Yellow fever is spread by a species of mosquito common to areas of Africa and South America. Vaccination is recommended before traveling to certain areas.
The Flavivirus causes yellow fever, and it’s transmitted when an infected mosquito bites you. Mosquitoes become infected with the virus when they bite an infected human or monkey. The disease cannot be spread from one person to another.
Mild cases cause fever, headache, nausea, and vomiting. Serious cases may cause fatal heart, liver and kidney conditions.
Any Affecting Organs:
The infection quickly disseminates to the kidneys, lymph nodes, spleen, and bone marrow. Renal failure occurs as renal tubules undergo fatty change and eosinophilic degeneration, likely due to direct viral effect, hypotension, and hepatic involvement. The liver is the most important organ affected by yellow fever.
No specific treatment for the disease exists. Efforts focus on managing symptoms and limiting complications.
