Health bosses are scrambling to find Sydney's 'missing link' Covid-19 case, warning the virus is still being transmitted 'unrecognised' across the city.
NSW chief health officer Dr Kerry Chant revealed Monday's infection figures were 'not concerning', pointing to another day of zero transmission.
But she warned that the virus could still be circulating in the community without people realising.
'(The local case's) contact with the infectious person must have been very fleeting,' Dr Chant said on Monday.
'We are concerned there are chains of transmission in the community that are unrecognised.
'We're not out of the risk period.'
