Laying Down A Framework

Hep 101

Today We Will•Define hepatitis, viral hepatitis & the liver

•Learn about the 5 different types of viral hepatitis

•Learn more about hepatitis C:–The scope of the disease–Signs/symptoms –Risk factors and prevention

What Is Hepatitis?• Hepatitis means inflammation of the liver

– Hepat (liver) + itis (inflammation)= Hepatitis• Viral hepatitis means there is a specific virus that is causing your liver to inflame (swell or become larger than normal)

The Liver• Is located in the upper right quadrant of the abdomen

•Cleans the blood•Regulates hormones•Helps with blood clotting•Produces bile•Produces important proteins•Maintains blood sugar levels•And much, much, more

• The liver is essential for life !

Inflammation

Walls of scar tissue begin to form Healthy liver

cells become trapped by a wall of scar tissue

Viral Hepatitis5 types:A: fecal-oral transmissionB: sexual fluids & blood to blood C: blood to bloodD: travels with BE: fecal–oral transmission

VaccinePreventable

Adapted from Corneil, 2003

Hepatitis C Infection• World - 170 million people • Canada - 240,000 to 300,000 (0.8% to 1% of pop.)• BC - 40,000 (1%)• Vancouver - 11,350 (2%)• DTES VIDUS Study - 1,437•90% hep C posititve

WHO 2000, BC Hepatitis Service 2003, VIDUS 2003

Hepatitis C•Affects each person differently

•No vaccine available•Many people have the virus and do not even know it

Factors Affecting Progression

• 30yrs or longer if:•Young at time of infection•Healthy liver at time of infection•Female

• 20yrs or less if:•Drinking alcohol•Co-infection (HIV, Hep B)•Damaged liver before infection
