If you are afraid of being infected with HIV, you need to be proactive in prevention and your own protection. To do a good job, it is important to understand how HIV is transmitted. HIV is transmitted sexually, through blood transmission, and vertically from mother to child. Normal daily contact will not infect you with HIV. It is important to be clean and learn to be faithful and have a regular sexual partner. When having unclean sexual relations, make sure to wear condoms throughout, which can effectively block HIV infection. Do not take drugs and do not share a syringe with others. Use separate utensils in your life, including razors and shavers. If you have unclean sex without a condom or are exposed to HIV, be sure to go to a regular hospital for examination and early and aggressive intervention.
