Community Acquired Respiratory Viral Infections (CARV)
Community acquired respiratory viral infections (CARV) pose a continuous threat to public health worldwide. Rapid and reliable diagnosis of CARV is crucial e.g. for case detection, patient management, and prognostic appreciation. The SARS-CoV-2 pandemic impressively demonstrated the importance of diagnostic tools to contain the pandemic. We aim to develop, evaluate and use novel diagnostic tools for clinical practice, epidemiological studies (Figure 1, Dähne et al., J Clin Virol 2024), and translational research. Our ultimate goal is to translate our research into clinical practice and to provide evidence-based recommendations.
To achieve this, we collaborate with multiple clinical partners both locally and externally as well as with hospital hygiene. Specifically, we have a longstanding collaboration with the German community acquired pneumonia network CAPNETZ. Within this network, we serve as the virological reference laboratory and provide expert diagnostic support for multiple ongoing studies, e.g. the BUrden of Disease and COst of illneSS for RSV and other pathogens among Hospitalized adults (BUCOSS Hosp).
