The Erasmus MC is committed to a healthy population and excellence in healthcare through research and education ( The Department of Viroscience of the Erasmus MC ( runs an extensive experimental research program on the epidemiology, pathogenesis, prevention and treatment of infections by human and animal viruses. The research groups of Prof R. Fouchier and Dr. B. van den Hoogen are focused on the molecular biology and evolution of (respiratory) viruses in humans and animals.

Within the group of Prof. Fouchier, studies on viral zoonoses and virus transmission are performed to understand viral pathogenesis and the emergence of pandemic strains, with the aim to improve preparedness. Additional research on adaptive and innate immune responses and influenza virus antigenic drift is conducted with the aim to improve vaccination strategies.

Within the group of Dr. van den Hoogen, studies on the interaction of human metapneumovirus and respiratory syncytial virus with the immune system are conducted with the aim to design novel antiviral therapies. These basic research lines are continuously supported by the development of novel assays in molecular biology, virology, genetics, and bioinformatics.
