  3. 3. Urban Yellow Fever <ul><li>There are two different types of yellow fever.

Yellow fever can spread by coughing, sneezing, breathing, and handshaking. </li></ul><ul><li>2. Back then, people who died from yellow fever were thrown out on the streets, this made the city even more contaminated and more people were likely to get ill. </li></ul>
  4. 4. Sylvatic (or Jungle) Yellow Fever <ul><li>Disease of monkeys </li></ul><ul><li>Starts when the mosquito bites a monkey and starts to spread </li></ul><ul><li>People get infected when they are in the middle of this natural cycle and are bitten by mosquitos that have been infected by monkeys. </li></ul><ul><li>It occurs in tropical Central and South America. </li></ul><ul><li>It occurs mainly among adult males 20 to 40 years old who are exposed in the tropical forests </li></ul>
  5. 5. Symptoms of Yellow Fever <ul><li>After a victim is struck with the fever, symptoms start to show after three to six days. The time period of this is called the incubation period. Mild Yellow Fever symptoms include fever, headache, bloody nose, nausea, and slow heartbeat. There are about three stages to these symptoms.

  9. 9. THE BONE TINGLING EPIDEMICS <ul><li>New York City-1690, 1803 </li></ul><ul><li>Philadelphia-1793-1798 </li></ul><ul><li>New Orleans-1847, 1878 </li></ul><ul><li>Corpus Christi TX-1867 </li></ul><ul><li>Jacksonville, FL-1888 </li></ul><ul><li>Cuba-1898 </li></ul>Yellow fever is one of the most tragic diseases in history.

  10. 10. Treatments back then <ul><li>In 1793, treatments weren’t nearly as advanced as they are today. A sign of yellow fever was black blood. Victims were bled because doctors believed letting out all of the black blood in the infected body would get rid of the virus. </li></ul>
  11. 11. Preventions <ul><li>To prevent yellow fever, avoid mosquito bites in tropical areas. Also, use insect repellant, protective clothing, and vaccination. The vaccination for this virus is called Stamaril. </li></ul>
  12. 12. Vaccination The vaccination for this virus is called Stamaril. When a vaccine enters your body, the vaccine holds a tiny portioin of the virus itself. Your body then fights off the small amount of the virus. This makes your body know how to fight off the whole virus if it ever comes back into your body. It is recommended for all people ages 9 months or older traveling to or living in areas in Africa, South America, and other areas where yellow fever is still active. For example if you are traveling to South America and you haven’t had your vaccination they won’t let you in.
  13. 13. Interesting Facts <ul><li>After the 1800’s yellow fever was hard to catch. There are a few reasons why this may have happened. </li></ul><ul><ul><li>1. People who had yellow fever can develop life long immunity so they don’t get yellow fever ever again. </li></ul></ul><ul><ul><li>2. A vaccine was developed </li></ul></ul><ul><ul><li>3. People who survived would never get it again </li></ul></ul><ul><ul><li>4. Some realized that bleeding did not help to cure yellow fever. </li></ul></ul>
