A concerning increase in measles cases in Canada is posing significant health risks for Canadians, warned an immunity expert at McMaster University in Hamilton. Dawn Bowdish, a professor and immunologist at the university, highlighted several factors and oversights that led to Canada losing its measles elimination status after nearly three decades last November. The Pan American Health Organization (PAHO) withdrew Canada’s measles-free status due to the surge in cases of the highly contagious viral infection.
According to Bowdish, the resurgence of measles in Canada carries severe health implications, including potential fatalities. The World Health Organization (WHO) reported that Canada has a disproportionately higher measles rate compared to the United States, despite having a smaller population.
The United States is also experiencing a rise in measles cases, surpassing previous records. Bowdish expressed dismay over Canada losing its measles elimination status, emphasizing the risks associated with measles infections, such as pneumonia, encephalitis, and even death. She pointed out various contributing factors to the increased measles cases in Canada, including the absence of a national vaccine registry, limited access to vaccinations, and loose exemption rules allowing unvaccinated children to spread the virus.
The skepticism towards vaccines has been fueled by the anti-vaccine movement, which is gaining momentum in some regions. Bowdish raised concerns about misinformation surrounding vaccines, particularly following an executive order signed by U.S. President Donald Trump. She emphasized the importance of enforcing mandatory vaccination rules to prevent further measles outbreaks.
PAHO stressed the need for countries in the Americas to address the surge in measles cases seriously, as the viral infection poses significant health risks. Daniel Salas, executive manager of PAHO’s Special Program for Comprehensive Immunization, emphasized the importance of not underestimating the threat of measles.
