But as far as anyone can tell, humans can’t spread it. The virus has remained a true “bird” flu, tailored to attach to avian cells, not invade human throats and noses, where coughing and sneezing reliably spew droplets. Under the right conditions, however, that could change. A single mutation could give the bird flu a foothold in people and spark a pandemic that experts fear could be deadlier than COVID-19.
