BEIJING, Dec. 8 -- China on Thursday rolled out a scheme to guide those in need on how to properly take a COVID-19 antigen self-test, including people who want to take a test, those who work in crowded places and the elderly.

The circular, released by the State Council joint prevention and control mechanism against COVID-19, said that people who test positive with the antigen kits can isolate at home and take appropriate drugs for treatment, if they are asymptomatic or show mild symptoms.

If their condition worsens, they should go to fever clinics at medical institutions for treatment with the assistance of community health workers.
