SARS-CoV-2, the virus that causes COVID-19, is spread through respiratory droplets or through contact with a contaminated surface, Chen said. A 75 percent alcohol solution or chlorine solution can sanitize surfaces and kill SARS-CoV-2, but these materials are ineffective against noroviruses and enteroviruses, he said. A 75 percent alcohol solution renders SARS-CoV-2 cells inactive, Tainan Municipal An-Nan Hospital physician Chen Hung-yu (陳泓毓) said. However, because bleach and other chlorine solutions contain hypochlorous acid — which destroys protein structures — they can inhibit the virus’ activity, Chen Hung-yu said. Chlorine solutions should be used within 24 hours after mixing, and should be kept away from direct sunlight and high heat, he said.
