HONG KONG, April 29 (Xinhua) -- Hong Kong's Center for Health Protection (CHP) reported Thursday night the first untraceable local infections of a highly transmissible COVID-19 variant.
A 39-year-old domestic helper and a 10-month baby girl living with her in a residential building of Tung Chung were confirmed to have contracted the N501Y mutant strain of novel coronavirus, the CHP said in a statement.
Given the high transmissibility of the variant, all asymptomatic residents of the building involved will be put under compulsory quarantine.
As the adult patient visited a church in Tsing Yi earlier this month, the CHP will also arrange compulsory quarantine for her close contacts and conduct virus testing for other related people.
With the appearance of the variant in communities, the CHP warned of the severity of the situation and called on the public to get the COVID-19 vaccine as soon as possible. Enditem
