Vector Surveillance

 
Each year, Environmental Health Service conducts vector surveillance activities on the installation to monitor mosquito/tick populations and disease prevalence.  A vector-borne disease of particular concern in the area is West Nile Virus.

 
West Nile Virus
 
West Nile Virus (WNV) is a flavivirus that can infect humans, birds, mosquitoes, horses, and other mammals.  The main route of transmission is through the bite of an infected mosquito.  West Nile virus can be a serious, even fatal, illness.  In Washington, the first cases of people becoming ill from West Nile virus were reported in 2006.
