Background: Cutaneous leishmaniasis is one of the most important infectious diseases in eastern Mediterranean countries. The aim of this study was to determine the epidemiological pattern of cutaneous leishmaniasis across a 10-year period in the Hamadan province. This study was considered necessary due to the lack of new information in recent years on the epidemiology of the disease.Methods: This is a descriptive study. The data of patients who were diagnosed with cutaneous leishmaniasis in Hamadan health centers were collected during 10 years (2007–2016) and were analyzed using SPSS software.Results: Of the 908 registered patients, 94% were male and 6% were female. The mean age was 32.7 ± 11.8. About 87.1% of patients had a history of travel to endemic areas. The highest incidence rate was observed in the year 2015 with a rate of 12.6, and the lowest was in 2008 at 1.5 per 100,000 people.Conclusion: Due to an increasing trend in the number of cutaneous leishmaniasis in Hamadan and the effect of occupation, high-risk groups such as lorry drivers should be informed of preventive measures such as using insect repellents. Also, considering the possibility of shaping a new hotspot in the province, thorough reviews and more comprehensive entomological studies are recommended.
L. major was considered the causative agent of leishmaniasis in the region, but the identification of a non-native L. tropica revealed the importance of further isolation of Leishmania parasites following molecular analyses and confirmation, and also revealed the importance of further isolation of Leishmania parasites from patients of the field areas who do not have easily access to health care centers for specialized treatment strategies.
Background: Leishmaniases are important diseases in many parts of the world, which are transmitted by bites of sand flies. Objectives: This study aimed at investigating some ecological aspects of sand flies in Hamadan. Materials and Methods: In this descriptive cross-sectional study, sand flies were collected weekly by sticky traps. Results: For this study, 3305 sand flies were collected and identified during 2013. Sand flies active season began from May till October in Hamadan. The greatest activity occurring between 08:00 pm till 12:00 pm. Conclusions: In order to avoid the possible transmission of diseases and reduction of harassments of sand flies, especially in the period of greatest activity, personal protection is recommended.
Aim:The present study was carried out to identify the Ixodidae ticks fauna of livestock and their seasonal activity in the cities of Boyer-Ahmad and Dena of Kohgiluyeh Province, south-west of Iran.Materials and Methods:Hard ticks from sheep, goats, and cattle were collected manually, stored in 70% ethanol, and identified using morphological characters.Results:During the study, a total of 1273 hard ticks from four genera, including Rhipicephalus, Hyalomma, Dermacentor, and Haemaphysalis, were collected. Rhipicephalus sanguineus (s.l.) had the highest frequencies in both cities with 62.08 and 62.88% of collected specimens, followed by Hyalomma scupense with 14.36 and 13.54% in Boyer-Ahmad and Dena, respectively. Furthermore, Hyalomma marginatum with only one sample or 0.12% of collected ticks showed the lowest frequencies in the studied areas. Dermacentor marginatus with three samples or 0.37% was recorded only in Boyer-Ahmad, and Haemaphysalis sulcata with two samples or 0.43% was recorded only in Dena. In both cities, sheep were the most infested ruminant, and the ears in sheep and goats were the most affected areas. The highest activity was observed in spring, and the lowest activity was observed in winter and autumn.Conclusion:The results of the present study showed that Hyalomma and Rhipicephalus genera were the most widespread genera in the study areas. Regarding the importance of genera, such as Rhipicephalus, Hyalomma, and Haemaphysalis, in transmitting disease agents and the location of Kohgiloyeh and Boyer-Ahmad Province in the routes of migrant birds, further studies are required to elucidate their exact roles in human and livestock health in these areas.
