They are contagious in the sense that other people may start laughing or yawning when they see you doing it, but they are not diseases. I thought that because contagious is derived from the Latin "tangere" - to touch, that both laughing and yawning were infectious. I'm not 100% sure though and would welcome a more knowledgeable answer.
Yawning is associated with tiredness, stress, overwork, lack of stimulation, or boredom. Yawning can also be a powerful non-verbal message with several possible meanings, depending on the circumstances. In humans, yawning has an infectious quality, i.e. seeing a person yawning, or just thinking of yawning, can trigger yawning which is a typical example of positive feedback. Infectious yawning has also been noted in chimpanzees. The primary reason behind yawning is to control brain temperature. It cools off your brain, much like a fan cools off the inside of a computer. The claim that yawning is caused by lack of oxygen has not been substantiated scientifically. Some claim that yawning is not caused by lack of oxygen, for the reason that yawning allegedly reduces oxygen intake compared to normal respiration. Another speculated reason for yawning is nervousness and is also claimed to help increase the state of alertness of a person-paratroopers have been noted to yawn in the moments before they exit the aircraft.
Yes, it is common for people to feel sleepy or have the urge to yawn when they see or hear someone else yawn. This is known as contagious yawning and it happens due to the activation of mirror neurons in the brain, which mimic another person's action, in this case yawning.

When you look at someone while yawning you will probably yawn.Some people think it's contagious.
People smack twice before yawning because when you smack it brings up some of the air you need to yawn.
It's contagious?
if rude and yawning are defined as such i don't see any reason why the act of yawning be rude. yawning is physiologic. would urinating and defecating be rude also?
The spelling of the yawning sound is "yawn."
The cause in not know.
Yawning too much can prove to be fatal. My aunt didn't sleep for a week, kept yawning, and died. You're in trouble
