On Monday, the province reported four confirmed cases. Two of them are villagers from Gaocheng district, Shijiazhuang, capital of Hebei. Both of them, in their 50s, didn't leave their villages for most of the past week until their symptoms worsened and they went to local clinics.

Hospitals in Shijiazhuang have tightened measures for COVID-19 prevention and control. All newly admitted patients and any caregivers should have two negative nucleic acid test results before entering wards, the Second Hospital of Hebei Medical University said on Monday

The other two are brothers in their 30s from Nangong of the city of Xingtai, who both visited hospitals several days before they tested positive. The wife of the elder brother is an asymptomatic carrier.

To contain the risk of spread, all villages and communities where the four patients live became medium-risk areas starting on Monday.

For targeted intervention, the county-level city of Nangong has started nucleic acid tests for all of its around 500,000 residents. "Don't go out of or into the city if not necessary," the city's anti-virus unit said.

Gaocheng district is known for producing lanterns that are widely used for celebrating Spring Festival, which is on Feb 12 this year.

"Most would-be buyers for our lanterns have canceled their orders due to the new outbreak," said Zhang Fengjun, chairman of local lantern maker Gaocheng Palace Lantern Design and Development Centre Co. "I'm afraid some events might be canceled to reduce transmission risks, like last year."

Besides Hebei province, the country reported nine new local confirmed COVID-19 cases on Monday－two in Beijing, six in Liaoning province and one in Heilongjiang province.

Dalian in Liaoning is conducting stricter quarantine measures after it found some new cases that had a long latency period and spread quickly.

Tang Yi, head of the city's bureau of civil affairs, said on Monday that some cases tested positive after having six or 11 virus tests.

Those who are required to quarantine at home should stay in quarantine for at least 21 days, and receive four tests－one on the first day of quarantine, and then on the seventh, 13th and 20th days, Tang said.
