Yellow Fever

What is Yellow Fever?

Yellow fever is a viral infection passed by the bite of an infected Aedes or Haemagogus mosquito, in some tropical areas of the world.  Infection may cause fever, chills, headache, muscle pain and may result in bleeding, organ failure and death.  

Protection includes insect precautions and vaccination.  Some destinations require proof of the vaccine for entry into that country. You must be vaccinated 10 days or more prior to arrival for the vaccine to be considered effective. The protection lasts for at least 10 years.  

A special certificate is issued and should be kept with your passport and other important documents. This certificate can only be issued by a designated Yellow Fever Vaccination Centre.




Insect precautions:


  • Cover skin with long sleeve shirts and pants. Consider treating outer clothing with permethrin product.

  • Wear light or medium-coloured clothing and avoid scented soaps and deodorants.

  • Apply insect repellent that contains either 30% DEET or 20% Icaridin, to exposed skin and clothing, especially during the day.

  • Sleep under a treated bed net or in an enclosed air conditioned room.

  • Nets should be used over cots, playpens and strollers to protect infants.
