By partnering with West Nile virus surveillance labs across the country, the WestNile 4K Project is planning to sequence more than 4,000 virus genomes to reconstruct a high definition picture of West Nile virus spread and evolution during the last 20 years in the United States. The data that they generate will be immediately released and, along with other entomological data, will be used to uncover local transmission dynamics. As little progress has been made in effectively controlling West Nile virus outbreaks since its emergence, their goal is to use fine-scale transmission networks revealed through virus genomics to better design targeted control measures.


Below is a table showing the number of sequenced genomes by state.
