Virginia has a lot of mosquitos, and if you live in a wooded area near Ashland, you are at risk of bites, especially during the summer months. Mosquitos can spread West Nile Virus, Easter equine encephalitis, La Crosse encephalitis, and St. Louis encephalitis. There have also been cases of Zika here in Virginia. But, all cases of Zika since 2016 have been related to travel outside the United States.
