A virus is obligate intracellular organism.A virus can only carry out it
biological processes such as reproduction in a living cell i.e a virus
will remain inactive for as long as it is out of a living cell.Because
it reside inside the living cell,it can not be killed without killing
the cell.it is for that this reason that H.I.V is very difficult to be
killed.Hope to share more next time .Bye for now.
