Canadian health officials have issued new travel advisories in response to an outbreak of the Oropouche virus disease in several countries across the Americas, including some popular destinations for spring getaways. The advisory, posted on Canada’s Travel Advice and Advisories page, urges travellers to stay informed and take precautions when visiting affected regions.
The Oropouche virus is primarily spread through the bites of infected midges—tiny insects also known as “no-see-ums”—and possibly some types of mosquitoes. The virus has been present in the region before, but there has been a recent surge in cases, including in countries that had not previously reported outbreaks. Canada has noted travel-related cases, particularly among people returning from Cuba.
As of June 5, the advisory applies to Cuba, Bolivia, Brazil, Colombia, the Dominican Republic, Panama, and Peru. Midges are most active during the afternoon, while mosquitoes are typically a nighttime threat.
There is currently no vaccine to prevent Oropouche virus infection. Symptoms usually appear three to eight days after a bite and include chills, fever, severe headaches, and joint and muscle pain. Some individuals may also experience rash, nausea, vomiting, light sensitivity, dizziness, and pain behind the eyes. While symptoms typically last about a week, the illness can recur days or even weeks later.
Most people recover without lasting effects, but in rare cases, the virus can lead to severe complications such as meningitis, encephalitis, or internal bleeding. Anyone showing symptoms is advised to seek medical attention. Treatment focuses on relieving symptoms and supporting recovery, as there is no specific antiviral medication for the disease.
To protect against infection, travellers are encouraged to use insect repellent approved by health authorities, wear tightly woven long-sleeved clothing and pants, and stay in accommodations that prevent insect entry. In areas without full protection, using insecticide-treated mosquito netting is also recommended.
With many Canadians planning spring and summer travel, officials stress the importance of staying vigilant and following preventive measures to reduce the risk of exposure.
