COVID-19 in Sudbury & districts: Your weekly update December 30, 2021

Reporting period: Thursday, December 23, 2021, to Wednesday, December 29, 2021.

December 30, 2021 — The following is a summary of how the status of COVID-19 has changed in Public Health Sudbury & Districts’ service area over the last seven days up to end of day December 29, 2021: 591 new cases were reported and 240 cases were resolved. Seventy-eight (78) cases in the past week have mutations that are consistent with the Omicron variant. With the rapidly evolving situation and given the epidemiology and laboratory findings across the province, we can now presume that cases who screen positive for Omicron are indeed the Omicron variant. Eleven (11) COVID-19 outbreaks were active this week, including 5 in schools or on school buses, 4 in long-term care homes, and 1 each in a workplace and a community setting (public park). Four (4) outbreaks were declared over in the past 7 days, 2 in schools, 1 in a workplace and 1 in a long-term care home. There were no COVID-related deaths. At end of day December 29, 2021, there were 650 active cases in our service area and 8 active outbreaks. There were 6 local cases in hospital, while the rest were self-isolating.

Since the beginning of the COVID-19 pandemic, there have been a total of 5 287 local cases of which 4 637 are resolved. Sadly, 47 people have died in our service area.

Of the 799 local cases of COVID-19 reported since December 1, 2021, 325 cases have been among fully vaccinated individuals. There have been 474 cases in unvaccinated or partially vaccinated residents (those having received one-dose only). During that same period, there have been 14 local hospitalizations of which 10 cases were unvaccinated or partially vaccinated. Four (4) hospitalized cases were fully vaccinated. Interpreting vaccine status data: please note that data on case counts by vaccination status are preliminary—and highly subject to change. Comparing cumulative numbers from week to week may lead to incorrect estimates of case counts by vaccination status for the previous 7 days.

Based on local data from the last 14 days, the risk of contracting COVID-19 for unvaccinated residents of Sudbury and districts was 1.7 times the risk for fully vaccinated residents. Additionally, provincial data from the same period indicate that the risk of an unvaccinated individual currently being in hospital due to COVID-19 was 3.4 times that of a fully vaccinated person. Further, their risk of currently being admitted to the intensive care unit (ICU) was 8.5 times that of a fully vaccinated person.

Stay COVID-safe

  • As we celebrate the end of another year, this time in the midst of an unprecedented surge in COVID-19 cases fueled by the Omicron variant, it is critical to protect yourself and those around you from the virus. Remember that although the gathering limits are 10 people indoors and 25 people outdoors, the fewer people the safer for everyone. Continue to follow all public health measures while hosting or attending a celebration. Celebrating virtually or outdoors is safest. When outdoor gatherings are not possible, ensure proper ventilation indoors. Consider the vaccination status of everyone attending. Remember that a negative rapid antigen test is no guarantee and continue to follow all safety measures. Stay home if ill, even if symptoms are mild.
  • In the face of the Omicron variant and the unprecedented increase in COVID-19 cases, vaccination and following public health measures remain critical to help control the spread of COVID-19, protect health, and prevent overwhelming our health care system. Eligible individuals should get their booster dose as soon as possible. It remains important for everyone else to get their first or second dose if they have not already.
  • Navigating through the many changes and uncertainties of the COVID-19 pandemic has been challenging; however, we recognize that holidays can also be difficult for many. With this extra added strain on our mental health, remember you are not alone. Reach out for support.

Message from Dr. Penny Sutcliffe, Medical Officer of Health

Locally and across the province, COVID-19 cases are rising at an alarmingly rate—seeing heights not previously experienced. Moreover, the cases we do know of are likely just the tip of the iceberg—more and more, the confirmed cases reported by public health agencies are an underestimate of the true number of people with COVID-19. With Omicron now the dominant COVID-19 strain in Ontario, it’s critical that our community acts in unison to reduce current and future strain on our health system, which could be quickly overwhelmed. The rise in COVID cases not only threatens access to much needed medical care, but also directly affects social and mental health, our local economies, and families and neighbourhoods. With New Year’s Eve upon us, please keep your celebrations virtual and if in person, keep them minimal. Choose COVID-safe options to reconnect with friends and loved ones, such as very small outdoor gatherings with physical distancing or virtual gatherings. Following public health measures, without exception, is critical right now. On behalf of Public Health Sudbury & Districts, I want to extend my very best wishes to all for a safe and healthy 2022 – a New Year that ultimately sees the end to the global pandemic – an end that is possible thanks to the hard work and sacrifices of so many. Thank you and Happy New Year!
