“…In contrast to the epidemic period (Amarir et al., ), our results suggest that in the endemic period (2013–2015), there were no difference in the number of CL cases detected between different age groups. The predominance of CL cases in women compared to men usually described in Moroccan foci (Kahime, Laamrani‐El Idrissi, Nhammi, & Boumezzough, ) was not present in the age group under 20 years. This higher rate of infection among women older than 20 years should still be attributed to the lack of medical care of men who give less importance than women and young people to the aesthetic appearance (Kahime et al., ) or are busier working to go to the health centre.…”

On the other hand, even during the hot season, women stay evenings at home significantly more than men, as shown by the survey performed (odds ratio= 2.079, IC95% 1.065–4.056, p ‐value = 0.032), what might lead to a greater contact with the vector in the housings.…”

“…In Morocco, the epidemiology of leishmaniasis caused by L. tropica has not been fully elucidated. CL due to this Leishmania species seems to increase and tends to extend into nonendemic areas, in contrast to CL due to L. major or L. infantum (Kahime et al., ). The disease is often described as anthroponotic and affects both rural and urban populations (Kahime et al., ; Rhajaoui et al., ).…”

Cutaneous leishmaniasis (CL) caused by Leishmania tropica is emerging in new areas, initially as outbreaks and then establishing endemic foci. There is little evidence of the risk factors and effectiveness of existing control measures, what limits our ability to generalize in different epidemiological settings. The disease is described as anthroponotic; however, zoonotic outbreaks have been reported in some countries. Our aim was to identify risk factors in a recently reported endemic focus in Morocco in order to design more effective control programmes. A case-control study was conducted from September 2014 to October 2015 for epidemiological data collection from families with and without CL cases. Sandflies were captured and L. tropica infection determined. The presence of potential animal reservoirs was evaluated. 71 CL cases (44 diagnosed between 2013 and 2015) and 137 healthy people were surveyed. The average age of the new cases was 33.1 ± 22.3 years, and 69.0% were women. Phlebotomus sergenti was the most abundant species with a density of 4.27 sandflies/trap/night and differences between houses with and without CL cases were detected (p-value = 0.014). Overall, 2.7% female P. sergenti and 3.0% dogs were positive for L. tropica. Human, cat, rabbit and bird blood was detected in blood-fed P. sergenti females. 45% people used preventive measures that were not translated into a reduction in the individual risk of acquiring CL. Exposure to P. sergenti was the only risk factor found, and the reduction in its density could be achieved through the improvement of water wells management, organic fertilizers' disposal and dogs control. The lack of effectiveness of indoor residual spraying and treated nets are attributable to poor compliance and misuse of them. In addition, result optimization of the awareness campaigns on the public is possible by involving patients with CL to explain their own experience.

Bilgisayar tabanlı çalışan CBS, araştırmacıların vektör kaynaklı hastalıklar, çevresel faktörler ve vektör eklembacaklıları arasındaki ilişkileri içeren risk haritaları üretmesini sağlar (3)(4)(5).

ÖZ Amaç: Çalışmamızda, Mersin ilinde 2005-2015 yılları arasında rapor edilen 630 yerli kutanöz leishmaniasis (KL) hastasının lokasyon bilgileri ile biyoklimatik ve çevresel değişkenler kullanılarak hastalığın günümüzdeki tahmini dağılımını gösteren ekolojik niş modelinin üretilmesi amaçlanmıştır. Yöntemler: Ekolojik niş modeli, hasta lokasyonları ile coğrafi bilgi sistemleri ve maksimum entropi veritabanına girilen biyoiklimsel ve çevresel değişkenlerin yorumlanması esasına dayalı olarak üretilmiştir. Bulgular: Mersin ili için üretilen modelde, eğri altındaki alan değeri (AUC) 0,918 olarak hesaplanmıştır. Ayrıca KL hastalığının dağılımına en etkili olan klimatik faktörler; en kurak çeyreğin ortalama sıcaklığı (BIO9), en sıcak çeyreğin ortalama sıcaklığı (BIO10) ve en sıcak ayın maksimum sıcaklığı (BIO5) olarak belirlenmiştir. Sonuç: Mersin'de kutanöz leishmaniasis hastalığının dağılımı ile iklimsel faktörler arasında bir ilişki söz konusudur. Üretilen model, sağlık bakanlığı yetkililerine vektör kaynaklı hastalıkların kontrolünde ve epidemiyolojilerinin daha iyi anlaşılmasında katkı sağlayacaktır. Anahtar Kelimeler: Kutanöz Leishmaniasis, ekolojik niş modellemesi, coğrafi bilgi sistemleri, maksimum entropi, Mersin ABSTRACT Objective: In our study, we aimed to develop an ecological niche model showing current distribution of cutaneous leishmaniasis (CL) by using location information on 630 cases of CL reported in the Mersin province between 2005 and 2015 and bioclimatic and environmental variables. Methods: The ecological niche model was based on interpretation of patient locations and climatic data entered in geographical information systems and maximum entropy databases.Results: In the model produced for the Mersin province, the area under the curve was calculated as 0.918. Also, the mean temperature of the driest quarter (BIO9), mean temperature of the warmest quarter (BIO10), and maximum temperature of the warmest month (BIO5) were determined as climatic factors that are most effective for CL distribution. Conclusion: There is a relationship between distribution of CL and climatic factors in the Mersin province. The developed model will contribute to better understanding of epidemiology and control of vector-borne diseases by authorities in the ministry of health.
