每日英語跟讀 Ep.K344: Soap and water kills viruses better than alcohol
During the COVID-19 pandemic, the government has been promoting frequent hand washing, so many people carry dry hand sanitizer or alcohol disinfectant around with them. Pulmonologist and critical care medicine physician Ooi Hean says that dry hand sanitizer or 75 percent alcohol cannot take the place of hand washing with soap, because alcohol cannot eliminate all viruses.
On his Facebook page, Ooi says that alcohol with a concentration of 70 percent to 95 percent can break down the viral membrane of SARS-CoV-2 and render it harmless. He recommends that when you cannot wash your hands properly, you can sanitize them with alcohol, but that does not mean that all viruses and bacteria will disappear by rubbing with 75 percent alcohol.
Ooi says that enterovirus, norovirus, rhinovirus, poliovirus, hepatitis A virus, foot-and-mouth disease virus and human papillomavirus cannot be eliminated by alcohol, and neither can bacteria such as Bacillus or parasites such as Cryptosporidium.
He says that “regular hand washing” means washing them with soap and water, which will help you avoid spreading the viruses and bacteria that alcohol cannot eliminate to your family members or other people. Ooi said that rubbing your hands with 75 percent alcohol is only for emergency use when there is no soap available, and it cannot completely replace washing your hands with soap in your daily life.
他說，「定期洗手」意味著用肥皂和水清洗它們，這將有助於你避免將酒精無法消除的病毒和細菌傳播給你的家人或其他人。Ooi說，用75%酒精搓手只有在沒有肥皂可用的情況下才有緊急使用，不能完全取代日常生活中用肥皂洗手。Source article: https://www.taipeitimes.com/News/lang/archives/2022/03/12/2003774604
