In serious situations, or left untreated, yellow fever can become a nightmare disease. Besides the notable jaundice that it cause, the disease can quickly cause organ problems and bleeding throughout the body. Unsurprisingly, all these symptoms can lead to death.
To make things worse, the mosquito-borne illness is hard to diagnose. It’s often confused with other diseases and can go without confirmation until it’s too late. Once a person is bitten and has the virus in their system, they are not contagious to other people, but since yellow fever mimics other illnesses, it’s often overlooked.
