Symptoms Linked To Yellow Fever

Jaundice

If the virus reaches its toxic stage, the symptoms of yellow fever become far more severe. The first sign the disease may be heading towards the toxic stage is jaundice, or yellowing of the eyes and skin, and can also cause the darkening of urine and lightening of stool. This yellow pigmentation of the skin is usually caused by a build-up of bilirubin, which usually signifies a build-up of bile in the liver as well as an early warning sign there may be other potential and more serious liver problems such as liver damage, blockage of the bile duct in the liver, or improper secretion of bile in the body. Bilirubin is produced by the breaking down of red blood cells by the bile in the liver, which in turn results in the yellow skin tone and yellowing of the whites of the eyes.
