Top epidemiologist warns what Sydney's Covid-19 outbreak means for New Zealand

As Australian health officials scramble to contain the Covid-19 outbreak in Sydney, a top epidemiologist here is warning 'that could be us'. Professor Michael Baker says New Zealand is arguably entering 'our most dangerous stage' since the August Auckland outbreak as the pandemic surges in the Northern Hemisphere. Baker, from the University of Otago's school of public health, is now calling for returnees from countries where the virus is 'out of control' to take an additional step and isolate under supervision at a hotel and be tested before even stepping on the plane.
