[Investigation of Leishmania infantum Seroprevalance and Leishmaniasis Knowledge Level in Northern Cyprus].

Leishmaniasis is an infectious disease caused by Leishmania parasites, transmitted by sand flies and common in the Mediterranean region. Cyprus is located in the east of Mediterranean Sea and is considered endemic for Leishmaniasis. In our study, it was aimed to investigate Leishmania infantum IgG seropositivity in healthy volunteers living in different regions of Northern Cyprus and to determine the risk factors for Leishmaniasis and measure the level of public knowledge about the disease. A total of 300 healthy volunteers (farmer/livestock: 100, hunter: 100, control group: 100) from five different regions of Northern Cyprus were included in the study, including Nicosia, Kyrenia, Famagusta, Morphou/Lefka, and Trikomo/Karpasia. The participants' blood was drawn and prepared questionnaire forms were filled out. Collected blood was centrifuged and the serum samples were separated and stored at -80ºC until the day of the test. All serum samples were tested for L.infantum IgG specific antibodies using the ELISA method (NovaTec, Immundiagnostica GmbH, Germany) in accordance with the manufacturer's recommendations. L.infantum IgG positivity was found to be 4.7% (14/300). The mean ages of L.infantum IgG positive and negative participants were 43.64 ± 11.74 and 42.17 ± 14.32 respectively. There was no statistically significant relationship between seropositivity and age (p= 0.706). The positivity rate was found to be significantly higher in hunters and farmers/livestocks compared with the control group (p= 0.020). In addition, it was determined that having a dog and the number of dogs owned were significantly associated with Leishmaniasis (p= 0.017, p= 0.020, respectively). On the other hand, 77% (231/300) of the volunteers included in our study had no prior knowledge about the disease. When compared to the other study groups, it was determined that hunters had the most knowledge of the Leishmaniasis infection (p= 0.001). Moreover, it was observed that as the education level of the participants increased, the level of knowledge about the disease also increased in parallel (p≤ 0.001). According to the results in our study, L.infantum IgG seropositivity was undeniably high in the healthy population living in Northern Cyprus. It is clear that outdoor activities such as hunting or dealing with farming/livestock are risk factors for the disease. In this context, it is apparent that more clear results will be obtained about the prevalence of the disease with the conduction of large-scale epidemiological studies. As a result, we concluded that especially risk groups should be informed about the current status of Leishmaniasis infection and necessary precautions should be taken.
