Hong Kong authorities have activated a newly created “serious response” level as fears spread about a mysterious infectious disease that may have been brought back by visitors to a mainland Chinese city.
The serious response level indicates a moderate impact on Hong Kong’s population of 7.5 million people.
It is the second highest in a three-tier system that is part of a new government plan launched on Saturday to respond to infectious diseases of unknown cause.
The city’s health department added an additional thermal imaging system at Hong Kong’s airport on Friday to check the body temperature of arriving passengers. More staff have been assigned for temperature checks at the West Kowloon high-speed rail station that connects Hong Kong to the mainland.
The territory's embattled chief executive Carrie Lam, on a visit to the train station Friday to review the health surveillance measures, urged any travellers who develop respiratory symptoms to wear surgical masks, seek medical attention and let doctors know where they have been.
The Wuhan health commission said 11 of the 44 people diagnosed with the pneumonia were in critical condition as of Friday. All were being treated in isolation and 121 others who had been in close contact with them were under observation.
Most of the cases have been traced to the South China Seafood City food market in the suburbs of sprawling Wuhan, where offerings reportedly include wild animals that can carry viruses dangerous to humans. The commission said the market has been disinfected.
The most common symptom has been fever, with shortness of breath and lung infections in a small number of cases, the commission said.
There have been no clear indications of human-to-human transmission of the disease.
The latest cases in Hong Kong are two females, aged 12 and 41, who had been to Wuhan in the past 14 days but did not appear to have visited the food market, the Hospital Authority said. They were in stable condition and being treated in isolation at Princess Margaret Hospital.
