Description: 

This table shows the number of COVID-19 cases by source of infection for each state and territory, since the first case was reported. The table also shows the total number of cases and deaths by state and territory.

The source of infection for confirmed cases of COVID-19 can be described as:

  • overseas acquired – the person was infected while overseas (including at sea)
  • locally acquired – known contact – the person was infected in Australia through contact with someone confirmed to have COVID-19
  • locally acquired – unknown contact – the person was infected in Australia, but the source of infection is not known
  • locally acquired –interstate travel – the person was infected in Australia, but not in the reporting jurisdiction
  • under investigation – the source of infection has not yet been determined, but is currently being investigated through public health actions.

The majority of confirmed cases since late October have been overseas acquired.

The number of cases currently under investigation should ideally be as low as possible.

Knowing the source of infection assists in stopping the spread of COVID-19.

A COVID-19 death is defined for surveillance purposes as a death in a probable or confirmed COVID-19 case, unless there is a clear alternative cause of death that cannot be related to COVID19 (e.g. trauma). There should be no period of complete recovery from COVID-19 between illness and death. Where a Coroner’s report is available, these findings are to be observed.
