Hepatitis is a disease that is slowly making itself known throughout the world. We don't hear about it often, but it's a disease that we actually know nothing or very little about. Hepatitis is a disease that attacks the liver, causes the liver to become inflamed. The cause of the disease is caused by toxins in the body or toxins that we put into our body, namely alcohol. It can also be caused by other viruses that cause liver damage, such as hepatitis A and hepatitis C. Hepatitis A is caused by not washing your hands first and can also be contracted by eating contaminated food from someone who is not it is washed. your hands before preparing food. It is a serious disease that can be truly dangerous and it doesn't take much to stop its spread. Hepatitis is a disease that attacks the liver and it is estimated that around 350 million people worldwide have been infected with the disease and by having so many people infected it causes 620,000 deaths per year worldwide. According to the Centers for Disease Control (CDC), approximately 43,000 people were infected with HBV in the United States in 2007. In the United States, people who contract this disease are people between the ages of 25 and 44, and it is the youngest if 15 years old. We have so many people infected at that age because it can be transmitted through sexual intercourse and at that age they are usually very sexually active, or using illicit drugs and are probably exposed to contaminated blood. Since 1990 there has been a decline in infected people or children due to vaccinations and also increased public awareness of the disease. When a person contracts hepatitis B they are considered to have an "acute" infection. Most people can be cured with help... middle of paper... can be easily diagnosed. Abnormalities in the blood can also help in diagnosing the disease. There is only one way to make sure it is hepatitis and these tests are known as markers or serology. Markers in the blood can confirm hepatitis B and also detect whether it is acute hepatitis. These markers are substances produced by the hepatitis B virus and antibodies produced by the immune system to fight the virus. It has 3 antigens for which there are commonly used tests. For acute hepatitis B, no drugs are needed in some cases, although patients may be diagnosed with liver failure. If a person is diagnosed with a chronic disease, he or she needs to undergo several blood tests so that he or she can receive the right treatment. If the patient is diagnosed with hepatitis B antigen, he will be given a different type of drug as this leads to liver failure
