Flu virus and mycoplasma pneumoniae lead current surge in children’s respiratory infections, experts urge treatment within 48 hours

During the current peak season for respiratory infections in children, the primary pathogens remain viruses and mycoplasma pneumoniae, with the influenza virus being the most prevalent, doctors said at a press conference held by the National Health Commission (NHC) on Sunday, reminding parents to allow their child to remain at home should they contract influenza.

Children with influenza primarily present with fever, and may be accompanied by headaches, muscle aches and general malaise. Additionally, respiratory symptoms such as cough, sore throat, and runny nose may also manifest, according to Wang Quan, a chief physician from Beijing Children's Hospital, during a press conference, according to the CCTV News. In some children, gastrointestinal symptoms may be more pronounced than in adults, manifesting as nausea, vomiting, diarrhea and decreased appetite, Wang added.

The vast majority of children who contract the influenza virus experience an acute, self-limiting course of illness, typically with fever lasting two to three days and making a full recovery within a week, according to Wang.

But Wang noted that some children may experience a cough that persists for an extended period, and others may suffer from fatigue and weakness that last longer than usual.

Parents are advised that if a child contracts the influenza virus, a primary approach should be antiviral and symptomatic treatment. There are specific antiviral medications available for children, which should be used as soon as possible under the guidance of a physician, especially within 48 hours of the onset of symptoms, said CCTV News.

Experts also emphasize that antibiotics are ineffective against the influenza virus.

According to the report released by the Chinese Center for Disease Control and Prevention on Thursday, from December 23 to December 29, 2024, 99.6 percent of the positive influenza virus samples detected in southern and northern provinces of China were identified as H1N1 influenza, said the Health Times affiliated to the People's Daily. 

Experts noted that while the proportion of severe pneumonia caused by influenza is slightly higher than in previous years, the overall incidence remains relatively low. They advise that patients begin treatment as early as possible to ensure a timely recovery.
