Bird flu goes airborne after modification
A story in the New York Times reports that scientists are learning that avian flu has acquired airborne transmission ability after it was modified for increased strength. The experiments were part of studies to learn how the virus behaves. Now this virus can survive in the nose of ferrets, mammals whose nostril temperature is 4 degrees C cooler than a bird’s gut, where H5N1 usually grows.
The article points out that there’s a difference in ferret noses and those of us higher order mammals. One point cannot be smoothed out, however. The crossover point of animal to human is a step closer after this discovery. That kind of crossover is a prospect for triggering a pandemic.
