The use of wastewater surveillance has emerged as a powerful tool in the fight against COVID-19, providing critical data on community transmission levels. In Ontario, this technique has been successfully implemented to detect early signs of COVID-19 outbreaks in various regions. By analyzing samples of wastewater, scientists can detect traces of the virus that are shed by infected individuals. This helps to identify areas with high levels of viral RNA and predict where COVID-19 cases may be on the rise. The recent wastewater data from Ontario highlights the importance of ongoing monitoring to prevent further spread of the virus.Â

COVID-19 is a highly contagious disease caused by the SARS-CoV-2 virus. Since the outbreak of the pandemic, several different variants of the virus have emerged, each with distinct genetic mutations. Understanding the differences between these variants is important in order to effectively track and control the spread of the virus.
Wearing masks in high traffic public places has become an important measure to help slow the spread of COVID-19. Masks are designed to cover the nose and mouth, which helps to prevent the spread of respiratory droplets that can carry the virus. These droplets can be expelled when an infected person talks, coughs, or sneezes, and can linger in the air for a period of time. Wearing a mask can also protect the person wearing the mask from inhaling these droplets.
