YELLOW FEVER

Yellow Fever is an acute RNA viral infection caused by the virus Flaviviridae. It is indigenous to equatorial regions of Africa and South America where mosquitos are the most common vector of transmition. Though there is an effective vaccine against Yellow Fever, many people in the 3rd world countries affected by the illness do not have access to modern health care and, thus, remain succeptible to infection.

The CDC has stated that severe cases of Yellow Fever have a mortality rate of between 15-50%, while the World Health Organization has stated that 15% of those infected with Yellow Fever, enter a "toxic phase" and that 50% of those who enter toxicity die.

The symptoms of Yellow Fever begin 3 to 5 days after the pathogen has entered the body. Symptoms begin suddenly with headache and fever. Sometimes those are the only symptoms that appear, and the disease goes into latency without causing any damage.

About 15% of the infected progress to the toxic phase which includes fever, chills, vomiting, hemoraging, jaundice (from which the disease gets its name) and slow heartbeat. After 3 days in the toxic phase, the disease enters a brief period of remission in which the patient feels a bit better. However, the disease returns with a vengeance in its final stage causing characteristic black vomiting as the victim internally hemorages.

Due to its high mortality and painful symtoms this sick gets a
