Dewberry vines can cause infections too (see sporotrichosis) treat the wound like you would any other and infections are rare.
Don't handle snakes at all of you don't have to, but there is no need to fear them. They are stunningly slow. Even the fastest species move at a light jog for a human. If you are more than 2/3 of the snakes body length away they pose no immediate threat to you. They can strike in the blink of an eye but can't reach forward more than 2/3 their body length.
Excessive fear of nonvenomous snakes is irrational and therefore classified as phobic. Venomous snakes can cause harm and healthy fear of them is warranted.
However, if you are in their environment, I would argue it is your responsibility to avoid them and leave them be. If they are around your house, it is best to call professional removal services if you can and make sure you minimize the areas their prey can shelter or feed around your house, but I won't fault anyone for eliminating a venomous snake from around their house especially if they have small pets or children.
