Trends in Recently Emerged Leishmania donovani Induced Cutaneous Leishmaniasis, Sri Lanka, for the First 13 Years

الملخص EN

Sri Lanka reports a large epidemic of cutaneous leishmaniasis (CL) caused by an atypical L.

donovani while regional leishmaniasis elimination drive aims at achieving its targets in 2020.

Visceralization, mucotrophism, and CL associated poor treatment response were recently reported.

Long-term clinico-epidemiological trends (2001-2013) in this focus were examined for the first time.

Both constant and changing features were observed.

Sociodemographic patient characteristics that differ significantly from those of country profile, microchanges within CL profile, spatial expansion, constant biannual seasonal variation, and nondependency of clinical profile on age or gender were evident.

Classical CL remains the main clinical entity without clinical evidence for subsequent visceralization indicating presence of parasite strain variation.

These observations make a scientific platform for disease control preferably timed based on seasonal variation and highlights the importance of periodic and continued surveillance of clinic-epidemiological and other characteristics.
