Yellow Fever is a virus of the flaviviridae family and is transmitted by the bite of the female of the Aedes spp. or Haemogogus spp.s mosquitoes. It is a risk in tropical parts of Africa and South America,Eastern Panama and Trinidad in the Caribbean.
Countries at risk of Yellow Fever transmission are countries were infection occurs in humans and or primates and the above types of mosquitoes occur. The symptoms of Yellow Fever ranges in severity from a self limiting febrile illness to severe liver disease with bleeding and death. There is no specific treatment for Yellow Fever other than symptomatic support. If you are going into an area where Yellow Fever is a risk or the vectors are present you would require vaccination against the disease. Yellow Fever vaccine requirements are legally enforceable for entry into some countries and has to be done at least ten days before entry into the country. This is done to protect travellers but also to prevent the spread of the disease into countries not affected. If you are unsure if you need the vaccination it is best to get specialist advice from your doctor. Only Yellow Fever Designated Centres, such as mine, are allowed to give the vaccine and you have to be specially trained to perform the vaccination. You can check on the Nathnac website to see where your local Yellow Fever Designated Centre is.
We also recommend that you protect yourself from getting bitten by using an effective insect repellent, wearing long sleeved clothing and treating clothes with a repellent . Staying in air conditioned rooms and using mosquito nets.
