What are the symptoms of yellow fever?

Yellow fever is a viral disease transmitted by mosquito bites, primarily affecting populations in Africa and South America. It can range from asymptomatic to severe, with a high fatality rate in serious cases.

Key insights from the research papers include:

Symptoms of yellow fever can vary widely, from asymptomatic or mild illness to severe disease with high mortality. Common symptoms include fever, chills, severe headache, back pain, general body aches, nausea, vomiting, fatigue, and weakness .
In more severe cases, symptoms may progress to jaundice, high fever, gastrointestinal bleeding, shock, and multi-organ failure. Seizures and hepatic encephalopathy are also noted, particularly in patients with severe forms requiring intensive care .
The onset of symptoms typically occurs three to six days after being bitten by an infected mosquito.
There is no specific treatment for yellow fever; management focuses on relieving symptoms and supportive care, including renal replacement therapy and plasma exchange in severe cases .

In conclusion, yellow fever presents a spectrum of symptoms, with severe cases leading to life-threatening complications such as organ failure and hemorrhage. Early symptoms are non-specific but can escalate rapidly, necessitating supportive care and symptom management, especially in severe cases.
