When AIDS is controlled and stabilized, it does not necessarily mean that it is no longer contagious. The main treatment for AIDS is antiviral therapy, through which the replication of the virus in the body can be suppressed. After suppressing the replication of the virus, the infectiousness of the patient will be significantly reduced. After antiretroviral treatment, the patient’s viral load is lower than the lower limit of detection, and the condition is controlled and stabilized, but it is not absolutely free of contagiousness. HIV viral load is lower than the lower limit of detection does not mean that there is no HIV in the body, only due to technical reasons, the accuracy of the instrument can not detect the virus, even if the blood can not detect the virus, semen, vaginal secretions, lymphatic tissues may have the virus, although greatly reducing the probability of transmission of AIDS, but there is also the possibility of transmission. It is very likely that the antiviral drugs for HIV will become resistant to the drugs in the course of treatment, and once resistance occurs, the virus can replicate again and cause a rebound, thus causing infection. To be on the safe side, you should try to avoid high-risk contact, and if you want to have sex, it is recommended that you use condoms throughout the entire process to avoid accidents that could lead to infection in your spouse.
