A normal person can live with an AIDS patient because living with an AIDS patient does not transmit AIDS. Even kissing or sharing a meal with an AIDS patient is not contagious. In fact, most behaviors are not contagious, such as sharing toilets, showers, office equipment, telephones, swimming in a pool, hugging and shaking hands with an AIDS patient. Since AIDS is transmitted through blood, sex and mother-to-child transmission, you can protect yourself from HIV infection by avoiding contact with the blood and body fluids of AIDS patients and by using a condom when having sex with them.
