Análisis del comportamiento epidemiológico de Leishmaniasis cutánea en Perú 2016-2021

Cutaneous leishmaniasis (CL) is an immune-mediated skin pathology caused mainly by Leishmania (L.) major, Leishmania tropica, Leishmania braziliensis, L. mexicana and L. amazonensis. The burden of CL in terms of disease and social stigma is concentrated in certain developing countries in Asia, Africa, and South America. People with asymptomatic CL represent a large proportion of infected individuals in endemic areas who do not have any lesions and can control the infection through mechanisms that are not fully understood. Currently, there is no approved prophylactic control measure for CL. This epidemiological report revealed that CL was prevalent in the Selva and Sierra geographic areas of Peru, while departments such as Ancash and La Libertad, coastal areas, were also involved in the reporting of cases in recent years. The pattern of CL cases reported in the different departments of the country had a very similar behavior in the period between 2016 and 2021, with the highest frequency of sick patients with skin lesions compatible and corroborated with CL predominating in the first 4 or 5 epidemiological weeks. The disease is endemic in many parts of the country, so more efforts and integrated approaches are needed to combat this pathology.
