DAB chairwoman Starry Lee said on Monday that she thinks the government adopted all the anti-epidemic measures possible relating to celebrations marking the July 1 anniversary, and the Covid infections that emerged were "unpredictable".
Party members Tam Yiu-chung and Steven Ho came down with Covid, and Ho was at one of the events that President Xi Jinping attended last Thursday.
"You know, Hong Kong has 2,000 infections [a day], right? Do you think there's no risk? I think there's always risk," Lee told reporters.
"But I would appreciate what the government had done regarding the prevention measures taken for the ceremony on July 1 and before. I think they had tried their best."
Lee noted that all event attendees were wearing N95 masks, and there was a marked distance between President Xi and Ho during the photo-taking session.
Lee added that the DAB is hosting a reception on Tuesday afternoon to celebrate the party's 30th anniversary, and Chief Executive John Lee will be among those attending.
The party chairwoman also said the most urgent priority for Lee's administration is to work out its anti-Covid measures and border-reopening arrangements with the mainland and overseas.
