Figure 2

West Nile virus viremia profiles in American Crows that were mosquito-exposed (n=8), orally exposed by ingestion of sparrow carcasses (n=5), or contact-exposed (n=4). A fifth contact-exposed crow developed an ephemeral low-titered viremia (102.2/mL serum) and was treated as an outlier in this analysis. Error bars show standard deviation of log10-transformed viremia titers.
