Why has the SARS-CoV-2 virus ravaged the global human population, but many other animal viruses haven’t? Using nematode worms as a model, researchers at Penn State conducted a set of experiments to investigate the factors influencing the disease outcomes of virus spillover events. They found that the species of the host influences whether a virus will take off in a new population. For example, some species never get infected, while others become infected and readily transmit the virus to other individuals within the species.
