How come they don’t get sick?
Did you worry about the pangolins when it came out that they might have been the critters that transmitted SARS-CoV‑2 to humans? Fear not!
It turns out that viral infections don’t both pangolins. Why? No clue. But they’re missing the kind of anti-viral defenses that most other animals have.
“Our work shows that pangolins have survived through millions of years of evolution without a type of antiviral defense that is used by all other mammals. Further studies of pangolins will uncover how they manage to survive viral infections, and this might help to devise new treatment strategies for people with viral infections.”
