i think you will be okay. it's not like you actually had their blood on your hands and i've never heard of blood dried on paper harming anyone. take a deep breath you are going to be okay.
dried blood. i was handling some paperwork noticed a red blotch on the paper work the paperwork would have been touched by another person a few hours before i do not believe i had any cuts on my hand i am extremely ocd and over wash my hands to the point they become red at times. i did use hand sanitizer after coming in contact i do not remember if that piece of paperwork glanced my mouth in handling i squeezed sanitizer on the neck of my shirt and whipped my mouth off is there any risk in catching anything?
