The Canadian Institutes of Health Research (CIHR) and the Government of Canada are investing $4 million in a new research network focused on the prevention, control, diagnosis, and treatment of Lyme disease. Operated by Queen’s University, the Pan-Canadian Research Network on Lyme Disease aims to influence health outcomes, practice, programs and policy related to Lyme disease, whose prevalence in Canada is increasing due to climate change. Lyme disease is spread by black-legged ticks, which travel north with warmer temperatures. The disease's symptoms are notoriously variable, making it difficult to identify and treat. CIHR’s investment in the network is coordinated with the Public Health Agency of Canada and forms part of the federal government’s support of the Pan-Canadian Framework on Clean Growth and Climate Change. Queen’s University Professor of Emergency and Family Medicine Kieran Moore will lead the network.
