1 Bloodborne Pathogens Sandy Bennett

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

3 Hepatitis A Caused by infection with Hepatitis A virus Caused by infection with Hepatitis A virus Virus is found in the stool of infected persons 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 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 Occurs in epidemics both nationwide and in communities

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

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

6 Hepatitis B Caused by infection with Hepatitis B virus Caused by infection with Hepatitis B virus Occurs when blood or body fluids from an infected person enters the body of a person who is not immune 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, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth 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, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth Can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death Can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death

7 Hepatitis B Symptoms Jaundice Jaundice Fatigue Fatigue Abdominal pain Abdominal pain Loss of appetite Loss of appetite Nausea, vomiting Nausea, vomiting Joint pain Joint pain

8 Hepatitis B--Prevention A safe and effective vaccine is available 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. 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. 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 Never share drugs, needles, syringes, or "works Do not share personal care items that might have blood on them (razors, toothbrushes) Do not share personal care items that might have blood on them (razors, toothbrushes)

9 Hepatitis C Hepatitis C is a disease of the liver caused by the Hepatitis C virus (HCV) Hepatitis C is a disease of the liver caused by the Hepatitis C virus (HCV) Occurs when blood or body fluids from an infected person enters the body of a person who is not infected Occurs when blood or body fluids from an infected person enters the body of a person who is not infected HCV is spread through sharing needles or "works" when "shooting" drugs, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth HCV is spread through sharing needles or "works" when "shooting" drugs, through needlesticks or sharps exposures on the job, or from an infected mother to her baby during birth Chronic infection: 55%-85% of infected persons Chronic infection: 55%-85% of infected persons Chronic liver disease: 70% of chronically infected persons Chronic liver disease: 70% of chronically infected persons Deaths from chronic liver disease: 1%-5% of infected persons may die Deaths from chronic liver disease: 1%-5% of infected persons may die Leading indication for liver transplant Leading indication for liver transplant Most infections are due to illegal injection drug use Most infections are due to illegal injection drug use

10 Hepatitis C--Symptoms Jaundice Jaundice Fatigue Fatigue Dark urine Dark urine Abdominal pain Abdominal pain Loss of appetite Loss of appetite Nausea Nausea 80% of infected persons have no signs or symptoms 80% of infected persons have no signs or symptoms

11 Hepatitis C--Prevention There is no vaccine to prevent hepatitis C There is no vaccine to prevent hepatitis C Do not shoot drugs and never share needles, syringes, or "works" 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) Do not share personal care items that might have blood on them (razors, toothbrushes)

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

13 Hepatitis E Hepatitis E is a liver disease caused by the hepatitis E virus (HEV) Hepatitis E is a liver disease caused by the hepatitis E virus (HEV) It is transmitted in much the same way as hepatitis A virus Hepatitis E, however, does not occur often in the United States It is transmitted in much the same way as hepatitis A virus Hepatitis E, however, does not occur often in the United States

15 HIV Human immunodeficiency virus 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 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 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 Leads to disease AIDS Destroys the immune system Destroys the immune system

16 HIV Symptoms You might have HIV and still feel perfectly healthy 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 The only way to know for sure if you are infected or not is to be tested

Use a latex condom to reduce the risk of STD transmission. Dont share razors or toothbrushes because of the possibility of contact with blood Dont 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.
