Core Viewpoint - The current flu season in China is experiencing a rapid increase in activity, with the H3N2 virus remaining dominant, and experts clarify that there are no new pathogens detected [1][3]. Group 1: Flu Virus Characteristics - The H3N2 subtype is not new and is a common variant, with known pathogens circulating rather than unknown ones [3]. - Influenza viruses undergo "antigenic drift," leading to seasonal outbreaks, but this does not imply that the virus is becoming stronger over time [5]. Group 2: Vaccination Insights - Despite the flu season being in full swing, it is still beneficial to receive the flu vaccine, especially for those who have recovered from flu-like symptoms [7][9]. - Vaccination is recommended after symptoms have subsided, and it is not advisable to vaccinate during the acute phase of infection [7]. Group 3: Prevention Strategies - A dual prevention strategy of vaccination and maintaining good hygiene practices is advised to mitigate flu transmission [11]. - Antibiotics are ineffective against viral infections like the flu, and symptomatic treatment is recommended instead [12][14]. Group 4: Pediatric Considerations - Symptoms of flu in children can differ from adults, with younger children potentially showing less typical signs [15]. - Parents should monitor for severe symptoms in children and seek medical attention if necessary [17].
