What are the Symptoms of Yellow Fever?
Symptoms of yellow fever usually develop after 3 - 6 days following a mosquito bite.
There are two stages of the illness-
► Acute phase
► Toxic phase
The first, ‘acute’, phase usually causes-
► Muscle pain
► Loss of appetite
Most of the patients improve and their symptoms disappear after 3-4 days.
However, 15% patients enter a second, toxic phase within 24 hours of the initial remission. Several organs are affected in this stage, including the heart, liver and kidney.
► High fever
► Abdominal pain with vomiting
► Bleeding from the mouth, nose, eyes or stomach
► Blood in the vomit and feces
► Deterioration of kidney function
50% patients who enter the toxic phase die within 10-14 days, the rest recover without significant organ damage.
