Organ transplants do not contract AIDS because the donor will be thoroughly examined before the organ transplant to exclude all infectious diseases of the patient, such as hepatitis B, syphilis, hepatitis C, AIDS, etc. Only if the patient does not have these infectious diseases will the organ transplant be possible. If the patient has an infectious disease, none of his organs can be transplanted. Therefore, organ transplants do not infect with AIDS and there is no need to worry. AIDS is transmitted in three main ways: sexual transmission, blood transmission, and mother-to-child transmission. If an ordinary person wants to prevent HIV infection, he or she should insist on cleanliness, keep regular sexual partners, and avoid sharing personal items such as toothbrushes, razors, and shavers with others.
