V.                 Identify the organism found in the area of the world as designated by the numbers on the

world map.  Name the country or a country found within the designated areas. The organisms are not restricted to only those areas designated on the map. Identify one epidemiology factor which increases the parasite’s  incidence.  (15 points)
