W.H.O is saying this thing is air borne it can last I think 72 hours on plastic surfaces so who knows how long it can drift for they also said it lasts a long time on your eyes due to the moistness there so its virulent, adaptable and when we get a vaccine for it we will see how long before it morphs. They are saying the vaccine may only protect you for 3 months so its all like a craps game throw the dice and see what happens.............................
