Fixed sexual partners cannot get AIDS if the other person does not have AIDS. AIDS is a contagious disease that requires a source of infection. Generally speaking, the chances of contracting AIDS are higher during sexual contact with AIDS patients, especially unprotected sex. Patients with AIDS need timely antiviral treatment. Generally, after antiviral treatment, the number of viruses will gradually decrease, and the infectiousness will be significantly reduced. For normal people, the most important thing to prevent HIV is to be clean and have a regular sexual partner. If you have sex, it is recommended that you wear condoms to prevent sexually transmitted diseases, including AIDS.
