Viral Hepatitis
•Can lead to cirrhosis (destruction) of the liver and subsequent liver cancer
•Leading cause of liver cancer globally
•#1 reason for liver transplantation
•4.4 million Americans are living with chronic hepatitis
•Most don’t know they are infected
•80,000 new infections occur each year

Viral Hepatitis
•5 types:
•Hepatitis A
•Transmitted via fecal oral route
•Hepatitis B
•Sexually Transmitted and through blood to blood contact
•Hepatitis C
•Transmitted through blood to blood contact
•Hepatitis D
•Transmitted through percutaneous or mucosal contact with infected
blood, Hepatitis B must also be present, uncommon in US
•Hepatitis E
•Transmitted via fecal oral route, uncommon in the US
•Hepatitis A, B and C are the most common
•This presentation will focus on Hepatitis B and C
Hepatitis B
•Hepatitis B Virus (HBV) is transmitted through:
•Unprotected sexual contact with an infected individual
•Sharing needles or “works”
•Mother to child during birth
•Blood to blood contact
•Sharing razors or toothbrushes with an infected person
•HBV can live outside of the body for up to 7 days
Hepatitis B
•Signs and Symptoms of HBV include:
•Fever
•Fatigue
•Loss of appetite
•Nausea
•Vomiting
•Abdominal Pain
•Dark Urine
•Clay-colored stool
•Jaundice
•Pain in the joints
•Symptoms can last from several weeks to 6 months
•The test for HBV is a blood test
Hepatitis B
•HBV can become a chronic infection
•90% of infants who are infected will become chronic
•25%-50% of children aged 1-5 years will become chronic if infected
•5% of adults will become chronic if infected
•HBV accounts for up to 4,000 deaths in the US per year:
•25% of children who become chronically infected will die prematurely
•15% of adults who become chronically infected will die prematurely
Hepatitis B
•Prevention:
•Get vaccinated
•Recommended for all infants at birth and all individuals who have
never been vaccinated
•Immunity lasts for at least 20 years
•Is given in 3 doses
•Properly and consistently using condoms during sex
•Not sharing needles or rinse water
•Not sharing razors or toothbrushes with an infected person
•Using gloves and other protective wear when handling blood or blood
products
Hepatitis C
•Hepatitis C Virus (HCV) is transmitted through:
•Injection Drug Use-sharing needles
•Receiving blood or blood products in the US before 1992
•Infected mother to child transmission
•Unprotected sex with an infected person (uncommon)
Hepatitis C
•Symptoms:
•Fever
•Fatigue
•Dark urine
•Clay-colored Stool
•Abdominal Pain
•Loss of Appetite
•Nausea
•Vomiting
•Pain in the joints
•Jaundice

•HCV infection can be confirmed by a blood test
Hepatitis C
•1 of every 3 injection drug users is estimated to be infected with HCV
•The CDC estimates that 17,000 people become acutely infected with HCV
annually in the US
•75%-85% of individuals who get Hepatitis C will subsequently develop a
chronic infection
•Approximately 3.2 million people in the US have a chronic Hepatitis C infection
•Of every 100 people that become infected with HCV
•75-85 will develop a chronic infection
•60-70 will develop chronic liver disease
•5-20 will develop cirrhosis over a 20-30 year span
•1-5 will die as a consequence of the virus (liver cancer or cirrhosis)
Hepatitis C
•Treatment for HCV:
•15%-25% of individuals with an acute HCV infection will naturally clear it
out of their body
•It is very difficult to “cure” chronic HCV infection and therapy is not always
successful at managing the infection
•“Cure” corresponds to a sustained virologic response in which viral
loads are undetectable after treatment and the individual is no longer
infectious
•Combination Therapy
•Ribavirin and pegylated interferon
•All individuals with chronic hepatitis C infection should be vaccinated for
Hepatitis A and Hepatitis B to prevent further damage to the liver
Hepatitis C
•Prevention:
•There is NO VACCINATION for Hepatitis C
•Do not share needles or rinse water
•Wear protective equipment when handling blood or blood products
•Do not engage in unprotected sexual contact with an infected person
