Leishmaniasis is a rather neglected but increasingly common disease in specific regions of the world where the vector thrives and the human population vulnerable to leishmaniasis. The clinical presentation and ultimately the diagnosis of leishmaniasis should be done in time to avoid fatalities from complications of the disease. Healthcare teachers deployed to work in busy healthcare institutions and learners under their instruction require quick reference material to guide in diagnosis and management of leishmaniasis. The relevant information is rarely found from a single book or other source of information. The main objective of this book is to avail the summarized essential details to enable the readers save on time while searching for relevant information required for pathophysiology, clinical presentation, complications, diagnosis and management of leishmaniasis. The book also provides insights into background information essential for contemporary research efforts towards the prevention of leishmaniasis.
