This is an update to the WHO advice posted on 31 January 2017.

As of 13 February 2017, yellow fever virus transmission continues to expand towards the Atlantic coast of Brazil in areas not deemed to be at risk for yellow fever transmission prior to the revised risk assessment published by WHO in the Disease Outbreak News of 27 January 2017, and supported by the scientific and technical advisory group on geographical yellow fever risk mapping (GRYF).

Currently there is no evidence of yellow fever virus transmission in the large metropolitan areas of the East Coast such as Rio de Janeiro, San Salvador, and Sao Paulo.

The determination of new areas considered to be at risk for yellow fever transmission is preliminary and updates will be provided regularly.

In view of the evolving situation, and considering that travellers for the Carnival in the next few weeks may take side tours outside the main cities, the current advice by the WHO Secretariat for international travellers going to areas of Brazil deemed to be at risk, including the above mentioned ones, is the following:

  • Vaccination against yellow fever at least 10 days prior to the travel.
    • Note that, as per Annex 7 of the International Health Regulations(2005), a single dose of a yellow fever vaccine approved by WHO is sufficient to confer sustained immunity and life-long protection against yellow fever disease.
    • Travellers with contraindications for yellow fever vaccine (children below 9 months, pregnant or breastfeeding women, people with severe hypersensitivity to egg antigens, and severe immunodeficiency) or over 60 years of age should consult their health professional for advice;
  • adoption of measures to avoid mosquito bites;
  • awareness of symptoms and signs of yellow fever;
  • seeking care in case of symptoms and signs of yellow fever, while travelling and upon return from areas at risk for yellow fever transmission.

For 2017 updates on yellow fever vaccination requirements and WHO vaccination recommendations for travellers see Annex 1 and country list on the WHO International Travel and Health website.
