  • Yellow Fever in Africa is recognised in two different forms - urban and jungle. 'Urban Yellow Fever' occurs when an infected person enters a densely populated area and is spread from person to person by any type of mosquito. 'Jungle Yellow Fever' is essentially a disease of monkeys living in tropical rainforests is spread to humans by rainforest mosquitoes.
  • The Yellow Fever vaccine prevents the disease.

Yellow Fever Symptoms

  • Yellow Fever symptoms may be mild at first and go unrecognized - headaches, fevers, abdominal pain.

Yellow Fever Vaccination Exemption

  • If your physician confirms there is a medical contraindication to yellow fever vaccination, a medical waiver can be issued.inistering the vaccine. In this case, the provider should fill out and sign the Medical Contraindications to Vaccination section of the ICVP (International Certificate of Vaccination or Prophylaxis). Also, it is the provider's responsibility to counsel the traveller about the risks of travelling without vaccination to a country with risk of yellow fever virus transmission and about personal protective methods against mosquito bites. Travellers in this situation should be advised that the safest alternative is to avoid or postpone travel.
  • Additionally the physician who grants a medical waiver should provide a signed and dated exemption letter on letterhead stationery, clearly stating that the vaccine is contraindicated on medical grounds. This letter should also display the centre's official yellow fever vaccination stamp. Medical exemption letters should be written for the current trip only.

  • Confusion still exists as to which countries require a compulsory Yellow Fever certificate. A Yellow Fever Certificate is the ONLY internationally regulated certificate. The WHO recommends it for all travellers to endemic areas, as well as for those coming from an endemic area to an area of potential transmission. The purpose of the certificate is not only to protect the traveller but to also protect those in areas of the world where infection is possible.
