Hepatitis B Hepatitis B virus (HBV) belongs to the Hepadnarvirus family. The virus particles consist of a lipid envelope that contains surface antigens, HBsAg, a core made of proteins, viral DNA, and polymerase. Theses virions are approximately forty 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 (HBV) is a common disease in many parts of the world. It is a preventable disease through necessary immunization. However, there are currently millions of people who are still living with this disease worldwide. Chronic hepatitis B is considered to be a dangerous disease because it does not present any symptoms nor a person would feel sick. A blood test for liver enzymes may present within normal ranges that, by the time a person suffer from abdominal pain or the appearance of abdominal
HBV:- Hepatitis B virus is a pathogen which causes disease hepatitis B. It infects liver of hominoidae which includes humans resulting in inflammation which causes hepatitis. It was originally called as serum hepatitis which have epidemics in Asia and Africa. It is also endemic in some parts of China. Above than two billion people is infected by hepatitis B virus. It included three hundred and fifty million chronic patients of virus. HBV is transmitted through body fluids or by infectious blood.
Introduction Hepatitis B, an infectious disease caused by the Hepatitis B virus (HBV, a DNA virus), was formerly called serum hepatitis, inoculation hepatitis and post-transfusion hepatitis. Infection with HBV may result in acute, fulminant or chronic hepatitis, sometimes even resulting in a chronic asymptomatic carrier state, apart from hepatocellular carcinoma and liver cirrhosis (Davis 179). The disease is transmitted when an individual comes in contact with infected blood or objects. It may
Hepatitis B virus (HBV) is a severe and common virus that has infected ‘more than two billion people alive today at some point in their life.’1 It is a hepadanavirus that interferes with the liver functions as it replicates in the hepatocytes (liver cells) and induces a immune response that is responsible for the inflammation of liver.2 Viruses are not motile, which means that HBV is also sessile and does not form spores. The spherical virion, is called a Dane Particle3 that is 42nm in diameter binds
Hepatitis B Hepatitis B is a disease of the liver caused by the virus HBV. Known as serum hepatitis or “the silent infection", it could cause liver cirrhosis or liver cancer. Hepatitis B can be as severe as a minor illness enduring a few weeks to a serious, lifetime disease. Hepatitis B is commonly contracted through blood, semen, or other body fluids from an individual infected with the Hepatitis B virus into the body of someone who is not infected by Hepatitis B. Infection of the Hepatitis B can
1 Hepatitis B 1.1 Hepatitis B virus Hepatitis B (HBV) is a blood-borne viral liver infection with various routs of transmission. It is one of the most common and serious liver diseases in the world and a leading cause of death worldwide. If the infection becomes chronic the infection can lead to liver failure, cirrhosis and hepatocellular carcinoma. The HBV virus is transmitted through contact with contaminated blood or other body fluids such as serum, semen and salvia. The condition following the
Author ID: 4042 Word Count: 925 Proposed species: Hepatitis B Proposed action: Eradication What is Hepatitis B? Hepatitis B is a viral infection transmitted by humans that affects the Liver. There are two types of Hepatitis B: acute and chronic. Acute hepatitis B is short term and only lasts for a short amount of time. Chronic hepatitis B is long term and is a lifelong illness. This disease is passed from an infected person to an uninfected person through exchange of bodily fluids such as blood
Hepatitis B Hepatitis B is a DNA viral infection that causes damage and inflammation to the liver. It was first discovered in 1965 by Dr. Baruch Blumberg. The HBV virus is very contagious and is even thought to be the most serious form of viral hepatitis and the most common viral infection on Earth. “HBV is 100 times more infectious than HIV.” (Green, 2002, pg. 7) The virus can survive for about one week outside the body on a dry surface. According to Green (2002, pg. 7), “One in twenty Americans
Hepatitis B virus can cause an infection either in the form of a short, acute illness or a chronic, long-lasting condition that affects the liver. Hepatitis B can cause serious disease in infants, so pregnant mothers who carry the virus must try to protect their babies by being screened and having their babies vaccinated after birth. What Is Hepatitis B? Hepatitis B virus is an organism that infects the liver, causing either a short, acute illness or a chronic, long-lasting disease. A baby who gets
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 are composed
Hepatitis B is a virus that attacks the liver. It can lay dormant for years with little to no symptoms or you can start having symptoms in as little as a few weeks. It can not only affect the liver, but also the oral cavity as well. Appearing anywhere from one to four months, signs and symptoms of Hepatitis B can occur. Signs and symptoms range from mild (intolerance to alcohol, dark urine, nausea and vomiting, and weakness and fatigue) to severe (loss of appetite, jaundice, abdominal pain, and
Brief description and explanation of disorder: Hepatitis B is an infection of ones liver which prevents it from working well. The infection can also cause scarring of the organ. It can cause cancer and liver failure if not treated right away. The good news about this disorder is that in most cases, the disorder does not last very long. Once your body fights off the disease, you become immune to it for the rest of your life. Hepatitis b is a DNA virus. It is caused when people come in contact with
HEPATITIS B VIRUS Hepatitis B Virus (HBV) is a virus that attacks the liver. The virus is transmitted through blood and bodily fluids. This can occur through direct blood-to-blood contact, unprotected sex, use of contaminated needles, and from an effected mother to her newborn during the delivery process. The majority of people do not have noticeable symptoms when they are first infected with the HBV. People who do not know they are infected with the HBV, their body can respond in different ways
Opening: Hepatitis B is a viral liver disease that can cause mild to severe illness. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. Body: Hepatitis B is a contagious liver infection caused by the hepatitis B virus. Hepatitis B can be acute or chronic. Every type of hepatitis can increase your risk of liver scarring and liver failure. Hepatitis B infection may be either acute (short-lived) or chronic (long lasting): • Acute
Background of Hepatitis B infection Hepatitis B virus infection is caused by a DNA virus belonging to the hepadnaviridae family of viruses. Approximately 2.2 million people in the United States of America are infected with Hepatitis B virus. Many of these patients, though they appear healthy, continue to spread the virus to others. Hepatitis B virus infection can be transmitted in the following ways: contact with contaminated blood (shared needles), sexual contact, and from mother to child. Unlike

Within the healthcare system, nurses form the largest professional group and have been recognised as the most trusted profession by the public (GALLUP). Thus, it is our duty as future nurses to acknowledge that being safe is not only vital for the health and wellbeing of patients, but for the nurses themselves. Today, I will be discussing how the safety of nurses is not only vital to their patients but to themselves as well. Hence, I have chosen to discuss four nursing competencies stated in the
Biological hazards refer to organisms or organic matters produced by these organisms that are harmful to human health. These include parasites, viruses, bacteria, fungi and protein. In general, there are three major of routes of entry for these micro-organisms into our body, i.e. through the respiratory system, transmission through contact with body fluids of the infected or contact with contaminated objects. According to WHO , Among the 35 million health workers worldwide, about 3 million experience
A risk can be defined as a high or low chance that someone could be harmed and how serious that harm can be. The development of risk management strategies is essential for the prevention of both hepatitis B and hepatitis C in the healthcare setting. The risk management process involves the identification of the risk, the analysis of the risk, the elimination or reduction of the risk, the ongoing evaluation of the risk management and efficient occurrence management of the accidents or infections that
