家醫科醫師陳爰邑在臉書粉專「家醫科醫師x2.健康和日常都有意思」表示,疾管署最新數據指出,近4週全國已有70起腹瀉群聚通報,發生場所多數在餐飲與旅宿業。在檢驗陽性的案件中,有近九成都是諾羅病毒,其餘一成則是金黃色葡萄球菌與沙門氏桿菌。
根據最新分型結果,GII.17 已成為國內主要流行型別(佔34.2%)。GII.17 並非首次出現,但近年占比快速上升。它的傳播能力比過去常見的 GII.4 更強,更容易造成群聚感染。諾羅病毒的潛伏期大約是10到50小時,如果剛聚餐完,同桌親友都要一起留意身體狀況。
陳爰邑引用美國 2021–2025 年的群聚數據顯示,GII.17 病毒有兩大特徵略高於以往:嘔吐比例更高:高達 78.2%(常見的 GII.4 為 72.2%)。發燒比例增加:約 15.9%(常見的 GII.4 為 10.9%)。住院比例無顯著差異:2.3% vs 2.2%(P=1.000),這表示雖然嘔吐與發燒症狀較明顯,但嚴重度並沒有增加,大家不需過度恐慌。
陳爰邑表示,目前諾羅病毒並沒有特效藥,請掌握以下照顧原則:少量多餐,補充水分與電解質。飲食以清淡為主,吃不下不用勉強吃。嬰幼兒、長輩及免疫力較弱的人,體液流失得快容易造成脫水,需特別警覺,盡早求助。
陳爰邑表示,若兒童出現以下「四大警訊」,請盡快就醫:一直吐、連水都喝不下。精神明顯變差,很想睡或異常煩躁。尿量明顯變少、嘴唇乾裂。拉肚子的情況越來越嚴重。以上都是脫水或病情加重的警訊,有任一項請盡速就醫!同時,聚餐前後一定要記得用「肥皂」勤洗手(酒精對諾羅病毒效果不好)。
