13 untraceable cases among 63 new virus infections in HK

There were also more than 30 people who tested preliminarily positive on Tuesday, according to Chuang, who said she was cautiously optimistic about a downward trend, hoping that there will not be a rebound.

New cases continued to be detected in the city's residential buildings. Kwun Tong Garden Estate Lotus Towers had seven cases while Yau Mei Court Yun Mei House in Yau Tong had four infections, Chuang said.

Health authorities will distribute specimen collection bottles to residents of these two buildings, she added.

Chuang said two preliminarily positive patients were also recorded at Ping Tin Estate Ping Shing in Lam Tin.

At least four confirmed cases had been detected here previously. Residents will be subject to mandatory testing after the two new cases are confirmed.
