The global measles outbreak continues to surge in 2026, with significant increases in popular travel destinations like the southern U.S. and Mexico. Health authorities are advising Canadians to verify their vaccination status before traveling abroad this winter.
Mexico has recorded over 2,700 new measles cases this year, predominantly affecting infants and young children. The U.S. has also reported more than 900 confirmed cases, with Florida and South Carolina experiencing substantial outbreaks.
In Canada, there have been dozens of new measles infections reported, including a cluster of over 70 cases in Manitoba. The country recently lost its measles elimination status following a major outbreak in 2025, leading to severe consequences for affected families.
Dr. Natasha Crowcroft, Canada’s acting Chief Public Health Officer, emphasized the importance of preventing additional outbreaks, especially with the upcoming March Break travel season. The Pan American Health Organization reported a 40-fold increase in measles cases across the Americas in the early weeks of the year.
The resurgence of measles is attributed to various factors, including a rise in anti-vaccine sentiment and a decline in routine childhood immunizations during the COVID-19 pandemic. Dr. Demetre Daskalakis highlighted the impact of a weakened public health system in the U.S., contributing to vaccine hesitancy and global distrust in vaccination.
Maintaining high vaccination coverage is crucial to combat measles, as the disease poses significant risks, particularly to vulnerable populations. Dr. Alon Vaisman emphasized the need for immunization to prevent the spread of this highly infectious disease.
As many Canadian families plan trips to measles hotspots like Mexico, immunologist Dawn Bowdish stressed the importance of staying up to date with vaccinations, especially for pregnant individuals and young children. She recommended early measles shots for infants traveling to outbreak areas for added protection.
It is essential for all family members to check their vaccination status before traveling, following the guidelines outlined in the Canadian Immunization Guide. Ensuring proper immunization is crucial in preventing further measles outbreaks and protecting public health.
