[Epidemiological Profile of 290 Cases of Human Cystic Echinococcosis Diagnosed in the Mustapha University Hospital (Algiers) from 2006 to 2011]

The Aim Of The Study: This study reports a series of 290 cases of hydatidosis confirmed by the surgery and/or the imagery with a positive immuno-diagnosis collected between 1st January 2006 and 31 March 2011 at parasitology-mycology laboratory of hospital university center of Mustapha of Algiers. Our aim is to specify, through the listed cases, the epidemiological aspects of this affection and compared with those obtained in two previous Algerian epidemiological investigations carried out, between 1963-1964 and 1966-1975.

Patients And Methods: It is a retrospective (2006-2008) and prospective (2008-2011) study. The parasitological diagnosis was carried out by the direct macroscopic and/or microscopic identification of the parasite and indirect diagnosis based on four techniques: passive hemagglutination, Elisa IgG "Echinococcus granulosus", Western Blot IgG "Echinococcus" and electrophoresis.

Results: The study shows that this affection is still prerogative of the young adult. It bring out also in this study that the child of school age (ten years), in particular the boy, pays a heavy tribute. At the child, the preferential pulmonary seat of the hydatic disease is not devoid of risk. At adult, this parasitic disease mainly affect the active woman.

Conclusion: Generally, the epidemiological and clinical characteristics join the endemic countries data and confirmed the row of our country among them. The transmission seems as strong as in the past, in spite of a much better social educational level.
