HONG KONG - Hong Kong reported 11 new COVID-19 cases on Monday, ending a three-day streak of single-digit increases.

In a media briefing on Monday afternoon, said Chuang Shuk-kwan, head of the communicable disease branch of the Centre for Health Protection said the new cases included four local infections and seven imported cases. The local tally of confirmed cases reached 5,124.

The four local infections included that of a 46-year-old woman who lived in Tsing Yi and worked in Kwai Chung

Chuang said the seven imported cases included six persons flying back on the same Nepal Airlines flight from Kathmandu on Oct 3 and one patient who returned from India. The Nepal Airlines flight would be suspended for two weeks.

The four local infections included that of a 46-year-old woman who lived in Tsing Yi and worked in Kwai Chung. The source of her infection is unknown, Chuang said.

The three other local cases were all linked to previous infections, she added.

Meanwhile, public health experts called for continued efforts to fight the COVID-19 epidemic and urged people not to let their guard down as new cases continued to be reported amid a relaxing of social distancing measures.

During the just-finished four-day holiday, public places from restaurants to bars were packed by people as the Hong Kong Special Administrative Region (HKSAR) government loosened restrictions over entertainment venues due to an abating epidemic situation.

Ko Wing-man, former secretary for food and health of the HKSAR government, said people should stay alert as the anti-epidemic work will become more difficult in winter if COVID-19 lingers and the seasonal flu also starts to spread in Hong Kong.

David Hui, a respiratory medicine expert at the Chinese University of Hong Kong, warned of a fourth wave of the epidemic as more people have started to participate in social activities.

The government should step up supervision over gray zones, such as some bars, to contain a potential rebound in new infections, said Leung Chi-chiu, chairman of the Hong Kong Medical Association's Advisory Committee on Communicable Diseases.

As of Monday, there were 117 coronavirus patients being treated in hospitals, with 11 in critical condition.
