Recent trends of cutaneous leishmaniasis in alert hospital, Addis Ababa

Background: Cutaneous leishmaniasis is endemic to many parts of the world and has re-emerged in a number of endemic countries in recent years. Environmental changes, immune status of the host and treatment failure are the three most important risk factors associated with the re-emerging and spread of Leishmaniasis. Cutaneous leishmaniasis (CL) ranges from localized, self-healing type to the disfiguring mucocutaneous and diffuse cutaneous type. Objective: To access the trend of CL patient flow in ALERT Hospital, Addis Ababa, Ethiopia. Methods: Patients' clinical and laboratory records were collected retrospectively for 1651 leishmaniasis suspected individuals from ALERT Hospital, from January 1, 2007 to December 30, 2010. Results: From the suspected individuals, 234 cases were positive for Leishmania species with Giemsa stain and/or histopathology and confirmed for CL, of whom 30 (12.8%) were diagnosed in 2007, 29 (12.4%) in 2008, 75 (32.1%) in 2009, and 100 (42.7%) were in 2010. Conclusions and recommendations: The overall proportion of cases with leishmaniasis among the suspected cases was 234/1651 (14.2%). The distribution of CL reports was higher for patients coming from Addis Ababa surrounding areas and Oromia region, 96/234 (41.03%) and 71/234 (30.34%), respectively. In general, the trend of leishmaniasis in and around Addis Ababa seems to be increasing,-which calls for further detailed epidemiological studies, including vector and reservoir host studies, to help in the prevention and control of the disease.
