Figure 4: Geography of worldwide occurrence of human cryptosporidiosis outbreaks and sporadic cases. A color-coded distribution of the main cases of cryptosporidosis reported in the literature during the last decade (1998–2008) for the entire population (adults and children) is here represented. Waterborne and foodborne diseases are represented by red and grey color, respectively. Spreading of the infection due to HIV immunological impairment is represented by green and travel-related disease by pink color. When not applicable the definition of waterborne and foodborne disease, the term community disease has been applied to person-to-person contacts and represented by a pale blue color. For countries characterised by two or three coexisting transmission modes, a double color-filling effect plus thick border lines have been used, consistently with the above reported code.
