Abstract. Hepatitis B virus (HBV) currently infects an estimated population of 2 billion individuals in the world, including 400 million people with chronic HBV infection. HBV virology, replication and the host's immune response to HBV infection contribute to different infection outcomes. Acute hepatitis HBV infection is self-limiting but it ...

Hepatitis B vaccine is highly effective in preventing both vertically and horizontally acquired chronic HBV infection [3,4,5]. Hepatitis B vaccine is available in healthcare system in Vietnam including health centers and clinics with monovalent vaccine since 2003 and pentavalent DPT-Hib-Hepatitis B vaccine for children since 2010 .

Makoto Mayumi. To study of the risk of the hepatitis B virus infection from HBsAg carriers to their families, their spouses and children of HBsAg carriers with HBeAg or anti-HBe were examined for ...

Introduction. Globally, ~290 million people are chronically infected with hepatitis B virus (HBV), and more than 800,000 people consequently die each year from liver cirrhosis or liver cancer ().In response to the United Nations Sustainable Development Goals, which aim to eliminate viral hepatitis as a public health threat by the year 2030 (), HBV infection is receiving increasing recognition ...

Introduction. Hepatitis B virus (HBV) is a global public health concern particularly in sub-Saharan Africa, Western Pacific Region, and areas of Eastern Europe, with the prevalence ranging from 5-10%, and it is ranked the 15th cause of death in all-cause global mortality [1-4].Approximately 15-25% of HBV infected people die due to liver cirrhosis, liver failure, or hepatocellular ...

The natural history of an hepatitis B virus (HBV) infection. Infection with HBV typically results in an acute, self-clearing infection. Alternatively, infected individuals could develop a chronic infection, which typically follows a long-term course in which the virus replicates at high levels, followed by immune-mediated control of viral ...

Introduction: Hepatitis B (HB) is a serious infection that affects liver and caused by hepatitis B virus (HBV). HB is a serious global public health problem and the health professionals are most at risk. It is contagious and easy to be transmitted from one infected individual to another by blood to blood contact, mother to child, unprotected sexual intercourse, sharing of eating utensils and ...

Hepatitis B is a global epidemic that requires carefully orchestrated vaccination initiatives in geographical regions of medium to high endemicity to reach the World Health Organization's elimination targets by 2030. This study compares two widely-used deterministic hepatitis B models-the Imperial H …

1. Introduction. Hepatitis B virus (HBV) infection is a major public health problem, which has caused a high direct and indirect disease burden worldwide [Citation 1].The global burden of HBV infection is unevenly distributed, with particularly high prevalence in some countries in Africa and Southeast Asia [Citation 2].However, persistent HBV infection can lead to varying degrees of liver ...

Introduction. Hepatitis B (HB) is a serious blood born infection that affects the liver and caused by hepatitis B virus (HBV). It is infectious and the most common cause of chronic hepatitis, liver cirrhosis and hepato-cellular carcinoma .Hepatitis B is a very important public health problem affecting almost 10% of the world population .According to 2009 WHO report, about 2 billon people are ...

Hepatitis B virus (HBV) infection is a major public health problem, with an estimated 296 million people chronically infected and 820 000 deaths worldwide in 2019. Diagnosis of HBV infection requires serological testing for HBsAg and for acute infection additional testing for IgM hepatitis B core antibody (IgM anti-HBc, for the window period ...

Introduction Hepatitis B infection remains a public health threat associated with undesirable statistics of morbidity and mortality. Good knowledge, attitude and practice (KAP) of hepatitis B infection (HBI) prevention are essential for HBI control. However, there is limited evidence concerning the KAP of HBI prevention among nursing students, who are significantly exposed to HBI.

Hepatitis B virus (HBV) infection creates a global health burden with significant morbidity and mortality. Healthcare workers, including nurses and midwives, are at higher risk of acquiring the disease. While health-related behaviours are affected by different aspects of knowledge, attitude, and practices (KAP), there are few studies examining the KAP level of healthcare workers towards HBV ...

These attributable fractions can be inferred from published studies on the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection among a representative group of patients with cirrhosis. The most recent systematic review reporting on the attributable fraction of viral hepatitis among patients with cirrhosis was published in ...

Epidemiology. In 2019, 296 million people were positive for hepatitis B surface antigen (HBsAg) worldwide, and the global prevalence of CHB infection was approxi mately 3·5%.2 The prevalence of HBsAg or CHB infection varies widely in diferent parts of the world (figure 1).3 In all countries, both incidence of acute and prevalence of chronic ...

Thesis ( M Med (Virological Pathology))--University of Limpopo, 2010. Introduction: Hepatitis B virus (HBV) is a serious problem worldwide causing various liver diseases such as chronic hepatitis and hepatocellular carcinoma (HCC).

Hepatitis B is a chronic infection and is the main health concern especially in Asia, Africa, Southern Europe and Latin America and around two billion individuals are infected with HBV on the globe, among them 400 million are suffering from chronic HBV infection.

Chronic hepatitis B disproportionately affects Asian Americans. Although Asians make up only 4.2% of the total United States (U.S.) population, they account for more than half of those infected with hepatitis B. If left untreated, chronic hepatitis B could lead to cirrhosis, liver damage, and liver cancer.

Overview . Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease. The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expanded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child ...

Abstract. Despite the advances in therapy, hepatitis B virus (HBV) and hepatitis C virus (HCV) still represent a significant global health burden, both as major causes of cirrhosis, hepatocellular carcinoma, and death worldwide. HBV is capable of incorporating its covalently closed circular DNA into the host cell's hepatocyte genome, making ...

WHO has released new Guidelines on prevention, diagnosis and treatment of chronic hepatitis B (HBV) infection at the 2024 Asian Pacific Conference for the Study of Liver Disease (APASL) in Kyoto, Japan. These guidelines provide a substantial simplification and expansion of eligibility for treatment to overcome barriers in access to HBV testing and treatment.

Discontinuation of anti-hepatitis B therapy, including VEMLIDY, may result in severe acute exacerbations of hepatitis B. Patients who discontinue VEMLIDY should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping treatment. If appropriate, resumption of anti-hepatitis B therapy may be

Viral hepatitis has emerged as a major public health problem throughout the world affecting several hundreds of millions of people. Viral hepatitis is a cause of considerable morbidity and mortality in the human population, both from acute infection and chronic sequelae which include, in the case of hepatitis B, C and D, chronic active hepatitis and cirrhosis.

Second, bNAbs from this individual targeted three different regions of the virus' E2 protein, the front layer, as well as a back layer and a b-sandwich. The data suggests that a hepatitis C virus vaccine should elicit bNAbs to all three regions of the E2 protein rather than just one region of the virus, Flyak said.
