Dear colleagues: We seek your assistance in obtaining any data relating to the incidence of mosquito-borne viral diseases in wild cetacean or other marine mammal populations. Two specific diseases of particular interest include West Nile Virus and St. Louis Encephalitis. We are looking for any data associated with possible exposure to such viruses based on climate, species and environment (e.g. coastal species and tropical environments). We would appreciate any data and insights, which can be directed to courtney.vail@wdcs.org<mailto:courtney.vail@wdcs.org> Sincere regards, Courtney Vail WDCS Dr. John Jett Stetson University Dr. Jeff Ventre University of New Orleans
