Is it good to go to work, exercise, or play sports, if you have the flu?

I'm wondering if it's better to rest and not spread it around. However, I see professional athletes on TV, who are sick with the flu, still playing the game. Why don't they just sit out? Should people be inspired by them to tough it out, go to work, and still exercise, even though they're sick?
