Yellow plague:

Yellow fever ( Yellow jack,Xellow plague,Bronze john,Black vomit,Yellow jack viral disease )

Yellow fever is an infectious disease caused by a virus, which is transmitted via mosquitoes is subtropical and tropical areas (especially in sub-Saharan Africa and in the Amazon Basin). It can cause very serious conditions and even lead to death, especially in adults. It appears with flu-like symptoms: fever, nausea, and aches. In rare cases, patients may develop inflammation of the liver (hepatitis), which can cause jaundice (icterus), as well as cause blood clotting disorders with increased proneness to bleeding, which can be fatal. The World Health Organisation recommends a vaccination when travelling to affected areas.

Full Description

The yellow fever virus exists in Africa and South America, mainly in monkeys, but it can also be transmitted to humans by mosquitoes. After 3 to 6 days (incubation period) the disease breaks out, typically in three stages. It can be observed, that children only show mild symptoms, while the disease often processes severely or fatal (mortality rate up to 50%) in adults.

Medical Conditions

In the first stage of the disease, the symptoms are similar to flu, with sudden, very high fever (40°C), chills, headache and muscle aches, nausea and vomiting and conjunctivitis of the eye. In stage two (day 3 to 4), the fever drops and the symptoms decrease. The disease will now either heal or develop into stage three. In this stage, the fever rises again and organs will be damaged, with liver and kidney failure and bleedings inside the gastrointestinal tract or into the skin. The combination of blood loss and fever often causes a circulatory shock.


A treatment of the cause, which would be killing the virus, does not exist. It is only possible, to treat the patients in an intensive care unit to relieve the symptoms and to balance out the loss of liquids. Even though, the adult mortality rate lies between 20% and 50%. It is therefore highly recommended to find out about a vaccination recommendation before travelling to tropical countries. As this might be necessary for other diseases as well, and because especially the yellow fever vaccination requires certain waiting periods between other vaccinations, you should plan your vaccinations as early as possible.
