Sydney virus cases transmitted during quarantine raise concerns

Concerns in Australia about Covid-19 spreading in quarantine are mounting as three new cases among a family of returned travelers were discovered to have been transmitted in a Sydney hotel.

The infections, initially recorded as contracted overseas, are now believed to have been picked up from a family of four in an adjoining room in a city quarantine hotel, New South Wales Health said in a statement Sunday. Investigations into how the transmission occurred are under way, it said. "All guests staying on the same floor of the hotel have been retested and returned negative results,” and staff who worked nearby are self-isolating and getting tests, New South Wales Health said.
