Kidney failure
Kidney failure is one of the severe symptoms of yellow fever. Kidney failure (renal failure) means one or both of your kidneys no longer function well on their own. Kidney failure can occur suddenly and is occasionally transitory (acute). Sometimes it's a chronic (long-term) illness that deteriorates gradually.
The most serious stage of renal disease is kidney failure. Without treatment, it is lethal. You may make it through a few days or weeks without assistance if you have kidney failure. A kidney's functions are varied. Helping your body clear toxins is one of its most crucial tasks. Your kidneys filter your blood, removing waste from it through urine (pee). Whenever your kidneys aren't functioning properly, waste products accumulate in your body. You will become ill and finally pass away if this occurs. With the right care, many people can manage renal failure.
