Today I read about Yellow Fever
http://en.wikipedia.org/wiki/Yellow_feverYellow fever begins after an incubation period of three to six days.[11] Most cases only cause a mild infection with fever, headache, chills, back pain, loss of appetite, nausea, and vomiting.[12] In these cases the infection lasts only three to four days.
In fifteen percent of cases, however, sufferers enter a second, toxic phase of the disease with recurring fever, this time accompanied by jaundice due to liver damage, as well as abdominal pain. Bleeding in the mouth, the eyes, and the gastrointestinal tract will cause vomit containing blood (hence the Spanish name for yellow fever, vomito negro ("black vomit").[13] The toxic phase is fatal in approximately 20% of cases, making the overall fatality rate for the disease 3% (15% * 20%).[14] In severe epidemics, the mortality may exceed 50%.[15]
you bleed from all your soft tissues! Genitals! Eyes! Mouth! Butthole!
You puke up your stomach lining!
