COVID-19 Summer Surge: What You Need to Know and How to Stay Safe

COVID-19 Cases on the Rise in Canada Amid Summer Surge

Canada is experiencing a summer wave of COVID-19, with cases on the rise across the country. According to Dr. Isaac Bogoch, an infectious diseases specialist at Toronto General Hospital, while tracking methods aren’t as comprehensive as they once were, the available data indicates an increase in COVID-19 infections.

Monitoring the Spread: Wastewater Surveillance

Wastewater surveillance has become a key tool in tracking the spread of the virus. The Public Health Agency of Canada reports that current viral activity for COVID-19 is “moderate,” with higher levels in regions like Nova Scotia, Vancouver, and Toronto. While Ontario’s wastewater data is no longer updated, other provinces like British Columbia, Alberta, and Quebec continue to monitor the situation closely.

Understanding the Current Wave: The Omicron Sub-Lineage KP.3

The current wave is driven by the Omicron sub-lineage KP.3, which, according to Dr. Bogoch, is less severe than earlier Omicron waves that overwhelmed health-care systems. Despite this, COVID-19 remains a concern, particularly for those with risk factors for severe illness.

Precautionary Measures: What Still Works

Although public health mandates are no longer in place, familiar precautions—such as wearing masks indoors and staying home when sick—remain effective in reducing the spread of the virus. Dr. Bogoch emphasizes that these measures are still relevant for all respiratory illnesses, including influenza and RSV.

COVID-19 in Context: A Shift in How We Manage the Virus

COVID-19 is now being treated similarly to other respiratory infections like influenza and RSV. This marks a significant shift from how the virus was managed during the peak of the pandemic. However, the need for caution and respect for the virus remains, especially for vulnerable populations.
