Hangzhou has seen its number of confirmed novel coronavirus pneumonia cases decline and the number of successful recoveries rise over the past few days.

According to statistics released by the local health commission, as of Feb 11, the total number of reported pneumonia cases throughout the city was 159, with the number of cases confirmed on Feb 11 being two.

Officials said that this was the sixth day in a row that the rise in confirmed cases had remained in the single digits.

The application of big data technology has proved effective in helping prevent and control the epidemic.

The city is using the so-called City Brain platform to analyze big data collected from 80 sources to build a model of the population susceptible to infection and target patients and their contacts.

The grid management pattern has also proved useful in preventing and controlling infection, and a large number of community workers in Hangzhou are now playing an important role in organizing patients and helping with quarantine management.

In Xiacheng district, thousands of volunteers have become involved in the fight against the virus. They work in shifts to ensure there are people on duty around the clock.

One volunteer, Liu Guofang, has been working for the past 15 days. She has refused to rest even when ordered to do so.

“Our duty is to verify the personal information of residents, examine their health, and tell them how to avoid infection,” Liu said.

Hangzhou has also adopted a health QR code system. Residents and those entering the city need to apply online and receive either a green, red, or yellow code. The colors are based on health information provided by the applicants.

Those who plan to enter Hangzhou need to obtain a green code, and only those with green codes may travel around the city. Those with red or yellow codes must first undergo seven to 14 days of quarantine.
