What is hepatitis B?
Hepatitis B (formerly known as serum hepatitis) is a liver disease caused by a virus. The disease is fairly common; more than 2,000 cases are reported in New York State each year.
Who gets hepatitis B?
Anyone can get hepatitis B, but those at greater risk include:
drug abusers who share needles;
certain health care workers who have contact with infected blood;
homosexual males, particularly those with multiple partners;
people in custodial care (in settings such as developmental centers);
hemodialysis patients;
certain household contacts of an infected person;
infants born to mothers who are hepatitis B carriers.
How is the virus spread?
Hepatitis B virus can be found in the blood and, to a lesser extent, saliva, semen and other body fluids of an infected person. It is spread by direct contact with infected body fluids; usually by needle stick injury or sexual contact. Hepatitis B virus is not spread by casual contact.
What are the symptoms of hepatitis B?
The symptoms of hepatitis B include fatigue, poor appetite, fever, vomiting and occasionally joint pain, hives or rash. Urine may become darker in color, and then jaundice (a yellowing of the skin and whites of the eyes) may appear. Some individuals may experience few or no symptoms.
How soon do symptoms appear?
The symptoms may appear two to six months after exposure, but usually within three months.
For how long is a person able to spread the virus?
The virus can be found in blood and other body fluids several weeks before symptoms appear and generally persists for several months afterward. Approximately 10 percent of infected people may become long-term carriers of the virus.
What is the treatment for hepatitis B?
There are no special medicines or antibiotics that can be used to treat a person once the symptoms appear. Generally, bed rest is all that is needed.
What precautions should hepatitis B carriers take?
Hepatitis B carriers should follow standard hygienic practices to ensure that close contacts are not directly contaminated by his or her blood or other body fluids. Carriers must not share razors, toothbrushes or any other object that may become contaminated with blood. In addition, susceptible household members, particularly sexual partners, should be immunized with hepatitis B vaccine. It is important for carriers to inform their dentist and health care providers.
How can hepatitis B be prevented?
A vaccine to prevent hepatitis B has been available for several years. It is safe, effective and is recommended for people in high-risk settings who have already been infected and infants who are born to mothers who are carrying the virus. It is also recommended that hepatitis B vaccine be universally administered to all children along with their routine childhood immunizations beginning at birth or two months age. A special hepatitis B immune globulin is also available for people who are exposed to the virus. In the event of exposure to hepatitis B, consult a doctor or the local health department.
Hepatitis C (serum hepatitis)
What is hepatitis C?
Hepatitis C (formerly called non-A, non-B hepatitis) is a liver disease caused by a recently identified blood borne 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). Approximately 200 cases of hepatitis C are reported in New York State each year.
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?
Some people experience appetite loss, fatigue, nausea and vomiting, vague stomach pain and jaundice (a yellowing of the skin and whites of the eyes).
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.
