 The World Health Organization has identified leishmaniosis as one of the eight major tropical parasitic diseases in the world. Every year, from 0.7 million to 1.3 million new cases of cutaneous leishmaniasis (CL) are registered in the world. Cutaneous leishmaniasis is still a great health problem in Iran. Of the total annual cases of leishmaniasis in Iran, about 80% are related to rural cutaneous leishmaniasis, 5% to visceral leishmaniasis and the rest are related to urban cutaneous leishmaniasis. this study aimed to investigate the epidemiological factors in patients with cutaneous leishmaniasis.

 A total of 2119 patients afflicted with cutaneous leishmaniosis due to skin lesions were examined. The data were analyzed after entering the data into SPSS software, vol 26. Tables and graphs were used for displaying the qualitative variables; central indicators and dispersion were used for indicating quantitative variables, and chi-square test was used for analyzing the data. The level of P ≤ 0.05 was considered as the level of significance.

 The mean age of 2119 patients was 28.32 ± 20.38 years. Furthermore, 65.2% of male patients and 34.8% of female ones were infected with the disease. As for the nationality of the patients, 81.8% of them were Iranians and 18.1% of them were Afghans, and 88.9% of them had a history of traveling to other areas. More than 51% of the cases occurred in the young age group, the age group of 21 to 30 years had the highest incidence (18.4%), and the incidence trend of the disease did not decrease. There was a statistically significant relationship between patients’ nationality and travel history, gender, and occupation (P = 0.0001). There was no statistically significant relationship between the incidence season and travel history (P = 0.221).

 Due to the patients’ travel to endemic areas, providing them with training on effective methods for preventing mosquito bites may have had a great impact on reducing the incidences of cutaneous leishmaniosis in travelers.

Different forms of leishmaniasis are important infectious diseases in Iran. While Rudbar County of Guilan Province has been introduced as a cutaneous leishmaniasis focus, there are few published data about the phlebotomine sand flies (Diptera: Psychodidae, Phlebotominae) of the province and their medical importance.

The present study is going to provide a review of sand fly-borne infections in Guilan Province and a checklist of sand flies of the province. Also, a note is presented on the name Sergentomyia murgabiensis sintoni.

Using the main databases such as Web of Science, PubMed, Scopus, Google Scholar, Scientific Information Database (SID), IranMedex and Magiran which were searched up to September 2022 and reviewing the literature, the available data about the sand fly-borne diseases of Iran and Guilan Province were extracted and analyzed.

In total, 11 species representing two genera of sand flies, Phlebotomus and Sergentomyia, are found in Guilan Province. The checklist and distribution of sand flies of the province have been provided. All species of the genus Phlebotomus in the province are proven or suspected vectors of leishmaniasis. Sand fly-borne leishmaniasis (cutaneous and visceral), sand fly fever and lizard leishmaniasis, which are among the endemic infections of the province, are discussed. Also, a taxonomic note is presented on the name Sergentomyia murgabiensis sintoni.

The prevalence of suspected or proven vectors of sand fly-borne diseases in Guilan Province is noteworthy. The study of the ecology of sand flies and detecting the exact vectors and reservoirs of leishmaniasis and phlebotomine fever by serological or molecular- specific tests in the province are recommended. Moreover, additional samplings of sand flies from localities, where have not been studied, are necessary.

Different forms of leishmaniasis are significant infectious diseases in Iran. While, Rudbar County of Guilan Province has been introduced as a new cutaneous leishmaniasis focus, there are few published data about the phlebotomine sand flies (Diptera: Psychodidae) of the province.

To study the phlebotomine fauna of Rudbar County, the sampling was performed in 12 collection sites by light traps, sticky traps and manual aspirators throughout August–December 2015. Sand flies were removed from the sticky traps, rinsed in acetone and stored in 80% ethanol along with the collections of light traps and hand catches.

In total, 2186 sand flies were collected and ten species representing two genera were morphologically identified: Phlebotomus (Adlerius) halepensis (0.27%), Ph. (Larroussius) kandeladii (0.10%), Ph. (Lar.) neglectus (0.91%), Ph. (Lar.) perfiliewi (53.88%), Ph. (Lar.) tobbi (43.45%), Ph. (Paraphlebotomus) sergenti (0.82%), Ph. (Phlebotomus) papatasi (0.10%), Sergentomyia (Parrotomyia) baghdadis (0.27%), Se. (Sintonius) clydei (0.05%) and Se. (Sin.) tiberiadis (0.10%). The species Ph. halepensis, Ph. neglectus, Ph. perfiliewi, Se. baghdadis, Se. clydei and Se. tiberiadis were reported for the first time in Guilan Province. This study also verified the presence of Ph. neglectus (Ph. major krimensis as a synonym and morphotype) in Iran. Moreover, the taxonomy of the subgenus Larroussius of the province was discussed.

The prevalence of suspected or proven cutaneous and visceral leishmaniasis vectors is noteworthy. The study of ecology of sand flies and detecting the exact vectors of leishmaniasis and phlebotomine fever by molecular specific tests in Guilan Province are recommended.
