Measles is a very serious contagious disease that was once common during childhood. It is easily spread through the air (by sneezing or coughing) and by direct contact with someone who is infected. It can cause serious complications and even death. It is the leading cause of death in children worldwide from a vaccine-preventable disease. Before widespread immunization, measles caused an estimated 2.6 million deaths each year worldwide.
Measles immunization is very effective at protecting children and adults against infection and is the best way to reduce the risk of disease. Any unprotected individuals (persons who have not been immunized or do not have evidence of immunity) can become infected with measles.
Although local cases of measles in Canada do not occur frequently, measles is still common in other parts of the world and unprotected travellers can bring measles into Canada. This could result in local outbreaks, especially where immunization rates are low.

The destinations identified in which measles outbreaks are ongoing, to where the additional immunization recommendations for travel would apply, include:
The additional immunization recommendations for travel apply to all individuals travelling outside of North America. Additional information can be found at:
The measles situation is being constantly evaluated using multiple criteria, there may be other places experiencing cases of measles that do not fit the criteria for expanded recommendations. If additional sites are identified that do fit the criteria this information will be added to the Travel Advisories.
