An eight-month-old baby is one of two new cases of coronavirus confirmed in South Australia.

This takes the total number of cases to seven, while 14 South Australians are waiting for results of tests.

The baby is the son of a 40-year-old woman, who had tested positive for the disease. The other new case is a man, 58, who arrived from Taiwan and is now in the RAH.

SA Health said the mother and baby were “doing well” in Flinders Medical Centre. She had travelled from Iran via Kuala Lumpur before falling ill on arrival in Adelaide.

The new cases come as SA Health reveals its specialised coronavirus clinic at the RAH.

The new clinic assesses and tests possible carriers of the virus, ensuring they bypass the emergency department, reducing the risk of spreading the illness. Other hospitals are preparing similar clinics.

It cames as a “critical” shortage of surgical masks has left dentists on the brink of shutting up shop, with the top industry association warning that current supplies could last only four more weeks amid the continuing crisis.

Thousands of dentists nationwide are facing dwindling supplies that could force clinical closures because of a lack of essential protective equipment.

The Australian Dental Association revealed that Australian dentists used up to 9.5 million masks a month treating patients, with the shortage having “a broad-reaching impact”.

“Some practices order between 15-20 boxes a fortnight and they’re being limited to two or three … it’s pretty serious,” acting chief executive Eithne Irving said.

It came as Australian Medical Association director Dr Tony Bartone said many members had expressed concerns about how to handle the virus challenge, with a potential escalation likely.

Salisbury North woman Kirstyne Rawlings said such confusion was clear when she took husband Chris to Lyell McEwin Hospital after being sent by a GP amid fears he had symptoms after working with people who had been in Asia. After ringing ahead, she said she was told to go to the ED but not inside then was told they should wait in their car.

“We were told they needed to set up an isolation area, which took about half an hour, then we were left in an isolation room for about four hours,” she said.

“They took a swab from Chris but not from me then told us to go home and self-isolate for 72 hours – they clearly were not prepared.”

In other developments:

Mount Barker Central Shopping Centre sent a memo to tenants saying they had been advised by SA Health a person working at a travel agency had been confirmed with coronavirus.

“SA Health have advised us the person in question was only working in the tenancy for a minimum amount of time, and unless you were in direct contact with her, the risk of transmission is very, very low,” it says. The woman, 24, remains in a stable condition in an Adelaide hospital.

Prime Minister Scott Morrison has put a new travel ban in place for those coming from South Korea, and increased screening measures for travellers from Italy.

The Anangu Pitjantjatjara Yankunytjatjara Lands will close its borders to anyone confirmed to have coronavirus, or who has travelled to Iran, South Korea, Japan, Italy or Mongolia.
