Hepatitis C (hepacivirus)The rest are ArbovirusSt. Louis Envephalititis VirusWest Nile VirusYellow Fever VirusDengue Virus

3

What are the Togavirus?

RubellaTwo Arbovirus:Western Equine Encephalitis VirusEastern Equine Encephalitis Virus

4

Compare the symptoms of...St. Lois EncephalitisWest Nile VirusYellow Fever VirusDengue Virus

**Both: St. Lois Encephalitis and West Nile Virus cause Fever, Malaise, Encephalitis, paralysis, coma, and death**Yellow Fever Virus causes: fever, Nausea, Jaundice, hemorrhage, Black Vomit**Dengue Virus causes: fever, headache, muscle and joint pain, rash... if hemorrhagic kind then vomit blood, hemorrhage, and shock

5

Compare the transmission of...St. Lois EncephalitisWest Nile VirusYellow Fever VirusDengue Virus

**Both St. Lois Encephalitis and West Nile Virus use mosquitos and birds; humans are dead end**Both Yellow Fever Virus and Dengue Virus use mosquitos (aides aegypti); humans and primates are a vector.**Yellow fever also travels through "tree mosquitos" and monkeys
