The semen of male AIDS patients contains HIV virus at high levels, so if you come into direct contact with the semen of male AIDS patients, you may get infected with AIDS. If such patients want to prepare for pregnancy, it is best to do so after adequate antiviral treatment so that the virus turns negative and T-cells return to normal before proceeding, so that a healthy baby may be born. In addition to semen which can transmit AIDS, HIV is present in the blood, vaginal secretions and breast milk of AIDS patients, all of which may cause transmission. Because AIDS cannot be cured yet and there are no drugs or medical treatments that can completely remove the HIV virus from a person’s body or make it dormant, it is still important to prevent infection for AIDS. The following measures can be taken to inhibit the spread of AIDS for the main transmission routes: 1. For blood transmission: In daily life, avoid sharing household items with others, such as eyebrow trimmers, razors, combs, toothbrushes, etc. For medical personnel who have had occupational exposure, pay attention to avoid needle-stick injuries and disposable syringes or surgical instruments should not be reused; 2. For sexual contact transmission: Exposed sexual intercourse can cause direct contact with body fluids, so it is recommended to use condoms during sexual intercourse to avoid direct contact to avoid transmission; 3. For mother-to-child transmission: HIV can be transmitted during pregnancy or breastfeeding to the fetus or The HIV virus can be transmitted to the fetus or baby during pregnancy or breastfeeding. Therefore, it is recommended that women should go to the hospital for pre-conception examination to exclude whether they are HIV carriers or infected before preparing for pregnancy, and if they are HIV carriers or infected, they should carefully consider whether to prepare for pregnancy. If a high-risk situation occurs, anti-HIV drugs should be taken as soon as possible for blockade and active testing should be performed.
