Not hepatitis A or C either. EWH
thanks doctor.i see you mention hepatitis B, but what about hep C or A??
am i in the clear??
The two exosures you describe are no risk. AS far as the shared toothbrush is concerned, there is no STD, including hepatitis B and HIV which would survive on a toothbrush between uses as you have described. Any residual toothpaste (it never all gets washed off) would kill the viruses and bacteria, as would rinsing and drying. No worry at all.
As far a piercing is concerned. Also no risk. Many people like the sensation of the studs. After her piercing the hole in the tongue healed and was no more infectious than anyone else's tongue.
No testing needed. EWH
