New viruses on the horizon

Suddenly they appear and - like the SARS-CoV-2 coronavirus - can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics. This is suggested by current genetic analyses carried out by an international team of researchers. Virologists from the German Cancer Research Center (DKFZ) were in charge of the large-scale study.

Original Title: New viruses on the horizon - like the SARS-CoV-2 - may trigger major epidemics. Scientists discovered 40 previously unknown nidoviruses in vertebrates from fish to rodents, including 13 coronaviruses. In host animals infected with different viruses, a recombination of viral genes can occur.
