It's a technique in parenteral medication used frequently in intramuscular sites. Holding the syringe upright, the administrator of the medication aspirates around 0.2ml to 0.3mL of air in order to clear out any medication that may be left inside the needle. They usually change the needle after this so that no solution of the medication remains outside the needle shaft. Injection of the needle is done at 90 degrees so that all of the air you aspirated should be the LAST to exit the syringe, creating an air lock inside the skin.
Active virus is technically parasitic in nature and lie dormant until a host is present so they can reproduce. Active bacterium are present in the air and most are even good. Bacteria is already alive and reproducing.
by a virus or by a virus in the air
A virus that can survive to infect others through the air is called an airborne virus.
Influenza is an air-borne virus.
To effectively remove air from a basketball, insert a needle into the air valve and press down on the needle to release the air. Repeat this process until the desired amount of air is removed.

oxygen and moisture
They need air to form, so if they go too high then there's not enough.
The odds of HIV transmitting through such a scenario is extremely unlikely. Because of the frailty of the virus, any exposure to air will break the virus down within minutes. There is some debate that in a vessel such as a needle, it may be possible for the virus to stay intact for longer, due to blood in the needle being minimally exposed to air. However because HIV will also die in temperatures deviating more than 3 or 4 degrees from the human norm, even if the HIV virus were to escape death through air exposure, temperature will kill it shortly. Thus even HIV in needles will not be able to survive for more than perhaps 10 minutes. So while it is technically plausible for such a scenario to happen, the window of opportunity is extremely small and thus extremely unlikely.
