Is Dasanyang contagious? Is Dasanyang contagious Is the infection rate high?

Good! The question you asked was: "My roommate was diagnosed with Dasanyang, his HBV-DNA test was negative, and his liver function was normal".

1. Da Sanyang indicates that he is infected with hepatitis B virus, if the liver function test is normal, he does not need to do anything, and he coexists peacefully with hepatitis B virus;

2. You first go to the hepatitis B semi-series to confirm whether there is hepatitis B antibody, if there is no antibody, you should follow the standard hepatitis B vaccination method to inject in turn;

3. One month after the end of the whole process of hepatitis B vaccination, test two and a half pairs of hepatitis B to confirm whether hepatitis B antibody is produced, if the antibody is produced, the antibody titer is 10, a hepatitis B vaccine booster shot should be injected, and if the hepatitis B antibody titer is 10, there is no need to inject the hepatitis B vaccine booster shot;

4. The current hepatitis B vaccines are all genetically engineered vaccines, and both domestic and imported vaccines can be used.

Hepatitis B is transmitted in the following ways:

1: Blood and body fluids with hepatitis B virus transfusion. Injection or contamination of broken ** mucosal transmission.

2: Mother-to-child transmission.

3: Sexual transmission.

4: General life contact. Eating together and mosquito bites do not spread.

At present, the most widespread routes of transmission in our country are non-injectable routes, such as mother-to-child transmission and close contact. However, injections that are not sterilized or are not adequately sterilized. Skin test.

Acupuncture. Surgery. ENT examination.

Endoscopy. Communal razor. Ear piercing and other transmissions also account for a significant proportion.

Hepatitis B is highly contagious. DNA negative is rare.

You can test for hepatitis B and if you don't have antibodies, you can get a vaccine to prevent infection.

Living together, they don't share utensils and household items.

Daily contact is not contagious.

It has been known that hepatitis B is very contagious, and according to research, as long as one billionth of a milliliter of blood containing hepatitis B virus is injected into the blood vessels of a healthy person, this person will be infected with hepatitis B virus. Therefore, if the blood products or syringes used during blood transfusion or intravenous injection are not sterilized up to standard, it is easy to cause hepatitis B virus infection. However, in daily life, you cannot be infected by only shaking hands, hugging, kissing, talking with a person with hepatitis B virus, etc.

Moreover, hepatitis B is completely preventable. If you are injected with the hepatitis B vaccine, you will not be able to easily get infected with hepatitis B if you produce antibodies against the virus (anti-hepatitis B virus surface antibodies).

It is recommended to recheck it once.

Hepatitis B is more likely to be negative for viral replication.

The junior ** is likely to transform into liver cirrhosis if it is not timely, so it is necessary to carry out antiviral ** in time, and the efficacy of Lami and Ade in antiviral ** is ideal.

It is contagious, and the infection rate is high.

The positive E antigen is also the third positive indicator that everyone often points out, and the positive E antigen means that the large number of copies of the hepatitis B virus is highly infectious, and the result can be understood as such; For the patients themselves: the rapid progression of the disease will be accelerated, and the rapid development of the disease will lead to a shorter survival period in the human body; The patient is a source of infection, and people who have close contact, share daily necessities, and have sexual contact with the surrounding people are susceptible to the disease, so the chance of infection also increases.

There are generally five routes of HBV transmission:

1. Mother-to-child transmission is the most important mode, and about 30% and 50% of hepatitis B patients in China are caused by mother-to-child transmission.

2. Transmission of body fluids, blood and body fluids formed through close contact in life, such as sharing razors, eyebrow razors, toothbrushes, etc., when living with virus carriers, the mucosa is damaged, and it is also possible to be infected.

3. In addition, hepatitis B virus is transmitted through blood, iatrogenic and sexual.

Everyone knows that liver disease is contagious, so everyone should understand the way of infection in their daily life, so that they can better carry out **. The transmission mode of liver disease Dasanyang is still very worthy of everyone's attention, so what are the transmission modes of liver disease?

1. Blood-borne transmission: If there is no hepatitis B, if there is no hepatitis B, such as blood transfusions, blood or blood products contaminated with hepatitis B, it can lead to infection. The hepatitis B virus is present in the blood of a sick person, so if we have wounds** and inadvertent contact with the blood of a sick person, it is also likely to be contagious, so be careful not to touch the blood and contaminated items of the person with hepatitis B.

2. Mother-to-child transmission: If a pregnant woman has hepatitis B virus, it can be transmitted through the placenta and through the birth canal during delivery. Therefore, for hepatitis B patients, they must pay attention to pre-pregnancy and pregnancy protection.

When you become pregnant while you are getting an immunoglobulin injection, you should also get the hepatitis B vaccine regularly after your baby is born.

3. Iatrogenic transmission: When you seek medical attention, the transmission of hepatitis B can also occur if the temperature of certain medical devices is not properly disinfected or handled improperly after being contaminated with hepatitis B. Usually in some small medical institutions and some informal medical institutions.

In order to prevent hepatitis B infection, it is relatively safe to choose a regular hospital for ** or examination.

4. Sexual contact and communication: For hepatitis B patients and Dasanyang patients, unprotected sex life is also contagious, so hepatitis B patients should pay attention to taking protective measures in sexual life.

5. Intimate communication: This is the most common way of transmission in the family. Hepatitis B patients and carriers, their blood, secretions, etc., contain the hepatitis B virus, and if contaminated with utensils, some are also contagious and transmissible in daily necessities.

？Although both the big three yang and the small three yang are more contagious diseases, many people think that the big three yang must be more contagious than the small three yang in daily life, so what is the big three yang is more contagious? Or is Xiao Sanyang more contagious?

How can you tell? In this regard, we asked the hepatologists of Zhengzhou Zhongda Liver Disease Hospital to introduce it to you. Normally, Xiaosanyang refers to the positive hepatitis B surface antigen, hepatitis B E antibody and hepatitis B core antibody, and the number of hepatitis B in Xiaosanyang patients is relatively small, the replication is weak, and the infectivity is weak; Dasanyang refers to the positive hepatitis B surface antigen, hepatitis B e antigen and hepatitis B core antibody, and the number of hepatitis B virus in the body is relatively large, the replication is relatively active, and the infectivity is strong.

Through the above statement, everyone should say, isn't this that the small Sanyang is not as contagious as the big Sanyang? In fact, the infectivity between them is not judged according to that, but according to the patient's own physical condition and the degree of activity and viral load of hepatitis B virus in the body, if the liver function of the patient is abnormal, the hepatitis B virus in the body is very unstable, and the viral load is relatively large, while the liver function of the patient is normal, the virus in the body is relatively stable, and the viral load is relatively low, the infectivity of the small Sanyang will be stronger than that of the big Sanyang. Because whether it is a small Sanyang or a large Sanyang, there will be extremely unstable situations, so it cannot be determined that the contagiousness of the small Sanyang or the contagiousness of the big Sanyang is large.

Whether it is a small Sanyang or a big Sanyang, it is contagious, so the majority of patients must not take it lightly and should actively accept it, so as not to worsen the condition, not only to cause great harm to themselves, but also to bring threats to others. Through the above detailed introduction, everyone must already know, so remind the majority of patients to have a correct understanding of them, and check some relevant books in their free time to increase their knowledge of liver disease, so as to better prevent it.

Hepatitis B is in the acute infectious period, so it is necessary to pay close attention to it and recheck it regularly as soon as possible. If you are going to have a child, you should pay attention to regular hepatitis B immune globulin injections during pregnancy, and the hepatitis B vaccine should be given within 24 hours of the birth of the child, and the possibility of inheritance is generally very small. In addition, hepatitis B can be transmitted through body fluids, including tears, sweat, breast milk, etc., so it is recommended not to breastfeed.

There is also a chance of infection from bodily fluids. Therefore, it is important to vaccinate the child, and it is better not to breastfeed the child.

Upstairs is the right solution, I hope you and your children can be healthy.

Now the child can be vaccinated just after birth, and it will be fine after the injection.
