A 10-year study was carried out to establish mosquito circulation and the prevalence of West Nile Virus on the Nevada National Security Site in south central Nevada. None of the insects checked were favorable for WNV although 2 examples, both Culiseta inornata, were suspect for WNV in 2005 and 2006, both from Well 3 Pond. Results from this study disclose patterns of mosquito distribution throughout the NNSS and suggest that NNSS workers have a really low threat of being subjected to WNV.

The effect of global climate change on contagious disease stays hotly discussed because several external and innate drivers communicate to influence transmission characteristics in nonlinear ways. We found that drought was the primary weather driver of increased West Nile virus upsurges, instead of within-season or winter season temperature levels, or rainfall separately. Local-scale data from one region recommended drought boosted epidemics using changes in mosquito infection frequency rather than insect abundance. We show that over the next 30 years, increased drought severity from climate change can triple West Nile virus situations, yet just in regions with low human immunity.
