The Centre for Health Protection today said a team will be sent to a building in Fu Heng Estate in Tai Po to investigate the cause of a new COVID-19 infection.

The centre’s Communicable Disease Branch Head Dr Chuang Shuk-kwan made the statement at a press briefing this afternoon.

Dr Chuang explained that the 59-year-old man who tested positive for the virus lives in the same building where two people were confirmed to be infected with the disease earlier this month.

She said: “We would like to go to the site to see because there are other possibilities, for example, whether they know each other but we understand not, and they may have shared the same lift or they may have just passed each other.

“The only thing we worry about is that they live in flats of the same direction. That’s why we want to check whether there are other environmental factors, for example the pipes, and other things that may explain the illness.”

She added that any further actions will depend on the site visit.

The centre is also investigating three new cases involving patients with recent travel history.

One of them is a 39-year-old woman who lives alone in Cornell Centre in Chai Wan.

She developed a runny and blocked nose since March 12 and attended the Hong Kong Sanitorium & Hospital and then was transferred to Ruttonjee Hospital on March 13. She is now in a stable condition.

The patient travelled to Dubai, United Arab Emirates, between February 26 and 29 and visited Madrid, Spain, from February 29 to March 10.

She took Emirates flight EK142 from Madrid to Dubai on March 10 and then departed Dubai on Emirates flight EK380 arriving in Hong Kong on March 11.

Another case involves a 28-year-old woman who lives alone in 684 Clear Water Bay Road.

She developed a fever and cough since March 12 and attended the Accident & Emergency Department at Tseung Kwan O Hospital on the same day.

She is now in a stable condition and has been brought to United Christian Hospital for management.

The patient resides in London in the UK. She returned to Hong Kong from London via British Airways flight BA31 on March 11.

The third case involves a 59-year-old man who is the brother-in-law of the 54-year-old female patient confirmed on March 13.

The patient with underlying illness lives in Tivoli Garden, Tsing Yi. He developed diarrhoea since March 2, shortness of breath and sore throat on March 10 and fever from March 12.

He was admitted to Princess Margaret Hospital for treatment during contact tracing by the centre on March 13.

The patient travelled to Morocco between February 27 and March 8.

On March 8, he took Transavia flight HV5760 with his sister-in-law from Morocco to Amsterdam in the Netherlands and then departed Amsterdam on KLM Royal Dutch Airlines flight KL887 arriving in Hong Kong on March 9.

The patient's daughter-in-law, grandson and domestic helper who live with him are asymptomatic and have been arranged for quarantine.
