12 million viral genomes study finds humans transmit 64% of viruses from humans to animals.

Humans transmit more viruses to animals than they receive, according to a new study analyzing nearly 12 million viral genomes. Researchers found that humans were responsible for 64% of cases where viruses jumped from humans to animals, while the reverse occurred in 36% of instances. The study, published in Nature Ecology & Evolution, challenges conventional narratives and highlights the substantial role humans play in transmitting diseases.
