Short answer: possibly.
First of all, to contract AIDS, the person must be infected with the HIV virus. If the person is infected with the HIV virus (which causes aids) and you get their blood on an open wound, or a mucus membrane such as the mouth, it is possible. If you get some infected blood on normal skin that is healthy, the chances of you contracting the HIV virus are slim to impossible (?).
if u have an open cut and you touch someone's blood and it gets in ur cut...infection
no, when aids gets in the air it dies after a few seconds, and will certainly be killed off after being heated in an oven.
No they can not.
aids can be sexually transmitted but you can also catch it from the blood of a person infected by aids (hiv)
it depends on the ratio of blood to water. more blood= higher chance. if its all blood it is extremely likely
AIDS is an STD, which can only be transferred by blood and body fluids. So if that nail has blood on it, yes.
well i think that people in Africa had ceremonies where they drank monkeys blood. they came back to the USA and i think that there were 2 ways to get aids off someone else. It was a blood infection so sleeping with someone that had a different blood type and being born from somene who had aids
no u cant, only if the person with aids has a cut in there mouth. then the blood will go into the healthy person.

AIDS is a development of HIV which is transmitted by blood or mucous membrane contact. Most of the time, AIDS is caught from sexual interaction with someone who has the disease.
That would be possible, although improbable. But it's a rather far-fetched scenario.
If someone is AIDS free and happens to swallow say saliva with blood samples of an infected person, he or she cannot contact HIV unless if he or she has a sore throat.
