Most were migrant farmer worker at age of 20 - 40 years old. Condusions Primary screening test in laboratories for HIV infection in various populations enhances identification of HIV infected persons. However, confirmation of HIV infection relies on WB. We should strengthen HIV antibody detection in various populations, and especially intensify management and HIV antibody detection of migrant farmer workers so as to detect more HIV - infected persons and promote control of HIV spreading.
