Hepatitis B Research Paper

Hepatitis B is a disease that basically attacks the liver. Hepatitis B is a transmitted disease, meaning you can't get hepatitis B unless a persons bodily fluids has been transmitted from one person to another who isn't affected. You can get hepatitis B by also doing common things that doesn't seem like not a big deal, but leads to a big effect later on. For example, you can get hepatitis B by using another person's razor because if you cut yourself with it and they cut themselves with it as well it could lead to infection and easily into your body. Also by sharing dirty needles and being tattooed and that's's why it is very important to make sure everything is completely sanitized no matter what it is. Depending how badly it is you could cause

This can also increase the risk of liver cancer. Approximately 90-95% of adults will recover within six months and not contact HBV again.(2) However, blood tests will always show that the person was infected with HBV and blood banks will not accept their blood. About 5-10% of adults and 25-90% of children under the age of 5 that are infected with HBV are not able to get rid of the virus after 6 months. These people are considered to be chronically infected, commonly called Hepatitis B carriers. The carrier rate of Hepatitis B varies throughout the world, being uncommon amongst westerners, but reaching as high as 20% in people from Asia and Africa. With the immigration of foreigners into new countries, Hepatitis B is now becoming established in parts of countries where it previously was not.

Green monkey kidney cells were used to grow and research viruses for vaccine. The first trials of OPV took place in the belgian congo which is now the Democratic Republic of Congo from 1957-1960.

So what is Hepatitis B and what causes it? This is a liver disease that is normally spread through person to person via contact with the following: blood, semen, body fluids from a person with the virus. Most commonly, this disease unfortunately is spread from the mother to her

A) Each of the injections is specifically formulated to protect against Hepatitis A, B, or C.

No antibacterial compounds are available resistant to this disease but genetic engineering has developed the first trees to resist this devastating disease and increased the consumption level. Specific foods have been developed to correct malnutrition problems. To this end, plants have been modified to provide increased and more stable quantities of essential amino acids, vitamins, or desirable fatty acids. For example, golden rice has been genetically modified to increase beta-carotene content which may help to overcome the severe vitamin A deficiencies that cause blindness and iron. Plants can also be genetically modified to grow well in areas of low production potential. For example, two researchers in Mexico inserted a gene from a bacterium into papaya and tobacco to produce acid-tolerant crops. The crops thus secrete citric acid from their roots by combining with toxic metals which in turn making the soils accessible to protect the tropical forests which contain most of the world’s species of plants and animals. Genetic engineering also helps to decrease or eliminate the allergenic proteins that occur naturally. For example, it has been already used to reduce the levels of major allergen in rice and peanuts. Genetic engineering brings closer the prospect of commercial production in plants of edible vaccines and therapeutics for preventing and treating human diseases like cancer and diabetes. The genetically derived vaccines are potentially

Treatment is varied. There are several drugs used to treat hepatitis in the United States. Intron A, Epivir-HBV, Pegasys, Baraclude, Hepsera, Viread, and Tyzeka are the only FDA approved drugs that have been shown to slow the virus and decrease liver damage and in some cases the virus is killed completely ("Hepatitis Treatments," n.d.). Ultimately vaccination is the best way to prevent HBV. The vaccine has been found to be effective and safe. Administration is given over a 6 month time and consists of 3-4 shots ("Hepatitis B," n.d.) and is estimated to be 95% effective. Everyone should be vaccinated but the

The severity of complication range from mild discomforts to death. According to the CDC, 2014 “approximately 15%–25% of people with chronic Hepatitis B develop serious liver problems, including liver damage, cirrhosis, liver failure, and liver cancer”. It is estimated that nearly one million people in the United States (US) have chronic HBV and approximately 3,000 people die yearly from HBV liver related problems. Since the introduction of the immunization in 1990 there has been more than a 80% reduction in the number of HBV cases here in the US. Globally, approximately 350 million people are estimated to have chronic HBV and there are an estimated 620,000 contributory

One such deadly disease is Hepatitis B. Hepatitis B is a life threatening liver infection that is caused due to Hepatitis B virus. This virus leads to chronic infection and results in to high risk of cirrhosis and liver cancer. Hepatitis B has two types, which have different effect on adults. Acute Hepatitis B occurs for short time. People usually affected by acute virus, get well with the time. On the other hand, there is Chronic Hepatitis B, which causes long time infection and damages liver. This virus spreads through the blood and body fluids of an infected person.

This Paper was written as an informative project about the Hepatitis B virus. The paper was written in a way that clearly discusses the specific causes, symptoms, treatments and prevention associated with the virus. The paper goes into details on ways to avoid contraction of this virus as well.

Hepatitis B virus was discovered by the man Dr. Baruch S. Blumberg, a Nobel Prize winning biochemist, in 1963 with the help of some of his colleagues and later help discover a helpful vaccine to fight the harmful virus (nytimes). Blumberg looked into studying the inherited traits to see if it could make more or less people to get the Hepatitis B virus (CEVHAP). Hepatitis B can be spread without the person knowing by open wound and can survive at least a week outside its host. Hepatitis is the 10th leading cause of death in the past few years. The virus is found throughout the world and it will continue to spread rapidly.

Hepatitis B is transmitted 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; sharing needles, syringes, or other drug-injection equipment, or even from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. In addition, some people, especially adults, are able to clear, or get rid of the virus without treatment. People who clear the virus become immune and cannot get infected with the Hepatitis B virus

Individuals with inactive hepatitis B surface antigen are referred to as chronic carriers. These individuals may not show clinical signs of the disease. They do not exhibit raised levels of AST and ALT, but they tend to have low viral loads (Zein & Edwards, 2009). Individuals with HBeAg positive or negative tend to exhibit higher viral loads and they are both contagious (Zein & Edwards, 2009). Individuals who are HBeAg negative do not have the antigen themselves, but are still able to spread the disease to others. Individuals who have resolved chronic hepatitis B are less likely to develop liver cancer or cirrhosis and their AST, ALT, and

The symptoms start appearing after two to five weeks of infection. The main symptoms are nausea, vomiting, diarrhea, low fever, rashes, loss of appetite and yellowing of skin (jaundice), abdominal pain. Diarrhea occurs in case of children. No specific treatment is there. Patients need adequate rest and proper nutrition. If skin becomes yellow then the patient needs a blood test or a liver panel test. If a person vomits for a long period amount of time, they get dehydrated; then, only then, hospitalization is needed. Patients should drink a plenty amount of water, or fluids. He or she should take food, which does not cause any harm to the liver. Patients should avoid tea, coffee or any alcoholic beverages, which causes harm to liver. He or she takes adequate rest. He should not take any medicine which causes harm to liver. If patient is confused about taking medicine then he or she should consult a doctor. Techniques for growing HAV in cell culture have made it possible to generate sufficient amounts of virus for vaccine production. Several inactivated or live attenuated vaccines against hepatitis A have been developed, but only four inactivated hepatitis A vaccines are currently available internationally. All four vaccines are similar in terms of efficacy and side-effect profile. The vaccines are given parenterally, as a two-dose series, 6-18 months apart. The dose of vaccine,

In less wealthy countries, kids stand in line for hours to get shots that treat infectious diseases that have the potential to kill. But what if the kids could eat dinner and be safe from those diseases for years after they ate a meal? Anti-cholera potatoes are genetically modified potatoes that contain the fluids that prevent cholera. Sometime in the future, there is a possibility that shots and treatments will be a thing the past. All you will have to do is eat a potato, and for the rest of your life, you wont have to worry about getting cholera. There are some drawbacks in this though. For example, when the plants spread pollen, the pollen will carry the gene the gene that makes the food medicated. If the pollen spreads, the gene will spread causing the natural potatoes to become medicated. This could cause people who didn’t want the medicine to take it without realizing it.
