Do you need a physical examination for tuberculosis when you study in the UK during the epidemic?

If the course of disease is less than 6 months, there is no need to do a tuberculosis physical examination, if the course of disease is more than 6 months, there is a need to do a tuberculosis physical examination. Students who have already studied in the UK do not need to have a tuberculosis physical examination if they have not been away from the UK for more than 6 months when they renew their visas or apply for visas again when they return to China. /zd/xx
