1 Bloodborne Pathogens

2 TOSHA believes the information in this presentation to be accurate and delivers this presentation as a community service. As such, it is an academic presentation which cannot apply to every specific fact or situation; nor is it a substitute for any provisions of 29 CFR Part 1910 and/or Part 1926 of the Occupational Safety and Health Standards as adopted by the Tennessee Department of Labor and Workforce Development or of the Occupational Safety and Health Rules of the Tennessee Department of Labor and Workforce Development.

3 Bloodborne Pathogens 4 Pathogenic micro- organisms present in human blood that can lead to diseases 4 Most common in US –Human immuno- deficiency virus (HIV) –Hepatitis B (HBV) –Hepatitis C (HCV)

4 Hepatitis 4 Hepatitis A 4 Hepatitis B 4 Hepatitis C 4 Hepatitis D 4 Hepatitis E 4 Viruses which attacks the liver 4 Liver performs many functions vital to life –Blood reservoir, blood filter, carbohydrate, fat, protein metabolism, storage of vitamins, iron, etc.

5 Hepatitis A 4 Caused by infection with Hepatitis A virus (HAV) 4 Virus is found in the stool of infected persons 4 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 4 Hepatitis A infection occurs in epidemics both nationwide and in communities 4 Hepatitis A is NOT bloodborne and, therefore, is NOT covered by the bloodborne pathogen standard

6 Hepatitis A--Symptoms 4 Jaundice 4 Fatigue 4 Abdominal pain 4 Loss of appetite 4 Nausea 4 Diarrhea 4 Fever

7 Hepatitis A Prevention 4 Good personal hygiene and proper sanitation can help prevent infection with the hepatitis A virus 4 Always wash your hands with soap and water after using the bathroom, changing a diaper, and before preparing and eating food 4 Vaccine is available

8 Hepatitis B 4 Hepatitis B is a disease of the liver caused by infection with the hepatitis B virus (HBV) 4 Infection occurs when blood or body fluids from an infected person enters the body of a person who is not immune 4 HBV is spread through: –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) –Sharing drugs, needles, or "works" when "shooting" drugs –Exposure to blood and body fluids on the job –From an infected mother to her baby during birth

9 Hepatitis B 4 HBV can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death 4 Symptoms –Jaundice –Fatigue –Abdominal pain –Loss of appetite –Nausea, vomiting –Joint pain

10 Hepatitis B--Prevention 4 A safe and effective vaccine is available 4 Use latex condoms correctly and every time you have sex 4 If you are pregnant, get a blood test for hepatitis B 4 Never share drugs, needles, syringes, or "works 4 Do not share personal care items that might have blood on them (razors, toothbrushes) 4 Do not come into contact with another persons blood or body fluids at work

11 Hepatitis C 4 Hepatitis C is a disease of the liver caused by infection with the hepatitis C virus (HCV) 4 Infection occurs when blood or body fluids from an infected person enters the body of a person who is not infected 4 HCV is spread through –Sharing needles or "works" when "shooting" drugs, –Exposure to blood and body fluids on the job –From an infected mother to her baby during birth 4 55%-85% of infected persons are chronically infected 4 70% of chronically infected persons develop chronic liver disease

12 Hepatitis C 4 Hepatitis C infection is the leading indication for liver transplant 4 Symptoms –Jaundice –Fatigue –Dark urine –Abdominal pain –Loss of appetite –Nausea 4 80% of infected persons have no signs or symptoms

13 Hepatitis C--Prevention 4 There is no vaccine to prevent hepatitis C 4 Do not shoot drugs and never share needles, syringes, or "works" 4 Do not share personal care items that might have blood on them (razors, toothbrushes) 4 Do not come into contact with another persons blood or body fluids at work

14 Hepatitis D 4 Hepatitis D is a liver disease caused by infection with the hepatitis D virus (HDV) 4 It is a defective virus that needs the hepatitis B virus to exist

15 Hepatitis E 4 Hepatitis E is a liver disease caused infection with the hepatitis E virus (HEV) 4 It is transmitted in much the same way as hepatitis A virus through the fecal/oral route 4 Hepatitis E virus is NOT bloodborne and is NOT covered by the bloodborne pathogen standard 4 Hepatitis E virus does not occur often in the United States

16 Viral Hepatitis - Overview A A B B C C D D E E Source of virus feces blood/ blood-derived body fluids blood/ blood-derived body fluids blood/ blood-derived body fluids feces Route of transmission fecal-oralpercutaneous permucosal percutaneous permucosal percutaneous permucosal fecal-oral Chronic infection no yes no Prevention pre/post- exposure immunization pre/post- exposure immunization blood donor screening; risk behavior modification pre/post- exposure immunization; risk behavior modification ensure safe drinking water Type of Hepatitis

17 HIV 4 Human immunodeficiency virus 4 Infection occurs when blood or body fluids from an infected person enters the body of a person who is not infected 4 HIV is spread through: –Sex with an infected person without using a condom (the efficacy of latex condoms in preventing infection with HIV is unknown, but their proper use may reduce transmission) –Sharing drugs, needles, or "works" when "shooting" drugs –Exposure to blood and body fluids on the job –From an infected mother to her baby when she is pregnant, when she delivers the baby, or if she breast-feeds her baby 4 Leads to the disease AIDS 4 Destroys the immune system

18 HIV/AIDS Symptoms 4 You cannot rely on symptoms to know whether or not you are infected 4 The only way to know if you are infected is to be tested for HIV infection 4 Many people who are infected with HIV do not have any symptoms at all for 10 years or more 4 You also cannot rely on symptoms to establish that a person has AIDS 4 The symptoms of AIDS are similar to the symptoms of many other illnesses 4 AIDS is a medical diagnosis made by a doctor based on specific criteria established by the CDC

19 HIV Prevention 4 Use latex condoms correctly and every time you have sex 4 Dont share, syringes, or works used to inject drugs, steroids, vitamins, etc. 4 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 4 Dont share razors or toothbrushes because of the possibility of contact with blood 4 Do not come into contact with another persons blood or body fluids at work

20 You Cannot Catch Hepatitis B, C, or HIV 4 By working with or being around someone who has the disease 4 From sweat, spit, tears, clothes, drinking fountains, phones, toilet seats, or through everyday things like sharing a meal 4 From insect bites or stings 4 From donating blood 4 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)

21 Other Bloodborne Diseases 4 Syphilis 4 Malaria 4 Brucellosis 4 Babeosis 4 Leptospirosis 4 Arborviral Infections 4 Relapsing Fever 4 Creutzfeld-Jacobs Disease--Mad-cow 4 Viral Hemorrahgic Fever--Ebola
