Montreal public health director Mylene Drouin introduced the website Aplatir.ca (Or https://flatten.ca/?lang=fr#home) in a Friday afternoon news conference.
The web app was developed by University of Toronto professors and students and has been used by some 300,000 people throughout the country so far.
The app does not ask for personal data beyond the first three digits of your postal code to allow public health officials to track symptoms throughout the city.
The Quebec government also has an online triage site to help residents evaluate their risk of getting COVID-19.
As of Friday, there are 2,837 people infected with COVID-19 in Montreal. Of them, 169 have been hospitalized, including 31 in intensive care. Montreal has counted 29 deaths so far. As many as 175 local health professionals have also been infected with the virus. Participation is voluntary, but Drouin asked that anyone with COVID-19-like symptoms use it.
