Human schistosomiasis is the parasitic disease with the highest morbidity and mortality worldwide after malaria. It is endemic in more than 78 tropical and subtropical countries, especially in sub-Saharan Africa, and it is estimated that 236 million people are infected. It can cause serious health complications at the genitourinary and hepatosplenic level, leading to the death of 300,000 people each year. The number of imported cases in Western countries has increased in recent years due to the arrival of a significant number of migrants from endemic regions and a growing number of travelers who have visited them. On the other hand, outbreaks of autochthonous transmission have recently been reported in Corsica (France) and Almería (Spain). For all these reasons, the European health authorities have recommended serological screening for the disease in all migrants from endemic areas who have been living in Europe for less than 5 years. Since Primary Care is usually the first point of contact for these people with the Health System, doctors must know the main aspects of the disease, and be provided with the necessary means for its diagnosis and treatment. This document has been prepared by professionals belonging to five scientific societies of Primary Care (SEMFyC, SEMG, SEMERGEN), Pediatrics (SEIP) and Tropical Medicine and International Health (SEMTSI), in order to establish clear recommendations for the diagnosis and management of schistosomiasis in Primary Care.

Esquistosomiasis; Cribado; Migrantes Schistosomiasis; Screening; Migrants Esquistosomiasi; Cribratge; Migrants La esquistosomiasis humana es la enfermedad parasitaria con mayor morbimortalidad a nivel mundial después de la malaria. Es endémica en más de 78 países tropicales y subtropicales, sobre todo de África Subsahariana, estimándose que 236 millones de personas están infectadas. Puede causar graves complicaciones de salud a nivel genitourinario y hepatoesplénico, llegando a ocasionar la muerte de 300.000 personas cada año. El número de casos importados en los países occidentales se ha ido incrementado en los últimos años debido a la llegada de un importante número de migrantes procedentes de regiones endémicas y de un creciente número de viajeros que han visitado las mismas. Por otro lado, recientemente se han comunicado brotes de transmisión autóctona en Córcega (Francia) y Almería (España). Por todos estos aspectos, las autoridades sanitarias europeas han recomendado el cribado serológico de la enfermedad en todas las personas migrantes procedentes de zonas endémicas y que lleven menos de 5 años en Europa. Dado que atención primaria es habitualmente el primer punto de contacto de estas personas con el sistema sanitario, los médicos deben conocer los principales aspectos de la enfermedad, y ser dotados de los medios necesarios para su diagnóstico y tratamiento. Este documento ha sido elaborado por profesionales pertenecientes a 5 sociedades científicas de atención primaria (SEMFyC, SEMG, SEMERGEN), Pediatría (SEIP) y Medicina Tropical y Salud Internacional (SEMTSI), con objeto de establecer unas recomendaciones claras para el diagnóstico y el manejo de la esquistosomiasis en atención primaria.
