I've had mrsa 6 months ago, i haven't have an outbreak since, is it safe to get a tattoo?

Likely okay: If you have had recurrent outbreaks I would still meet with your primary care doctor, but if just a MRSA boil or something likely not at much increased risk. Just make sure to carefully follow the care instructions following getting the tattoo.

The germ tends to: stick. On the other hand, tattoo infection rate is pretty low. Hard to find exact numbers in the literature. If you send a direct in-box question I know several tattoo artists who can give direct estimates. On the other hand, your likelihood of still having MRSA is certainly over 50%, and your risk of skin infection is higher than average (only 10% of people have germs on them that can infect).
