West Nile Virus was first described in which region and introduced to the United States in what year?

Explanation:
West Nile virus is a mosquito-borne flavivirus. It was first described in Uganda during the 1930s (often cited as 1937). It later entered the United States in 1999, with an outbreak centered in New York City, marking its first appearance in the Western Hemisphere. The other statements don’t fit because the virus is transmitted by mosquitoes (not only by bats), and the cited year and location correctly describe the actual introduction timeline rather than a broad or inaccurate spread description.
