Hepatitis Dates

Hepatitis mental institution to Health and sickness April 17, 2010 Hepatitis Introduction Hepatitis is a symptomatic transmission system that affects the coloured. The intimately common types of Hepatitis virus atomic number 18 A, B, C, D and E. The history of hepatitis dates back to ancient propagation and the success of contemporary medicine reach improved the prevention and treatment of tightly types of Hepatitis. The high happen groups include injectible do drugs users, hemodialysis patients, and those who have sexual come by with infect state. Hepatitis B and C atomic number 18 the pencil lead cause of chronic colorful indisposition and liver jackpotcer in the united States.History History of Hepatitis is believed to go back as far as the ancient times. With todays modern medicine scientists have sight a major breakthrough in 1963 that set a serum hepatitis populaten as Hepatitis B computer virus (HBV). Ten course of studys later, they found the c ause of hepatitis infection and cal take it Hepatitis A Virus (HAV). In 1989, Hepatitis C Virus (HCV) was discovered. Hepatitis Delta Virus (HDV) was known in the 1970s, solely was better understood by scientists in the 1980-1990s. Later the Hepatitis E Virus (HEV) was discovered in 1990. EtiologyHepatitis A (HAV) the to the lowest degree serious form and may start out as an isolated case of an epidemic. It is estimated that oneness out of every 3 peck has been affected by HAV. Transmission of HAV is associated with close individualal opposition or contaminated food or water (Wilson, p. 13). Hepatitis B (HBV) is transmitted primarily by speck with septic blood, semen, and other bodily fluids. injectable drug users, people with multiple sexual partners and homosexuals atomic number 18 at higher gamble for contracting the B virus. Hepatitis B can severely damage a persons liver, provideing in pubic louse (Nordqvist, 2009).Hepatitis C (HCV) is the most serious blood borne infection in the United States. The disease is much passed between drug users who shargon needles. mickle who are on dialysis and sexual get hold of are also at risk. The hepatitis virus is the leading cause of liver pubic louse and the most common drive for liver transplants (Wilson, 2005). Hepatitis D (HDV) is a defective virus that only if the people who are infected with Hepatitis B. The virus is transmitted through contact with infected blood, unprotected sex, and piercing of the jumble with infected needles.The effects of HDV are more than serious and emanationes to chronic liver disease more frequently than virus A, B, or C. Hepatitis E (HEV) is the leading cause of epidemics nigh the world, but cases in the United States are rare. Primarily HEV is spread by faecal contaminated drinking water and thither is no evidence that HEV progresses to chronic liver disease (Wilson, 2005). on that point have been no cases of HEV reported in the United States. Patients with H epatitis A and B typically experience abrupt unset of fever, malaise and fatigue, nausea and abdominal pain. Anorexia and bitter may also be present.Hepatitis C is less forgiving as symptoms may non appear until the patients condition has progressed to cirrhosis or cancer (Neighbors & Tannehill-Jones, 2006). Populations affected by Hepatitis In the United States near 1. 2 million are spirit with Hepatitis B and 3. 2 are existing with Hepatitis C. Estimated 25,000 people become infected with Hepatitis A. approximately people do non know the virus infection survive in the body (CDC, 2009). The Center for Disease Control (2009) estimates 180 million people over the world is infected with HCV, of which four million are identified as cases in the United States.Each year 26,000 cases of HCV are diagnosed in the United States alone, and 10,000 to 12,000 deaths are contributed to HVC (Centers for Disease Control CDC, 2009, p. 1). The hepatitis virus is the leading cause of liver cancer and the reason for liver transplants. In the United States approximately 1. 2 million are living with Hepatitis B and 3. 2 are living with Hepatitis C. Estimated 25,000 people become infected with Hepatitis A. Many people do not know the virus infection exist in the body (CDC, 2009). intercessionIn July of 1982 the Hepatitis B vaccine was approve for use and long dozen years later (1995) the HAV vaccine was approved for use. These significant scientific breakthroughs have led a steady decline in the number of HAV and HBV cases in the United States. thither is not a vaccine ready(prenominal) for HCV but scientists are working ticklish to develop one. In addition to the vaccines some treatment options are available. HAV usually resolves itself and no specific treatment is needed. Treatment for HBV is Interferon which slows the progress of the disease in slightly 40% of patients (Neighbors & Tannehill-Jones, 2006).In addition to treating HBV Interferon is very powerful fo r treating HCV. This antiviral slows the disease process about 30% of the time (Neighbors & Tannehill-Jones, 2006). There is not an effective treatment for HDV or HEV. Treatment for end stage cirrhosis or cancer caused by hepatitis may result in a liver transplant. proof Hepatitis is a disease that causes an inflammation of the liver. There are several viruses that cause cirrhosis or cancer of the liver. Hepatitis A is a mild disease that typically resolves itself.The hepatitis B virus is more severe than A and less severe than C. The availability of vaccines for Hepatitis A and B has decreased the number of cases season Hepatitis C continues to infect high risk populations. Scientists continue to strive for a resume for Hepatitis C but in the meantime a people need to be aware of the disease and take step the reduce the possibility of exposure.
