Toronto Public Health officials are asking residents to take further action in the fight against COVID-19 amid a "significant increase" in the number of local cases amidst a global outbreak.

Dr. Eileen de Villa, Medical Officer of Health for the City of Toronto, announced during a press conference this afternoon that we are now starting to see cases emerge "which are unlinked and thus indicate community transmission."

While unable to comment on the specifics of these cases, de Villa told reporters at City Hall that she was aware of at least three patients who are believed to have contracted the virus independent of recent travel or close contact with someone who had recently travelled outside of Canada.

"Last week I made a number of recommendations on public health measures to protect our city," she said during the first of what will now be daily media briefings on the COVID-19 pandemic in Toronto.

"At this time I am urging you to take further action... please note that I do not make these recommendations lightly."

In light of the fast uptick in cases of the deadly coronavirus, de Villa has formally asked all residents in the city to stay at home if possible.

"If you can stay home, do," she said. "If you are a business or an employee, help your staff to stay home. Limit group gatherings. if you need to seek medical attention call ahead... I cannot overemphasize how important this is, particularly at this critical time."

De Villa extolled the importance of social distancing in helping to minimize the outbreak and save the lives of vulnerable citizens.

"Increasing social distancing is a key component from preventing the kind of circumstances we're seeing in other jurisdictions," she noted, referring to places like China and Italy where the virus spread fast with disastrous public health consequences.

"Every interaction avoided helps to flatten the curve," she said. "If you can, stay home. Help out our city by reducing your interaction with others. Every little bit, every effort counts."

Help prevent the spread of #COVID19 by practicing #SocialDistancing. While you may not feel sick, we ask that you be mindful of those more vulnerable in our community & thank you for your efforts to keep everyone healthy. More info: https://t.co/DyBararcmS pic.twitter.com/k7WMsOA2pJ
