Is Kissing Dangerous?
According to the Academy of General Dentistry, couples can exchange more than 500 different types of disease-causing germs and viruses in a single kiss.
The most common diseases and viruses that can be transmitted through a single kiss are as follows:
Cold sores are small blisters filled with clear fluid that appear on the lips or around the mouth area. They are caused by the herpes virus and are extremely contagious. There is no cure for a cold sore. Cold sores are highly contagious when they are leaking, but a sore that appears to have a scab can be contagious as well.
It's advisable not to kiss anyone who has a wound on the lip or mouth area because this wound could very well be a cold sore.
It is very easy to catch or transmit the common cold and flu virus by kissing someone when you feel ill or the other person feels ill. These viruses pass from one person to another through saliva and nasal secretions.
"Mono" is commonly referred to as the "kissing disease" because it is easily passed from one person to another by kissing. The disease can also be spread by sharing food, drinking from the same cup or straw, and sharing utensils.
