Unit 17: Influenza and Other Respiratory Viruses
- Head:
- Thorsten Wolff
- Deputy:
- Ralf Dürrwald
The unit is responsible for the surveillance of and research into influenza viruses and other major respiratory viral pathogens in Germany. The virological surveillance of circulating influenza viruses is carried out by the National Reference Centre for Influenza, which is part of the unit, within the framework of the National German Influenza Working Group. Every year up to 5,000 samples from patients with influenza-like illness are investigated here, which are sent by the sentinel network of general practitioners and paediatricians. The samples are also being investigated on a routine basis also for the presence of respiratory syncytial virus, human metapneumovirus, adenovirus and rhino/entoroviruses. Diagnostic typing/subtypings, sequencing and antigenic characterisation of circulating viruses enable a rapid detection of antigenic drift variants and mutant viruses resistant against licensed antiviral agents. Furthermore, the unit conducts complementary molecular virological studies to investigate the viral gene functions that control the virulence, tropism and host specificity of human and animal pathogenic influenza viruses. A specific focus is on the contribution of host factors of virus propagation and viral mechanisms that sabotage innate immune defences. The activities of the unit are integrated into the European Influenza Surveillance Network (EISN) and support the annual vaccine recommendations by WHO. At the same time they contribute to a better understanding of viral pathogens and the derivation of new strategies for the prophylaxis and therapy of respiratory virus diseases.
