IMPLEMENTATION OF A GEOSPATIAL SURVEILLANCE AND RESPONSE SYSTEM RESOURCE FOR VECTOR BORNE DISEASE IN THE AMERICAS (GEOHEALTH) WILL BE TESTED USING NASA SATELLITE DATA GEOGRAPHIC INFORMATION SYSTEMS AND ECOLOGICAL NICHE MODELING TO CHARACTERIZE THE ENVIRONMENTAL SUITABILITY AND POTENTIAL FOR SPREAD OF SELECTED ENDEMIC AND EPIZOOTIC VECTOR BORNE DISEASES. THE INITIAL FOCUS WILL BE ON DEVELOPING PROTOTYPE GEOSPATIAL MODELS ON VISCERAL LEISHMANIASIS AN EXPANDING ENDEMIC DISEASE IN LATIN AMERICA AND GEOSPATIAL MODELS FOR DENGUE AND OTHER AEDES AEGYPTI BORNE ARBOVIRUSES (ZIKA CHIKUNGUNYA) EMERGING ARBOVIRUSES THAT HAVE POTENTIAL FOR EPIZOOTIC SPREAD FROM LATIN AMERICA AND THE CARIBBEAN AND ESTABLISHMENT IN NORTH AMERICA. USE OF THE GEOSPATIAL SURVEILLANCE AND RESPONSE SYSTEM OPEN RESOURCE DATA BASES AND MODELS WILL BE MADE AVAILABLE WITH TRAINING COURSES TO OTHER INVESTIGATORS INTERESTED IN MAPPING AND MODELING OTHER VECTOR BORNE DISEASES. GEOHEALTH WILL BE A FULLY INTEROPERABLE PART OF GEOSS WITHIN THE PUBLIC HEALTH SOCIETAL BENEFIT AREA.
