Their causes of death have not been confirmed and have been referred to the forensic pathologist.
The number of cases has increased by hundreds since the state registered 1374 infections yesterday.
“This (increase) seems to be associated with activities that took place on and around Christmas Day,” Mr Marshall said of the “significant leap”.
“Hopefully, those numbers will start to drop in the coming days.”
Currently, 44 people are in the hospital with “COVID-related issues.”
Only four patients are on intensive care.
It comes a day after it was announced that a COVID-19 positive child under the age of two had died.
Marshall said he has received correspondence from the child’s family.
“They’re asking for some privacy at the moment,” he said.
“This is a traumatic time for their family.”
The death of the child is a supplement to the death of a woman in the 90s this week, who has also contracted the virus. The causes of their death have not yet been confirmed and have been referred to the forensic pathologist.
The state introduces the booster shot mandate
Sir. Marshall also announced that a third COVID-19 vaccine will be made mandatory for workers in high-risk environments such as health care and geriatric care.
“Suffice it to say that three doses will be mandatory for those sectors where it is already mandatory (to be vaccinated),” he said.
It comes after a record day of testing yesterday, with 25943 tests performed.
“Southern Australia currently has the second highest test rate per capita in the country,” Mr Marshall said.
“And the second fastest turnaround times in any jurisdiction.”
South Australia Health confirmed that the facilities will reopen at 17.30.
“We will open them until midnight,” Mr Marshall added.
“We have further set up a facility in Hindmarsh. This will run from 10:30 today.”
He encourages anyone seeking a test to book an appointment first and not to seek one if it is asymptotic.
Interstate travelers will no longer be required to perform an entry check and rapid antigen test prior to entry into the state.
The changes will take effect immediately.
“It is not a good use of our resources at the moment,” Mr Marshall said.
“We ask all travelers coming from intergovernmental countries to observe exactly the same situation as all South Australians. That is, to monitor their symptoms and to act if they develop.”
In addition, fully vaccinated international arrivals should not be quarantined in the state from midnight tonight.
“It is still a requirement for those who are not fully vaccinated to stay 14 days in a media hotel,” Mr Marshall said.
Victoria registered 5,919 new COVID-19 cases and seven deaths.
