Can Black mold affect someone even if they aren't in the same room?

I have a friend who just moved into a new place a recently noticed black mold in his room. He's been staying in his living room to try to avoid it, but he's been coughing up mucus that is yellow/green and thick, he said he thinks he has coughed up blood, he had a headache and stuffy/runny nose, etc. At first, I thought he had a cold until I looked up the symptoms of mold toxicity. I'm trying to get him to schedule an appointment to see a doc tomorrow, but he is being stubborn and doesn't want to go. He said he has to go to work, but I'm worried about him.
