South Australia has recorded 14 new infections in hotel quarantine.
The stateâ€™s health department released the concerning figure on Monday afternoon, saying all cases were returned travellers in medi-hotels.
The positive infections include a male and female in their 20s, four females in their 30s, a male in his 40s and four children â€” two boys and two girls.
It brings the stateâ€™s total number of cases to 719 with 32 currently active.
The high figure comes after SAâ€™s chief public health officer Nicola Spurrier said health authorities were â€œconcernedâ€ with the increasing number of active coronavirus cases.
She said they were in talks with the federal government about the number of overseas arrivals the state could handle.
It came after the state recorded nine new hotel quarantine cases on Thursday.
â€œThis puts me on edge and also members of my staff to make sure weâ€™re still protecting SA,â€ she said.
â€œSo we need to make sure all of our processes in our quarantine stream and medi-hotel are as tight as possible.
â€œWe feel that weâ€™re getting near capacity in terms of our concerns around safety.â€
SA Health also advised on Monday that anyone who travelled into the state from the Perth or the Peel region since April 17 should go get tested and remain in isolation until they received a negative result.
Those people must also be retested on days five and 13.
â€œAnyone who has been in the Perth or Peel regions are currently not permitted to enter South Australia from 12:01am Saturday, April 24,â€ it said in a statement.
â€œEssential travellers are permitted, but must isolate for 14 days.â€
There have been 144,539 vaccines administered.
