I remain stunned at how poorly we are responding to the threat from H5N1. Our poor response to COVID was regrettable but perhaps understandable given the US hadn’t faced a major pandemic in decades. Having been through COVID, however, you would think that we would be primed. But no. Instead of acting aggressively to stop the spread in cows we took a gamble that avian flu would fizzle out. It didn’t. California dairy herds are now so awash in flu that California has declared a state of emergency. Hundreds of herds across the United States have been infected.
I don’t think we are getting a good picture of what is happening to the cows because we don’t like to look too closely at our food supply. But I reported in September what farmers were saying:
The cows were lethargic and didn’t move. Water consumption dropped from 40 gallons to 5 gallons a day. He gave his cows aspirin twice a day, increased the amount of water they were getting and gave injections of vitamins for three days.
Five percent of the herd had to be culled.
“They didn’t want to get up, they didn’t want to drink, and they got very dehydrated,” Brearley said, adding that his crew worked around the clock to treat nearly 300 cows twice a day. “There is no time to think about testing when it hits. You have to treat it. You have sick cows, and that’s our job is to take care of them.”
Here’s another report from a vet:
…the scale of the farmers’ efforts to treat the sick cows stunned him. They showed videos of systems they built to hydrate hundreds of cattle at once. In 14-hour shifts, dairy workers pumped gallons of electrolyte-rich fluids into ailing cows through metal tubes inserted into the esophagus.
“It was like watching a field hospital on an active battlefront treating hundreds of wounded soldiers,” he said.
Here’s Reuters:
Cows in California are dying at much higher rates from bird flu than in other affected states, industry and veterinary experts said, and some carcasses have been left rotting in the sun as rendering plants struggle to process all the dead animals.
…Infected herds in California are seeing mortality rates as high as 15% or 20%, compared to 2% in other states, said Keith Poulsen, a veterinarian and director of the Wisconsin Veterinary Diagnostic Laboratory who has researched bird flu.
The California Department of Food and Agriculture did not respond to questions about the mortality rate from bird flu.
Does this remind you of anything? Must we wait until the human morgues are overrun?
The case fatality rate for cows appears to be low but significant, perhaps 2%. A small number of pigs have also been infected. On the other hand, over 100 million chickens, turkeys and ducks have been killed or culled.
There have now been 66 cases in humans in the US. Moreover, the CDC reports that in at least one case the virus appears to have evolved within its human host to become more infectious. We don’t know that for sure but it’s not good news. Recall that in theory a single mutation will make the virus much more capable of infecting humans.
When I wrote on December 1 that A Bird Flu Pandemic Would Be One of the Most Foreseeable Catastrophes in History Manifold Markets was predicting a 9% probability of greater than 1 million US human cases in 2025. Today the prediction is at 20%.
Once again, we may get lucky and that is still the way to bet but only the weak rely on luck. Strong civilizations don’t pray for luck. They crush the bugs. So far, we are not doing that.
Happy new year.
