Ship's last HK passenger back home

The Security Bureau today said that the last Hong Kong resident who had contracted COVID-19 while aboard the Diamond Princess cruise ship and was hospitalised in Japan has returned to Hong Kong.

 

Immigration Department staff that assisted Hong Kong residents in Japan have completed their mission and returned to Hong Kong as well.

 

In early February, a cluster of COVID-19 infection cases occurred on the Diamond Princess cruise docked in Yokohama.

 

Of some 3,700 passengers and crew, about 370 were from Hong Kong. The 712 confirmed COVID-19 cases associated with the cruise included 76 Hong Kong residents who were hospitalised in Japan for isolation and treatment.

 

While three Hong Kong residents passed away, the remaining 73 patients returned to Hong Kong or their places of residence after being discharged from the hospital.

 

As for other Hong Kong residents on the cruise, the bureau noted that the Hong Kong Special Administrative Region Government arranged three flights, between February 19 and 23, to escort 193 of them back to the city.

 

Upon arrival, they were transferred to the quarantine centre at Chun Yeung Estate to undergo 14 days of quarantine.

 

Another 144 Hong Kong residents returned on their own via other flights, including 25 close contacts of the patients who had completed quarantine in Japan.

 

For those who returned to Hong Kong on their own and did not complete 14 days of quarantine in Japan, they were required to complete the remaining quarantine period at a quarantine centre.

 

Of the 231 cruise passengers admitted to the quarantine centre at Chun Yeung Estate, nine tested positive for COVID-19 and were sent to hospitals for isolation and treatment.

 

The Hong Kong SAR Government expressed profound condolences on the passing of the Hong Kong patients and its deepest sympathies to their families.

 

The SAR Government emphasised that the incident could not have been resolved smoothly without the staunch support of the Office of the Commissioner of the Ministry of Foreign Affairs of the People's Republic of China in the Hong Kong Special Administrative Region, the Embassy of the People’s Republic of China in Japan and Japanese authorities.

 

The SAR Government also thanked Cathay Pacific Airways and the Airport Authority for their assistance, the bureau added.
