Should You Be Worried Before Kissing Someone?
It’s been said that when you kiss someone, you kiss everyone that person has kissed before. I’ll leave it to doctors to debate the truth of that claim, but a point worth noting 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
The chance of contracting hepatitis from kissing is virtually non-existent, as hepatitis B, C and D can only be spread through blood and bodily fluids (including semen and vaginal secretions). Hepatitis A and E also don’t spread through kissing, as they are only transmitted through fecal-oral contact.
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 About Hepatitis From Kissing
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, eat fast food, 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.
A Closer Look at Hepatitis Transmission
Here’s a more detailed look at how different types of hepatitis are transmitted:1
- Hepatitis A is transmitted by contaminated food and water and is thus fecal-oral.
- Hepatitis B is transmitted by blood, needles, and sex. Hepatitis B can also be passed along during delivery from a mother to her newborn.
- Hepatitis C is transmitted by needles and blood.
- Hepatitis D can only be transmitted to a person who already has hepatitis B. Hepatitis D is transmitted by blood, needles, and sex. Hepatitis D can also be transmitted during delivery from a mother to her newborn.
- Hepatitis E is transmitted by means of contaminated water. Like hepatitis A, hepatitis E is fecal-oral.
