[Intestinal parasitosis among non-permanent resident students in Tunisia: a review of 23 years of monitoring in the department of Parasitology-Mycology at the Rabta Hospital of Tunisia].

Background: In order to fight digestive parasitism in Tunisia, a national program of surveillance of non-permanent resident students in Tunisia has been found to detect these parasitosis in this target population.
