Today (July 28, 2021) is the 11th “World Hepatitis Day” in the world.
July 28th is the birthday of the late Nobel Prize winner of Baruk Bloomberg. To commemorate the hepatitis B virus discoverer, the WHO decided in May 2010 as “World Hepatitis Day “The purpose is to raise people’s understanding of viral hepatitis.
The WHO called on all countries to work together to eliminate the public health threat of viral hepatitis by 2030. The theme of the World Hepatitis Day this year is “eliminating hepatitis and not to be waiting”, which conveys the urgency that must work hard to eliminate the public health threat of hepatitis by 2030.
In the world, one person dies every 30 seconds to hepatitis
Globally, one person died of hepatitis -related diseases every 30 seconds, even in the current new crown pneumonia crisis. Viral hepatitis is one of the main causes of global disease burdens and an important public health challenge facing my country. There are five types of hepatitis viruses, namely type A, B (HBV), C (HCV), T -type and pentagonal types.
The latest data from the World Health Organization in 2020 estimates that 325 million people around the world suffer from type B and C viral hepatitis. Death caused by 900,000 hepatitis B virus infections every year. Anti -virus drugs can cure more than 95%of hepatitis C infection. Hepatitis B and C is the most common cause of death. There are 1.1 million people lost their lives every year, which leads to 1.1 million deaths and 3 million new stains per year.
In China, chronic viral hepatitis causes about 380,000 people each year, mainly because hepatitis and liver cancer are mainly caused by hepatitis. In the context of 2019 coronary virus disease, viral hepatitis still takes thousands of people every day.
In December 2019, the Lancet Gastroenterology & Hepatology of the Lancet GastroEnterology was published online. The report deeply reviewed the epidemiology and etiology of 11 countries and regions in Asia Pacific, and systematically discussed the burden on liver disease in various countries and regions.
The Asia -Pacific region has more than half of the world’s population. According to WHO’s global illness burden report in 2015, 62.6%of the number of deaths in the world’s liver disease came from the Asia -Pacific region (1,312,480/2,095,207). Among them, the burden and main causes of liver disease in different countries are different. In Asian countries, the median percentage of the number of people who died in liver disease accounted for 3.9%.
In 2015, the acute viral hepatitis -related death (N = 108,276) accounted for 8.2%of the total number of deaths related to liver disease in the Asia -Pacific region. The main causes of causes of acute viral hepatitis are acute hepatitis B (59.6%) and acute pentalitis (32.1%), while acute hepatitis A accounted for only 6.3%.
China is currently the country with the largest number of hepatitis B (HBV) infection in the world. It is estimated that there are about 70 million chronic HBV infected people in my country, of which about 20 million-30 million patients with chronic hepatitis B patients are. However, through the mandatory screening of HBV/HCV of the general vaccination plan and blood products of neonatal, the popularity of hepatitis B surface antigen (HBSAG) in my country has declined.
According to a systematic review in 2015, the HBSAG popularity rate in mainland China decreased from 14.0%from 1957-89 to 5.4%from 1990-2013. At present, the popularity of HBSAG in my country is 5%-6%.
How to prevent hepatitis?
Hepatitis caused by different viruses is different from the clinical process after infection. Hepatitis A and pental hepatitis A are the diseased disease, which can be transmitted through polluting hands, food or water; hepatitis B, hepatitis C, and Ding liver are mainly transmitted through maternal and infants, sex, and blood transfusion. In mainland China, the main ways of HCV infection include infusion of contaminated blood products, invasive medical measures, and injection drugs. Since the self -compulsory HCV screening of blood products, blood transfusion infections have been significantly reduced (in Beijing, the new infection ratio caused by blood transfusion before 1992 was 84.2%, and 14.3%after 2004). Early treatment of viral hepatitis should be found, early diagnosis, early isolation, early report, early treatment.
Inoculation of hepatitis B vaccine is the safest and effective measure to prevent hepatitis B. Hepatitis B maternal and infant blocking measures can effectively prevent the spread of hepatitis B mother and baby. my country is carried out for free hepatitis B vaccine for newborns. The entire process of immunization needs to be vaccinated with 3 stitches “0, 19” immune procedures. Among them, the first needle should be vaccinated as soon as possible within 24 hours after birth. Newborns born to the hepatitis B virus surface antigen -positive pregnant woman should be vaccinated as soon as possible within 24 hours after birth. At the same time, the hepatitis B immunoglobulin is injected, and the subsequent inoculation is completed in accordance with the hepatitis B vaccine immunogenesis.
In addition to newborns, adult high -risk people such as medical staff, often contacting blood and blood products, staff members of childcare institutions, those who often accept blood transfusion and blood products, low immune function, those who are prone to trauma, hepatitis B virus surface antigen Family members of the positive person, male homosexual actor, multiple personality companions, or injection drugs should also be vaccinated. In terms of treatment, hepatitis B is easily chronic. At present, no effective drugs can completely remove hepatitis B virus. Improve the quality of life and extend life. Patients should establish confidence, maintain patience, follow the doctor’s order, actively cooperate with treatment, and adhere to regular examination to ensure the treatment effect.
Hepatitis A, Hepatitis
Pay attention to diet, water hygiene and vaccination, can effectively prevent hepatitis A and pental hepatitis A.
Do a good job of environmental hygiene, strengthen water sources and feces management, and improve water supply conditions; develop good personal hygiene habits, wash your hands before meals, do not eat raw food, and do not drink raw water.
Vaccination can effectively prevent hepatitis A and pental hepatitis A. Hepatitis A vaccine has been incorporated into expanding the national immunization plan, and free vaccination is given to children in August. Key groups such as food production and operation practitioners, staff members of childcare institutions, and collective living personnel shall also vaccinate hepatitis A vaccine. There are already liver vaccines in my country and can voluntarily vaccinate at their own expense.
Most of the hepatitis A and Koba are acute viral hepatitis. After timely treatment, most patients can fully recover within half a year. A few patients with severe illness are risk of liver failure and should be paid attention to.
There are currently no hepatitis C vaccines, but effective measures can be taken to cut the transmission path. Hepatitis C can prevent it.
Do not share needles or other tattoos, punctures and other tools with others, and do not share shaving knives, toothbrushes, etc. with others; use condoms correctly to avoid unsafe behavior; reject drugs, do not share needle injection drugs ; Prevent illegal mining and blood supply; avoid unnecessary injection, blood transfusion, and use of blood products; to form a regular medical and health institution for injection, blood transfusion, and use of blood products, it can greatly reduce the risk of infection with hepatitis C virus.
Hepatitis C is also easily turned into chronic. After the treatment of anti -virus treatment of full treatment, most patients can cure.
Ding hepativirus can only be infected only at the same time as hepatitis B virus or hepatitis B virus infection. Safe and effective hepatitis B vaccine can protect the infection of Dingri virus infection.
Patients with viral hepatitis should follow the doctor’s order, conduct standardized treatment, and do not stop drugs or trust false advertisements by themselves. Finally, all patients with viral hepatitis and ordinary people should avoid alcoholism, smoking, unreasonable medication and other behaviors to aggravate liver damage.
It is believed that in the near future, hepatitis will eventually be eliminated.
