Pressure is mounting on already strained ties between the Hong Kong government and residents as fears over the growing Wuhan virus outbreak continue to heighten and divide the community.
Trade unions in the city representing hospital and rail workers, among others, are threatening strikes - a move to pressure the government into shutting all borders with mainland China to stop the spread of the virus.
Pan-democracy district councillors have slammed measures rolled out by Hong Kong leader Carrie Lam as inadequate, urging the government to fully seal all borders to mainland visitors. They said full closure of all borders would deter the spread of the virus and reduce the workload of hospital staff.
Yesterday, pro-Beijing lawmaker and executive councillor Regina Ip urged the government to temporarily stop all mainland tourists from coming into Hong Kong.
"Although the mainland authorities have already announced they will stop issuing individual visit permits (to Hong Kong), the government should talk to the mainland authorities to stop allowing them to enter," she said.
The Chief Executive had announced on Tuesday that all cross-border rail routes between the mainland and Hong Kong would be suspended starting from midnight yesterday. Services at six of 14 border checkpoints would be stopped to prevent further spread of the virus, along with the high-speed rail line and the original rail line to Guangzhou.
Four local airlines - Cathay Pacific Airways, Hong Kong Airlines, Cathay Dragon and Hong Kong Express - halved flights between Hong Kong and 24 mainland cities to about 240 flights weekly from yesterday.
Since midnight on Monday, Hong Kong has banned the entry of people from the Chinese province of Hubei, whose capital Wuhan is at the epicentre of the outbreak.
As of Wednesday night, some 1,600 people from Hubei had been turned away by the immigration authorities. This did not apply to returning Hong Kong residents.
Associate Professor Sing Ming of the Hong Kong University of Science and Technology believes that the outbreak will "definitely" further undermine the already fragile public confidence in the Hong Kong government.
There is widespread perception that the government has been too sluggish to counter the outbreak and the spread of the virus, he said.
"(There has been a) series of blunders and misgovernance on the part of Hong Kong, and the widespread perception that Beijing has been interfering with the measures that the Hong Kong government can adopt to counter the epidemic.
"I think these will only strengthen the determination of some of the Hong Kong people, including the middle class, to emigrate out of Hong Kong in the medium to long run, and that would be a very important hit to Hong Kong's long-term vitality in both the economic and social sense," said Prof Sing.
Associate Professor Alfred Wu of the Lee Kuan Yew School of Public Policy thinks the pro-democracy demonstrations that have gripped the city for over seven months will go on despite worries over the spread of the new coronavirus.
He pointed out that the root causes of the political crisis remain, and the outbreak may temporarily stop people from gathering, but not for long.
Asked if the government can turn the current situation around to its favour, Prof Wu said that hinges on the government's action or inaction.
"Mistrust between the government and the public could worsen due to different reasons. (As it is) some people have questioned the government's transparency in handling the situation," he said.
With the severe acute respiratory syndrome (Sars) outbreak in 2003 still fresh in people's minds, long queues formed outside pharmacies yesterday morning as residents rushed to get limited supplies of surgical masks.
At different shops in the city, including Kowloon Tong, Tin Shui Wai and Tseung Kwan O, thousands waited for hours to get their hands on the limited packets of masks on offer, leaving many disappointed and angry.
Concerns about the virus prompted shoppers to sweep not just surgical masks, disinfectant wipes and hand sanitisers off the shelves, but also instant noodles and frozen food as people started hoarding supplies.
As of Wednesday, the Hong Kong authorities had confirmed 10 cases of the Wuhan coronavirus.
