My co-worker believes she’ll get sick if someone has a cold or virus, and she talks about getting sick all the time. Can her negative talk actually affect her immune system?

Yes, her negative thoughts can adversely affect her immune system. She is also right in that if she is close to someone who has a cold caused by a virus, she could possibly get the cold because viral colds are very contagious.
