West Nile virus (WNV) is a potentially life-threatening illness spread through the bites of infected mosquitoes (Huang et al., 2019). WNV has been active in California since 2003 after its introduction to the United States. WNV currently occurs sporadically in Monterey county according to the California department of public health. Neighboring counties have shown a considerably higher abundance of WNV activity. Transient bird species provide a vector for WNV to move from one population to another and as such there is potential for WNV to become a more serious threat to the Monterey peninsula. By understanding the factors which impact WNV and its transmission a municipality such as the city of pacific grove may develop an action plan to combat yearly mosquito fluctuations and a protocol in the event of a WNV surge.
