• Wide variety of Hosts/Vectors– Birds, Mosquitoes, Horses, Humans, and

various other mammals

• Variety of institutions involved in reporting

• Medium in which data is reported

The GPRMC WNV Tracking System

• Online Database that consolidates regional data for mosquitoes, birds, horses, sentinel chickens, humans, and others

• Developed by GPRMC Information Management and Preventive Medicine

Purpose

• To provide timely dissemination of information relating to all positive cases of West Nile Virus within the Great Plains Regional Medical Command

• To provide an estimate of installation workload

Lessons Learned

• Great program + poor compliance = useless system

• Components of a good system– Scalable to changing needs– Multiple platform interface capabilities – Include GIS mapping capabilities– Differentiation between trapping methods

Conclusions

• Standardization across all DoD entities

• Surveillance and reporting compliance

• Communication, Communication, Communication!
