C 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.
