Teen bats are spawning new viruses—here’s why scientists are paying close attention

New research from the University of Sydney sheds light on how coronaviruses emerge in bat populations, focusing on young bats as hotspots for infections and co-infections that may drive viral evolution. By analyzing thousands of samples over three years, scientists discovered that juvenile bats frequently host multiple coronaviruses simultaneously—offering a real-time window into how new strains might arise. These findings, while involving non-human-infecting viruses, provide a powerful model to forecast how dangerous variants could eventually spill over into humans, especially as environmental pressures bring bats closer to human habitats.
