Guest guest Posted February 23, 2011 Report Share Posted February 23, 2011 How Infectious is a Kiss? It's been said that when you kiss someone, you kiss everyone that person has kissed before. I'll leave the doctors to debate the truth of that claim, but a point worth keeping is that sometimes kissing can be very intimate and, unfortunately, an opportunity to spread infection. Is viral hepatitis one of those infections? The Easy Answer In order to be exposed to viral hepatitis, the person you're kissing would need to actually have viral hepatitis. In other words, you can't catch what isn't there. Also, the viruses that cause hepatitis are basically spread through blood and bodily fluids (hepatitis B, hepatitis C, hepatitis D) and fecal-oral contact (hepatitis A, hepatitis E). The chance of contracting hepatitis from kissing is therefore small. Quick Review of Hepatitis Viruses Hepatitis A Virus Hepatitis B Virus Hepatitis C Virus Hepatitis D Virus Hepatitis E Virus The Not-So-Easy Answer Since it's also been said that nothing in life is easy, maybe this question isn't as simple as we'd like it to be. The complexity comes from what is theoretically possible versus what is realistically probable. Realistically you're not going to get viral hepatitis from kissing. However it is theoretically possible. Since any type of direct contact with infected blood is a possible way to spread some of these viruses, there are kissing scenarios where the risk of exposure increases. I'll let your imagination wonder, but think about cold sores, cuts and prolonged kissing. The Bottom Line It all comes down to the level of risk you're willing to accept. Most of us regularly accept health risks of all kinds and levels in our lives. For example, we may drive a car, play contact sports, or smoke cigarettes. Obviously most types of kissing are completely harmless and won't allow any opportunity to spread the hepatitis viruses. For most people, the rare kissing scenarios that may allow some theoretical exposure to one of the hepatitis viruses will be risks worth taking. http://hepatitis.about.com/od/lifestyle/a/Kissing.htm Quote Link to comment Share on other sites More sharing options...
