Health experts estimate that about 400 million people are infected with hepatitis. Viral hepatitis infections kill nearly one million people a year. The majority of cases are in Asia and in African countries south of the Sahara. A vaccine and treatment for some forms of hepatitis are now available. But they can be costly. The World Health Organization says the high cost of drugs is one big problem in fighting hepatitis. Another problem is that most people living with hepatitis do not know they are infected. There are five different hepatitis viruses: A, B, C, D and E. All five cause inflammation of the liver. The organ can become large and painful. Hepatitis A and E are spread through infectious waste in food or water. These forms of the disease cause acute infection. However, most people recover. The best way to prevent Hepatitis A is by getting a vaccination. But the U.S. Food and Drug Administration has yet to approve a vaccine for Hepatitis E. It is usually found in countries with polluted water supplies and poor waste treatment systems. Hepatitis B and Hepatitis C can be the most serious. These two viruses are responsible for 80 percent of all liver cancer deaths. You can get Hepatitis B from sexual contact or by sharing needles and syringes. They are used to inject drugs. Hepatitis B is common worldwide. The best way to prevent Hepatitis B is by getting vaccinated. Hepatitis C is spread mainly through sharing drug needles and syringes. There is no vaccine for Hepatitis C.
