The number of AIDS cases in our country is rising every year. According to conservative estimates, the number of AIDS cases in our country is over 800,000, and the number of new cases is increasing every year. AIDS is a disease that can be prevented and controlled. The main way of transmission of AIDS is through extramarital sex, followed by blood transmission, and then mother-to-child transmission. The key to prevention is to interrupt sexual transmission. For HIV carriers, timely and standardized anti-HIV treatment can also reduce infectiousness. Now the state is free of charge for all patients with AIDS antiviral treatment.
