The main measure to prevent AIDS is, most importantly, to strengthen the publicity and education on AIDS prevention and control and to inform the public of the seriousness of AIDS. High-risk groups should use condoms, and blood and blood products should be strictly screened and used only under the guidance of a regular hospital and doctor if necessary. Avoid using disposable syringes and unsterilized medical devices with others, and prohibit any form of drug use. Standardized treatment of STDs, obstetric interventions, antiviral drug interventions and artificial feeding can be used for HIV-infected pregnant women to prevent HIV transmission to their babies. Pay attention to personal hygiene and do not share hygiene items with others, such as toothbrushes and razors.
