Recently, after swimming in a local swimming pool, 21 children developed a high fever and other symptoms for several days. As a result, these children tested positive for adenovirus.

So what is adenovirus?

According to, adenoviruses are mainly spread through person-to-person contact, respiratory droplets, and through contact with contaminated surfaces. These infections are more common in children under five years old.

Adenoviruses are a group of viruses that typically cause respiratory illnesses. These symptoms include common cold, pink eye (conjunctivitis), croup, bronchitis, or pneumonia. 

According to Chinese media Red Star News, Mr. Zhang, a Shifang resident, said that his child had a fever for a week, with some days reaching a high of almost 40°C (or almost 104 °F). He added that other kids had similar symptoms, including fever and red eyes. After that, these children were then hospitalized for infusions.

Shifang City released a statement on Saturday stating that the parents of the children who experienced such symptoms after swimming in the Ribo swimming pool were concerned about the water’s quality.

According to the announcement, 21 children with fever tested positive for adenovirus. Up to now, five have recovered, while 16 others are still being treated in hospital.

After receiving feedback from parents, on the evening of July 19, the Shifang Center for Disease Control and Prevention staff randomly inspected the site by collecting water samples from the swimming pool. 

The result reveals that the sample’s levels of urea and total bacteria surpassed the national standards.

After inspection, the swimming pool involved was ordered to shut down. Further investigations are underway.
