Epidemiological Surveillance of Leishmaniasis in Montenegro, 1992-2013.

Introduction The diseases caused by Leishmania are spread worldwide and represent a significant public health problem. Objective The aim of this study was to present the results of epidemiological surveillance of leishmaniasis in humans in Montenegro in the period from 1992 to 2013. Methods The study was planned and realized as a descriptive epidemiological study. The sample included patients of leishmaniasis in Montenegro in the period from 1992 to 2013. The health and demographic data were collected from medical records. The disease was microbiologically proven in the patients. For statistical analysis the x(2)-test was used, which examined the significance of the incidence rate. Results During this period, 66 cases of leishmaniasis were identified (40 men and 26 women) aged 0 to 62 (mean 15.61 +/- 16.76 years). A visceral form of the disease was diagnosed in 65 (98%) patients, and one patient was diagnosed with cutaneous leishmaniasis. The average incidence rate for the above mentioned period is 0.48 per 100,000 inhabitants, The highest average incidence rate was identified in patients up to seven years of age (3.50 per 100,000 inhabitants). The highest average incidence rates of leishmaniasis were identified in the coastal region of Montenegro, while seasonal distribution indicates that the disease occurs throughout the year with predominance in late spring and summer. Conclusion The research has shown that Montenegro is among the countries with low incidence of leishmaniasis. Nevertheless, because of leishmaniasis re-emergence in the entire Mediterranean Basin, a comprehensive research of ecological and epidemiological characteristics of leishmaniasis, including better monitoring and notification system, is required.
