We know the New Yawkers are good at scraping up bird poop. Mostly, they get it from their jet engines. Maybe the flu makes the buzzards seweecidal so they head straight for JFK? Two years? It took these poo pickers two years to write up a note about sick birds? That’s getting right on the problem! Or stepping in it?
A functioning immune system disposes of viruses through their lower alimentary.
If you checked your “deposit” today, you would find all sorts of lipid-envelope viruses; measles, mumps, chicken pox, polio, possibly smallpox.
It is the nature of the virus to replicate it self constantly.
Once immunity is achieved, these are captured by white blood cells and passed through the body without harms.
There is no reason not to believe that seagull immune systems work any differently.
I knew you’d catch that gem.
