During the Middle Ages, particularly around the 14th century during the Black Death, people believed that diseases could be transmitted through "miasma," or bad air. This theory held that foul odors from infected individuals or decaying matter could spread illness simply by being inhaled. This belief persisted for centuries until the development of germ theory in the 19th century, which established that diseases are caused by microorganisms rather than miasma.

You don't actually "get" AIDS. You might get infected with HIV, and later you might develop AIDS. You can get infected with HIV from anyone who's infected, even if they don't look sick and even if they haven't tested HIV-positive yet. The blood, vaginal fluid, semen, and breast milk of people infected with HIV has enough of the virus in it to infect other people. Most people get the HIV virus by: * having sex with an infected person * sharing a needle (shooting drugs) with someone who's infected * being born when their mother is infected, or drinking the breast milk of an infected woman Getting a transfusion of infected blood used to be a way people got AIDS, but now the blood supply is screened very carefully and the risk is extremely low.
