why hiv outside the body is different (teak and HHH, MD)

[milito0213]

taek said， hiv is not alive outside the body ;but  HHH, MD said：...HIV can survive outside the body.  For what it's worth, the time is highly variable, from a few seconds to several days, depending on temperature, humidity, the nature of the secretions, the surface they are on, etc.
but why?

There is no specific time, but it is very short because it is very fragile. Less then 1 minute.

How long can HIV survive outside the body after all?

There is no question on HIV's inability to survive outside the body. The only place where it can survive outside the body is inside the bore of a needle, which won't survive very long either.

This was said by Dr.HHH 6 hours ago, "HIV and other STD pathogens die promply on exposure to air..."
