The virus that causes
mono (Epstein-Barr virus) isn't spread as
easily as most people think. If you follow these tips, you can reduce the
chance of spreading or catching mono.
Don't kiss or share dishes or eating utensils
with someone who has mono. (A brief kiss on the lips is not likely to spread
Epstein-Barr virus. It is spread when saliva from an infected person gets into
another person's mouth.)
Don't donate blood if you have mono.
Although it is unusual for the Epstein-Barr virus to be spread through blood,
it is possible.
