Dr. David Knight, a cardiologist who performed much research on Heartworm disease when he was Chief of Cardiology at UPenn veterinary school, used
sophisticated weather maps and meteorological research of degree days to demonstrate the areas of the United States where Heartworm disease could be transmitted.
Using
sophisticated software, the students collect and examine data on the
weather — temperature, barometric pressure, and atmospheric chemistry — and are able to display and view the information in color - coded
maps and graphs that aid in understanding.
