Epidemiology conducts research on health and disease at the population level – infection epidemiology is concerned with contagious diseases. Their tools and methods are systematic queries, clinical examinations and laboratory diagnostic documentation for both healthy and afflicted individuals, as well as statistical analysis of the compiled data. Causes and risk factors for infections can thus be identified. Infectious diseases epidemiology contributes to the development of preventive measures, early detection and therapy for diseases. Moreover, it examines the efficacy of such measures. Thus epidemiology ties in with scientific findings in basic research as well as medicine, and examines these processes at the population level.


Prof Dr Gérard Krause

With the help of epidemiology we analyze the impact of pathogens on the entire population. We can detect the occurrence of infectious diseases at an early stage and develop measures  to protect people from infections. Furthermore, we can determine how effective certain measures are.

Gérard Krause studied medicine at the University of Mainz and completed his third state examination in human medicine in 1993. During this time, he also received a research doctorate in tropical hygiene from the University of Heidelberg. From 1993 to 1998 he worked as a physician and research associate in the field of tropical hygiene, internal medicine and hospital hygiene at the University Clinic Freiburg. He then went on to work as an epidemic intelligence service officer at the Centres for Disease Control and prevention in Atlanta, USA. He also completed various research and training residencies in England, Ecuador, Colombia, Burkina Faso and Niger.

In 2000 he moved to the Robert Koch Institute in Berlin (RKI) as head of the srveillance unit. In the following years he acquired the medial board certification in hygiene and environmental medicine with an additional qualification in tropical and rescue medicine. He was director oft he department of infectious disease epidemiology at the RKI from 2005 to 2013. Gérard Krause received the habilitation and lectorship in Epidemiology and Hygiene at the Charité Uniersity Medicine in Berlin in 2005 where he also founded the Masters of Science Programme for Applied Epidemiology in 2008.

In 2011, Gérard Krause he accepted the position as full professor (W3) for infectious disease epidemiology at the Medical University Hannover (MHH) and head of the department of epidemiology at the HZI, Braunschweig. In 2013 he founded the PhD Programme "Epidemiology" at the MHH.  

Gérard Krause is a member of the Scientific Advisory Boards of the Bernhard Nocht Institute, Hamburg, the National Reference Centers for Human Medicine Microbiology in Belgium and the Institut de Veille Sanitaire in France. 



  • SORMAS - the future of epidemic surveillance

    Epidemiologists and IT experts from Germany and Nigeria have jointly developed an innovative app to help fight epidemics like ebola or cholera - the Surveillance Outbreak Response Management and Analysis System (SORMAS). This video explains why a tool like SORMAS is urgently needed and introduces the unique approach that makes SORMAS so powerful.

  • Staphylococcus aureus – ein Leben in der Nase2000 zufällig ausgewählte Braunschweiger Bürger haben in diesem Juni Post vom HZI erhalten – mit der Bitte, an einer Studie über die Verbreitung von Staphylococcus aureus teilzunehmen. Varianten des Bakteriums sind unter dem Kürzel MRSA als Krankenhauskeime zu trauriger Berühmtheit gelangt. Unsere Wissenschaftler wollen nun erforschen, wie viele Gesunde – außerhalb von Krankenhäusern – mit diesem Keim Leben. Und sie suchen nach Risikofaktoren, die Staphylococcus aureus die Besiedlung des Menschen erleichtern. Begleiten Sie Frank Pessler und Jaishri Mehraj ein Stück in die Welt der Epidemiologie...
  • Proben und Fragebögen für die Infektionsforschung - Die Nationale Kohorte Diabetes mellitus, Krebs, Arterienverkalkung und diverse Infektionen sind Volkskrankheiten, über die wir viel zu wenig wissen. Mit der Nationalen Kohorte wollen Wissenschaftler diesen Krankheiten auf den Grund gehen und neue Strategien gegen sie entwickeln. Frank Pessler und Manas Akmatov nehmen die Infektionen ins Visier. Lassen Sie sich erklären, wie ihnen 225.000 Menschen dabei helfen sollen…
