Tokat ilinde yaşayan insanlardaki kene tutunma bölgelerinin değerlendirilmesi

Amaç: Bu çalışmada, Türkiye’de Kırım Kongo Kanamalı Ateşi (KKKA) açısından endemik olan bir bölgede kene enfestastonu olan kişilerin demografik özelliklerinin ve kenelerin tutunma bölgelerinin değerlendirilmesi amaçlanmıştır. Yöntem: 2009 yılında Tokat ilinde 5,089 kişi kene enfestasyonu şikayeti ile hastanelere başvurmuştur. Kene tutunması olan her hasta için sağlık personelleri tarafından doldurulan hastaların isim, yaş, cinsiyet, meslek, tarih, yaşadığı alan, seyahat bilgisi ve ek notları içeren standart formlar incelenmiştir. Kene tutunma bölgeleri karın, kollar, koltuk altı, sırt, göğüs, baş ve boyun, kalça, bacaklar ve perine olmak üzere 9 gruba, hastaların yaşları da 0-9, 10-19, 20-39, 40-64 ve ≥65 olmak üzere 5 gruba ayrılarak incelenmiştir. Bulgular: Başvuran kişilerin büyük bir kısmında (n=1,051, %23,3) kenelerin bacaklara tutunduğu tespit edilmiştir. 20-39 yaş grubundaki kişiler (n=1.228, %27,24) kene tutunması oranının en yüksek olduğu grup olarak belirlenmiştir. Hastalardan 2.825 (%62,67)’inin erkek, 1.683 (%37,33)’ının kadın olduğu tespit edilmiştir. Ayrıca, 2.740 (%60.78) hastanın kırsal alanlarda, 1.768 (%39,22) hastanın kentsel alanlarda yaşadığı belirlenmiştir. İnsanlar üzerinden toplanan kenelerin tür teşhisleri yapıldığında, örneklerin Argas (1 tür), Dermacentor (2 tür), Haemaphysalis (3 tür ve 1 alttür), Hyalomma (4 tür), Ixodes (5 tür) ve Rhipicephalus (4 tür) cinsleri içerisinde toplam 20 taksona ait olduğu belirlenmiştir. Sonuç: Bu çalışmayla birlikte, KKKA endemik Tokat bölgesinde kene enfestasyonu olan hastaların demografik özellikleri ve kenelerin tutunma bölgeleri ilk kez değerlendirilmiştir. Ayrıca, Türkiye’de insanların Argas vespertilionis ve Ixodes gibbosus türü keneler tarafından enfeste edildikleri ilk kez tespit edilmiştir.

Tick attachment sites in humans living in the Tokat province of Turkey

Objective: The aim of this study was to evaluate the attachment sites of ticks and the demographic properties of patient infested by ticks in Tokat province, a Crimean-Congo hemorrhagic fever (CCHF) endemic region in Turkey.Methods: In 2009, 5,089 patients with tick bites admitted to hospitals of Tokat province. A standard questionnaire, including the name, age, gender, profession, date, living area, and travel history of patients, was filled by health personals for each patient with a tick bite. Attachment sites of ticks were divided into 9 groups: abdomen, arms, axilla, back, chest, head and neck, hip, legs, and perineum, while the age-group of patients were as follows: 0-9, 10-19, 20-39, 40-64 and ≥65.Results: The majority of the patients applied (n=1,051, 23.3%) were found ticks on the legs of them. 20-39 year age group tick-infested were the highest proportion (n=1228, 27.24%), while 2,825 (62.67%) of patients were male, and 1,683 (37.33%) were female. In addition, it was determined that 2,740 (60.78%) of patients were living in rural, while 1,768 (39.22%) were living in urban areas. A total of 20 tick taxa were identified, comprising 6 genera: Argas (1 species), Dermacentor (2 species), Haemaphysalis (3 species and 1 subspecies), Hyalomma (4 species), Ixodes (5 species) and Rhipicephalus (4 species). Conclusion: In the present study, attachment sites of ticks and the demographic properties of patients were evaluated for the first time in Tokat province, a CCHF endemic region. In addition, it was reported people infestations by argas vespertilionis and Ixodes gibbosus ticks for the first time in Turkey.
