2 Yellow Fever Yellow fever Yellow fever is a viral infection spread by mosquitoes. Causes, incidence, and risk factors Yellow fever is caused by a virus carried by mosquitoes. You can catch this disease if you are bitten by a mosquito infected with this virus. This disease is common in South America and in sub-Saharan Africa. Anyone can get yellow fever, but the elderly have a higher risk of severe infection. If a person is bitten by an infected mosquito, symptoms usually develop days later. In 1793 it was wrongly believed that it fever was contagious, meaning you could catch it from an infected individual.

3 Yellow Fever Yellow fever has three stages: Stage 1 (infection): Headache, muscle and joint aches, fever, flushing, loss of appetite, vomiting, and jaundice are common. Symptoms often go away briefly after about 3-4 days. Stage 2 (remission): Fever and other symptoms go away. Most people will recover at this stage, but others may get worse within 24 hours. Stage 3 (intoxication): Problems with many organs occur. This may include heart, liver, and kidney failure, bleeding disorders, seizures, coma, and delirium.

6 Philadelphia 1793 George Washington and other prominent officials left during the epidemic. Dr. Benjamin Rush attributed the cause of the Yellow Fever outbreak to coffee shipments rotting on the docks. Believed the Fever was contagious. Dr. Rush met with some success in treating Yellow Fever. One of his treatments involved “bleeding” a patient and having them ingest mercury. Both of these treatments were later discovered to be more dangerous than helpful.

7 Philadelphia 1793 African Americans were enlisted as volunteers to help the infected. It was believed at the time that African American were immune to Yellow Fever. Stephen Girard and Dr. Jean Deveze, disagreed with Dr. Rush’s treatments and came up with a different treatment. Deveze became the first leading specialist in treatment of Yellow Fever. Deveze proved that Yellow Fever is not contagious. Girard Avenue in Philadelphia is named after Stephen Girard for his work during the Yellow Fever epidemic.
