In October 2022 the science writer David Quammen introduced me to the concept of viral chatter. At the time, scientists were expressing concern that an increasing number of mammals of different species were dying from bird flu. The term "viral chatter" was coined many years earlier by the infectious-disease researcher Donald Burke. It refers to the initial sporadic spread of a virus from wild animals to people. "It's a warning signal that's often recognized too late," Quammen wrote at the time. I've been thinking about the ways that the H5N1 has been chattering lately. It's spreading among dairy herds throughout the United States, and so far three farmworkers have been infected. It feels like yet another warning going largely unheeded. Today Quammen returns with a guest essay that argues for introspection when it comes to the current state of H5N1, specifically the ways in which Americans' demand for mass-produced and inexpensive dairy and meat has created an environment conducive to viral spillover. "We have surrounded ourselves with chattel animals, raised and milked and fattened and slaughtered and plucked and butchered in staggering numbers," he writes. "It's no surprise that sometimes they give us their viruses." As Quammen explains, there are reasons to be optimistic that H5N1 won't become a pandemic among humans. Though he adds that "nothing is certain about how an influenza virus will evolve until it happens." And right now the virus has too many opportunities to change than many experts are comfortable with. The virus is chattering. Will government bodies that can do something hear it?
