Definitely any gold jewelry you have on your person would be beneficial. Technology would probably put you at risk.

I would say that for most people, they would be SOL. Not much chance of surviving. Women would definitely be on the short end of the stick.

Your best bet would probably try to eek out a living out in the wilderness as many suggest. Less chance of being hit by an epidemic going around.

Now then, if you knew this was coming? Obviously some period clothing, gold, antibiotics would be your friend. Wouldn't mind a nice firearm and perhaps a muzzleloader when your cartridges are gone.

Walk softly and carry a big big stick (that spits fire). The man with the biggest stick wins.
