My co-worker has children that currently have pink-eye. Can my he spread this to the rest of us that share a small office? I really do not want pink eye. But I know it is very contagious, and can spread through contact. Can he unknowingly bring it into ou

Pink eye. To avoid transmitting the pink eye, wash hands frequently, avoid contact with those infected or those with sick contacts.
Yes, . Yes, your co-worker can spread "pink-eye", also known as viral conjunctivitis, if he is not careful. He should avoid sharing towels at home, wash his hands after contact with his children, avoid eye rubbing, and avoid sharing eye drops. You can do the same in your office to avoid contracting it yourself.
