Yep

[jameskurt]

what elements?? temperature, oxygen....????

[nursegirl6572]

You don't need to concern yourself with EXACT times.  The fact is, it will always vary depending on the situation and the environment.  The thing to remember is that as soon as the virus is exposed to the elements, the process of destruction of the outer shell begins, rendering it unable to infect another person.

[jameskurt]

at that time. 20 seconds, enough to be inactive? Is this true?

Inactivation (inability to infect others) of the virus is almost instant after its exposure to atmospheric oxygen
