Hello,I think there are many askers concern about this question,include me.
For the viewpoint “Any body fulid once leave people, exposed to air,lose the infectious immediately”.I have some questions about it.Please give me accurate answers.I believe if people read this post,they will not ask the similar questions any more,and you will save much time.
1. In this viewpoint ,the author don't state the amount of body fulid,if the amount is large, accordind with "lose the infectious immediately" or not?
2.If a drop of blood fall on a table,it is a irregular sphere,the outer virus is destroyed by air immediately,but how about the virus inner of the irregular sphere? also destroyed immediately or not?
3.Are there requirement about temperature,humidity etc?If no matter about these environment conditions,it is always "lose the infectious immediately"?
4.How understand “IMMEDIATELY” ,is there a superior limit time?For 1~3 drops of blood,3 seconds is short or longer?
5.How understand “exposed to air”?If a little oxygen,such as:
5.1 a drop of blood in someone's pocket
5.2 a man who have a spermatorrhoea on his knickers in the daytime,if it is winter,the man wear many clothes(oxygen is little,and it is body surface temperature,near to inner temperature)
5.3 If blood is on a table,but there is an object(such as a cup) cover on the blood,the blood which is covered is exposed or not?
Are 5.1 ~ 5.3 accord with “exposed to air”,if always “lose the infectious immediately” or not?
