沖廁不蓋廁板細菌彈上6呎高增倍!減病毒感染宜蓋廁板沖廁自備紙巾

香港曾發布首個「香港市民廁所衞生習慣混合研究」,結果顯示每5名港人之中,只有1人每次沖廁會蓋廁板,超過4成人不蓋。不蓋廁板害處,細菌可彈到6呎高!如果忽視個人衛生,小心病毒找上門。

4成人不蓋廁板沖廁怕污糟

香港大學感染及傳染病中心曾公開一項研究,指公共廁所包括商場、餐廳、車站和街市等廁所,發現44%人不蓋廁板沖廁,而且只有20%人每次會蓋。同時有59%人知道向洗手盆吐痰會增傳染風險,但仍有14%和26%人分別會向尿兜或馬桶吐痰。受訪者解釋因廁板同樣污糟,所以不敢亂碰,而且有受訪者知道踏上坐廁會比較危險,但因為沒有選擇而且較衛生,因此這樣做。

廁板及冲廁掣有較多糞便細菌

負責研究的港大感染及傳染病中心總監何栢良指,廁板及冲廁掣有較多來自糞便和尿液的細菌或病毒,包括金黃葡萄球菌、沙門氏菌及諾如病毒等常見致病病毒。若廁所曾有病人用過,其他使用者或有機會染病。

何又指出曾有研究指沖廁時濺出的水花可噴至6呎遠,故此沖廁前應該蓋上廁板;若廁所通風差,細菌會存在空氣中,更易令用者「中招」(病毒)。另外,如果向尿兜或馬桶吐痰後,應蓋上廁板才沖廁,否則痰中細菌也隨廁所水飛濺;若有人吐痰吐出界,更可能殃及其他用者。

馬桶細菌隨水花飛濺污染廁紙

何栢良亦指有外國研究顯示,因沖廁時的氣流可將馬桶內的細菌沖至6呎外,細菌有可能因為水花飛濺,沾染在廁紙上。而廁格空間愈細,理論上會愈多菌。建議自備紙巾如廁、用濕紙巾、酒精消毒廁板和先蓋廁板沖廁;並用梘液洗手,減少99%至99.9%細菌。
