The National Health Commission said Saturday that seven members of a newly-established 60-strong nucleic acid testing team from the mainland will arrive in Hong Kong on Sunday, marking the first batch of mainland professionals to join the anti-epidemic fight here, with more medical personnel and materials available if needed.

Besides, the commission has also set up a panel of six experts from Wuhan to provide technical support for Hong Kong's construction of makeshift hospitals.

While Hong Kong's medical system is approaching its limit, the assistance from the mainland at this critical point will inject a shot of "cardiotonic" into Hong Kong's anti-epidemic fight, Ng Chau-pei, president of the Hong Kong Federation of Trade Unions, said earlier this week.

Echoing Ng, Chan Yung, vice-chairperson of the Democratic Alliance for the Betterment and Progress of Hong Kong, said the mainland has gained a lot of valuable experience in the battle against COVID-19 and the firm support of the central government will be a strong guarantee for Hong Kong to win the fight.

The HKSAR government has introduced several rounds of stringent measures over the past weeks, such as compulsory mask-wearing in all public places, the group gathering limit of two people, and tightened testing and quarantine arrangement for exempted persons such as sea and air crew members.

Meanwhile, due to the current COVID-19 outbreak, the chief executive on Friday announced the postponement of the 2020 Legislative Council General Election of the HKSAR by one year.
