Well, I don't know why yawns are contagious because scientists really don't know what cause yawn's in the first place. However, on a lesser level, I believe yawns are contagious because when you see someone yawn, you tend to think of how tired you are. Therefore, you yawn too. And plus it is pretty amusing when you have a yawn fest with someone and just cannot stop yawning back and forth.\nHope this helps!

no\n\n\nMono is spread through saliva and is often called "the kissing disease". Although it is not highly contagious by casual contact, avoid sharing food, dishes, glasses, or utensils. Regular hand washing should also be practiced. The virus has been shown to be present in saliva for up to one year. Most cases of infectious mono are without symptoms, with resultant permanent immunity.

Spread by virus-infected droplets that are coughed or sneezed into the air, the flu is contagious. People infected with the flu are contagious as long as they show symptoms (most of the time that means about 1 week for adults, but for children it can mean up to 2 weeks).

It's not that they are contagious.  Its just that people yawn because their brain isn't getting enough oxygen and when someone sees another person yawning they....yaaaaaaaawwwwnn.  And then another person sees THEM yawning and they think, "Hey, maybe MY brain needs more O2.  I think I'll just Yaaaaaaaawwwwn.  And then another person sees them yawning and they think, "Oh no, I don't have time to Yaaaaaaaaaawwwnnn."  And then another person sees them yawn and they sa...yaaaaaaaaaawwwwn.  I think this answer is making me sleepy.  Good night.

It is an infection of the tissue around the eye. It is extremely contagious. Passed from person to person. If someone has it their eyes are constantly watering. They wipe their eye, pick up the phone, and its for you hand you the phone. Innocent enough, if some of the germs are brushed onto their hair and then its up against the phone they hand it to you, you place the contaminated phone to your cheek then wipe your eye, get the kleenex cause you most likely will come down with it too. Best prevention against it and so many other things is....wash your hands, once you have it, gotta see a doctor.

It Would Depend, In Large Part, On Whether you had Mono (a Herpesvirus, EBV) Before (and May Have Seen it as Something Else or Never Realized you Were Sick).  I Think she was Contagious Well Before she had Signs, and Not Terribly Long After she had Signs.

Yes. Whenever body fluids make contact with another person' body fluid, there is potential to contract any disease one another is carrying.

My daughter and her 3 children all came down with strep right before Thanksgiving.   The doctor gave them antibiotics, and he gave antibiotics to my daughter's husband and the husband's mother who lives with them, even though they didn't test positive for strep, because he said that they were all exposed and would probably get it.  So, that makes me think that it is highly contagious when you are in direct contact with a person with strep.   Three symptoms of strep, besides a sore throat and swollen glands, are nausea, aches and pains, and a headache.  Since you have all three, you probably have the strep virus and you need to get on some antibiotics.

It is possible that yawns are contagious because at one time in evolutionary history, the yawn served to coordinate the social behavior of a group of animals. When one member of the group yawned to signal an event, all the other members of the group also yawned. Yawns may still be contagious these days because of a leftover response (a "vestigial" response) that is not used anymore. None of this has been proven true and yawns are still one of the mysteries of the mind.\n\nAlso,\n\nThe reason yawns are contagious? Power of suggestion perhaps. If you're out late with your friends after school, you're probably tired. You're probably on the verge of a yawn, too, and seeing one person do it is enough to drive everyone to yawns.

Not contagious but we are affected by an others yawning. This is called "Alolomimea" funny name but its what its called. Scientists believe that the reason we react to other people yawning is because in our early history ("caveman times") we needed to regulate our sleeping patterns so we could all survive together. Kinda like one for all and all for one deal. So if one of our cavemen buddies was tired we would all need to rest so we could all effectively hunt as a unit. It served  us as a natural "hey dude im tired lets take a break so we can hunt better and not die" It's a true story!

The good news:\n\n1. The cold is most contagious for about first three days of your symptoms.  \n\n2. Saliva is not an efficient means of spread of most cold viruses. Symptomatic people with colds have no detectable virus in their saliva in 90 percent of cases and kissing is not likely to transmit the common cold.\n\nThe not so good news.\n\nHand-to-hand direct contact plays an important role in disease transmission, so if you are contagious just touching another person maybe enough to transmit it.  \n\nThe bottom line, if you still have the cold symptoms, you may pass it to your partner just by being with them.  Kissing will make little difference. Hope that helps.

So far bird flu is not contagious from human to human.  So unless someone brings home a flock of chickens, I don't think you have much to worry about.

Well, I guess it depends on what kind of illness.  Is it contagious?  Otherwise, most people will be sympathetic to someone who is sick.
