Well, yes and no. You see someone yawns and yes you do yawn. I've even done this to my pets and they do it too!
On the other hand, we yawn to get more oxygen into the brain so it could be that the room your are in needs more fresh air and that's why everyone in the same room yawns!!

It was long believed you yawned when there was too much carbon dioxide and not enough oxygen in your blood. A part of your brain called the brain stem detected this and triggered the yawn reflex. Your mouth stretched wide and you inhaled deeply, shooting a jolt of oxygen into the lungs and thence to the bloodstream.
