Living together is generally not contagious because the AIDS virus is mainly found in the blood, vaginal secretions, semen, cerebrospinal fluid, pleural and abdominal fluid, breast milk, amniotic fluid and other bodily fluids of the infectious agent, and it is mainly transmitted through sexual contact, the blood pathway, or vertical transmission from mother to child, and it is not contagious through general contact, such as hugging, shaking hands, and so on. If you live with someone who has AIDS, you should pay attention to the division of personal belongings, and should not share toothbrushes, razors, shavers, razors, etc., so as not to infect AIDS through broken skin. In addition, if you have sexual contact with an AIDS patient, you should wear a condom. Wearing a condom correctly is an effective way to stop the spread of AIDS during sex.
