Infectious diseases and paediatric immunology

Malalties infeccioses i immunologia pediàtrica a Vall d'Hebron

The Infectious Pathology and Immunodeficiencies unit of Paediatrics is a hospitalisation unit dedicated to the study and treatment of these diseases in children, and also acts as a consultancy in the diagnosis and control of complex infections in immunosuppressed patients. It was created in January 1996 for the study and treatment of paediatric diseases of infectious origin, but over time, the increase in cases of children with infections, for various reasons, means the unit has taken over more functions to face new challenges.


In our Unit, we treat infants with infections and immunodeficiencies, a pathology that has become increasingly important in recent years. This increase in cases is due to several reasons, such as the emergence of AIDS, the emergence of almost forgotten pathogens, the importing of diseases from other geographical areas, the increase in opportunistic infections as a consequence of more aggressive treatments and more invasive diagnostic techniques, and the presence of new patterns of microbial resistance. This is in addition to the significant differences between treating children and adults. For this reason, our discipline is constantly being reviewed and updated, and is a key specialty for all hospital centres.

Our Unit was created in January 1996, as a hospitalisation unit dedicated to the study and treatment of paediatric illnesses of infectious origin, and in June 2004 it also incorporated the day hospital and the Outpatient Clinic for HIV and Primary Immunodeficiencies. A year later, at the initiative of the centre's management, it consolidated itself as a modern infectology unit, taking over consultation functions in the diagnosis and control of complex infection of critical and immunodepressed patients as well as patients from various paediatric specialties. We went on to incorporate the Outpatient Clinic for Infectious Community Diseases (contracted outside the hospital), Vertical Transmission Infections (from mother to child) and Pathologies, such as tropical diseases.
