近日，国家流感中心发布的最新一期《流感监测周报》显示，甲流比例明显下降，乙流占比有所上升。继甲流之后，乙流受到公众关注。那么，甲流和乙流究竟有什么区别？乙流会比甲流严重吗？专家详细解读有关甲流和乙流的热点问题。
甲流和乙流都属于流感病毒，但病原体不同。甲流病毒主要表现为高热、咳嗽、喉咙痛等症状，而乙流病毒则以低热、咳嗽、头痛等为主要症状。总的来说，甲流病毒的传染性更强，病情较严重，乙流病毒的传染性和病情相对较轻。
针对乙流病毒，公众应加强预防措施，比如保持良好的个人卫生习惯，避免拥挤的公共场所，加强体育锻炼，保持室内空气流通等。同时，接种流感疫苗也是预防乙流的有效手段。与甲流相比，乙流的严重程度相对较低，但仍需引起足够的关注。
在流感高发季节，如何区分甲流和乙流？专家表示，可通过以下方式进行初步判断：一是观察病情，甲流病情通常较严重，乙流病情相对较轻；二是关注疫情通报，了解当地流感病毒流行情况。三是就医时，向医生说明病情，由专业医生进行诊断。
总之，尽管乙流相较于甲流传染性和严重程度较低，但在流感高发季节，公众仍需保持警惕，加强预防措施。对于疑似病例，要及时就医，确保自身和他人的健康。

Recently, the latest issue of “Influenza Monitoring Weekly” released by the National Influenza Center showed a significant decrease in the proportion of influenza A and a slight increase in the proportion of influenza B. After influenza A, influenza B has attracted public attention. What are the differences between influenza A and B? Is influenza B more severe than influenza A? Experts interpret the hot issues related to influenza A and B.
Influenza A and B belong to the influenza virus, but have different pathogens. Influenza A virus mainly presents symptoms of high fever, cough, and sore throat, while influenza B virus presents symptoms of low fever, cough, and headache. In general, the infectivity of influenza A virus is stronger, and the disease is more severe than that of influenza B virus. The infectivity and severity of influenza B virus are relatively mild.
To prevent influenza B virus, the public should strengthen preventive measures, such as maintaining good personal hygiene, avoiding crowded public places, strengthening physical exercise, and keeping indoor air circulation. Meanwhile, getting the influenza vaccine is also an effective way to prevent influenza B. Compared with influenza A, the severity of influenza B is relatively lower, but it still deserves enough attention.
How to distinguish between influenza A and B in the high-risk season of influenza? Experts say that preliminary judgments can be made through the following ways: first, observe the condition, influenza A usually has a more severe condition than influenza B; second, pay attention to local influenza epidemic reports; and third, inform the doctor of the condition when seeking medical attention, and let the professional doctor make the diagnosis.
In summary, although the infectivity and severity of influenza B virus are lower than those of influenza A virus, the public still needs to remain vigilant and strengthen preventive measures in the high-risk season of influenza. For suspected cases, seek medical attention in a timely manner to ensure their own and others’ health.
