I like the way they say sunlight does disinfect, but nobody knows how long it takes. It is as if they are wanting to disinfect loads. Ok this batch is disinfected, now collect it and put out the next batch. This is not how it works.
Everything that is exposed to the sun gets disinfected over the day or days it is sitting there.
This is just one mechanism to stops the spread of viruses.
@eladarsaid They are very rare. I have gotten many colds over my lifetime, never in the summer.
"Very rare"! What rubbish.
People have colds all year round in UK, anyone would know that
from school attendances; kids have colds. Just before Christmas
(our summer) the whole family had nasty colds and most of my
daughters classmates were off at one time or another.
@wolfgang59said You either did not read or did not comprehend the article.
No, you did not read the article. It said they tested minutes of UVA radiation, not the more destructive UVB. They did not test a typical amount of UVA and UVB tradition a virus exposed outside would recieve in a summer day.
@Eladar From the article
Sunshine solution? Would UVA or UVB work instead? And if so, does this mean you can disinfect things by leaving them out in the sun?
The short answer: possibly – but you wouldn’t want to rely on it.
Bearing in mind that the virus is destroyed in about an hour just sitting on
most porous surfaces and survives 36 hours(ish) on steel I can't see the
value in investigating sticking things in the sunlight. Why do you?
