Humans transmit more viruses to animals than vice versa, study finds

Many high-profile illnesses, such as COVID-19 and Ebola, originated from animals, leading to the perception that animals are dangerous. However, new research says this may not always be the case. After an analysis of viral genomes, researchers from University College London found a startling trend: humans are more likely to The study sheds light on how viral transmission works between humans and other vertebrate species. Zoonotic diseases originate in animals and jump to humans.

“We should consider humans just as one node in a vast network of hosts endlessly exchanging pathogens, rather than a sink for zoonotic bugs,” said Francois Balloux, a professor at the UCL Genetics Institute and co-author of the study. “By surveying and monitoring transmission of viruses between animals and humans, in either direction, we can better understand viral evolution and hopefully be more prepared for future outbreaks and epidemics of novel illnesses, while also aiding conservation efforts,” Professor Balloux added.
