A Short Note On Hepatitis And The Virus

12- Hepatitis A- is usually not a serious illness. It is prevalent in developing countries, especially those with overcrowding and poor sanitation, in men who have sex with men, and injecting drug users.

HBV, as stated above, is a disease that affects the liver by coming into contact as an infant from the mother during birth, sex with an infected partner, sharing needles, razors, or toothbrushes of an

Hepatitis C contamination additionally expands the danger of creating liver disease just like hepatitis B. Until the 1980 's, hepatitis C virus (HCV) was known as non-A non-B hepatitis. The underlying disease may have side effects, yet a critical number of individuals don 't have side effects. Not at all like hepatitis B, in which the ailment does not frequently get to be constant, have around 80% of individuals with hepatitis C built up an endless disease. As the invulnerable framework keeps on assaulting the infection after some time, fibrosis grows, in the end prompting cirrhosis. This unending aggravation can likewise prompt liver growth. This infection is spread through tainted blood, for example, with transfusions and IV drug misuse, however numerous individuals don 't have evident danger components for the sickness. It is currently suggested that

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 A is a liver infection caused by the Hepatitis A virus (HAV). Hepatitis A is highly contagious. It is usually transmitted by the fecal-oral route, either by person-to-person contact or consumption of contaminated food or water. Moreover, Hepatitis A is a self-limited disease that does not result in chronic infection. More than 80% of adults with Hepatitis A have symptoms but the majority of children does not have symptoms or have an

See a doctor right away if you or a child in your care has symptoms of hepatitis A.

Hepatitis A is a viral infection of the liver. The virus causes inflammation in your liver and is contagious. Most cases of hepatitis A are fairly mild and people recover fully.

It is estimated that hepatitis B infects approximately one third of the world population— mostly young adults and teenagers. Of that percentage, about 340 million people are chronically infected meaning they cannot get rid of the virus. Sadly, this statistic leads to the depressing rate of approximately one million hepatitis B related deaths each year (Nguyen, V. T., & Dore, G. J., 2008).

Hepatitis A virus, HAV is a nonenveloped, RNA virus. The virus is resistant to bile lysis due to lack of a lipid envelope. The virus is resistant to freezing, detergents, and acids. It is inactivated by formalin and chlorine. The virus survives on human hands and fomites and requires temperatures higher than 185°F (85°C) for inactivation. HAV survives for extended periods in seawater, fresh water, wastewater, and soil. The virus is transmitted by close contact with an infected person or by contact with contaminated food or water products.”

In the 1960’s and 70’s the virus was actually identified after years of research. Scientists were able to discover the Hepatitis A and Hepatitis B virus through numerous blood tests. They also noticed there were patients that tested positive for a virus that was not Hepatitis A or B. This unknown virus was named non-A, non- B hepatitis. In the 1980’s, The Center for Disease Control was able to identify the virus where it was given the name Hepatitis C (“Hepatitis C FAQ”). In 1990, blood banks started testing for the virus by screening blood before it was transfused. By screening the blood, this reduced the risk of contraction by .01% (“Hepatitis C History”). There are two types of Hepatitis C known as Acute Hepatitis C and Chronic Hepatitis C. Acute hepatitis C is a short-term infection in which symptoms can last up to 6 months. Those with Acute Hepatitis C endure the short term effects of the infection because the body is able to fight off the infection and get rid of the virus. In most cases, the infection is asymptomatic but can lead to a more serious infection which can lead to scarring of the liver causing cirrhosis. This form of HCV is known as Chronic Hepatitis C in which the infection causes cirrhosis of the liver. Cirrhosis can take many years, but it can lead to other health concerns such as liver failure, liver cancer, and other life threatening issues. Patients that contract cirrhosis of the

Medicine is one of our most powerful assets as human-beings, it allows us to extend the life expectancy and resist disease and infection that we would not have been able to in the past. Even though there were many advancements in medicines there are still very powerful diseases such cancer, diabetes, STDs, epidemic diseases, and the forms of hepatitis. A recent breakthrough may have led to the discovery of the cure for hepatitis-C. This is very important for society in multiple forms and I believe with this discovery we as a society may be able to destroy this form of hepatitis and development new opportunities in other parts of the medical field.

It could be transmitted through blood and infected bodily fluid, such as saliva, menstrual, vaginal, and seminal fluids. It can be from direct blood-to-blood contact like when an individual get a blood transfusion from an infected individual. These cases were more popular in the past years when doctors did not test blood samples for viruses before a blood transfusion. Hepatitis B also can be transmitted from unprotected sex. Transmission of this virus may also occur when needles and syringes, either in healthcare settings or among people who inject drugs, are reused. Getting a tattoo can also be a risk of getting Hepatitis B. In highly endemic areas, hepatitis B is commonly spread from mother to child at birth. Once an infant is infected with the virus, it is easy for it to spread it to other uninfected children. The Hepatitis B virus can survive outside the body for at least 7 days. During this period, the virus can still infect people who do not have the

Hepatitis B was first founded in 1966 by Baruch S. Blumberg. It was first discovered when Dr. Blumberg and his team traveled around the world collecting blood samples from the native population in remote parts of the world. Dr. Blumberg and his team had planned to look for genetic differences and study whether or not the differences were caused or associated with diseases. Technology wasn’t that far progressed though so they had to reevaluate their plan so they decided to turn their attention to the hemophiliac patients. Dr. Blumberg believed that hemophiliacs who received multiple blood transfusions would have been exposed to blood serum proteins that they did not inherit themselves but had been inherited by their

Hepatitis is caused by a virus that is targeted at the liver, one of your most important organs!! Specifically, it causes inflammation and injury to the liver. Hepatitis comes in many different forms, five to be exact. There is Hepatitis A, B, C, D & E. Hepatitis is caused mainly by viruses, all of which are set on shutting down your liver. I will be specifically concentrating on Hepatitis A in this report. Hepatitis A is also known as infectious Hepatitis, an extremely contagious viral infection that often effects young children and young adults, especially those in large groups. It has been known to break out in schools, summer camps and music festivals etc.

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,
