Question:
My question is 'whether a virus by itself lose its infection ability outside host environment' i.e without any chemical agents used on it but only with environmental conditions. And is there any possibility remains that after this it can reactivate when put into host again?



Replies:
Of course yes. Viruses deactivate in unfavorable conditions and can survive for long outside the host body in the form of crystals and can then become alive if introduced back into the host system.

Hi,

Thanks for your answer. You said virus can become alive again in host.Is this true after it has been a long time in environment without host say for months?

regards, Martin
