Research area

Research into the epidemiology of food- and waterborne and zoonotic infections. Our research aim to improve our understanding of how and to which degree these diseases are transmitted to people and cause outbreaks – with the overall aim of hopefully being able to devise ways to reduce the infection pressure. The methods are analyses of surveillance data, register data, questionnaire data, data from outbreaks in addition to geographical and microbiological data. We try to be active within most of the many diseases we work with – but with a particular focus on the very frequent (Campylobacter and Salmonella) and serious (Listeria and STEC). From 2019 also research into various aspects of COVID-19.
