The short answer: No. While hunting accidents do happen, they are far less frequent than most people seem to fear. The difference is that they tend to be much more sensational than your regular run-of-the-mill gang shooting or robbery at gunpoint, dozens of which happen frequently enough that they're hardly even considered newsworthy anymore. In fact, even web sites devoted to the eradication of sport hunting, like C.A.S.H. (The Committee to Abolish Sport Hunting) can only come up with a very small number of incidents to build the case that it is dangerous to be in the woods during hunting season. Compared to the number of motor vehicle or household accidents, it is more dangerous to use common household cleaners than it is to go hiking in November.
Even so, there are a couple things anyone can do in the interest of putting safety first. It's always good to know the hunting regulations for the area you're planning to hike. Not all states require hunters or outdoor enthusiasts to wear orange, but some do. A state-by-state list can be found here. For example, in Maine it is state law that any hunter during rifle-hunting season (deer) must wear at least two articles of "solid-colored hunting orange" clothing. Recommended is a vest and hat. Vermont, however, does not have any regulations regarding the wearing of blaze orange, though hunters are strongly encouraged to do so. Having grown up in Maine, I feel naked being in the woods during hunting season without at least a little orange on - and, hey, I haven't been shot yet, so I suppose something is working. I've always been told to avoid wearing white, which can be mistaken for a deer "flag," and I don't mean the Eddie Izzard kind of flag.
Most hunters are aware of hiking areas and try to avoid them. Wearing bells or making lots of noise (which hikers tend to do anyway) also helps, though it does somewhat defeat the purpose of seeking an arboreal interlude. And if you're hiking with a canine companion, an orange vest or collar could save it from being mistaken for a game animal.
Don't let hunting season stop you from enjoying the woods this time of year. There are no mosquitoes or black flies, the summer crowds have evaporated, and the humidity is gone. Until the snow flies, the hiking doesn't get any better, so get some orange and get out there!
