The concerns surrounding the spread of coronavirus in Ontario show no signs of slowing down for the time being. The number of people being investigated for potential COVID-19 cases more than doubled overnight between Tuesday, March 3 and Wednesday, March 4, according to official data. 102 Ontarians are now being monitored, though the number of confirmed cases has not risen. 

According to the page of the government of Ontario website that tracks new information on the virus, the province currently has 20 confirmed cases with 17 people being treated. Three have successfully recovered.

However, 102 cases are now under investigation, per government data from 10:30 a.m. ET on Wednesday.

CBC states that as of the previous update on March 3, there were only 45 such cases waiting for results.

Since the outbreak reached the province, 1,216 potential cases have been found as negative. That represents its own rise from the previous update, which recorded 1,061 negatives.

Back in February, Ontario's concerns were increased when it was faced with its first human-to-human spread of the virus.

According to Global News, two women had made recent trips to Iran and the husband of one of them was confirmed to have the virus despite not having travelled with her.

The alarm has risen so much in some areas that Ottawa Public Health has made a list of what to stock up on due to COVID-19.

And it looks like people have already taken the list to heart as some Costco shelves are being left bare as people purchase necessities amid the scare.

According to CBC, travellers from Iran to Canada are now being asked to ensure they self-isolate for two weeks in order to prevent the spread of the virus.

Narcity reached out to the Ministry of Health but was told the Ministry had no comment.

However, Ontario's Chief Medical Officer of Health Dr. David Williams says that all health protocols have been followed in the province and the risk of infection still remains pretty low, via Global.

Narcity has reached out to Public Health Ontario for comment.
