B of the "root" of the number of broken?

Vaccination, hepatitis B short of the number of Vaccination to control viral hepatitis epidemic the best way. Since 1992 China has its own production of live attenuated hepatitis A vaccine, hepatitis A incidence decreased. If the city of Jinan in Shandong Province, according to CDC statistics, in 1991 the city's incidence of hepatitis A total of 4648 people, by 2002 the number of incidence of only 249 people. Funing Xian, Jiangsu Province in 1991 after the flood, as high prevalence of hepatitis A 552.5/10 million. From 1992 to 1994, the population of the province to carry out gamma globulin inoculation, beginning in 1995 to carry out hepatitis A vaccination of children, is the main target of over 1 year old children and vulnerable persons, in 2003 occurred in the same flood, and only the incidence of hepatitis A 18.2/10 million. This year, many parts of our country will be immune hepatitis A vaccine into the planning, the incidence of hepatitis A will be further reduced. Maternal and Child block, the hepatitis B "root" of the number of broken Hepatitis B virus can be infected with the human body in many ways, such as blood transfusion, injection, treatment equipment, mother to child transmission, sexual contact and live in close contact, and so on. Mother to child transmission of hepatitis B in China is the main route of transmission. If you do not accept the vaccine to prevent hepatitis B, hepatitis B mothers of children born to 60% in two years may be infected with hepatitis B virus; e antigen-positive mothers of children born to 95% in one year on the surface antigen positive. Now the mother-to-child infection of hepatitis B virus transmission-blocking measures more and more mature and perfect. Mother of a child born to hepatitis B by injection of hepatitis B vaccine plus hepatitis B immunoglobulin for maternal and child block for higher hepatitis B virus DNA of the gene of hepatitis B mothers, but also in the latter part of pregnancy appropriate anti-viral treatment, Reduce the mother's viral load in the body, blocking the effect of increasing maternal and child. After blocking mother-to-child hepatitis B mothers of children born to hepatitis B virus infection rate decreased significantly. Anti-viral treatment, a good number of chronic hepatitis Serious harm to human health of chronic hepatitis B and hepatitis C currently has an effective anti-viral treatment. In the early 1990s began to interferon for the treatment of chronic hepatitis B and hepatitis C, 40% to 60% of hepatitis C and 25% to 30% of the efficacy of hepatitis B has been made, even to clear the virus. Later, in the treatment of hepatitis C, interferon for ribavirin found a "helper" to further enhance the efficacy of HCV. The treatment of hepatitis B virus is by leaps and bounds. Since the 1999 listing of lamivudine, adefovir, entecavir and telbivudine listed one after another, the more hepatitis B treatment. After anti-viral treatment, 60% to 90% of patients with chronic hepatitis viruses can alleviate or control. A foreign doctor on more than 900 patients with chronic hepatitis B had a 7-year retrospective study found that without anti-virus treatment in patients with liver cancer in 7 years, the incidence rate of 11.2 percent, while the use of anti-retroviral therapy in patients with liver cancer The incidence of only 2.3 percent on anti-retroviral therapy significantly improved the prognosis of hepatitis B, liver disease slowed progress. This year on May 19 was the first World Hepatitis Day. World Hepatitis Day by the Geneva-based non-governmental organizations - World Hepatitis Alliance (WHA) join the World Health Organization, other United Nations organizations, Red Cross, an open society institute, the Gates Foundation, among others, co-sponsored. At that time, all over the world's five continents, more than 200 organizations will be synchronized, to arouse the people of the world of viral hepatitis prevention and treatment of concern and importance to raise public awareness of viral hepatitis.
