US FDA/CFSAN - Bad Bug Book - Hepatitis E Virus Hepatitis E Virus (HEV) has a particle diameter of 32-34 nm, a buoyant density of 1.29 g/ml in KTar/Gly gradient, and is very labile. Hepatitis caused by HEV is clinically indistinguishable from hepatitis A disease. Outbreaks of enterically transmitted non-A, non-B hepatitis occurred in 1985 and 1986 at refugee camps for Ethiopians in Somalia and the Sudan. vm.cfsan.fda.gov /~mow/chap32.html   (671 words)

Hepatitis E - Wikipedia, the free encyclopedia Hepatitis E is an acute viral hepatitis (liver inflammation) caused by infection with a virus called hepatitis E virus (HEV). Hepatitis E occasionally develops into an acute severe liver disease, and is fatal in about 2% of all cases. Hepatitis E is prevalent in most developing countries, and not uncommon in any country with a hot climate. en.wikipedia.org /wiki/Hepatitis_E   (719 words)

Hepatitis - Wikipedia, the free encyclopedia Hepatitis is characterised by fatigue, malaise, joint aches, abdominal pain, vomiting 2-3 times per day for the first 5 days, loss of appetite, dark urine, fever, hepatomegaly (enlarged liver) and jaundice (icterus). Hepatitis E produces symptoms similar to hepatitis A, although it can take a fulminant course in some patients, particularly pregnant women; it is more prevalent in the Indian subcontinent. Alcoholic hepatitis is characterized by a variable constellation of symptoms, which may include feeling unwell, enlargement of the liver, development of fluid in the abdomen ascites, and modest elevation of liver blood tests. en.wikipedia.org /wiki/Hepatitis   (1839 words)

WHO | Hepatitis E Hepatitis E (HEV) was not recognized as a distinct human disease until 1980. Hepatitis E is caused by infection with the hepatitis E virus, a non-enveloped, positive-sense, single-stranded RNA virus. Hepatitis E is a viral disease, and as such, antibiotics are of no value in the treatment of the infection. www.who.int /mediacentre/factsheets/fs280/en   (785 words)

Hepatitis E in Developed Countries Hepatitis E virus (HEV) is a major cause of enterically transmitted non-A, non-B hepatitis in poor countries, often presenting as large outbreaks of hepatitis in which fecally contaminated water is usually implicated. Hepatitis E virus (HEV), the major etiologic agent of enterically transmitted non-A, non-B hepatitis worldwide, is a spherical, non-enveloped, single stranded RNA virus that is approximately 32 to 34 nm in diameter. Prudent hygienic practices that may prevent hepatitis E and other enterically transmitted diseases among travelers to developing countries include avoiding drinking water (and beverages with ice) of unknown purity, uncooked shellfish, and uncooked fruits or vegetables that are not peeled or prepared by the traveler. www.natap.org /2003/feb/020403_1.htm   (1334 words)

Hepatitis Encyclopedia of Alternative Medicine - Find Articles Hepatitis A is an inflammation of the liver caused by the hepatitis A virus (HAV). Hepatitis B occurs in both rapidly developing (acute) and long-lasting (chronic) forms, and is one of the most frequent chronic infectious diseases worldwide. Hepatitis C is generally mild in its early, acute stage, but it is much more likely to produce chronic liver disease than hepatitis B. About two of every three persons who are infected by HCV may continue to have the virus in their blood and become carriers, who can transmit the infection to others. www.findarticles.com /p/articles/mi_g2603/is_0004/ai_2603000417   (929 words)

txt001sjd: Molecular biology and pathogenesis of hepatitis E virus A curious feature of hepatitis E is the unusually high rates of mortality that are observed in pregnant women, in whom the disease is exacerbated by the development of fulminant liver disease. In most hepatitis E outbreaks, the highest rates of clinically evident disease have been reported in young to middle-age adults; the lower disease rates in younger age groups might be the result of anicteric (i.e. Hepatitis E is not a significant health problem in countries that have the technological capabilities and the funds to carry out front-line biological research. www-ermm.cbcu.cam.ac.uk /99001271h.htm   (7035 words)

Home | aHealthyme.com The hepatitis E virus (HEV) is a common cause of hepatitis that is transmitted via the intestinal tract, and is not caused by the hepatitis A virus. Hepatitis E never becomes a chronic (long-lasting) illness, but on rare occasions the acute illness damages and destroys so many liver cells that the liver can no longer function. In the United States hepatitis E is not a fatal illness, but elsewhere about 1-2% of those infected die of advanced liver failure. www.ahealthyme.com /article/gale/100084690   (723 words)

PIGS, PEOPLE AND HEPATITIS E Hepatitis E viruses are a major cause of outbreak and sporadic cases of human viral hepatitis in tropical and sub-tropical countries (Yarbough 1999). Hepatitis E in most patients is a moderately severe icteric (jaundice) disease with a self-limited course similar to that seen in hepatitis A infections. Hepatitis E virus is transmitted principally by the fecal-oral route. www.arserrc.gov /mfs/HotSeat2.htm   (1729 words)

Hepatitis E Virus, Hepatitis E Virus Infection, HEV Virus Infection More than 50% of acute viral hepatitis occurring in some developing countries appears to be unrelated to infection by HAV or HBV and accumulating evidence suggests that a high proportion of this NANBH is enterically transmitted (Hepatitis E). Hepatitis E disease occur in both sporadic and epidemic forms and is primarily associated with the ingestion of faecally contaminated drinking water. Hepatitis E was first documented in New Delhi in 1955 when 29000 cases of icteric hepatitis occurred following the contamination of the city's drinking water. virology-online.com /viruses/HepatitisE.htm   (740 words)

Hepatitis E Emerges as Significant Cause of Liver Inflammation   (Site not responding. Last check: 2007-11-02) Hepatitis E virus (HEV) has emerged as a significant infectious cause of clinical and sub-clinical (silent infection without symptoms) liver inflammation in humans worldwide, particularly in resource-poor nations. He described hepatitis E as an infection transmitted by fecal contamination of water or food, in the same way that hepatitis A virus (HAV) is transmitted. Acute hepatitis E is rare in the US, with most cases occurring among people who became infected in endemic (widespread infection) countries and then returning to the US. www.hivandhepatitis.com /hep_non_aorb/041100.html   (1359 words)

Hepatitis Week -- Your Online Hepatitis Newsletter Hepatitis A, a liver disease caused by hepatitis A virus (HAV), is highly contagious. Hepatitis A vaccine is recommended (before exposure to hepatitis A virus) for persons who are more likely to get hepatitis A virus infection or are more likely to get seriously ill if they do get hepatitis A. Two commercially available and licensed hepatitis A vaccines are Havrix (SmithKline Beecham) and VAQTA (Merck). Hepatitis E (HEV) is spread through food or water contaminated by feces from an infected person. www.hepatitisweek.org /members/All/Hep-ADE-ALL.htm   (942 words)

hepatitis E It is similar to hepatitis A in that it occurs mainly by contamination of food and water. Travelers to areas where hepatitis E occurs may be at some risk of acquiring this disease by close contact with cases or through contaminated food or water. Travelers to these areas should receive IG for protection against hepatitis A, but they should not assume that they are protected against hepatitis E. The best prevention of infection is to avoid potentially contaminated food and water, as with hepatitis A and other enteric infections. www.thirdworldtraveler.com /Disease/hepatitisE.html   (321 words)

Parenting and Child Health - Health Topics - Hepatitis E Pregnant women from countries where there is little hepatitis E are strongly advised not to travel to areas where there is a lot of hepatitis E, especially during the last 3 months of pregnancy. What is hepatitis E? Hepatitis E is an infection of the liver, which is common in many developing countries where there is not a safe water supply, especially South Asian countries and North and East African countries. In countries where hepatitis E is common, it is likely that most young women will have had the infection before becoming pregnant, but in countries where there is little hepatitis E, very few women will have had it before they become pregnant. www.cyh.com /HealthTopics/HealthTopicDetails.aspx?p=114&np=303&id=1540   (910 words)

Hepatitis E - WrongDiagnosis.com Hepatitis E is a hepatitis (acute disease, inflammation of liver) caused by a contagious virus called hepatitis E virus (acronym HEV). With a diagnosis of Hepatitis E, it is also important to consider whether there is an underlying condition causing Hepatitis E. Underlying medical conditions are other medical conditions that may possibly cause Hepatitis E. For general information about Hepatitis E see our basic information pages.

Hepatitis The viruses primarily associated with hepatitis are named in the order of their discovery: A, B, C, D, and E (see Viral Hepatitis Table). Hepatitis E is spread in a similar fashion to hepatitis A and is found primarily in Asia, Africa, and South America. Autoimmune hepatitis is usually a chronic form of hepatitis that frequently leads to progressive damage of the liver; in about 25% of cases, it may present like acute hepatitis. www.labtestsonline.org /understanding/conditions/hep.html   (1200 words)

HEPATITIS Hepatitis A and hepatitis E are mainly transmitted through the fecal-oral route, while hepatitis B, C, and D are spread through blood or other body fluids. An estimated 3% of the world population is chronically infected with hepatitis C virus (HCV), and HCV accounts for approximately 20% of cases of acute hepatitis and 70% of cases of chronic hepatitis.1 Chronic hepatitis C is a major cause of cirrhosis and hepatocellular carcinoma. Co-infection or super-infection with hepatitis D virus in a patient with hepatitis B is diagnosed by the presence of antibodies against the hepatitis D virus. www.biophysica.com /hepatitis.html   (2084 words)

CDC - Yellow Book: [4] Hepatitis, Viral, Type E - CDC Travelers' Health Hepatitis E, which is caused by the hepatitis E virus (HEV), cannot be distinguished reliably from other forms of acute viral hepatitis except by specific serologic testing. Hepatitis E usually occurs in persons who travel to or live in an endemic area. Fulminant hepatitis, however, is more commonly associated with hepatitis E than with other types of viral hepatitis, particularly among pregnant women in the second or third trimester. www2.ncid.cdc.gov /travel/yb/utils/ybGet.asp?section=dis&obj=hev.htm   (747 words)

MD Travel Health - hepatitis E Hepatitis E is a viral infection of the liver that occurs in epidemics as well as sporadically in many countries. However, for unknown reasons, pregnant women who contract hepatitis E are at high risk for developing fulminant hepatitis, resulting in a 15-20% fatality rate. Hepatitis E infection can be diagnosed by measuring antibodies to hepatitis E virus in the blood. www.mdtravelhealth.com /infectious/hepatitis_e.html   (154 words)

Researchers Discover First Animal Strain of Hepatitis E Virus   (Site not responding. Last check: 2007-11-02) Scientists at the National Institute of Allergy and Infectious Diseases (NIAID) in Bethesda, Md., have identified a strain of hepatitis E virus in pigs that is very similar to the strain that causes disease in humans. Hepatitis E virus is most commonly transmitted to people through contaminated drinking water in areas with poor sanitation. "Among most human strains of hepatitis E virus, amino acid identity is between 97 and 99 percent." The researchers say their findings strongly suggest that a previously unrecognized strain of hepatitis E virus circulates in the swine population. www3.niaid.nih.gov /news/newsreleases/1997/hepatitis.htm   (1007 words)

CDC - Viral Hepatitis Hepatitis B: is a serious disease caused by a virus that attacks the liver.
