Article: 55/4304

The World Health Organization (WHO) has reported that, from 23 to 24 September 2021, seven confirmed yellow fever cases in humans have been recorded in Monagas State, Venezuela, with six of these cases being unvaccinated against yellow fever.

Advice for travellers

Yellow fever is an acute viral haemorrhagic disease, transmitted by day-biting Aedes mosquitoes, and is found in tropical areas of Africa and Central and South America, including Venezuela. Travellers to these areas are advised to practice mosquito bite avoidance at all times.

A traveller's risk of yellow fever is determined by their individual risk assessment. Factors that will influence their risk includes: 

  • country or countries to be visited 
  • length of stay 
  • rate of transmission at destination 
  • immunisation status 
  • planned activities

Unvaccinated travellers that visit yellow fever endemic areas are at risk of becoming infected, so yellow fever vaccine is recommended, unless contraindicated.

Further advice and information on yellow fever is available on the TRAVAX (for health professionals) and fitfortravel (for the general public) websites.
