What is it?
Yellow Fever is a potentially fatal, vaccine-preventable disease caused by A flavivirus
It is transmitted by the bite of an infected mosquito
Yellow Fever gets its name from the yellowing of the skin and eyes (jaundice) that occurs when the virus attacks the liver
What are the symptoms?
Most people who get Yellow Fever will experience 3-4 days of fever, chills, aches and pains, nausea, vomiting and loss of appetite, after which they will fully recover
About 15% of people will enter a second, more serious phase of the illness that is characterized by fever, abdominal pain, vomiting, dehydration, listlessness, jaundice, kidney failure and bleeding from the mouth, nose or eyes. Up to 50% of these people die
Survivors will have no long-term organ damage or other ill effects
How can I contract Yellow Fever?
You can get Yellow Fever if you are bitten by an infected Aedes or Haemogogus mosquito in urban, rural and jungle environments in Africa and South America
Your risk of becoming infected increases depending on when you travel, the length of your stay and the kinds of outdoor activities you take part in (for eg., camping, hiking or cycling)
When there are no epidemics, Yellow Fever is rare in urban environments
What vaccines are available?
The YF-VAX vaccine is available in Canada from designated Yellow Fever Vaccination Centres
All TMVC locations are designated to provide this vaccine and issue an International Certificate of Vaccination for countries that require it
To ensure full protection, you should get this vaccine at least 10 days before you enter a Yellow Fever endemic area
However you can still be vaccinated if you are leaving sooner
How many shots will I need?
The Yellow Fever vaccine is given in a single, one-time shot
Will I need a booster?
Since 2016 the vaccine has been considered valid for life
How can I prevent Yellow Fever?
Minimize mosquito bites by using insecticide sprays and insect repellents containing at least 30% DEET
Limit your outdoor activities
Wear permethrin-treated clothing
