Possible third virus case in SA cleared

A third person in Adelaide who returned a weak positive test result for the coronavirus has been cleared.

SA Health says the person had no known link to the virus and was cleared on Tuesday after multiple follow-up tests.

Two other people, who arrived in Adelaide from China last month, are still being treated for the disease.

A number of other people have gone into self-isolation as a precaution after checks on the movement of the two confirmed cases.
