About yellow fever

Yellow fever is a severe and potentially deadly disease that has become increasingly common in the UK in recent years. The virus is spread through infected mosquitoes and can cause severe symptoms, including fever, headache, jaundice, muscle pain, nausea, vomiting and fatigue. In rare cases, it can even lead to death.

You can take preventive measures if you travel abroad to areas where yellow fever is present, like Africa or South America. Vaccination is recommended for travellers over one-year-old heading to these regions and anyone who lives near an endemic area or works with infected animals like monkeys. Additionally, it's essential to take precautions against mosquito bites by wearing long sleeve clothing outdoors and using insect repellent containing DEET or Picaridin for extra protection. 


How can you get yellow fever?

Transmission of YF occurs in three cycles:

  • Jungle: occurring in tropical rainforests of Africa and South America. The transmission cycle occurs between monkeys and jungle-breeding mosquitoes. Humans can become infected when they live or work in areas where this cycle occurs.

  • Savannah (Africa only): occurs in the moist savannah regions where humans live and work close to the monkey population. The transmission cycle occurs between monkeys and humans, spread via infected mosquitoes.

  • Urban: following infection during the jungle cycle, infected humans can introduce the virus to urban areas with a high population density. Virus transmission occurs between humans in areas where the domesticated mosquito vector (i.e. those that breed around human habitation) is present.

Once infected with the virus, the mosquito remains infectious for life (two to three months). Generally, mosquito species are most active during high rainfall, both in the jungle and urban environments. YF virus can survive very dry conditions in mosquito eggs, which hatch once a water collection is replenished. This can result in YF outbreaks in urban and rural areas, even during the drier months.
