為預防武漢肺炎，要做好自保防疫指施，最重要的就是勤洗手！早前美國有位小學老師，為教導學生勤洗手的重要性，以麵包實驗結果相當驚人，接觸過電腦和沒有洗手摸麵包發霉情況嚴重細菌量眾多，而用酒精搓手液一樣唔夠！
美國小學老師Jaralee Annice Metcalf在Facebook上分享了整個實驗過程，先準備了5片白麵包，第一片接觸電腦表面，第二片沒有接觸過雙手，第三片沒有洗手後接觸，第四片是用梘液洗手後接觸，第五片是使用酒精搓手液後接觸。然後將每片放到密實袋中，因麵包含有防腐劑，需擺放3至4星期後等待結果，實驗結果發現：
結果顯示接觸過電腦表面的麵包最為驚人，幾近變成深灰色，除了帶出需要勤用梘液洗手外，亦帶出了日常觸摸到的地方充滿細菌，需要經常清潔電腦、手機、門把等表面，做足預防措施！
