WA Health has confirmed the Collie man who returned a very weak positive COVID-19 result yesterday is an historical case.
The man in his 30s poses no threat to community health and has not been included as a positive case in WA statistics.
The Collie resident had travelled back to Australia from Poland and quarantined in a Melbourne hotel for 14 days. He tested negative to COVID-19 in all his tests while in hotel quarantine.
On his return to Collie, he was retested as part of Vic Health’s follow-up of people post-quarantine.
He returned a very weak positive result, which is sometimes seen in people with old, recovered infections.
As a precaution, the man’s three closest contacts were asked to isolate pending further test results, including antibody tests.
All have been advised of the result and are no longer required to self-isolate.
