VCT refers to the process that people make wise choices about AIDS testing after consultation. This decision must be completely left to the questioner's own choice, and this process is completely confidential.
The main content of VCT is to encourage people who have risky behaviors to take voluntary rather than compulsory AIDS testing, and provide counseling, corresponding support and referral services before and after testing, which can not only find, treat and prevent infections in time, but also provide psychological and emotional support for patients (especially HIV-infected people). Testing with counseling services can also encourage patients to reduce risky behaviors and adopt and maintain safe behaviors. The experience of many countries has proved that VCT is an entry point for intervention, treatment and care of HIV-infected people, and an important means to promote HIV-infected people and AIDS patients to change their risky behaviors and prevent transmission. It has been actively advocated by UNAIDS and carried out in many countries and regions, and achieved good results.
