Kissing is considered a common way of expressing love, but have you ever wondered whether kissing on the lips can also cause some diseases? Actually, in kissing there is not only exchange of emotions but also exchange of saliva. Some bacteria and viruses in this saliva can be transmitted from one person to another. Although not every kiss is harmless, certain situations may increase the risk of spreading infection.
What problems can arise while kissing?
According to the health information website *Hawaii Family Dental*, saliva is exchanged between two people during a deep or French kiss. Saliva contains water, enzymes, electrolytes, and proteins, as well as a variety of bacteria and viruses. A study published in the journal *Microbiome* shows that a kiss can transfer approximately 80 million bacteria from one person to another. Most of these bacteria are harmless, but if a person has a weak immune system, some bacteria can cause infection.
Which diseases spread most easily?
Experts say that the virus that causes the common cold first spreads from one person to another through kissing. If your partner has cold then the risk of infection increases. In addition, mononucleosis – often known as the “kissing disease” – is caused by the Epstein-Barr virus and can also be spread through saliva. Symptoms of this disease may include fatigue, fever, and swollen lymph nodes in the neck.
risk of other diseases
Herpes simplex virus-1 (HSV-1) can also be spread through kissing. Specifically, the virus spreads through saliva, even if no lesions are visible around the mouth. In addition, if a person has the flu, there is a risk of transmission of influenza viruses through respiratory droplets during kissing. Some bacteria associated with gum disease can also spread from person to person through saliva, increasing the risk of future oral health problems.
When is the risk higher?
Some conditions increase the risk of infection. The chance of infection increases if your immune system is weak, your partner already has an infection, you have cuts or sores in your mouth, or you have poor oral hygiene. However, kissing also has its benefits.
How can you stay safe?
To reduce the risk of infection, prioritize good oral hygiene. Brush regularly, use dental floss, and have periodic dental checkups. Avoid kissing until you or your partner has completely recovered from an illness. In case of cold and cough, close contact should also be avoided.
