感冒就吃消炎药？流感科学防护指南来了→

Core Viewpoint - The current flu activity in China is on the rise, with the H3N2 virus remaining dominant, and there are no new pathogens detected that could lead to new infectious diseases [1][4]. Group 1: Flu Virus and Variants - The H3N2 subtype is not a new variant and is commonly known [4]. - The flu virus can undergo "antigenic drift," leading to seasonal outbreaks, but such changes do not necessarily indicate that the virus is becoming more virulent [4]. Group 2: Vaccination and Protection - Vaccination remains effective even during the flu season, although it is not recommended for patients in the acute phase of illness [5][7]. - Experts suggest that vaccination during the flu season can still provide protection [7]. Group 3: Treatment and Misconceptions - Antibiotics are ineffective against viral infections like the flu, and the common practice of taking anti-inflammatory drugs for flu symptoms is not scientifically supported [9]. - Treatment for flu should focus on rest, hydration, and symptomatic relief, with antibiotics only used under medical guidance for confirmed bacterial infections [9]. Group 4: Symptoms in Children - Symptoms of flu in children may differ from adults, with older children showing symptoms similar to adults, while younger children may exhibit different signs such as abdominal discomfort [10][12]. - Parents should be vigilant for flu symptoms in children and seek medical attention when necessary [12].
