Pucker up! Have you ever heard of the "kissing disease"? If you said that it's mono, you're absolutely correct.


How Do Kids Get Mono?


You probably know what your lymph nodes are, and you probably guessed that your salivary glands are inside of your mouth. But what about your spleen? It's located on the left side of your abdomen, just under the ribcage, and it helps cleanse your blood of bacteria and viruses.

Mono is contagious, which means you can spread the virus to other people who haven't had mono before. Even though you can get mono from kissing someone infected with EBV, there are other ways you can get it, but they all involve contact with saliva. Sharing straws, toothbrushes, or food from the same plate can also spread mono.

At first, people usually don't feel sick after getting infected with the EBV virus. So someone could be infected — and be spreading mono — and not even know it. That's why it's important not to share things like forks, straws, water bottles, or lip gloss at school.

What Are the Signs of Mono?


  • fever
  • sore throat
  • headaches
  • sore muscles
  • enlarged liver or spleen


What If I Have Mono?

Usually with mono you will need plenty of rest. This might mean no school for a while, no sports, and no running outside playing with friends or even wrestling with your little brother. While you're resting, it's a good idea to drink plenty of water and other fluids. You can ask your mom or dad to give you a pain reliever if you have a fever or if your muscles are sore. Don't take any aspirin, though, because that can put you at risk for a condition called Reye syndrome, which can be dangerous.

Other kids might not feel very sick at all, so a lot of bed rest isn't necessarily for everyone. But it's very important to listen to your body. Someone who has mono should tell a parent if he or she starts feeling worse. And if the person feels tired and run down, it's the body's way of saying more rest is needed.

If you play contact sports, such as football and basketball, you will probably need to avoid them while you're sick and for about a month after the illness — especially if your spleen is enlarged. Your doctor will let you know when it's safe for you to get back in the game.

You'll probably be happy to hear that mono usually goes away after a few weeks, even though you'll have to take it easy for awhile. Make sure you wash your hands after you cough or sneeze. Keep your straws, forks, and toothbrushes to yourself, and . . . no kissing for a few months!
