How hand washing works to control coronavirus
Aug
What makes good hand hygiene so effective against the virus?
When people wash their hands, they may have a perception that they’re trying to kill (amongst others) coronavirus (COVID-19) – but it is in fact “not a living organism” according to a recent report on the Lancaster Guardian website.
Author Rhona Shennan quotes a statement by The Johns Hopkins Hospital which says that “…the virus is a protein molecule which is covered by a protective layer of fat.”
If it’s not actually alive, therefore, it cannot be “killed” – but it can be caused to decay as quickly as possible.
“The virus is very fragile; the only thing that protects it is a thin outer layer of fat and that is the reason why soap or detergent is the best weapon”.
The foam from a soap and water hand wash helps break down the protective fat layer – as does using hot water advises the statement. And it’s most effective given a full, rigorous twenty second wash, which helps to maximise the amount of foam created.
“Dehumidified, dry, warm and bright environments will degrade the virus faster” says the article, which warns that COVID-19 can remain viable in colder temperatures, with cited examples including air conditioned premises and cars.
