Swine flu, Ebola, SARS and now Covid-19 - all these infectious diseases originated in animals and are so-called zoonoses. But how is it that pathogens cross the species barrier and jump from animals to humans?
Scientific studies show that humans, with their lifestyle, are significantly involved in the emergence of new pandemics. Environmental degradation, climate change, globalisation, increasing population density, the consumption of wild animal meat and factory farming facilitate the emergence of zoonoses.
Originally, humans and animals lived peacefully together with a whole range of pathogens to which they adapted in the course of their evolution. However, disturbed environmental conditions are constantly opening up new possibilities for contact and transmission.
For Simone Sommer, an expert in zoonoses, it is clear that species, environmental and climate protection must be given greater priority - not least in the interests of our own health.
Prof. Simone Sommer is the director of the Institute of Evolutionary Ecology and Conservation Genomics at the University of Ulm. Research stays have already taken her to Madagascar, Namibia, South Africa, the USA, Brazil and Panama.
