on the skin surface of children is thinner than that of adults, so it is easier to get Pseudomonas aeruginosa hot foot syndrome.

Pseudomonas aeruginosa hot foot syndrome needs no treatment, and it can be cured within 14 days. Pseudomonas aeruginosa hot foot syndrome does not need medication. Mainly according to the symptoms, oral or external painkillers and ice compress are given to relieve the pain. Most children can recover within 14 days, and nearly 90% children can recover within 7 days.

Dr. Yu You further reminded the operators that once a case of Pseudomonas aeruginosa hot foot syndrome occurs in swimming pools or hot spring pools, it should be thoroughly disinfected to avoid cluster infection. Generally, it is difficult to kill Pseudomonas aeruginosa by chloride disinfection in swimming pools. The bottom of the pool must be thoroughly cleaned with quaternary ammonium disinfectants and treated with ozone to eradicate Pseudomonas aeruginosa.
