Leishmaniasis in Sri Lanka: A Research Review has presented a unique and interesting scientific problem; Leishmania donovani-induced cutaneous leishmaniasis (CL). This new clinical entity is increasingly reported in many countries at present. This book presents the story of leishmaniasis in Sri Lanka through the author’s 20-year experience. Through its comprehensive 13 chapters, book sheds crucial light on the past, present, and future of leishmaniasis on the island while covering historical aspects, progression in research on parasite, vector, host, immunology, clinical, diagnostic, treatment, patient care, and their corresponding trends The content builds gradually to a final discussion of the gaps in knowledge, research needs, capacity building and a model to manage an emerging health issue in a country. This concise yet comprehensive book is an ideal thought-provoking reference guide to professionals with a keen interest in the field of leishmaniasis.
Key Features
• Provides a comprehensive and complete resource on leishmaniasis, including various aspects of the disease, distilling credible information from available literature coupled with historical references.
• Follows a model approach for handling emerging infectious diseases for the benefit of clinicians and front-line workers.
• Discusses the unique problem of skin localizing visceralizing parasites of Leishmania and provides basic principles of management for other infectious diseases and vector-borne infections.
