  1. a: in brackets the percentages on 8,886 total patients are reported, calculated as the occurrence of the infections by protozoa and those by helminths in the population studied, not taking into account their involvement either in single or in mixed infections but considering the parasitoses (and subsequently the respective parasites involved) once at a time.
  2. b: in brackets the percent proportions of each group of patients calculated on the respective total are indicated.
