Thousands of COVID-Like Cases With Animal Source Raise Risk of Future Pandemics

New Delhi: An study emphasising the ongoing pandemic threat from spillover events has established that hundreds of thousands of people may be infected annually by animals carrying coronaviruses related to the one that causes COVID-19 in China and Southeast Asia.

Most of the average 400,000 such infections that occur each year go unrecognised because they cause mild or no symptoms and aren’t easily transmitted between people, researchers with the EcoHealth Alliance and Singapore’s Duke-NUS Medical School said in a study released on Thursday before peer review and publication. Still, each spillover represents an opportunity for viral adaptation that could lead to a Covid-like outbreak, Bloomberg reported.
