Abstract

Background objectives: Leishmaniasis is caused by various species of Leishmania. Approximately 20 of them are pathogenic to mammals. In Sri Lanka, cutaneous leishmaniasis (CL) is an established vector-borne disease. CL originates and spreads mainly through sand fly bite in many endemic countries. Objective of the present study was to compare the geographical distribution and demographic features of CL cases in 2014 and 2016 in Hambantota district, Sri Lanka.

Methods: The patients who were presented to the Tangalle Base Hospital from June to December in 2014 and 2016 were examined and a descriptive study was carried out using a structured-questionnaire. Slit -skin smears were collected from each patient, Giemsa-stained and examined under the light microscope to identify Leishmania amastigotes.

Results: Out of 256 and 314 suspected CL patients, 156 and 155 were identified positive for the year 2014 and 2016 respectively. Out of 12 District Secretary Divisions in the Hambantota district, highest number of CL cases, 85 and 86 was reported from Tangalle DSD in 2014 and 2016 respectively. Number of identified CL patients in Beliatta DSD had increased from 50 to 67 during the study period. In both years, majority of the CL patients were ≥ 50 years old with males more infected than females. Although CL association with occupations were insignificant, housewives were the highly (23%) infected occupants in this area.

Interpretation conclusion: Based on present findings, geographical distribution within DSDs in Hambantota district had changed. It emphasizes the importance of CL as a health problem in Hambantota district.

皮肤利什曼病的分布变化：斯里兰卡汉班托塔的疾病传播风险推测。

背景目标：利什曼病是由多种利什曼原虫引起的。其中约有 20 种对哺乳动物具有致病性。在斯里兰卡，皮肤利什曼病（CL）已成为一种病媒传播疾病。在许多利什曼病流行的国家，利什曼病主要通过沙蝇叮咬传播。本研究旨在比较 2014 年和 2016 年斯里兰卡汉班托塔地区 CL 病例的地理分布和人口特征：方法：对2014年和2016年6月至12月在坦加勒基地医院就诊的患者进行了检查，并使用结构化问卷进行了描述性研究。收集每位患者的裂隙皮肤涂片，用吉氏涂片染色并在光学显微镜下进行检查，以确定利什曼原虫：在 256 名和 314 名疑似利什曼病患者中，2014 年和 2016 年分别有 156 名和 155 名患者被确定为阳性。在汉班托塔区的12个区委书记分区中，2014年和2016年丹加勒区委书记分区报告的CL病例数最多，分别为85例和86例。在研究期间，贝里亚塔区委书记分区已确认的慢性淋巴细胞白血病患者人数从 50 人增至 67 人。在这两年中，大多数CL患者的年龄≥50岁，男性感染者多于女性。虽然CL与职业的关系并不显著，但家庭主妇是该地区感染率较高的职业（23%）：根据目前的研究结果，汉班托塔地区膳食营养不良者的地理分布发生了变化。这强调了CL作为健康问题在汉班托塔地区的重要性。
