Are sinus infections contagious through kissing?

"Unless you have a bad cough, and some of the respiratory mucus has made its way into your saliva, the cold virus will not be transmitted by kissing." Most of us think colds are highly contagious. This is because the mucus from the respiratory tract of someone infected has to get directly into your respiratory tract.

Likewise, can a sinus infection spread from person to person?
