Travel Health Notice
Outbreaks caused by the four types of dengue virus have become increasingly frequent over the past 25 years. About 40% of the world's population lives in areas where there is a risk of dengue fever.
The Public Health Agency of Canada (PHAC) recommends that travellers protect themselves from mosquito bites when travelling to areas where dengue fever may occur.
Dengue fever is the most common viral disease spread to humans by mosquitoes. It can cause severe flu-like symptoms. In some cases, it leads to dengue haemorrhagic fever, which can be fatal. There is no vaccine or medication that protects against dengue fever.

It is widespread in parts of Central and South America; the Caribbean; South and Southeast Asia; Western, Eastern, and Central Africa; and Oceania.
