A traveller from Sydney has added to South Australia’s COVID-19 tally since the state opened its borders to virus hotspots on Tuesday.
No details of the latest case have been provided but SA Health has listed exposure sites, including a Qantas flight that landed in Adelaide on Wednesday morning.
Anyone seated in rows one to four on QF733 is considered a close contact.
If they are unvaccinated they must quarantine for 14 days, or for seven days if fully vaccinated.
They must also get tested immediately and have two more tests on days six and 13.
The remaining people on the flight and people who visited the Krispy Kreme outlet at Adelaide Airport are regarded as casual contacts and should get tested and isolate until receiving a negative result.
Other locations of concern include the wider airport and a Foodland supermarket in Adelaide’s south.
Both are low-risk sites with anyone who attended at specific times asked to monitor for symptoms.
Thursday’s infection follows one detected on Tuesday in a young Victorian girl who travelled from Nhill to visit relatives in Adelaide and tested positive after arriving in SA.
After confirmation of the girl’s infection, chief public health officer Nicola Spurrier said the family had decided to return to their home in Nhill, in north-western Victoria, to quarantine.
The girl’s grandparents, who live in Adelaide, have been vaccinated and will quarantine at home for seven days.
Professor Spurrier said no other exposure sites had been identified and the risk to the wider community was low.
“The real message here is we are going to have cases in our state,” she said.
“This should be a wake-up call for anybody who is not vaccinated. There is going to be COVID in our community.”
An old coronavirus infection was also detected in another traveller from Victoria but was not considered an issue. It will not be added to SA’s tally of coronavirus cases.
Under SA’s new travel rules, anyone coming into the state must be double vaccinated and use a new online border entry process known as EntryCheck SA, which assesses an individual’s vaccination status, departure location and COVID-19 risk.
Based on the information provided, travellers may also be prompted to use a new HealthCheck SA app, which will help them monitor daily symptoms and guide them through any testing and quarantine requirements.
In most cases, travellers are required to have a COVID-19 test within 72 hours of departure.
Unvaccinated travellers will be required to seek a special exemption with applications to be assessed on a case-by-case basis.
