Who knows? But Hershel sure as hell would have had the infection in his whole system, zombie bites him, Saliva enters blood stream, the infection from the saliva spreads through his system where I assume it would attach itself to blood cells if it is indeed caused by that, or it just lies dormant and when they did it takes over.
He was in trauma, his heart rate would have increased dramatically, the blood would be circulating his body a lot quicker, the infection would have hit his heart and circulated round his systems many times over. Average is about a minute to circulate the body at resting, during stress, exercise, trauma it would pump through the body faster. How long did it take Rick to cut off his leg again 10-20 minutes?
Hershel should have been dead anyway from the shoddy amputation.
About the other things, like Jim surviving if he had proper care to his wound, maybe he would have survived, what everybody is infected with is most likely an airborne fungal infection, which probably explains why some people who died didn't turn because they were not in the open air to be infected by it.
These fungal infections exist today and live in a host and take over power of the host for a limited time once it has died.
Also do you remember the scene where Andrea stabbed a walker and got a spatter of blood in her eye? Surely that would cause an infection what's the difference between a bit of saliva and a spatter of blood? They both would have entered the bloodstream.
Either way it's fiction everyone can make there own theories because they left the show so open.
