A group of tourists in the Barossa Valley are in quarantine after testing positive for Coronavirus.
SA Health confirmed on Saturday afternoon that a group of 18 Americans were in quarantine after 10 members of the party returned positive tests the night prior.
Of the 18, four returned negative results while the remaining four were waiting for results to come back.
Chief Public Health Officer Nicola Spurrier fronted a press conference on Saturday to make the announcement.
She said the group immediately self-isolated and requested medical attention once symptoms started to show.
"My information is that this group has travelled in the Eastern states before coming to South Australia," Dr Spurrier told reporters.
Dr Spurrier said officials were investigating the movements of the group in the 24-hour time period before members fell ill, using the groups travel itinerary.
She said there was "absolutely no reason" for the community to panic.
"Anybody who is considered to be a close contact will be individually contacted," Dr Spurrier said.
The group would remain in isolation at their accomodation to reduce the spread of the disease.
Made up of mostly middle-aged travellers, Dr Spurrier said measures were being put in place to monitor the party to avoid deterioration of their health.
At the time of writing, none of the patients needed to be transferred to another hospital.
Updates will be published when they become available.
