Some people over react yes Mrsa is a very serious infection to the person that has it. I have been a nurse for 15 years, I was also a caregiver to my father that has it. The only way to contract the infection is blood to blood contact and that means air can not touch it . If someone has a scratch and you go to clean out the wound, I would wear gloves, but there is no way you good get the illness unless you had an open cut and rubbed it right on his open cut, with out air touching it pretty hard ha. Yeah. You can get it sharing needles. If the person has pneumonia or a bad cough I would wear a mask for protection. I studied up on this hard when my best friend and my father had it. I took care of both of them completely and never have a got it. So be careful but don't worry to much
I work in the medical field in a nursing home. It depends on the amount of interaction that takes place. But usually you will carry the virus but it will remain dormant and not infect anyone else.
Any scratch they get, open wound of ANY kind will put you at risk. It's very serious and should not be taken lightly.
