A second person has returned a positive test for COVID-19 at the Wimmera Health Care Group clinic in Horsham.
A spokesman for the group told the Mail-Times on Monday that the person was likely tested a few days ago as it takes time for the test to show results.
He said the clinic did not know where the person lived but that they had been sent home to self-isolate.
The first positive case from the clinic was recorded on Saturday and the patient was registered as residing in the Horsham municipality.
A specific location was not provided as the Department of Health and Human Services only issues updates on cases by Local Government Area.
The spokesman said this was the second positive case the assessment clinic has recorded since it opened on March 19.
"We're doing anywhere between 20 and 25 a day (of assessments) and about 10 of those a day have met the criteria for swabbing," he said.
The Wimmera recorded its first COVID-19 case on March 22, in the Yarriambiack Shire.
The Northern Grampians has recorded four positive cases of the virus,.
DHHS said on Monday the total number of COVID-19 cases in Victoria was 821 - an increase of 56 from yesterday.
