kissing increases risk of meningitis in teenagers

Kissing may not only lead to an STD, but also to meningitis. I doubt this news will stop teens from kissing.
Making the news today are the results of a research project funded by Meningitis Research Foundation which looked at why teenagers and young adults are the second most at risk group of contracting meningitis and septicaemia - the blood poisoning form of the disease.

One of the conclusions of the study, lead by Professor Robert Booy, co-director of the National Centre for Immunisation Research at the Sydney Children's Hospital, was that intimate kissing might be partly responsible for increased risk.
