There are two kinds of yellow fever which are spread by two different cycles of infection (Yellow pp). Jungle yellow fever is mainly a disease of monkeys that is spread from infected mosquitoes to monkeys in the tropical rain forest (Yellow pp). It is then spread to people who are bitten by mosquitoes that have been infected by monkeys (Yellow pp). Jungle yellow fever is rare and usually occurs in persons who work in tropical rain forests (Yellow pp). Urban yellow fever is a disease of humans and is spread by mosquitoes that have been infected by other people, usually by the aedes aegypti mosquito (Yellow pp).

These mosquitoes have adapted to living among humans in cities, towns, and villages and are known to breed in discarded tires, flower

During the early stages, yellow fever is difficult to recognize and can easily be mistaken for malaria, typhoid, rickettsial diseases, haemorrhagic viral fevers, arboviral infections, leptospirosis, viral hepatitis and poisoning, thus a laboratory analysis is needed to confirm a suspect case (Yellow-2 pp). Blood tests can detect yellow fever antibodies, and other techniques are used to identify the virus itself in blood specimens or liver tissue collected after death, however, these tests require highly trained laboratory staff using specialized equipment and materials (Yellow-2 pp).

There are approximately 200,000 cases of yellow fever, with 30,000 deaths, per year, yet due to underreporting, only a small percentage of these cases are identified (Yellow-2 pp). There is no specific treatment for yellow fever, however, dehydration and fever can be corrected with oral rehydration salts and paracetamol (Yellow-2 pp). Any superimposed bacterial infection should be treated with an appropriate antibiotic, and intensive supportive care may help the outcome for seriously ill patients (Yellow-2 pp).

pots, oil drums, and water storage containers close to human dwellings (Yellow pp). It was Walter Reed and his assistants James Carroll, Aristides Agramonte, and Jesse Jazear, while at experimental stations outside Havana, Cuba that proved the Aedes aegypti mosquito was the "vector" for the yellow fever virus (Yellow-3 pp). This work destroyed the popular myth that yellow fever was spread by direct contact with infected people or "contaminated" objects and thus, focused effor
