  1. 280 out of 406 patients displayed a positive result of laboratory investigations for parasitic infection
  2. aIf double positivity (direct examination and serology), then only the microscopy result was retained
  3. bif multiple helminthes infections were noted, then only one diagnostic was recorded per patient
  4. cif multiple positive results were noted (cross-reactions or multiple infections), then only the most prominent diagnostic was retained per patient
