Today we know that COVID-19 spreads through airborne particles as well as droplets. This article was published in April 2020, before this was common knowledge.
Good hygiene and physical distancing are the best ways to protect yourself and everyone around you from the novel coronavirus (COVID-19) according to the World Health Organization. The virus spreads through droplets expelled by a person who has the disease, including by contact with surfaces a sick person has touched. Because most of us can’t isolate ourselves entirely, good hand hygiene can be the final barrier between us and the disease.
When applied to hands thoroughly and scrubbing for at least 20 seconds, both soap and alcohol-based hand sanitisers will stop the coronavirus.
If you are already sick, no amount of soap, alcohol or other household disinfectants will help you. Do not try to ingest or breathe soap or other cleaning products. Consult a doctor instead. But even though it won’t help you personally, good hygiene will help keep the people around you safe.
