Hepatitis • Hepatitis A • Hepatitis B • Hepatitis C • Hepatitis D • Hepatitis E • Viruses which attacks the liver • Liver performs many functions vital to life • Blood reservoir, blood filter, carbohydrate, fat, protein metabolism, storage of vitamins, iron, etc.
Hepatitis A • Caused by infection with Hepatitis A virus • NOT BLOODBORNE • Virus is found in the stool of infected persons • HAV is usually spread from person to person by putting something in the mouth (even though it may look clean) that has been contaminated with the stool of a person with hepatitis A • Occurs in epidemics both nationwide and in communities
Hepatitis A--Symptoms • Jaundice • Fatigue • Abdominal pain • Loss of appetite • Nausea • Diarrhea • Fever
Hepatitis A Prevention • Good personal hygiene and proper sanitation can help prevent hepatitis A • Always wash your hands with soap and water after using the bathroom, changing a diaper, and before preparing and eating food • Vaccine is available
Hepatitis B • Caused by infection with Hepatitis B virus • IS BLOODBORNE • Occurs when blood or body fluids from an infected person enters the body of a person who is not immune • HBV is spread through • having sex with an infected person without using a condom (the efficacy of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission) • by sharing drugs, needles, or "works" when "shooting" drugs • from an infected mother to her baby during birth • through needlesticks, sharps exposures, blood splashes on the job, • Can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death
Hepatitis B Symptoms • Jaundice • Fatigue • Abdominal pain • Loss of appetite • Nausea, vomiting • Joint pain
Hepatitis B--Prevention • A safe and effective vaccine is available • Use latex condoms correctly and every time you have sex. (The efficacy of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission.) • If you are pregnant, get a blood test for hepatitis B; Infants born to HBV-infected mothers should be given HBIG (hepatitis B immune globulin) and vaccine within 12 hours after birth. • Never share drugs, needles, syringes, or "works“ • Do not share personal care items that might have blood on them (razors, toothbrushes) • At work, do not come into contact with another person’s blood or body fluids
Hepatitis C • Hepatitis C is a disease of the liver caused by the Hepatitis C virus (HCV) • IS BLOODBORNE • Occurs when blood or body fluids from an infected person enters the body of a person who is not infected • HCV is spread through • having sex with an infected person without using a condom (the efficacy of latex condoms in preventing infection with HBV is unknown, but their proper use may reduce transmission) • by sharing drugs, needles, or "works" when "shooting" drugs, through needlesticks, sharps exposures, blood splashes on the job, or • from an infected mother to her baby during birth • through needlesticks, sharps exposures, blood splashes on the job, • Chronic infection: 55%-85% of infected persons • Chronic liver disease: 70% of chronically infected persons • Leading indication for liver transplant
Hepatitis C--Symptoms • Jaundice • Fatigue • Dark urine • Abdominal pain • Loss of appetite • Nausea • 80% of infected persons have no signs or symptoms
Hepatitis C--Prevention • There is no vaccine to prevent hepatitis C • Do not shoot drugs and never share needles, syringes, or "works" • Do not share personal care items that might have blood on them (razors, toothbrushes) • At work, do not come into contact with another person’s blood or body fluids
Hepatitis D • Hepatitis D is a liver disease caused by the hepatitis D virus (HDV) • It is a defective virus that needs the hepatitis B virus to exist
Hepatitis E • Hepatitis E is a liver disease caused by the hepatitis E virus (HEV) • NOT BLOODBORNE • It is transmitted in much the same way as hepatitis A virus • Hepatitis E does not occur often in the United States

HIV • Human immunodeficiency virus • HIV can be passed from person to person if someone with HIV infection has sex with or shares drug injection needles with another person • It also can be passed from a mother to her baby when she is pregnant, when she delivers the baby, or if she breast-feeds her baby • Leads to disease AIDS • Destroys the immune system
HIV Symptoms • The symptoms are similar to the symptoms of many other illnesses • You might have HIV and still feel perfectly healthy • The only way to know for sure if you are infected or not is to be tested
HIV Prevention • Don’t share needles and syringes used to inject drugs, steroids, vitamins, or for tattooing or body piercing • Don’t share equipment ("works") used to prepare drugs to be injected • Use a latex condom to reduce the risk of STD transmission. • Don’t share razors or toothbrushes because of the possibility of contact with blood • If you are pregnant or think you might be soon, talk to a doctor or your local health department about being tested for HIV. Drug treatments are available to help you and reduce the chance of passing HIV to your baby if you have it • At work, do not come into contact with another person’s blood or body fluids
You Do Not Get Hepatitis B, C, or HIV • By working with or being around someone who has the disease • From sweat, spit, tears, clothes, drinking fountains, phones, toilet seats, or through everyday things like sharing a meal • From insect bites or stings • From donating blood • From a closed-mouth kiss (but there is a very small chance of getting it from open-mouthed or "French" kissing with an infected person because of possible blood contact)
Bloodborne Pathogens (BBPs) • Pathogenic micro-organisms present in human blood that can lead to diseases • Human immuno-deficiency virus (HIV) • Hepatitis B (HBV) • Hepatitis C (HCV)
Other Bloodborne Pathogens • Syphilis • Malaria • Brucellosis • Babeosis • Leptospirosis • Arborviral Infections • Relapsing Fever • Creutzfeld-Jacobs Disease--Mad-cow • Viral Hemorrahgic Fever--Ebola
