HCV is the leading etiological agent for chronic hepatitis, hepatocellular carcinoma, and liver cirrhosis Drexler, et alp. Contamination with infected blood is the leading mode by which the disease is spread to healthy individuals. Sharing of needles or other equipment used by intravenous drug users also is known to be a way of transmitting the disease.
More Essay Examples on Disease Rubric It is usually asymptomatic, especially in young children, but when symptoms occur they include abdominal pain, loss of appetite, nausea, fever, and general weakness.
It never lasts longer than six months, and so it does not cause cirrhosis. There is no treatment that Research paper hep c shorten the course of the disease, and dehydration is the most common cause of hospitalization.
The average mortality rate is around. It is much higher in adults over 40, and much lower in young children. There arecases in the U. S each year, and there are over 1, worldwide, even though there is an effective vaccine available Achord.
Three hundred fifty million people in the world are infected with Hepatitis B HBVand nearly one million die from it each year. Now, transmission is usually caused by sexual contact, sharing razors or toothbrushes, and drug related activity Achord.
Transmission from household contact is rare, but possible since the virus can survive outside the body for several days, even on a dry surface Kennamer. Usually treatment just involves treating the symptoms, which are similar to HAV.
Chronic HBV leads to scarring of the liver, which usually takes about 20 years to become severe enough to be classified as cirrhosis.
Liver transplants have good long term results for these people. These people can pass the disease on to others, and may not know they are infected since they have no symptoms Achord. The HBV vaccine is helping bring down the number of new infections, and is recommended to anyone who is exposed to blood, or blood containing fluids on a regular basis Kennamer.
Hepatitis C HCV is one of the most common chronic diseases in the world. With no vaccine to help prevent the spread, there are more than four million people infected in the U. It is only blood borne, like HBV, and since it is not easily transmitted sexually or through household contact, the testing of donated blood has reduced the rate of new infections tenfold.
It is usually asymptomatic, but if symptoms present, they are flu-like. Because the symptoms are so mild, it often goes unnoticed until it is advanced, and has caused serious liver damage Achord. Any use of alcohol, even moderate, increases your risk of cirrhosis tenfold.
Interferon can be used in the acute phase of HCV, unlike in HBV, because it does not have the week worsening phase.
It is rare in the U. It is more likely to be chronic than in any of the other Hepatitis viruses, and also is the most likely to cause acute liver failure Achord. It is highly infectious, and there is no vaccine. Unlike the other hepatitis viruses it has a high mortality rate in pregnant women and their fetuses, but mortality is low among men and women who are not pregnant.
There have not been any cases of HEV in the U. HGV is common, and is usually transmitted through blood transfusions or plasma. Because it is considered to be inconsequential, donated blood is not tested for HGV Achord.
Research is currently being done to find cures for chronic hepatitis sufferers, and for finding a vaccine for HCV. Until then, new infections of every type are on the decline due to education about the dangers of blood borne diseases.
Information about AIDS specifically has helped reduce the spread of the blood borne viruses. Tattoo and body piercing shops that re-use needles are still being blamed for some new cases, so anyone interested in visiting such a place should make sure they are a reputable shop that uses disposable needles Achord.
To help prevent the spread of fecal borne varieties, people who come in contact with feces should practice proper hand washing at all times Kennamer.
