A coworker of mine was recently told that she has mrsa. Her form of mrsa is in her lungs. She claims that her doctor said she could return to work. She would need to be careful when she sneezed, coughed or blew her nose and wash her hands well. She is not wearing a mask. Does this sound like she should have been able to return to work? She works with myself and two other coworkers in close quarters as well as with the public. I am concerned about exposure and the risk of transmission. She is not a hygienic person.
