The goal of the surveillance for West Nile Virus (WNV) is to describe the disease burden on the human population, track the geographic and seasonal trends of disease transmission, and communicate the risk of infection to the public.  Weekly Arboviral Summary Reports are generated and published during WNV season each year. 

More information about WNV and the current reporting and surveillance systems are included on the reports linked below. 

Reports for previous years are available here.
