Yellow fever is an acute viral disease transmitted by mosquitoes, occurring mainly in tropical regions of Africa and South America. The disease can lead to severe complications including jaundice, hemorrhages, and organ failure.
Overview
Yellow fever is a viral disease transmitted by mosquitoes of the Aedes and Haemagogus genera. It occurs endemically in tropical regions of Africa and South America. The disease can progress mildly or severely, with symptoms of fever, jaundice, and hemorrhages.
Emergency Signs

The disease can progress mildly (viremic phase) or severely (toxic phase) with jaundice and hemorrhages.
Diagnosis
How this disease is identified
Diagnosis is based on clinical symptoms, laboratory tests, and serological tests.
Treatment
Available treatment methods
Treatment is symptomatic - rest, hydration, antipyretics. In severe cases, hospitalization is necessary.

How common is it?
Statistics and geographic data
The disease occurs endemically in tropical regions of Africa and South America. It is estimated that 200,000 cases occur annually.
Risk Factors
Who is most at risk
Traveling to endemic areas without vaccination, being outdoors during mosquito activity hours.
Complications Details
Potential complications
Severe complications include liver, kidney, and heart failure, hemorrhages, shock, and death.
