Yellow Fever

Yellow fever (YF) is a serious viral disease transmitted by infected mosquitoes, particularly species active during the day. The virus is endemic in tropical regions of Africa, South America, parts of Central America, and Trinidad in the Caribbean. Yellow fever can present with a range of symptoms, from mild illness to severe, life-threatening conditions involving jaundice (yellowing of the skin and eyes), bleeding, and major organ failure. While yellow fever is rare among Western travellers, unvaccinated individuals visiting risk areas are vulnerable, particularly during the late rainy to early dry seasons when transmission is most intense. Factors such as travel destination, duration, and activities that increase mosquito exposure, as well as vaccination status, play a significant role in determining risk.

Symptoms

Yellow fever symptoms typically begin three to six days after a mosquito bite. Mild cases may involve fever, headache, muscle pain, nausea, and fatigue, which often resolve within a few days. However, in some individuals, the disease progresses to a toxic phase characterised by high fever, jaundice, abdominal pain, bleeding, and organ failure, particularly of the liver and kidneys. The fatality rate in severe cases is high, emphasising the importance of prevention. Prompt medical care can help manage symptoms, but there is no specific treatment for yellow fever, making vaccination and mosquito bite avoidance critical preventive measures.

Vaccination

The yellow fever vaccine is a highly effective, live-attenuated vaccine that provides long-term protection against the disease. It is recommended for travellers visiting areas where yellow fever is endemic. While serious side effects are rare, individuals with specific medical conditions or weakened immune systems should consult a healthcare professional before vaccination. For most people, a single dose of the vaccine provides lifelong immunity, though travellers should check with their provider about updates to their immunisation status if concerned.
