Transcript of Hepatitis B
http://www.hepfi.org Hepatitis B does not affect everyone the same way. Studies show that half of all the people who get Hepatitis B do not have any symptoms at all. For the people who do get symptoms, they usually occur between 30 and 180 days after your body has been exposed to the disease. Many of the symptoms are similar to those of the influenza virus. Some of the symptoms are:
Nausea and vomiting
Itching all over the body
Pain over the liver (right side of abdomen, under lower rib cage)
Jaundice (yellowing of the skin and the whites in the eyes)
Urine turns dark in colour
Solid waste is pale in colour (grayish or clay coloured) That's a bad thing because you need your liver to survive. It is one of your most important organs because it purifies your blood, and provides chemicals that your body needs to stay healthy. Hepatitis B is a disease of the liver. 'Hepa' is Greek for "liver", and 'itis' means "inflamation" in Latin, making hepatitis an inflamation of the liver. An abreviation and more common name for hep B is HBV (Hepatitis B Virus) After having hepatitis for a long time, permanent liver damage can occur. Chronic HBV can also lead to liver cancer. This means that the disease is rarely fatal. When the liver fails the body usually follows shortly after. The liver failing affects almost every part of your body. But remember, the liver rarely fails. Interesting Facts An estimated 400 million people worldwide have chronic hepatitis B. In Canada, 250,000 people have chronic hepatitis, according to the Ontario Service Safety Alliance. Young children (newborns to four years of age) who become infected with HBV are the most likely to develop chronic infection. Death from chronic liver disease occurs in 15–25 percent of people with chronic hepatitis B infection. In the last twenty-five years, the greatest decline in new hepatitis B infections has occurred among children and adults due to routine vaccination. You can contract hepatitis B in many ways, but the most common is through sexual intercourse. Hepatitis B is carried through someone's blood, so you can get it through any type of sexual contact that involves the exchange of bodily fluids. Blood travels in your bodily fluids (i.e. saliva, semen).
You'll know for sure if you have the disease by taking a special blood test. The best way to avoid HBV is to get the vaccine as a preventative measure and a precaution. This vaccine is now being offered to students in grade 7 across the TDSB. You can get HBV more than once in your life-time. Your immune system creates antibodies to fight off the disease and makes you less likely to get it when you're older. There are medications availiable to treat HBV if you get it but the sooner it is caught the better. This way your liver doesn't take as much damage. Several doctors worked on different types of vaccines but it wasn't until the 1980's that a genetically engineered vaccine was created by an American scientist named William Rutter. This vaccine was considered to be safe from contamination and was approved by the U.S. Food and Drug Administration for the use of the general public. Teens should abstain from sexual intercource because it's not worth the risk. When they have intercourse there are so many diseases they can contract, one of them being HBV. If they still have the desire to have intercourse they should be responsible and use appropriate protection. Teens are being pressured by their friends to have sex because they think it's a cool thing to do. But really, it can be dangerous. Most teens act before they think and should ask themselves if they're ready. If they do get a disease will their friends stick around, or ditch them? Now that there is better education in school, students are more aware at a younger age of the consequences. They're able to make better informed decisions. The HBV disease dates back to 2000 BC. It was first written about by a Spanish doctor named Moses Maimonides (1113-1204). Docters knew the disease was contagious but they didn't know how it spread until the 1940's. Sexual intercourse is not the only way to contract the disease. Sharing anything with an infected person's blood on it could be a way of contracting this disease. (for example, drug needles, toothbrushes, razors, body piercing equipment, etc) HBV is 100 times more infectious than HIV HBV can live on a dry surface for at least 7 days.
