近日，广东省佛山市一所高中发生诺如病毒感染事件，共有74名学生出现呕吐、腹泻等症状，经疾控部门确认为诺如病毒感染。诺如病毒是一种高度传染性的肠道病毒，主要通过被污染的食物、水源、接触感染者或其排泄物传播。该病毒在人群密集场所（如学校、养老院）极易引发聚集性疫情。目前，当地教育和卫生部门已启动应急响应，对涉事学校进行消毒、隔离病例，并暂停集体活动以防止疫情扩散。专家提醒，预防诺如病毒感染的关键在于保持良好的个人卫生习惯，如勤洗手、不共用餐具、避免食用未煮熟的海鲜等。大多数患者症状较轻，通常在1–3天内自愈，但婴幼儿、老年人及免疫力低下者需特别警惕脱水等并发症。此次事件再次凸显校园传染病防控的重要性，相关部门应加强健康教育和日常监测，筑牢公共卫生防线。
Recently, a high school in Foshan City, Guangdong Province, reported an outbreak of norovirus infection, with 74 students experiencing symptoms such as vomiting and diarrhea. Local disease control authorities confirmed the cases as norovirus-related. Norovirus is a highly contagious gastrointestinal virus primarily spread through contaminated food or water, direct contact with infected individuals, or exposure to their feces or vomit. It easily causes outbreaks in crowded settings like schools and nursing homes. In response, local education and health authorities have activated emergency protocols, implementing thorough disinfection, isolating affected students, and suspending group activities to curb further transmission. Experts emphasize that prevention hinges on good personal hygiene—frequent handwashing, avoiding shared utensils, and refraining from consuming undercooked shellfish. Most cases are mild and resolve within 1–3 days, though infants, the elderly, and immunocompromised individuals should be monitored closely for complications like dehydration. This incident underscores the critical need for robust infectious disease prevention measures in schools, including enhanced health education and routine surveillance to strengthen public health defenses.
