Young adults in Quebec were often the first infected during COVID-19 waves, a study reveals

Young adults were consistently among the first infected in Quebec's COVID-19 waves, a study found. This demographic may serve as an early indicator for emerging outbreaks. Researchers analyzed over a million cases from February 2020 to August 2022. They identified young adults, aged 18-29, as having a higher risk of being initial cases in clusters. This finding suggests public health could better target surveillance and interventions toward young adults to detect and respond to new waves of COVID-19 and other viruses more effectively.
