Northwestern Health Unit says one new case of COVID-19 is in asymptomatic person

One of the three most recent cases of COVID-19 in the Northwestern Health Unit (NWHU), is from a person who shows no signs of the virus.

The remaining case, which has health officials scratching their heads a bit more than previous cases, is in Sioux Lookout.

"I think we're going to have to be thinking about this [one] a bit more, and perhaps asking a few more questions," said Dr. Ian Gemmill, the acting medical officer of health for the NWHU.

Gemmill said the person who tested positive showed no symptoms of the virus. They were screened, however, before undergoing some type of medical procedure or testat a hospital, and tested positive for COVID-19.

"And of course, one [could] also never findout what the source is, and that's when we start thinking about could this be local transmission."

"Because they were not symptomatic, we also believe that they were probably not likely to transmit it very effectively because we know that it's really close contact, and then exposure to the droplets that are caused by coughing, sneezing, laughing, singing, shouting, that sort of thing that can transmit it."

Gemmill said the hope is there was not sufficient transmission to spread the virus.

However, he said the NWHU would be taking the case seriously, and would be doing contact tracing.

He said the person had met with a few other households, and had dealt with some personal service providers, however, they would be at a very low risk of catching the virus from this affected person.
