Lanzhou city in Northwest China's Gansu Province closed off residential areas citywide on Tuesday to prevent further spread of the recent COVID-19 outbreaks.

According to the announcement published by Lanzhou government, residential areas will strictly control the entry and exit of people during the implementation of the closed-off management. 

Each residential area can leave one entrance gate open in order for residents to access daily needs, pandemic prevention participation and emergency medical treatment. But residents need to measure their body temperature and show the records of certifications including the Health Code, the Trip code, the Passing Code and a COVID-19 vaccination record.

Those undergoing home quarantine and medical observation will be under the management of the police in their community and residential properties. They will have temperature measurement twice a day and regular nucleic acid tests. 

Each community will set up the area for residents to take their packages and takeouts with no direct contact with couriers. Property management staff should disinfect the entrances, cell doorways, elevator cabs and buttons every day.

Lanzhou's closed management follows the lockdown of China-Mongolia border city Ejin Banner, which on Monday asked all residents and tourists in the city to stay indoors to prevent the further spread of COVID-19.

According to the regional health commission, Gansu Province reported a total of 45 locally transmitted confirmed COVID-19 cases from October 18 to October 25, with 33 cases detected in Lanzhou city. 

The latest COVID-19 resurgence, which has spread to 11 provincial-level regions including Gansu Province, was triggered by a new imported source and was diagnosed as the Delta variant, according to officials from China's top health authority on Sunday.
