Blood on stethoscope

I am rotating through my peds rotation, and truly love it. But one thing worries me. I think I am probably too paranoid. When pediatricians attend newborns in the OR or birthing suit, there is often a lot of blood/body fluid on the baby, which can go everyone despite the best effort to clean the baby thoroughly with towels. And the blood often gets on the stethoscope as well. Were pediatricians ever worried that the blood can touch the earpiece of the stethoscope and get into their ears?
