Can u infect ur partner with the Hepatitis B virus by just kissing?

Hepatitis B virus (HBV) is similar to the viruses that cause the common cold. However, unlike cold viruses that infect the cells of your nose and throat, HBV infects the cells of your liver. Although the virus lives in the liver cells, it is not the virus itself that causes harm to your liver. It is your own immune system, in its effort to destroy HBV, that injures your liver.

As the hepatitis B virus reproduces itself with in the cells of your liver, HBV particles are released into your blood and your blood becomes infectious. Just one teaspoon of your blood can have up to one trillion particles of HBV! This is why it is so easy to pass HBV infection to others who come in contact with your blood.

HBV, however, is not the only virus that can infect a person for life and cause long-term infection. Chickenpox, for example, remains in the body after the childhood illness occurs and can reappear in later life as shingles.

How did I get infected with hepatitis B?
In populations around the world with moderate or high rates of HBV infection (for example, Asians, Pacific Islanders, Africans, Eastern Europeans, Russians, Alaskan Natives, Canadian or Greenland Eskimos), transmission occurs almost entirely during early childhood. In these populations, the most common way HBV is spread is from mother to baby during birth.

If you are chronically infected with HBV and were born in a country with a moderate or high rate of HBV infection (as noted above), chances are your mother was infected with HBV and you came in contact with her infected blood as you passed through the birth canal. HBV infection may also be passed from mother to baby during the early weeks of life or at any time during childhood. It can also be passed to children from other infected family members or siblings.

There are many other ways people can get infected, too. About one-third of people with HBV do not know how they got the infection, and many of them never will.

Can other people get hepatitis B infection from me?
Yes. HBV is found in your blood, semen, vaginal secretions, and to a lesser extent in saliva, tears, and sweat. Some of the ways that HBV can be passed from you to other people include:

* contact with your blood through open wounds, cuts, or scrapes.
* sharing personal care items such as toothbrushes, razors, nail clippers, hair scissors, or washcloths. (Any of these items might be contaminated with small amounts of blood.)
* sharing instruments for tattooing, ear piercing, or body piercing.
* a needle stick or sharing needles for drugs like heroin.
* sexual contact (vaginal, anal, and oral).
* during childbirth. Source(s): http://www.immunize.org/catg.d/4118.htm...

The simple answer is yes you can spread Hepatitis B by kissing.

"How is hepatitis B spread (transmitted)?

Hepatitis B virus is spread or acquired through exposure to infected blood or the body's secretions. The highest concentrations of hepatitis B virus are found in the blood, semen, vaginal discharge, breast milk, and saliva. There are only low concentrations of hepatitis B virus in the urine and none in the feces. Therefore, hepatitis B is not spread through food or water or by casual contact. Furthermore, hepatitis B virus is no longer transmitted by blood transfusions because all blood for transfusion is screened (tested) to exclude contamination with hepatitis B virus."
