"Human Transmission: The Surprising Source of Animal Pandemic Threats"

A study from University College London suggests that humans pass on more viruses to animals than they catch from them, highlighting the potential for human-to-animal virus transmission to spark health crises. The research analyzed tens of thousands of viral genomes and found that almost two-thirds of the samples were transmitted to animals via humans. This human-to-animal virus transmission could pose a conservation threat to species and impact food security. The study emphasizes the need to monitor and understand viral evolution to better prepare for future outbreaks and epidemics. The origins of the Covid-19 virus remain a subject of debate, with theories ranging from natural origins at a Wuhan market to a potential lab leak.
