Epidemiology Hepatitis B affects 1 in 3 people worldwide (Hepatitis B Foundation [HBF], 2014). A vaccine has been available for over 30 years, yet it is the ninth leading cause of death worldwide (HBF, 2014). The epidemiology of hepatitis B, the role of the community health nurse along with the knowledge about what is being done to combat and reduce the impact of the virus gives a comprehensive look at hepatitis B. Hepatitis B virus (HBV) is a DNA virus, and belongs to the Hepadnaviridae family
Hepatitis B What is hepatitis B? Hepatitis means the inflammation of the liver. Hepatitis B, “formerly called serum hepatitis (Richard Adler)”, is caused by a serious liver infection with the hepatitis B virus (HBV) and the infection has two phases: acute and chronic (eMedicineHealth). Acute hepatitis B is short-term and occurs after being exposed to the virus and only few develop fulminant hepatitis which is very severe and life threatening. Chronic hepatitis can lead to “liver failure, liver
MMWR Paper on Hepatitis B Microbiology 212-A April 27, 2012 Hepatitis B virus (HBV) is a DNA virus that affects the liver and belongs to the Hepadnaviridae group (Takkenberg, Weegink, Zaaijer, & Reesink, 2010). According to an article in Vox Sanguines, an international journal of transfusion medicine, (Takkenberg, Weegink, Zaaijer, & Reesink, 2010) “about 400 million people worldwide are chronically infected with HBV, and 2 billion people have serological evidence of past or present
Epidemiology of Hepatitis B Hepatitis B is a disease that affects many people worldwide and can cause serious and potentially fatal complications. This paper will provide an overview of this disease, including demographic information, while discussing contributing determinants of health, the implications of the epidemiological triangle as it relates to the Hepatitis B Virus (HBV), the role of the community health nurse, as well as identify a national organization that addresses the disease and how
Hepatitis B is a serious liver virus, some people with Hep B can become chronic and it can last up to six months or longer. It increase risk of having liver failure, liver cancer, and cirrhosis. People that are infected with Hep B as adults recover fully however infant or children are the ones who are more likely to have chronic infections Hepatitis B has symptoms, cause, risk factor and complications although, there is vaccine that can prevent Hep B, but there is really not cure for it. If you are
Hepatitis B can be prevented with a highly effective vaccine, but this year ten to thirty million people will become infected with the hepatitis B virus. I feel that because this disease is preventable, only knowledge can help reduce the number of people infected. Hepatitis B is a serious liver disease caused by the hepatitis B virus. This virus is a blood-borne pathogen. It is one hundred times more infectious than HIV. “Hepatitis B is one of the most frequently
Hepatitis B, C Hepatitis B virus (HBV) belongs to the Hepadnarvirus family. The virus particle consists a lipid envelope that contains surface antigens, HBsAg, a core composed of protein, viral DNA, and polymerase. Theses virions are approximately 40 nm in diameter, which are known as one of the smallest enveloped animal viruses. It infects hepatocytes, also known as Dana particles. The genome of HBV is circular, partly double stranded, and approximately 3,200 nucleotides long. Dr. Baruch Blumberd
Hepatitis B Virus Characteristics: Hepatitis B Virus (HBV) is a double-stranded DNA virus in the Hepadnaviridae family. The infectious particle is 42nm in diameter, with a genome 3200 nucleotides long. It has an outer envelope and an icosahedral nucleocapsid, which contains viral DNA polymerase and has a diameter of 27nm. The envelope contains the HBV surface antigen (HBsAg); this is the molecule to which anti-HBV antibodies are directed. The non-infectious hepatitis B particles
Introduction Hepatitis B virus (HBV) attacks the liver and may cause long-term liver diseases. The HBV vaccination program was launched in 1982, and the vaccines work 95% of the time in preventing infection among non-immunodeficiency people (1). However, human immunodeficiency virus (HIV) infected patients are usually more prone to HBV, as these two viruses share the common modes of spread, such as sexual transmission (2). To prevent co-infection, HIV patients are recommended to have HBV vaccine
