There were no positive cases of COVID-19 in the NWT as of early Thursday afternoon.
A total of 222 tests have been performed, and all results were negative, according to an update from the Department of Health and Social Services (HSS).
It takes seven days for results to be known and tests must be sent to a laboratory in Alberta for processing, the GNWT said.
The update comes as the NWT's chief public health officer Kami Kandola on Wednesday announced a public health emergency in the territory, though she didn't order the closure of any businesses or facilities.
Across Canada there were at least 736 positive cases of coronavirus and 10 deaths, according to an update by the Public Health Agency of Canada on Thursday morning.
