Why is it called yellow fever?


Yellow fever is called so due to one of its characteristic symptoms, namely the jaundice or yellowing of the skin and eyes that can occur in severe cases of the disease. The term "yellow fever" refers to the yellow discoloration caused by liver damage and increased bilirubin levels, which is a pigment produced by the breakdown of red blood cells. The yellowing of the skin, known as jaundice, is a result of bilirubin buildup and is a distinguishing feature of severe yellow fever cases. Other symptoms of yellow fever, such as high fever and headache, may also contribute to the name.


Yellow fever is a viral disease transmitted by infected mosquitoes, primarily in tropical regions of Africa and South America. It is characterized by symptoms such as fever, headache, muscle pain, nausea, and jaundice. In severe cases, it can lead to organ failure, bleeding, and even death. To avoid yellow fever, individuals should take preventive measures such as seeking out a travel health advisor, getting vaccinated with the yellow fever vaccine, using insect repellents, wearing protective clothing, and avoiding mosquito-infested areas, particularly during peak mosquito activity times. Travelers to endemic regions should also be aware of the risk and take necessary precautions. Additionally, efforts to control mosquito populations and improve public health infrastructure play a crucial role in preventing the spread of yellow fever.
