Information From A To Z Hepatitis B

Hepatitis B is a "silent killer". damaging liver function, causing liver failure, cirrhosis and even liver cancer. In Vietnam, the rate of hepatitis B virus infection accounts for 10 - 15% of the population. However, many people infected with hepatitis B still do not fully understand the dangers of the disease and its effective preventive measures.
What is hepatitis B?
Hepatitis B is an infectious disease caused by the hepatitis B virus (HBV)

. If not promptly detected and treated, the disease can become chronic, which can cause liver infection or even liver cancer.
Hepatitis B is divided into two types: acute hepatitis B and chronic hepatitis B.
Acute hepatitis B
Acute hepatitis B arises in the first 6 months after a person becomes infected with the virus, which is an early stage of the hepatitis B infection process About 90% of people infected with acute hepatitis B virus will recover on their own and 10% of people will The infection progresses to chronic hepatitis B, which is dangerous to the liver.




Whether or not a person with acute hepatitis B becomes chronic depends on the age of the person who is infected.

Chronic hepatitis B
Chronic hepatitis B is when a person has been infected with the hepatitis B virus for more than 6 months after being infected with the virus. This is a dangerous stage of the disease, leading to many unpredictable complications. Chronic hepatitis B has 3 forms:
Hepatitis B infection in healthy people carries the germ
In this case, although the hepatitis B test result after 6 months of infection is still positive, the HBeAg and HBV - DNA indexes are negative, and the liver enzymes at the normal limit, means hepatitis B is not working.
But the patient is absolutely not subjective and should have periodic health examinations because the virus can be activated, reactivated at any time, can even lead to dangerous complications such as liver cancer.
Hepatitis B infection is dormant
In the same way that hepatitis B infection in a healthy person carries the germ, the hepatitis B virus in dormant form is dormant. People living with the disease live peacefully with the virus, still living, studying, and working normally
Active chronic hepatitis B infection (chronic hepatitis B)
Unlike the chronic dormant hepatitis B, the hepatitis B virus can act continuously proliferate, proliferate, causing damage to the liver such as cirrhosis, liver failure, liver cancer
Symptoms of hepatitis B
Depending on whether the hepatitis B virus is active or dormant, the infected person may or may not show symptoms without testing.



People who are chronically active with hepatitis B virus may have the following symptoms:
One of the symptoms of hepatitis B is joint pain
A rash
Athritis
Tired
Jaundice
The stool is gray-green
Dark urine
Itchy
Anorexia
Nausea
Fever
Stomachache
Blood vessels that pop up in the skin like arachnids (also called star veins)
Causes of hepatitis B
Hepatitis B is caused by the HBV virus (Hepatitis B Virus). This virus is spherical, its surrounding shell contains surface antigen HBsAg.
Can hepatitis B be taken?
Hepatitis B is a contagious disease. Its spread mechanism is similar to the HIV virus. There are 3 ways to spread the disease as follows:
Spread through blood
The HBV virus can live in dry blood for days. Therefore, the following actions are easy to spread the virus from one person to another.
Sharing needles, toothbrushes, razors, toenails, nails ..



.
Keep the open wound in contact with the blood of an infected person.
Spread from mother to child
If a pregnant woman is infected with hepatitis B, the fetus is also likely to be infected if there is no timely prevention. The infection rate will increase with each stage of fetal development.
Specifically, in the first 3 months, the infection rate is 1%. In 3 months between the rate is 10%. And if a mother is infected with hepatitis B in the last 3 months of pregnancy, the rate of infection to the baby will be 60-70%.
Therefore, before preparing to become pregnant and during pregnancy, a woman infected with hepatitis B needs to see a doctor, state her medical history so that the doctor can give the most helpful advice as well as measures to take.



timely intervention, ensuring safety for both mother and baby.
Sexually transmitted
Unsafe sex can be the way to spread hepatitis B virus from one person to another. The HBV virus lives in sex products and can be spread through small scratches during unprotected sex.
Therefore, when having sex, it is necessary to ensure that measures are taken to prevent the spread of infections such as condoms, not to use hygiene aids, etc.
Unsafe sex is the way to get hepatitis B
People at risk of hepatitis B
Based on the routes of transmission of hepatitis B, it is possible to identify the most vulnerable groups:
Target group 1:
People infected with hepatitis B through blood, sharing needles and syringes with infected people, often drug addicts, people often tattoo, piercing, manicure, pedicure in facilities Do not sterilize specialized tools carefully and cleanly.
Doctors, health workers are infected when there is an open wound.
