The Virology Section offers rapid, specific, sensitive diagnosis of viral infection, by combining the most modern technology with traditional tests that remain the reference standards in virology, and by maximum automation of the processes involved.
Based on the techniques used, the activity is structured in:

  • Automated serology
  • Manual serology
  • Direct antigen detection in pathologic products
  • Cell cultures
  • Molecular biology, using qualitative and quantitative techniques for nucleic acid amplification
  • Sequencing methods to detect antiviral resistance mutations


We use more than 80 markers in the diagnosis, follow-up, prognosis, and evaluation of treatment efficacy in viral infections, enabling detection of up to 35 different viruses.

In the public health setting, we are the reference laboratory for:

  • Acute respiratory infections of viral etiology in the Daily Information Plan for Acute Respiratory Infections in Catalonia (PIDIRAC, Pla d'Informació Diària de les Infeccions Respiratòries Agudes a Catalunya) of the Department of Health of the Regional Government of Catalonia (Generalitat de Catalunya).
  • Eradication programs for measles, mumps, and rubella, coordinated by the General Directorate of Public Health of the Regional Government of Catalonia (Generalitat de Catalunya), and hepatitis A and B virus seroprevalence studies in the Catalan population.
  • Surveillance and diagnosis of arboviruses and other imported viruses in Catalonia.

In addition, the Virology Section is the Spanish Influenza Center for the WHO’s Global Influenza Surveillance Network (GISN), performing surveillance for epidemic and pandemic infection by influenza viruses in our country.

We are also a part of the Community Network of Reference Laboratories (CNRL) for Human Influenza in Europe, under the auspices of the European Center for Disease Prevention and Control (ECDC).


Our research activity is mainly centered on transferring the knowledge acquired in virology to the clinical setting in the following areas:

  • New pathogens and new methods for diagnosing viral respiratory infection
  • Markers for the diagnosis and follow-up of herpesvirus and polyomavirus infection in immunosuppressed patients
  • Viral infection in travelers
  • Pathogenesis of hepatitis B and C virus
  • Mechanisms of antiviral drug resistance in HIV, cytomegalovirus, influenza virus, and hepatitis virus 


We participate in training resident physicians (MIRs) of the Microbiology and Parasitology Specialty, and in undergraduate and postgraduate medical teaching in the Faculty of Medicine of the UB. We also welcome residents from other hospitals, as well as specialists and licensed physicians from Spain and other countries, who wish to broaden their education.
