Opinion: A Bird Flu Pandemic Would Be One of the Most Foreseeable Catastrophes in History

Almost five years after Covid blew into our lives, the main thing standing between us and the next global pandemic is luck. And with the advent of flu season, that luck may well be running out.

The H5N1 avian flu, having mutated its way across species, is raging out of control among the nation’s cattle, infecting roughly a third of the dairy herds in California alone. Farmworkers have so far avoided tragedy, as the virus has not yet acquired the genetic tools to spread among humans. But seasonal flu will vastly increase the chances of that outcome. As the colder weather drives us all indoors to our poorly ventilated houses and workplaces, we will be undertaking an extraordinary gamble that the nation is in no way prepared for.

All that would be more than bad enough, but we face these threats gravely hobbled by the Biden administration’s failure — one might even say refusal — to respond adequately to this disease or to prepare us for viral outbreaks that may follow. And the United States just registered its first known case of an exceptionally severe strain of mpox.

As bad as the Biden administration has been on pandemic prevention, of course, it’s about to be replaced by something far worse. Robert F. Kennedy Jr., Donald Trump’s pick to lead the nation’s vast public health agency, has already stated he would not prioritize research or vaccine distribution were we to face another pandemic. Kennedy may even be hastening its arrival through his advocacy for raw milk, which can carry high levels of the H5N1 virus and is considered a possible vector for its transmission.

We might be fine. Viruses don’t always manage to adapt to new species, despite all the opportunities. But if there is a bird flu pandemic soon, it will be among the most foreseeable catastrophes in history.

Devastating influenza pandemics arise throughout the ages because the virus is always looking for a way in, shape shifting to jump among species in ever novel forms. Flu viruses have a special trick: If two different types infect the same host — a farmworker with regular flu who also gets H5N1 from a cow — they can swap whole segments of their RNA, potentially creating an entirely new and deadly virus that has the ability to spread among humans. It’s likely that the 1918 influenza pandemic, for example, started as a flu virus of avian origin that passed through a pig in eastern Kansas. From there it likely infected its first human victim before circling the globe on a deadly journey that killed more people than World War I.
