The present-day epidemic of avian influenza has killed about 58 million birds in the U.S. as of February. Pursuing on the heels of the COVID-19 pandemic, significant outbreaks of viruses like chook flu increase the specter of another disease jumping from animals into people. This approach is identified as spillover.
I’m a veterinarian and a researcher who reports how conditions spread among animals and persons. I was on the Colorado Condition College veterinary diagnostic crew that assisted detect some of the earliest circumstances of H5N1 avian influenza in U.S. birds in 2022. As this year’s outbreak of fowl flu grows, people today are understandably fearful about spillover.
