Legionella

Desde su creación hasta la actualidad, La Unidad de Legionella tiene como principal función dar apoyo científico-técnico a la Administración General del Estado, a las Comunidades Autónomas y al Sistema Nacional de Salud en el campo de la prevención y control de la legionelosis, así como llevar a cabo investigaciones científicas en el contexto de la legionelosis. Además, la Unidad de Legionella también actúa como Laboratorio de Referencia de España frente al European Centre for Disease Prevention and Control (ECDC), siendo miembro de la red europea de vigilancia de la legionelosis, “European Legionnaires’ Disease Surveillance Network (ELDSNet). Finalmente, la unidad también realiza una actividad docente, participando en cursos de formación especializada, así como en Máster Universitarios.

 

Principales líneas de investigación
