en Infectious diseases and public health Infectious diseases and public health Review article Review article Leishmaniases are tropical diseases caused by various types of intracellular protozoan species of the genus <em>Leishmania</em>. The infection is transmitted to vertebrate hosts by the infective bite of female sandflies. Depending on the location of the parasite in mammalian tissues and <em>Leishmania</em> species, leishmaniasis presents at least three primary clinical forms: visceral (VL), cutaneous (CL), and mucocutaneous (MCL). Iran is one of the significant endemic areas for CL in Asia. Here, we comprehensively reviewed the literature published from 2009 to 2019 and focused on the distribution, clinical aspects, causatives agents, reservoirs, and vectors of CL and VL in different parts of North Khorasan Province, northeast of Iran. North Khorasan Province in northeastern Iran is one of the principal foci of CL, but VL is just known as an endemic parasitic disease in some areas of this province. Based on a comprehensive literature search on studies published from 2009 to 2019, distribution, causatives agents, reservoirs, and vectors of CL and VL in different parts of North Khorasan Province were determined. Zoonotic cutaneous leishmaniasis <strong><span dir="RTL">)</span></strong>ZCL<strong><span dir="RTL">(</span></strong> due to <em>Leishmania</em> <em>major</em> is the main form of CL in this province. The principal animal reservoir hosts of the infection are rodents and <em>Ph. sergenti</em> is the most predominant species. VL, caused by <em>Leishmania infantum</em>, occurs in some parts of the province, and wild canines were confirmed as reservoirs.
