Four South Australian Upper House MPs have entered self-imposed quarantine as a precaution because of coronavirus concerns.

Key points: Two SA Best and two Greens MPs are working from home

SA Best MPs Frank Pangallo and Connie Bonaros met with a staffer from Senator Rex Patrick's office last week.

Senator Patrick has since tested positive for the virus, and Mr Pangallo said Mr Patrick's staff member was now awaiting a test.

Greens MP Tammy Franks told the ABC she was experiencing flu-like symptoms after being in close contact with her SA Best colleagues in Parliament House.

Her colleague, Greens MP Mark Parnell, said he was "feeling fine" but decided to self-quarantine out of caution.

Mr Parnell's parliamentary office is located close by to those belonging to SA Best MPs.

"To my knowledge, there's no Member of Parliament who has tested positive," he said.

"When you hear that someone may have visited, that may have been in contact with someone, then out of an abundance of caution we work from home.

"No-one was legally or otherwise required to self-isolate [but] I think it makes sense … not to risk anyone."

Health Minister Stephen Wade earlier confirmed several members of Parliament had self-isolated.

"The South Australian Parliament is part of the community and it's not surprising that it's impacted on the Parliament," he said.

Mr Parnell said he had watched today's proceedings via a live stream, and he and his colleagues were keeping in touch with Parliament through electronic means.

"The work of Parliament continued today. Members expressed how they wished to vote through text messages and other methods," he said.

He said it was "highly unusual" to vote on bills in such a manner and said the majority of communication had been done by email.

"Parliament is scheduled to resume in a fortnight's time and I'm hoping that we'll have a full complement of MPs back then," he said.

"There is still very important legislation to pass to make sure that our society is able to cope with this virus.

"MPs do need to lead by example but the tension, of course, is that the community expects us to be on the job and doing the work of making sure essential community services are kept going."

About 200 people who attended a recent function with Senator Patrick, in Cummins on Eyre Peninsula, have been directed to self-isolate for a fortnight.

That includes an ABC staff member, and the ABC's Port Lincoln office has temporarily closed as a precaution.
