There are over 3000 documented species of spiders in North America. The vast majority of these are not dangerous. Most of them have fangs that are not strong enough or are too small to pierce human skin. If they manage to bite, they leave behind red wounds that are itchy and heal in about a week.
Spiders with fangs strong enough to puncture human skin and inject toxic venom can cause major health problems.
