On February 23rd, 2023, the rise of COVID-19 cases in Ontario was reflected in the wastewater samples collected across the province. Wastewater surveillance has become a vital tool for detecting and monitoring COVID-19 outbreaks in communities, providing valuable insights into the spread of the virus.

The latest wastewater data shows an upward trend in viral RNA levels, indicating an increase in COVID-19 prevalence in the population. This rise in viral RNA levels is a concern as it indicates that there could be an increase in the number of people infected with COVID-19 in the coming days and weeks.

The wastewater surveillance program in Ontario is an early warning system that allows public health officials to quickly identify and respond to COVID-19. This information can help guide decisions around public health measures.

It's important to remember that while the vaccine rollout is underway, we still need to remain vigilant and follow public health guidelines to prevent the spread of COVID-19. This includes wearing masks, practicing physical distancing, and washing our hands regularly.
