The total number of cases from an unknown source in the past 14 days (October 25 to November 7, 2020) is one for metropolitan Melbourne and zero for regional Victoria. The 14-day period for the collection data source ends 48 hours earlier than the 14-day period used to calculate the new case average because it takes time to fully investigate a case and assign its collection type.
The Department of Health and Human Services is working closely with South Australian health officials to investigate an Australia-based resident who has worked in Victoria and who tested positive for coronavirus in South Australia.
The case is a geriatric nurse who previously tested positive in Victoria in early August and was isolated for the entire required period. They recovered and were cleared of the virus later that month. The case has not worked in elderly care since mid-October.
The case tested positive on November 9 in South Australia as part of the immigration screening process. The case shows no symptoms.
It is likely that the case will constitute a temporary elimination after a previous infection, but with great caution, and while further investigation is conducted, the public health response in the two jurisdictions will converge. For this reason, we are currently asking people who visited Melbourne Central on November 8th between 2:00 pm and 5:00 pm or who were at Terminal 4 at Melbourne Airport on November 9th between 12:00 pm and 1:00 pm to be alert to the mildest symptoms and to search immediately Testing to see if they are uncomfortable.
