The outdoor temperature flirted with 100 degrees and heat advisories blanketed the region earlier this month as workers arrived at a commercial poultry operation in Weld County to start killing chickens.
Of the 1.8 million egg-laying hens inside the operation’s barns, at least some were infected with highly pathogenic avian influenza — bird flu. The strain of the virus that is now circling the globe has shown a remarkable ability to infect all kinds of animals, from seals to skunks to mountain lions. But it spreads most rapidly and lethally in wild birds and domestic poultry.
When a commercial flock is infected, standard practice is grim but efficient: Kill all the birds at the farm, devastating one operation in the hopes of stopping the virus and sparing the rest of the industry. By the time the workers in Weld County were done, though, some discovered that the virus had survived at least for one infection longer. It had found a new host: Their own bodies.
