An individual who attended the Outdoor Kemptville Christmas Market recently tested positive for COVID-19.
Meanwhile, eight new cases were reported since the tri-county heath unit's last report of last week.
The Leeds, Grenville and Lanark District Health Unit declined to identify whether the positive case, which happened on the weekend of Nov. 21 and 22, was a vendor, a visitor or a resident.
"We don't share details about individual cases unless there is a risk to the public identified,” said health unit spokeswoman Susan Healey.
"We can tell you that we did send letters on Wednesday to close contacts of a positive case from the Kemptville Market."
Healey went on to say that the health unit did a full assessment of the outdoor market facility and identified that all necessary precautions were in place at the event.
The vendors were notified through the market manager and information was posted on the market website in case people were concerned, said Healey.
Anyone who attended the market but has not received a letter from the health unit has not been identified as a high risk for contact with the positive individual.
The health unit continues to encourage local residents and visitors to follow public health guidelines for mask-wearing, social distancing and hand-washing, and to get tested if they experience any symptoms.
Meanwhile, a rash of positive results over the weekend means there are now 13 active cases of COVID-19 in the tri-county region.
The latest count from the local health unit on Monday shows there were eight new cases since its last report on Friday.
Since the pandemic began, 492 cases of the virus have been reported locally. A total of 426 people have since recovered while 53 have died.
Of the 13 active cases, 12 are in the community at large while one is a health care worker. Two people recovered since the last report, while one person remains in hospital and on a ventilator.
There are currently no outbreaks at any long-term care centres or retirement homes, and the positive case at South Branch Elementary School in Kemptville remains the only one affecting a local school.
The positive case in a staff member was reported two weeks ago, but the case count remains at one and the virus did not spread. An outbreak was not declared and the school remained open.
The active virus cases are now concentrated in Leeds, despite previously being focused in Lanark east and Grenville near Ottawa for weeks. The latest report shows there are six cases in West Leeds and three cases in the Leeds area that includes Brockville.
Grenville has just one active case, while east Lanark has three.
