26. Yellow Fever
Yellow fever isn’t a syndrome but rather a hemorrhagic infection typically transmitted through mosquitoes. It causes a high fever, bleeding under the skin, and cell death of the liver and kidneys. Because of this, the first sign of the infection is jaundice, which is the eyes’ whites and the skin’s overall color becoming yellow. The main treatment options for someone with yellow fever include supportive care to minimize liver and kidney damage, dealing with the high fever, and reducing blood loss.

Thankfully, there are immunizations against yellow fever, which are essential if you plan on traveling. In fact, some countries require that you be vaccinated against it before allowing you in. If someone becomes infected, they are generally immune, so they are unlikely to become infected again. Most of those who become infected usually do not develop symptoms, which typically appear between three to six days after infection.
