Dr said my dad has had fungus on his hand. He's on a antifungal med. We share the same keyboard/ mouse at work. Will I get this fungus too?

That can happen. Fungi form spores than can contaminate surfaces. Occasional contact with a few spores should not lead to an infection under normal everyday life activities. However, if 2 people share the same items frequently, spores are more likely to be transmitted. After the infection has been treated for a while, maybe after a week of skin anti-fungal cream, transmission is much less likely.
