The probability of transmitting AIDS from a single sexual act without safety measures is small, according to the corresponding information, the estimated value is 1 out of 1000 times to be infected. If you have sex repeatedly, or if you have sex for a long period of time, or if you have broken skin or mucous membranes during sex, or if the broken skin or mucous membranes are contaminated with body fluids that contain more toxic amounts of HIV, such as vaginal or seminal secretions, or blood, the likelihood of HIV transmission increases significantly. Therefore, it is important to take precautions related to sexual behavior, take safety measures, or do not have sex with people with AIDS. If you don’t know if the other person has AIDS, you should try not to have sex at this time to ensure that you don’t get infected with AIDS through this route. At present, the main way of transmission of AIDS is mainly through sexual transmission.
