Normal life will not transmit AIDS, even if you live, dine or work with an AIDS patient, use a toilet or washing machine together, take a shower together or sleep together at night, these behaviors will not infect you with AIDS and there is no need to worry. Only if you have unprotected sex with a person with AIDS, or if you have blood from a person with AIDS into a healthy person, or if you use needles or syringes with a person with AIDS, or if you have indirect contact with the blood of a person with AIDS, you will be infected. Therefore, to prevent HIV infection, it is necessary to be clean, not to engage in prostitution, not to visit prostitutes, to avoid sexual activity outside of marriage, to keep a fixed sexual partner, to strictly prohibit drug use, and not to share personal items such as toothbrushes and razors with others. Try to avoid importing blood or blood products that are not confirmed by the source, and avoid invasive operations.
