For the total number of confirmed cases in Australia, this table shows the source of infection as a percentage.
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 – contact with a confirmed case – the person was infected in Australia through contact with someone confirmed to have COVID-19
- locally acquired – contact not identified – the person was infected in Australia, but the source of infection is not known
- 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 mid-June have been locally 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.
