Hepatitis can be contagious!Which transmission channels need to be guarded?

July 28 is World Hepatitis Day.

The theme of this year is "preventing hepatitis and healthy you and me". It aims to call on the public to actively take the initiative to vaccinate hepatitis, actively conduct physical examinations to understand the health of the liver. Patients with chronic viral hepatitis receive standardized antiviral therapy, comprehensively curb viral hepatitis to human health to human health to human health. Threat.

The liver is the largest substantial organs of the human body and the largest digestive organs in the digestive system.

It seems to be "hard core", but it is actually fragile, especially in front of the virus. As of now, there are 5 types of liver infection viruses with clear clinical studies, all of which can directly lead to severe liver disease.

1. What is hepatitis?

Hepatitis is a collective term for liver inflammation. Hepatitis is divided into two categories, namely viral hepatitis and non -viral hepatitis (autoimmune, alcoholic, metabolic, pharmaceutic hepatitis, etc.). Most of the hepatitis in our lives refers to the viral hepatitis caused by the type A, B, C, D -type, and Wu type (five brothers) hepatitis virus. It is contagious, but the transmission pathway is different.

In our country, the second child B and the third child C are the most common, and it is often easy to develop into liver cirrhosis and liver cancer due to the delay of the disease. Ding liver virus is often accompanied by hepatitis B virus. Hepatitis A and Hepatitis A are mostly acute onset, and the prognosis is good.

Hepatitis B virus has no medicine to cure, but there are mature vaccines to prevent it. The second hepatitis B vaccine has entered the door for many years, and the second brother cleaned up. The third hepatitis C virus is still in a bachelor. There is no vaccine to prevent it, but there are already medicines to cure.

The fourth Ladin liver virus cannot survive independently due to the problems brought out of the mother's tire. Only with the second brother B virus can barely maintain this life. Therefore, as long as the second child's hepatitis B virus is properly controlled, the fourth Ladyin hepativirus can also be stifled in the cradle.

Which transmission channels need to be guarded?

Different hepatitis viruses are slightly different.

The most common form of hepatitis A and pental hepatitis A and Koba is dung -oral communication. A close life with the infected person can also be infected, which means that eating together is risk of infection with hepatitis A and pental hepatitis. In addition, crustaceans living in water are likely to be contaminated by hepatitis A virus. When people eat unsustering oysters, clams, oysters and other aquatic products, there is a high risk of hepatitis A virus. The main population of hepatitis A infection is children and adolescents, and winter and spring are the peak period of hepatitis A.

The spread of hepatitis B and hepatitis C mainly includes blood, maternal and infant transmission, and sexual transmission. Among them, the path of maternal and infant transmission is the most important way to spread hepatitis B infection. Adults are basically not infected with hepatitis B virus. Even infected with hepatitis B virus, most of them are acute type B virus hepatitis. Acute type B virus hepatitis is mostly healed within 6 months. In terms of sexual transmission, there is a protective sexual contact with patients infected with hepatitis B virus. The damaged skin and mucosa can spread hepatitis B virus.

T -type hepatitis virus and hepatitis B virus have the same pathway, that is, transmission through blood, sexual contact, and maternal and baby transmission. However, the dito hepatitis virus is rarely infected alone, and it is mostly infected with DNA virus such as hepatitis B virus.

In addition to the above mentioned hepatitis, in the past, water type is most common, with seasonality, more common in the rainy season or flood, and more common in people with unclean food history. The people are mainly young adults. Pregnant women are prone to high sensitivity, prone to severe pental liver, and high mortality.

How to prevent it?

Some friends asked, how can I prevent meals when I often dine outside?

1. Vaccine. Vaccination is the most effective measure to prevent hepatitis B. It is recommended that you can go to the regular hospital for "five hepatitis B" and liver function testing. Under the guidance of a doctor, you can go to the community vaccine vaccination department if necessary under the guidance of a doctor. Inoculation of hepatitis A and pental hepatitis A can effectively prevent hepatitis A and pental hepatitis A.

At present, hepatitis A vaccine and hepatitis B vaccine have been incorporated into the immunization planning vaccine in my country, and the government will provide you with free vaccination. At present, the vaccination process of hepatitis A vaccine in Jiangsu Province is the first needle -liver vaccine for the first 18 months, and then indirectly seed the second needle in 24 to 30 months. The interval between two needle -n -nail in vaccination is not as short as 6 months. The routine immunization procedure of hepatitis B vaccine in our province is "0, January, June", with a total of 3 stitches. Hepatitis B vaccine should be vaccinated as soon as possible within 24 hours of newborns.

The world's first pental vaccine was developed by my country and has been listed. The vaccination object is over 16 years old, and the vaccination process is 0, January, and June. It is recommended that high -incidence of hepatitis (such as people in contact with pigs, pre -pregnant women, middle -aged and elderly groups, etc.) can be used to prevent vaccination of pentalitis vaccines to improve immunity.

2. Cut off the transmission path

There are currently no hepatitis C vaccines, but effective measures can be taken to cut the transmission path. Hepatitis C can prevent:

Reject drugs, do not share needle injection of drugs;

Go to a regular medical and health institution for injection and blood transfusion;

Do not share tattoos, puncture and other tools with others;

Do not share shaving knives, toothbrushes, etc. that may cause bleeding with others;

The correct use of condoms to avoid unsafe behavior, which can greatly reduce the risk of hepatitis C virus.

3. Develop good hygiene habits

Hepatitis A and pental hepatitis A are mainly transmitted through manic-oral, and water sources or foods are contaminated can cause outbreaks. Develop good personal hygiene habits, wash your hands before meals, do not eat raw food, and do not drink raw water to prevent "disease from entering the mouth".

special reminder

It should be emphasized that there is no daily contact with blood exposure, such as working with patients with hepatitis B/C, shaking hands, hugging, living in a room, and even dining and sharing toilets. Theoretically, it will not be infected.However, if you are close contact such as marriage, it is recommended to test the hepatitis virus before marriage.If you are positive, you need to treat it as soon as possible, for yourself, for your lover, and for the health of the next generation.
