utaneous Leishmaniasis (CL) caused by

Leishmania

donovani

is a vector borne disease in Sri Lanka with a

rising trend in prevalence. Identifying risk factors and specific

clinical presentations to implement preventive strategies and

early treatment is the objective of this study. A sample of 509

clinically suspected of having CL was selected consecutively

from 2005 to 2015 across Sri Lanka for the study. Diagnosis

was confirmed by microscopic visualization of the

Leishmania amastigote from the slit skin smear. A structured

questionnaire was used to identify the exposure related risk

factors and a clinical examination was done to identify the

lesion characteristics. Out of 509 clinical cases, 41.5% were

smear positive. The study population ranged from ages 1

to 80 (mean = 34.46) and the most affected age group was

30-39. Of the smear positives, 58.85% were males while many

were from the North Western and North Central regions of

the country and exposed to scrub jungles. Sand fly exposure

(p=0.04) and risk occupations (p=0.04) were significant risk

factors. Signs of inflammation (p=0.02), lack of pruritus

(p=0.02) and scaly lesions (p=0.003) were significant lesion

characteristics in smear positivity. Lesions were commonly

found in the face and upper limbs and were papulo-nodular

in nature. Overall smear positivity among clinically suspected

CL was at 41.5%. Significant risk factors for the disease were

high risk occupations and sand fly exposure. Lack of pruritus,

presence of scaly lesions and signs of inflammation were

highly predictive lesion characteristics of CL in Sri Lanka.
