The Victorian government does not know where almost 1,600 Covid-19 infections among healthcare workers - almost 85% of such cases - were acquired, according to an email seen by Guardian Australia.

A message sent to health workers by the peak Victorian authority for safety improvement in healthcare says it is still examining the source of the majority of infections, calling into question claims from the state's premier, Daniel Andrews, and health minister, Jenny Mikakos, that most workers were infected in the community.
