Core Viewpoint - The article emphasizes the importance of distinguishing between influenza and the common cold, highlighting the need for appropriate medication to avoid complications and mismanagement of the illness [1][2]. Group 1: Differences Between Influenza and Common Cold - Influenza is caused by influenza viruses (type A and B) and is highly contagious, while the common cold is primarily caused by rhinoviruses and coronaviruses, which are less contagious [3]. - Symptoms of influenza include high fever (39-40 degrees Celsius), muscle aches, and severe fatigue, whereas common cold symptoms are milder, typically involving nasal congestion, runny nose, and low-grade fever [3]. - Treatment differs significantly; antiviral medications are effective for influenza and can prevent severe illness, while common cold treatment focuses on symptom relief, with antiviral drugs being ineffective [3]. Group 2: Common Medication Misconceptions - Using antibiotics for fever is a misconception, as influenza is viral and antibiotics target bacteria; misuse can lead to antibiotic resistance [4]. - Stopping antiviral medication prematurely can allow the virus to persist, increasing the risk of recurrence and resistance; for instance, oseltamivir should be taken for a full five days [4]. - Combining multiple medications can be dangerous, as many cold medications contain acetaminophen, and additional doses can lead to overdose, stressing the liver and kidneys [4].

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 causing emerging infectious diseases [1][2][3]. Group 1: Flu Virus Characteristics - The H3N2 subtype is not new and is a common variant, with seasonal fluctuations between H1N1, H3N2, and B-type flu viruses [3]. - Influenza viruses undergo "antigenic drift," leading to seasonal outbreaks, but this does not imply that the virus is becoming increasingly virulent [4][5]. Group 2: Vaccination Insights - With the flu season in full swing, vaccination remains beneficial, even for those who have experienced flu-like symptoms but have not been diagnosed [6][8]. - It is advised not to vaccinate during the acute phase of infection, but individuals can receive the vaccine after recovery from flu-like symptoms [7]. Group 3: Treatment and Symptoms in Children - Antibiotics are ineffective against viral infections like the flu, and treatment should focus on rest, hydration, and symptomatic relief [9]. - Symptoms in children can vary significantly, with older children showing symptoms similar to adults, while younger children may exhibit different signs such as digestive issues [9].

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].

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].
