Yellow Fever

About

• Yellow fever is an acute viral haemorrhagic disease transmitted by infected mosquitoes.
• The "yellow" in the name refers to the jaundice that affects some patients.

Causes and risk factors

• A flavivirus causes yellow fever.
• It is transmitted by mosquito bite, usually the Aedes aegypti mosquito.
• The mosquito becomes infected by biting an infected human or a monkey.
• An infected mosquito is a source of infection for the rest of its life.
• The flavivirus is endemic among monkeys that live in the tree tops of the jungle, known as the jungle canopy, in many parts of Africa and the Americas.

Symptoms

• Symptoms of yellow fever include fever, headache, jaundice, muscle pain, nausea, vomiting, fatigue, jaundice, which gives the skin and whites of the eyes a yellow tinge, kidney failure, liver failure, hemorrhage, bleeding from the nose, mouth, and eyes.
• Between 20 percent and 50 percent of people who develop toxic stage symptoms die within two weeks.

Treatment

• There is no effective antiviral medication to treat yellow fever, so treatment consists of supportive care in a hospital.
• This includes providing fluids, oxygen, making sure blood pressure is adequate, replacing lost blood, kidney dialysis if there is kidney failure, and treating any secondary infections.

Prevention

• In the middle of the 20th century, scientists developed a safe and effective vaccine that prevents yellow fever.
