A mosquito trap in San Marcos has tested positive for West Nile Virus. However, other reports indicate that West Nile Virus has also been detected in mosquito samples in various locations, including Atlanta's Grant Park neighborhood and Fulton County in Georgia, as well as in Connecticut and Texas cities such as Flower Mound and Arlington. The presence of West Nile Virus appears to have been confirmed in multiple areas, but the specific locations and details of the cases are not consistent across reports.
