Hepatitis B? HEPATITIS B Hepatitis B Is a Contagious Liver Disease That Results from Infection with the Hepatitis B Virus
What is Hepatitis B? HEPATITIS B Hepatitis B is a contagious liver disease that results from infection with the Hepatitis B virus. When first infected, a person can develop Are you at risk? an “acute” infection, which can range in severity from a very mild illness with few or no symptoms to a serious condition requiring hospitalization. Acute Hepatitis B refers to the first 6 months after someone is exposed to the Hepatitis B virus. Some people are able to fight the infection and clear the virus. For others, the infection remains and leads to a “chronic,” or lifelong, illness. Chronic Hepatitis B refers to the illness that occurs when the Hepatitis B virus remains in a person’s body. Over time, the infection can cause serious health problems. How is Hepatitis B spread? Hepatitis B is usually spread when blood, semen, or other body fluids from a person infected with the Hepatitis B virus enter the body of someone who is not infected. This can happen through having sex with an infected partner; sharing needles, syringes, or other injection drug equipment; or from direct contact with the blood or open sores of an infected person. Hepatitis B can also be passed from an infected mother to her baby at birth. Who should be tested for Hepatitis B? Approximately 1.2 million people in the United States and 350 million people worldwide have Hepatitis B. Testing for Hepatitis B is recommended for certain groups of people, including: Most are unaware of their infection. ■ People born in Asia, Africa, and other regions with moderate or high rates Is Hepatitis B common? of Hepatitis B (see map) Yes. -

Understanding Human Astrovirus from Pathogenesis to Treatment Abstract While human astroviruses (HAstV) were discovered nearly 45 years ago, these small positive-sense RNA viruses remain critically understudied. These studies provide fundamental new research on astrovirus pathogenesis and disruption of the gut epithelium by induction of epithelial-mesenchymal transition (EMT) following astrovirus infection. Here we characterize HAstV-induced EMT as an upregulation of SNAI1 and VIM with a down regulation of CDH1 and OCLN, loss of cell-cell junctions most notably at 18 hours post-infection (hpi), and loss of cellular polarity by 24 hpi. While active transforming growth factor- (TGF-) increases during HAstV infection, inhibition of TGF- signaling does not hinder EMT induction. However, HAstV-induced EMT does require active viral replication. -

There’s lots of incorrect information and it’s easy to be overwhelmed and confused. On this page, we’ll try to clear some things up. It is important that information is helpful, clear, and checked and confirmed by experts. Please share the following information – it comes from health and medical specialists. COVID-19 is an acronym that stands for COronaVIrus Disease 2019. You might hear it called coronavirus, corona, SARS-CoV-2, or even rona. We’ll call it COVID-19 or coronavirus in this FAQ but all these terms are essentially talking about the same thing and we’ll explain them at the bottom. You’ll also hear new or unfamiliar terms like “social distancing,” “physical distancing,” “self-isolation,” and “quarantine”. These terms and what they actually mean can become confusing so we’ve including a glossary at the bottom of this FAQ. This virus has only been known about since around December 2019 so it’s all very new, information changes quickly, and we’re all learning day-by-day and week-by-week. Compare COVID-19 to hep B which we’ve known about since the 1980s and hep B even earlier in the 1960s! We’ll regularly update this page as new information comes to light. -

Hepatitis B Virus (HBV)
HEPATITIS B AND COLLEGE STUDENTS Hepatitis B is a liver disease that results from infection with the Hepatitis B virus (HBV). It can range in severity from a mild illness lasting a few weeks to a serious, lifelong illness. Hepatitis B is usually spread when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact with an infected person or sharing needles, syringes, or other drug-injection equipment. Hepatitis B can also be passed from an infected mother to her baby at birth. Hepatitis B can be either acute or chronic. Acute HBV infection is a short-term illness that occurs within the first 6 months after someone is exposed to the Hepatitis B virus. Acute infection can — but does not always — lead to chronic infection. Chronic HBV infection is a long-term illness that occurs when the Hepatitis B virus remains in a person’s body. Chronic HBV is a serious disease that can result in long-term health problems, and even death. The best way to prevent HBV infection is by getting vaccinated. How common is hepatitis B in the United States? About 800,000 to 1.4 million persons in the United States have chronic HBV infection. Each year 38,000 more people, mostly young adults, get infected with HBV and almost 2,000 people die from chronic HBV. How is hepatitis B spread? Hepatitis B is spread when blood, semen, or other body fluid infected with the hepatitis B virus enters the body of a person who is not infected. -

Viral Hepatitis B: Introduction
Viral Hepatitis B: Introduction “Viral hepatitis," refers to infections that affect the liver and are caused by viruses. It is a major public health issue in the United States and worldwide. Not only does viral hepatitis carry a high morbidity, but it also stresses medical resources and can have severe economic consequences. The majority of all viral hepatitis cases are preventable. Viral hepatitis includes five distinct disease entities, which are caused by at least five different viruses. Hepatitis A and hepatitis B (infectious and serum hepatitis, respectively) are considered separate diseases and both can be diagnosed by a specific serologic test. Hepatitis C and E comprise a third category, each a distinct type, with Hepatitis C parenterally transmitted, and hepatitis E enterically transmitted. Hepatitis D, or delta hepatitis, is another distinct virus that is dependent upon hepatitis B infection. This form of hepatitis may occur as a super-infectionin a hepatitis B carrier or as a co-infection in an individual with acute hepatitis B. Hepatitis viruses most often found in the United States include A, B, C, and D. Because fatality from hepatitis is relatively low, mortality figures are a poor indicator of the actual incidence of these diseases. The Centers for Disease Control and Prevention estimated that approximately 400,000–600,000 people were infected with viral hepatitis during the decade of the 1990s. Hepatitis plagued mankind as early as the fifth century BC. It was referenced in early biblical literature and described as occurring in outbreaks, especially during times of war. Toward the end of the nineteenth century, hepatitis was thought to occur as a result of infection of the hepatic parenchyma. -
