could scientists not dye the corona virus.?

A sort of 'dye before you die' approach?

one dye would eliminate the second die,when you see a guy with a blue nose and a blue mouth you take cover. and get out of a shop if the shelves are all sticky blue gunge

just get a sample of corona and inject a blue pigment into it and they can follow it on its travels with their eyes,and if it reproduced itself and offspring will carry the blue  gene pigment.

lol. But maybe choose a different colour in case people think it's the same as that exploding blue dye that can be placed in a bag of stolen money

corona is named after the Sun so a bright yellow colour is the order of the day.
And the scientists of the world would not have to drink coffee all day they could follow every move the yellow gunge makes and when it stops they could have a coffee

lets put it this way,"they would see corona's next move as it happens".
they could walk into a hospital and tell the cleaner "there is a load of corona on that bed in the corner,please clean it up or someone may catch the virus"

I wonder if it is a mutated Racoon virus...

one coronavirus is a billionth the size of a human cell so good luck finding one

all you need to do is colour a small group of cells ,the gene will carry the colour in development of new cells.
sounds better than trying to track an invisible enemy.you could get them in a blood sample of an infected person.
then inject the dye and bob's your uncle.

I just tried it on my friend and now it looks like he's got yellow jaundice .  Maybe we should have gone for essence of orange peel, make him look like David Dickinson
