4. What is the National Companion Animal Surveillance Program (NCASP) NCASP is a national, near real-time, surveillance system that uses the electronic medical records of pet animals seen at >560 veterinary hospitals in the U.S. to detect events that signal the threat of an emerging infection, a terrorist threat, or a natural disaster, for people living in the same geographic area NCASP is a national, near real-time, surveillance system that uses the electronic medical records of pet animals seen at >560 veterinary hospitals in the U.S. to detect events that signal the threat of an emerging infection, a terrorist threat, or a natural disaster, for people living in the same geographic area Supported by a grant from the CDC Supported by a grant from the CDC

5. Mission of the National Companion Animal Surveillance Program Provide real-time and near-real-time information on syndromic and disease events that occur among species of pet animals in the United States Provide real-time and near-real-time information on syndromic and disease events that occur among species of pet animals in the United States Conduct detailed statistical analyses to identify space-time clusters of events and characterize host and environmental risk factors Conduct detailed statistical analyses to identify space-time clusters of events and characterize host and environmental risk factors Alert to the occurrence of potential acts of bioterrorism, emerging zoonoses, and toxic chemical exposures Alert to the occurrence of potential acts of bioterrorism, emerging zoonoses, and toxic chemical exposures Serve as a sentinel for the occurrence of environmentally related diseases (e.g.., cancer) Serve as a sentinel for the occurrence of environmentally related diseases (e.g.., cancer)

31. Summary The National Companion Animal Surveillance System provides complementary syndromic surveillance capability to the more traditional use of human hospital records to detect acts of bioterrorism, emerging infections, and to study health effects resulting from natural and man made disasters such as floods, hurricanes, and accidental chemical releases into the environment The National Companion Animal Surveillance System provides complementary syndromic surveillance capability to the more traditional use of human hospital records to detect acts of bioterrorism, emerging infections, and to study health effects resulting from natural and man made disasters such as floods, hurricanes, and accidental chemical releases into the environment

32. Summary-con’t The success of parallel animal and human syndromic surveillance ultimately depends on development of better statistical and visual methods to identify correlations between temporal and spatial changes in syndrome frequency in humans and animals and better communication between ALL health care providers The success of parallel animal and human syndromic surveillance ultimately depends on development of better statistical and visual methods to identify correlations between temporal and spatial changes in syndrome frequency in humans and animals and better communication between ALL health care providers
