COVID restrictions return to Sydney as mystery case investigated

Australian authorities trying to work out how a Sydney man acquired Indian virus variant linked to a case from the US

Social-distancing measures have been imposed across greater Sydney, Australia’s biggest city, as officials scrambled to find out how a 50-year-old resident had been infected with an Indian variant of the COVID-19 virus. The man was diagnosed with the coronavirus on Wednesday and also passed the disease to his wife but health officials are baffled by the case because the man has no known links to high-risk jobs or people. With many people expected to get together over the weekend to celebrate Mother’s Day, the New South Wales state government moved quickly on Thursday to restrict the size of gatherings and mandate masks on public transport and at indoor events.
