The contagious, fatal illness in deer, elk and moose must be taken seriously, say experts as it takes hold in the US and reaches other countries. While it has not infected humans yet, the risk is growing
Summary
Chronic wasting disease (CWD), an incurable and fatal prion disease affecting deer, elk, moose, and reindeer, is spreading across 36 US states and other countries.
Scientists warn of a potential human spillover crisis, with tens of thousands likely consuming infected venison. Experts criticize labeling it "zombie deer disease" as it downplays the threat.
Concerns include contamination through carcass transport and feedgrounds. Calls grow for better surveillance and prevention, but conflicting policies and resistance to reducing wildlife feedgrounds hinder efforts.
Temperatures of more than 1,100 degrees Fahrenheit — sometimes up to 1,800 degrees
A combination of heat — about 275 degrees Fahrenheit — and bursts of unimaginably high pressure — over 100,000 psi — showed promise in reducing prion infectivity, at least in processed meats like hot dogs
Infected material is placed in a solution of potassium hydroxide — also known as caustic potash — for at least six hours, at 300 degrees Fahrenheit and 60 psi, about four times ambient air pressure.
Bacteria and viruses are not much of a threat, our immune systems have been battling them for our entire evolutionary history. Every now and then one comes along and does a whole bunch of damage, but overall we come out on top.
Mammals haven't really had to worry about fungus, we are too hot and there hasn't been a forcing factor to make fungus evolve temperature resistance, till recently. We don't have any defense against fungal infection; the temperature barrier has always kept us safe.
Global warming is forcing fungal evolution, our temperature barrier is shrinking, at some point in the not too distant future, there will be a major outbreak of a fungal disease.
The climate has been significantly warmer in the past than it is projected to become even in the worst-case near-future scenario. This won't be some unprecedented opportunity for fungal parasites.
