ABSTRACT
The authors present the results of blood and urinary parasitological check-up carried out among non resident students in Tunisia, between 1990 and 2006 in the laboratory of Parasitology-Mycology of la Rabta-s Hospital. It-s a retrospective study having interested 4016 foreign and Tunisian students having stayed in Africa [52%], in the Maghreb [26.64%], in the Middle East [15.91%], in the Far East [3.43%], in Europe [1.96%] and in America [0.05%]. Three parasitosisis were determined: malaria, urinary schistosomiasis and filariasis. One hundred twenty eight cases of malaria were diagnosed among 3476 blood smears and thick smears carried out. Plasmodium falciparum was found in 59 cases and Plasmodium malaria in 4 cases. The remaining 65 cases were of Plasmodium sp. Thirty eight cases of urinary schistosomiasis were diagnosed among 3932 urinary parasitological check-up. Eight cases of filariasis were found: 3 of Loa loa, 3 of Mansonella perstans and in the remaining 2 cases, we had a combination of these two micrifilariaes. In Tunisia, there has been no local transmission of malaria and urinary schistosomiasis since 1979 and 1984 respectively. Although these diseases had been eradicated, their re-emergence is not considered impossible. The authors insist on the necessity of systematic screening of these parasitosisis among non resident students in Tunisia as well as an early and effective treatment of the parasitic patients
