SA Health authorities have confirmed five new cases of COVID-19 in South Australia.

The state’s chief public health officer Dr Nicola Spurrier confirmed the news in a press conference this afternoon, telling reporters: “Unfortunately, we have some more cases to report today.”

Of the five new cases, Dr Spurrier confirmed that four have been confirmed as linked to the growing Parafield cluster.

The other case is still being investigated as of this afternoon.

Three of the reported cases are family members of a security guard at one of the city’s medi-hotels.

Premier Steven Marshall kicked off the press conference by congratulating the state’s response to the cluster, but warned that there is still work to do.

“We are not out of the woods yet, we are just at the beginning stages of dealing with this particular very nasty cluster,” Mr Marshall said.

The Premier also confirmed that there had been over 6,000 people tested in the state on Tuesday, and a further 5,000 on Monday.

Around 4,000 close contacts are now in quarantine around Adelaide.

The five new, confirmed cases brings the total size of the Parafield cluster to 20, however, that is expected to grow in the coming days.

Prof Spurrier flagged 14 suspected cases of the virus which are currently being investigated or awaiting test results.
