Epidemiological Trends of Cutaneous Leishmaniasis in Al-Madinah Al-Munawarah Province, Western Region of Saudi Arabia

Objective: To investigate the epidemiological trends of cutaneous leishmaniasis (CL) in Al-Madinah Al-Munawarah, western region of KSA. Materials and Methods: Four hundred and sixty-seven parasitologically confirmed CL cases attending Al-Meeqat Hospital, Al-Madinah, during 2012-2015, were included in this study. Results: Both Saudi and non-Saudi nationals were infected, with the highest infection rate being among Saudis (68.7%). Males were more affected than females as 86.9% of the total CL cases were males. Moreover, CL was prevalent in all age groups with higher frequency among young adults and adolescents (23.1% and 22.7%, respectively). Interestingly, almost all the patients in the adolescent and child age groups were Saudis (96.2% and 93.5%, respectively). Considering geographical distribution, the highest percentage of the cases (40.5%) were from the northern parts of Al-Madinah province while the eastern parts reported the least infection rate (7.3%). Few cases (2.5%) were supposed to encounter the infection abroad. Additionally, the frequency of infection was found to follow a seasonal distribution. Regarding treatment, pentostam, ketoconazole, or cryotherapy were the treatment options usually used. Conclusion: CL is prevalent in Al-Madinah Al-Munawarah area and new foci are being introduced. Thus, detailed studies with large surveillances regarding vector and reservoir hosts in and around the area are needed.
