近期諾羅病毒變異株（GII.17）於社區活躍，其傳染力極強；

考量無症狀或剛康復之感染者仍具長時間排毒能力，易成為校園內之隱形傳播源，進而引發大規模腹瀉群聚疫情。

諾羅病毒變異株（GII.17）常見症狀有：

水瀉及嘔吐，也有可能噁心、發燒、頭痛、肌肉痠痛、腹部痙攣、胃痛等症狀。

為阻斷隱形傳播鏈並防範校園疫情發生，請落實各項防疫：

包含落實洗手五時機，如廁後、進食前應正確肥皂洗手、食物徹底煮熟，及加強環境清潔消毒。

若出現病毒性腸胃炎相關症狀應居家休息至症狀解除至少 48 小時後再返校。

A variant of the norovirus (GII.17) has recently been circulating in the community and is highly contagious;

Given that asymptomatic individuals or those who have recently recovered from infection can continue to shed the virus for an extended period,

they are likely to become hidden sources of transmission on campus, potentially leading to large-scale outbreaks of diarrhea.

Common symptoms of the norovirus variant (GII.17) include:

watery diarrhea and vomiting, as well as nausea, fever, headache, muscle aches, abdominal cramps, and stomach pain.

To break hidden chains of transmission and prevent outbreaks on campus, please strictly adhere to all epidemic prevention measures:

This includes washing your hands at the five key times—

such as after using the restroom and before eating—using soap and water, ensuring food is thoroughly cooked, and enhancing environmental cleaning and disinfection.

If you experience symptoms of viral gastroenteritis,

you should rest at home until at least 48 hours have passed since your symptoms subsided before returning to school.
