The 'Kissing Disease' Lives Up To Its Name

Ready for your New Year's kiss tonight? Just make sure he hasn't had mono in the last five months.

Just before the biggest kissing night of the year, a new study finds some not-so sexy news: Smooching really does spread mononucleosis.

While, mono has been labeled as 'the kissing disease' for sometime now, new research published in the Journal of Infectious Diseases proves deep kissing is actually the only factor that increases the risk for catching mono.

Other factors, such as diet and amount of exercise and stress, did not increase the students' risk, according to Medical Daily.

Symptoms for the viral disease include sore throat, fatigue, headache, fever decreased appetite and swollen tonsils — though not everyone has symptoms.

The study followed 546 college students from freshman to senior year, and during this time, doctors diagnosed 66 of the students with mono, but only 59 showed symptoms.

While students with mono were sick for an average of 17 days, they were capable of spreading the virus for as long as 5 months.

While we encourage you to pucker up when the ball drops (after all, kissing can save marriages), just make sure it's with someone who hasn't had the illness in the last five months.
