Today's Ottawa update

Ottawa Public Health (OPH) reported 46 new COVID-19 cases and no more deaths on Tuesday.

The city has a total of 475 known active cases, which is similar to what was seen in early June toward the end of the pandemic's third wave.

Medical Officer of Health Dr. Vera Etches said Monday she hopes a high immunization rate for vulnerable residents will keep the city from seeing the large rise in serious illness of previous pandemic waves, adding the situation is currently manageable for city hospitals.

Numbers to watch

11: As of Sept. 10, the risk of COVID-19 infection for unvaccinated people, or those who received their first dose less than two weeks ago, is 11 times higher than the risk for fully vaccinated people.

1.06: The number of people infected by a single COVID-19 case, or R(t). The rate of spread is considered under control when the number is below one.
