Is It Possible to Transmit Hepatitis Through Saliva?

Hepatitis B virus is a DNA virus belonging to the hepadnavividae family. According to current knowledge, HBV is only susceptible to humans and orangutans, causing viral hepatitis B disease. The intact hepatitis B virus is granulated and is also called Dane.

Hepatitis B virus transmission

Hepatitis B virus is a

After the virus enters the liver cells, the capsids are removed, and the DNA enters the nucleus of the liver cells.

The positive-strand DNA is repaired to a complete state by using the negative strand as a template under the action of DNA polymerase.

Double-stranded DNA forms a closed-loop supercoil. Under the catalysis of cellular RNA polymerase, short-stranded DNA is transcribed into different lengths of RNA. Short RNA acts only as messenger RNA, and long RNA is also pregenomic RNA.

Mother-to-child transmission

Whether or not the hepatitis B virus-infected person will be infected with HBv, medical research has found that the following behaviors cannot cause transmission of HBv:

(1) Eating together. The digestive tract is not suitable for the survival of HBv. There are substances that inhibit HBv in the digestive system, which can be destroyed in the intestine. Experiments were not successful in giving orangutans to foods containing HBv; injecting HBV directly into the stomach and intestines did not make them infected.

(2) Shake hands with each other. Although HBv markers may be detected in the sweat of people with hepatitis B virus, the handshake is still safe. It s not that germs and viruses fall into your hands, and the human body has its own disease resistance. Sweat also contains an acid, which is not conducive to the growth of germs and viruses. If you pay attention to washing your hands, it won't be a problem.

(3) Ritual kissing . HBv may be contained in the saliva of people with HBV infection, but ritual kissing is not contaminated with saliva.

(4) Hug each other. This is a common etiquette behavior, because without substantial contact, transmission of HBv is not possible.

(5) Dancing. There may be hand in hand movements when dancing together, which are not enough to constitute the spread of HBv.

(6) Common games and travel. Mealing in the wild, intermingling with each other, talking and laughing can not cause the transmission of HBv, because the virus in the hepatitis B virus carrier does not have a transmission channel with the other party, just general contact, how can HBv get into the other's blood. The environment in nature is by no means a place to spread HBv.

(7) Living in the same room. The students are in a collective dormitory, and there are those who are infected with hepatitis B, and they will not spread to each other. HBv cannot survive and replicate in the air. Each germ and virus has its own unique transmission channel. HBv is mainly transmitted through the blood channel and will not invade the human body from the respiratory tract. Even if the other party sneezes or coughs, it cannot constitute an infection.

(8) Classes or work at the same unit. It is also very safe and does not spread hepatitis B.

When the healthy side suffers from oral ulcer diseases, due to the rupture of the oral mucosa, the saliva exchange behavior with hepatitis B patients at this time will cause the hepatitis B virus to infect through the saliva, and the healthy side will be infected with hepatitis B. Although the probability of such transmission is extremely low, the possibility of being infected with hepatitis B has to be paid attention to.
