A woman has been infected with the novel coronavirus after returning from Wuhan, bringing the tally to 109 which includes a suspected case.

The head of the communicable disease branch of the Centre for Health Protection, Dr. Chuang Shuk-kwan, said the 108th case is a 38-year-old woman who returned from Hubei on the fourth charter flight arranged by the SAR government last week.

The woman was the first confirmed case among those being sent back from Wuhan.

In the daily press conference, Chuang said the woman traveled to Wuhan to visit her relatives in mid-January and had been staying at her family's place until being sent back to Hong Kong.

But Chuang said the risk of infections for other people on the flight was “very low”.

Four flights were sent by the SAR government to send Hongkongers stranded in the epicenter of the outbreak home, airlifting a total of 535 people, including Secretary for Constitutional and Mainland Affairs Nip Tak-kuen.

The people sent back were placed under mandatory quarantine for 14 days in Chun Yeung Estate in Fotan upon arrival.

Meanwhile, the 108th case, the husband of the 105th case, has also been diagnosed with the virus yesterday night. He displayed no symptoms when sent to the hospital from one of the quarantine centers. The couple was believed to have been infected while visiting India with other 18 people on a travel group last month.

The man was asymptomatic and had mainly stayed at home recently, so not many close contacts would need to be traced.

The man was the fourth participant in the travel group to India confirmed with the virus in Hong Kong, with an additional case of a 80-year-old woman in British Columbia.

Another participant of the group, a 73-year-old woman, was listed as a suspected case. Her samples showed different results when being tested in Hong Kong Sanatorium and Hospital and Queen Mary Hospital, and thus requires further testing.

Officials said the remaining participants of the travel group who returned to Hong Kong would be sent to quarantine centers, while the other 8 participants were in Canada and the United Kingdom.

The woman joined the travel group on February 4 but early left on 19 February.

Meanwhile, officials said health authorities in South Korea had informed the SAR government that a man who recently traveled on two Cathay Pacific flights has tested positive.

The man, 22, was on the flight CX288 from Frankfurt to Hong Kong on February 28, and another flight CX438 from Hong Kong to Incheon in February 29.

He had fallen ill the day before he took the first flight.

Officials said anyone who took the two Cathay flights should contact them.
