Jilin, the second largest city in northeast China's Jilin Province, will close all private clinics and hospital outpatient services from Sunday, local authorities announced Saturday.

Patients seeking medical help will need to visit medical institutions and those with a fever should go to fever clinics, according to the announcement.

Local law enforcement personnel are ordered to immediately start inspecting the city's private clinics to ensure they follow epidemic control measures. Clinics will be closed until further notice from the local government.

Jilin City reported six new COVID-19 cases on Tuesday, and all of them could be traced directly to one confirmed case in Shulan City, where an infection cluster was previously detected.
