Objective: To analyze the incidence of intestinal protozooses from the results of stool examinations of patients from Teresina-PI and map the positive results, according to species, sex, age and affected area. Methods: It was a documentary study with a quantitative approach of a descriptive and retrospective nature, in which the temporal distribution of cases of intestinal protozooses in the population in Teresina-PI, from January to September 2018, was contemplated through the collection stool exam results from a public municipal reference laboratory. Results: It was observed that, of a total of 23694 parasitological examinations of feces, 8.43% were positive for protozoa, with females being the most affected (61.76%). As for the most affected area, 67.27% were from urban areas. Among the age groups, the prevalence was higher between 1 to 10 years (25.58%) and 11 to 20 years (19.72%). Regarding the most prevalent species of protozoa, three represent 96% of the affected cases, which are: Entamoeba coli (33.93%), Entamoeba histolytica (36.69%) and Giardia lamblia (25.53%).
