Does HIV/AIDS die after contact with air? Ie, spilled blood on floor etc..?!
Question: I just wanted to know if it is true that if blood or whatever secretion is exposed to air for a period of time, if the antibodies die?
Is it less likely to catch AIDS/HIV after touching blood etc after its been exposed to air for a period of time?

HIV, the virus responsible for AIDS, is an enveloped virus. That means it's surrounded by a lipid membrane. In other words, it's wearing a coat of the same material that surrounds living cells. That's sturdy enough inside a
body, but not outside in the rest of the world. If the virus should be coughed into the air, or spilled onto a surface like a toilet seat, it would not survive long enough to infect anybody.
The HIV virus is actually quite fragile and can't live long at all outside a host white blood cell. It is easily disinfected and doesn't live on inanimate objects and can't be carried by the
air. The only way to get HIV is for an infected white blood cell from one host to be directly deposited into the bloodstream of another host.
If the disease were easier to transmit, we'd be in big
trouble.

This was considered heavily about the time AIDS became a National problem. People with Aids were rejected from restaurants etc.
The Aids virus does in fact die after a certain period so not to worry anyone.
The longer HIV is exposed outside the body, the more unlikely it is to live. And we're not concerned with the transmission of antibodies but the actual virus.
For instance, a small amount of blood on an open, cool floor would probably die within seconds. This is not the the environment that HIV survives in. Another example might be a larger amount of blood in a warm small space, the virus might live for minutes. Blood splashes, which occur primarily in a healthcare settings, require all the right circumstances for transmission, such as a splash right to an open wound or a needle stick-drawing blood from an infected person and immediately getting stuck with the needle.
Bacteria, such as Hepatitis and TB have been said to live on a table for days. These experiments were probably controlled as in conducted by laboratory personnel so that may or may not have made a difference.
In general, any virus or bacteria, needs a warm (body temperate), moist (as in fluid), dark environment to survive any extended length of time.
the virus is very weak outside the human host ,and fragile it dies in room temperature 25 degree celsius
