    With COVID-19 floating around, you know getting your hands clean is your best defense from viruses and bacteria. You use either soap or sanitizer（消毒剂）.But something that’s not as clear is which works better.

1.Wash your hands with soap whenever possible, and if you can’t get to a sink, sanitizer is good, too, according to Preeti Malanti, a medical professor focused on infectious disease at the University of Michigan.

The way sanitizer works is primarily through the power of alcohol. Alcohol can “murder” many types of bacteria and viruses by destroying their outermost layer, making them unable to take over a host. This isn’t effective with viruses with a hard outer shell, like norovirus. 2.Soap works a little differently. Instead of killing viruses and bacteria, its purpose is to lift away dirt, oil, and other dangerous agents that get on your hands.3.It only disinfects（消毒）bacteria and viruses and can leave insect killers or spores（孢子）on your hands.

Washing away the coronavirus might not sound as violent as stopping it dead in its tracks, but it’s proven to be more effective.4.
