"Human Transmission of Viruses to Animals Outpaces Animal Transmission to Humans, Study Shows"
A study analyzing nearly 12 million virus genomes found that humans give more viruses to animals than animals give to humans, with 64% of human-to-animal transmissions involving pets, domesticated animals, birds, primates, and wild animals. The study highlights the significant impact of humans on the environment and animals, emphasizing the potential for viruses to jump between different species through close contact. Zoonotic diseases, such as COVID-19 and bird flu, pose a major threat due to the lack of pre-existing immunity in host species, with many pathogens circulating in humans having been acquired from animals at some point in time.
