Canada has had three times as many measles cases as the U.S. this year, according to the Canadian government and Centers for Disease Control and Prevention (CDC) data.
Canada has faced 4,206 measles cases this year, according to a government website, with 1,450 in Alberta, 2,301 in Ontario and 140 in British Columbia. However, the government also said 3,878 of the total cases were confirmed.
According to the CDC, there have been 1,333 confirmed cases in the U.S. in 2025, with Texas having the highest number of cases out of all 50 states at more than 700.
The federal government, especially Health and Human Services (HHS) Secretary Robert F. Kennedy Jr., has been facing scrutiny over its approach to vaccination, with Kennedy previously expressing vaccine skepticism.
In April, Kennedy touted the measles, mumps and rubella (MMR) vaccine as the “most effective” method to stop measles spreading amid a visit to Texas with the family of an 8-year-old girl who was killed by the disease.
“The most effective way to prevent the spread of measles is the MMR vaccine,” Kennedy wrote in a post on the social platform X at the time. “I’ve spoken to Governor Abbott, and I’ve offered HHS’ continued support.”
