Hepatitis C What is hepatitis C? Hepatitis C (formerly called non-A, non-B hepatitis) is a liver disease caused by a recently identified bloodborne virus. Other types of viral hepatitis include hepatitis A (formerly called infectious hepatitis), hepatitis B (serum hepatitis), hepatitis D (delta hepatitis) and hepatitis E (a virus transmitted through the feces of an infected person). Who gets hepatitis C? Hepatitis C occurs most often in people who have received a blood transfusion or who have shared needles. How is the virus spread? Like hepatitis B, hepatitis C is spread by exposure to blood from an infected person, such as through a blood transfusion or sharing needles. The risk of sexual transmission has not been thoroughly studied but appears to be small. There is no evidence that the hepatitis C virus can be transmitted by casual contact, through foods or by coughing or sneezing. What are the symptoms?
Appetite Loss How soon do symptoms occur? Symptoms may occur from two weeks to six months after exposure but usually within two months. When and for how long is a person able to spread hepatitis C? Some people carry the virus in their bloodstream and may remain contagious for years. The disease may occur in the acute form and be followed by recovery or it may become chronic and cause symptoms for years. What is the treatment for hepatitis C? There are no special medicines or antibiotics that can be used to treat people with the acute form of hepatitis C but the FDA has approved a drug called recombinant alpha interferon for treating people with chronic hepatitis C. Is donated blood tested for this virus? Since May 1990, blood donation centers throughout the U.S. have routinely used a blood donor screening test for hepatitis C. Widespread use of this test has significantly reduced the number of post-transfusion hepatitis C cases. What are the possible consequences of hepatitis C? Approximately 25 percent of people infected with hepatitis C virus will become sick with jaundice or other symptoms of hepatitis. Fifty percent of these individuals may go on to develop chronic liver disease. How can the spread of hepatitis C be prevented? People who have had hepatitis C should remain aware that their blood and possibly other body fluids are potentially infective. Care should be taken to avoid blood exposure to others by sharing toothbrushes, razors, needles, etc. In addition, infected people must not donate blood and should inform their dental or medical care providers so that proper precautions can be followed. The risk of sexual transmission of hepatitis C virus has not been thoroughly investigated but appears to be minimal. Several studies suggest that spread seldom occurs from people with chronic hepatitis C disease to their steady sexual partners. Therefore, limitations on sexual activity with steady partners may not be needed. However, people with acute illness and multiple sexual partners may be at greater risk and should use condoms to reduce the risk of acquiring or transmitting hepatitis C as well as other sexually transmitted infections. Is there a vaccine for hepatitis C? At the present time, a hepatitis C vaccine is not available. A safe and effective vaccine for hepatitis B is in widespread use in the U.S. and a new experimental vaccine for hepatitis A is undergoing clinical trials.
