【施靜茹】一名女肉販處理牛羊肉而感染副痘病毒，冒出「擠奶人結節」，醫師提醒，家庭主婦處理牛、羊生肉，或小朋友到牧場擠奶，餵小牛、小羊吃東西，手部有傷口最好戴手套。
這名女肉販，每天拿刀切肉賣肉。有一天，她的左手大拇指忽然出現一元硬幣大小的紅色丘疹，丘疹中央潰爛，邊緣水腫，左側腋下也有一顆腫大的淋巴結。醫師問診，她回想在發病一周前，好像在家修剪花木，左大拇指不小心劃傷。
台北榮民總醫院皮膚部主治醫師李定達說，一開始以為女肉販病灶是黴菌感染，在取得病灶組織化驗後，在顯微鏡下，卻發現了橢圓形球狀的副痘病毒，它極頑強，耐乾燥、高溫及有機溶劑，還會汙染飼料槽和飲水槽。
由於這種病毒大多存在牛隻或羊隻身上，透過牛感染稱「擠奶人結節」，被羊感染叫「傳染性膿症」，研判可能是女肉販處理牛羊肉時，病毒從皮膚傷口入侵她身體。
李定達表示，被副痘病毒感染，會經歷丘疹期、箭靶型期、急性滲出液期、乾燥期、疣狀增生期至退化期等六階段，約一個半月才會痊癒，好發在手部或前臂，特別是急性滲出液期如未照料好，容易感染細菌產生蜂窩性組織炎。
李定達說，屠夫、肉販、獸醫、擠奶人、農場工人或畜牧業者是高感染族群；也有的病人不管它，讓傷口自己好，牛羊隻若感染副痘病毒，有可能不進食而死亡，或泌乳量減少。
還好目前副痘病毒，只會經由皮膚接觸受感染牛羊而傳染，並無人傳染人，也無吃受感染牛羊肉而傳染的病例出現。
台北榮總皮膚部主任劉漢南建議，肉販處理牛羊肉，最好戴手套，或到牧場餵牛羊、擠奶時，戴手套較能保護避免感染。
