Understanding Hepatitis and preventing exposure in the workplace.
The word “Hepatitis” means inflammation of the liver. Hepatitis is caused by viruses, which are small organisms that can cause disease. There are many different types of viruses that cause hepatitis, and it is possible to be infected with more than one hepatitis virus at the same time. Each virus is completely different from the other viruses, all are prevented and transmitted differently, and each causes different symptoms.
Understanding how the different types of hepatitis can spread is the first key to prevention. Hepatitis has many ways of invading the body but there are ways we can protect ourselves from contracting this disease.
There are 5 types of hepatitis: A, B, C, D, and E. There are two main ways that hepatitis can pass from person to person: the most common being, coming in contact with infected blood or other body fluids, and contact with feces that is infected.
Hepatitis A and E is transmitted via the fecal-oral route. It is often caught by eating foods or drinking water that is contaminated with the feces of a Hepatitis A infected person, so hepatitis A is a great concern for the food industry and there is a vaccine available for Hepatitis A.
The virus for hepatitis A and E , also spreads and infections often occur in conditions of poor sanitation, overcrowding, and ingestion of shellfish cultivated in polluted water is associated with a high risk of infection. The virus is resistant to detergent, acid (pH 1), solvents, drying, and temperatures up to 60 °C.
Hepatitis B is found is in blood, saliva, vaginal fluid, or semen of an infected person. It is transmitted through unprotected sex, insect bites, and through blood-to-blood contact. Sexual t...

Research around stigma and discrimination in health related settings has implicated universal precautions as a means by which health care workers discriminate against patients. Particularly the use of universal precautions when working with people with HIV and/hepatitis C has been inconsistent and implicated with feelings of stigmatization reported by those populations. Health- cased social research reveals that by not applying universal precautions universally, as is the purpose, health professionals are instead making judgments based on individual’s health status. It is speculated that this differential approach to care stems stigma towards HIV, hepatitis C, rooted largely in fears and misconceptions around transmission and assumptions about patient lifestyle and risk.
Autoimmune hepatitis is a chronic inflammatory disorder characterized by periportal inflammation, elevated immunoglobulins, autoantibodies, and a dramatic response to immunosuppression. Autoimmune hepatitis occurs when the body's immune system, which ordinarily attacks viruses, bacteria and other pathogens, instead targets the liver. This attack on your liver can lead to chronic inflammation and serious damage to liver cells. Just why the body turns against itself is unclear, but researchers think
Liver Disease (Hepatitis) There are many different types of diseases that dental hygienist have to be aware of. It is important to know the basic information about the disease and how the disease affects the patient’s oral cavity as well as how to treat the patient. This paper will be addressing liver disease and more specifically, liver disease caused by hepatitis. “The term liver disease applies to many diseases and disorders that cause the liver to function improperly or stop functioning.” (U
Hepatitis is a serious illness that most commonly affects adults over the age of 40 years old. It can occur in teenagers and children too, but this is generally more rare. Because it stems from a highly-contagious virus, it is crucial that all people who are at risk for contracting it, or who might already have it, read the following information about what the types of hepatitis are, what symptoms it causes, and how it can be prevented. Types of Hepatitis There are three basic types of hepatitis
Advancements in medicine and technology have allowed scientists to discover new diseases as well as treatments for some. Autoimmune hepatitis is among the diseases where a cure in unavailable. In 1950, Waldenström discovered autoimmune hepatitis in young women (Wolf). Originally called lupoid hepatitis, lupus was thought to be the cause of autoimmune hepatitis (Frey, Longe, and Ricker). If symptoms of AIH are detected early, treatment for better life quality can be accomplished with medication instead
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
Malaria is a common disease in a hot tropical area and it affects about 300 million people worldwide. There are four types of parasites that cause malaria in humans. Among the types of species Plasmodium falciparum is most common in Africa region and it can cause deadly form of disease. The Plasmodium vivax which is the second type of species is not life-threatening form of malaria. Plasmodium ovale also causes malaria. The system malaria affect most is the immune system. Malaria undergoes a complex
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

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
infections are: hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV). Another infection which has more recently increased in prevalence is methicillin-resistant Staphylococcus aureus (MRSA). These infections are all treated differently. Each infection has its own symptoms, classifications, and incubation periods. These infections are transmitted in very similar fashions, but they do not all target the same population. Hepatitis B was the first of the hepatitis viruses to be
(1436). When individuals lack these specific proteins, the human body cannot clot properly therefore, forming hemophilia. Hemophilia is also a genetic disorder, meaning this disorder can be passed down from the parents to their offspring. In most types of hemophilia, the disorder is located on the X chromosome. Disorders that are located on the X chromosomes will appear in males more than females. The reason behind this
3.3.2.2. Hepatitis This is the inflammation of the liver. The hepatitis virus is a major cause of hepatitis in humans. However, the condition can be induced by various infections and medical conditions, such as excess intake of alcohol, medications, toxins, and autoimmune disease. There are five types of hepatitis virus which include: hepatitis A, hepatitis B, hepatitis C, hepatitis D, hepatitis E. (“Hepatitis | NIH: National Institute of Allergy and Infectious Diseases,” 2015) 3.3.2.2.1. Causes
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
do research on Hepatitis C for recognition targeted towards technical publications as JAMA, New England Journal Of Medicine etc. Hepatitis C (HCV) causes inflammation of the liver and can cause liver damage leading to cirrhosis. Occasionally, liver cancer may develop. First called non-A non-B hepatitis, hepatitis C was discovered in the early 1970’s, but it wasn’t until 1989 that testing for specific antibodies to the virus began. Each year, 15,000 Americans contract hepatitis C, which is a
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 Hepatitis In modern society when a person gets sick with the flu or a cold they will usually go about their normal routine with the exception of a sneeze or a cough throughout the day. Sometimes things can be more than what they appear to be. The symptoms start out like the flu with coughing, fever, aches, and vomiting. However, the disease gradually worsens with symptoms of extreme weakness and excruciating abdominal pain. By then it is usually too late when the person finds out that
