A new confirmed case of COVID-19 linked to a growing South Australian cluster has forced 70 close contacts into a medi-hotel for quarantine, while 1,100 casual contacts are required to isolate for just over a week.
The new case has also forced adult education facility Thebarton Senior College to close as the cluster associated with the school grows to five.
The 70 close contacts will be moved into medi-hotels that have traditionally been used for returning international travellers.
Despite the harsh measures imposed on these individuals, with eight active cases currently in South Australia the state's chief public health officer Nicola Spurrier has advised the public not to panic.
"We have not got community transmission in South Australia in any way in a widespread form and this is why we're being absolutely over-cautious in this instance," she said.
"There are a large number of close contacts and this is because the Thebarton Senior College is a college for adult learners."
This growing cluster, dubbed by health authorities as the Thebarton Cluster, was linked to a 20-year-old returning essential worker who was self-isolating at the Walkers Arms Hotel.
He then passed the virus on to a cleaner and another woman in her 20s which has sparked this outbreak.
A new drive-through COVID-19 testing location has opened in Aldinga at the GP Plus Health Care Centre.
