West Nile virus kills birds of many species and can cause fatal encephalitis (inflammation of the brain) in humans and horses. The virus was first isolated in Africa (where it is thought to be endemic) in the 1930 s, and by the 1990 s it had been found throughout much of Eurasia. West Nile virus was not found in North America until 1999 (when it was first detected in New York), but since that time it has spread rapidly across most of the United States. Use the phylogenetic tree of West Nile virus isolates shown below to construct a hypothesis about the origin of the virus lineage that was introduced into the United States. The isolates are identified by their place and date of isolation.
Which of the following statements about West Nile Virus and the current epidemic (Zika Virus) is true? Group of answer choices Zika is spread to humans by mosquitos while West Nile is spread by crows There is no vaccine or treatment for both Zika virus and West Nile Virus Both Zika and West Nile are endemic to the Middle East Both West Nile Virus and Zika virus are associated with birth defects

Vaccines for viral diseases were discovered prior to the discovery of viruses. How was this possible? Explain in detail. (2pts) Baltimore's classification is a way of classifying viruses. How are they classified? West Nile Virus is transmitted by mosquitos and has an enveloped structure. In addition, it has an +ssRNA genome that is not segmented. Based on this information, what is Baltimore's classification of this virus? (2pts)
