China is experiencing a relatively high rate of influenza, though it is lower than the same period last year and is expected to decrease, according to the National Health Commission on Sunday. Vaccines and treatments remain effective, the commission added.

"The main cause of the recent increase in acute respiratory infection visits to medical institutions is influenza, as shown by monitoring results," said Wang Liping, a researcher at the Chinese Center for Disease Control and Prevention, during a news conference held by the health commission.

"With the imminent closure of primary and middle schools (for the upcoming holiday), influenza activity is expected to decline in the middle and latter part of the month," Wang said.

Although various respiratory infections alternate or overlap in prevalence, all the current pathogens are known, including human metapneumovirus, which has existed for decades. No new infectious diseases have been identified, the researcher added.

The current dominant strain of influenza is the H1N1 subtype. Antigenic analysis of this strain indicates a good match with this year's influenza vaccine, confirming the effectiveness of vaccination, according to Wang.

Wang recommended that everyone over 6 months old without vaccine contraindications, such as allergies to vaccine components, receive an annual flu vaccine. For those who have not yet received this year's flu shot, it remains beneficial to get it. The vaccine provides protection throughout the flu season, reduces the risk of infection, lessens the severity of illness if infected and decreases the likelihood of complications.

Current analyses show that the prevalent influenza virus is sensitive to antiviral medications, indicating that drug treatments are effective.

Most people typically recover from influenza within one to two weeks. However, individuals experiencing symptoms such as high fever, severe cough, difficulty breathing, altered mental state or severe vomiting and diarrhea should seek immediate medical attention, Wang emphasized.

Xu Baoping, chief physician at Beijing Children's Hospital, advised that children with a fever but who are otherwise in good spirits and eating and sleeping normally can be observed and treated at home. However, if high fever persists along with lethargy, rapid or labored breathing, severe vomiting or convulsions, parents should consult a doctor promptly.

With the upcoming 2025 Spring Festival travel rush and expected gatherings, travelers should prepare masks, disinfectant wipes and hand sanitizers, Wang said. Elderly individuals and those with chronic illnesses are encouraged to get vaccinated against COVID-19, influenza and pneumococcal disease.

During travel, wear masks correctly, avoid touching your face and sanitize your hands after touching public facilities. Upon arrival, change clothes and wash your hands and face immediately. If respiratory symptoms develop, stay home and avoid group activities, Wang advised.
