1 Bloodborne Pathogens

2 Why am I Here Today? To protect employees and students against exposure to bloodborne diseases. OSHA requires annual training for employees who are at occupational risk of exposure to bloodborne pathogens Texas public schools are not required to follow OSHA standards however we are dedicated to provide the best for our employees and our students. Purpose of the regulation is to protect employees against exposure to bloodborne diseases which could lead to disease or death

3 Bloodborne Pathogen Definition
Bloodborne: carried in blood Pathogens: microbes that cause disease Bloodborne Pathogens: germs carried in the blood Remember that other body fluids can also carry diseases

4 Occupational Risk Factors
First aid Cleaning body fluid spills Monitoring altercations

5 Communicable Disease Transmission
Airborne- through the air Direct/Indirect- direct contact, or you touched a surface Waterborne Food borne- from food Fecal / Oral Bloodborne- blood or body secretions Airborne: coughs, sneezes germs into the air. Can become infected when germs come in contact with eyes, nose, mouth, respiratory passages. Colds, flu, measles, TB Direct/Indirect: Skin to skin or skin to mucous membrane contact. If you kiss someone with mono, your mouth comes into direct contact with the person’s saliva. Drinking out of a glass after the person infected with mono, indirectly coming into contact with their saliva. Boils, athletes foot, wound infections Waterborne: germs are carried in water. Cholera Foodborne: Carried in contaminated food. Salmonella Fecal/Oral: germs are shed in the infected person’s stool. Poor hygiene and improper handwashing. Hepatitis A, E. Coli Bloodborne: spread through specific and close contact with another person’s infected body fluids. Not spread through food or water. Hep B & C, HIV, syphilis, malaria

6 Personal Risk Factors Unprotected sexual contact Sharing used needles
drug use razors body piercing toothbrushes tattooing Perinatal- can be passed from mother to child during pregnancy Unprotected sexual contact most common mode of transmission Sharing dirty needles drug use body piercing tattooing Perinatal from pregnant mother to infant Blood transfusion most rare mode of transmission

7 Unlikely Sources of Contamination
Feces Urine Vomit Nasal Secretions Sputum Sweat Tears Saliva

8 You Cannot become Infected with these Viruses through Casual Contact
Coughing Sneezing A kiss on the cheek Hugging or shaking hands Drinking fountains Food

9 Three Things Necessary
Person must be infected Port of exit Port of entry

10 Occupational Risk Factors
Contact with infectious body fluids to broken skin Contact with infectious body fluids to mucous membranes Puncture wounds with used needles In a school setting, what are the specific ways that a person could be infected with bloodborne diseases? In order to become infected three things must occur 1. A person must be infected with a bloodborne disease 2. There must be a portal of exit from the infected person 3. There must be a portal of entry into a susceptible individual

11 Three Primary Bloodborne Diseases
HIV Hepatitis B Hepatitis C However, there are other bloodborne diseases that could also pose a risk to you

12 H - human. I - immunodeficiency. V - virus. A - acquired. I - immuno
H - human I - immunodeficiency V - virus A - acquired I - immuno D - deficiency S - syndrome

13 HIV/ AIDS tranmission facts
Attacks the immune system 1cc of blood ,000 viral particles Dies when fluid dries 0.5% risk of infection after exposure No vaccine No cure Recovery Rare

14 Hepatitis: Inflammation of the Liver
Types of Viral Hepatitis Hepatitis A fecal / oral Hepatitis B bloodborne Hepatitis C bloodborne Hepatitis viruses are not all spread the same way Symptoms may be the same but only blood tests can identify the type of virus Hepatitis A much more prevalent than hepatitis B

15 HBV Symptoms- Hep B May or may not exhibit symptoms
May be unaware they are contagious Flu-like symptoms – fatigue, weight loss, fever, diarrhea May require hospitalization Blood and other body fluids are infected

16 Hepatitis B Virus (HBV)
Unprotected sex & sharing needles Strong virus Can live up to one week outside of the body 1cc of blood contains 100,000,000 viral particles Treatment (No Cure)

17 Those who should be tested for HBV, HIV, but not for HCV
People with multiple sex partners People with an infected steady partner Anyone post needle stick

18 Hepatitis B Vaccination
Three injections over 6 months Booster doses are not recommended. % effective after series is completed

19 Hepatitis B Vaccination Most Common Side Effect
Slight soreness at the injection site (17%) More serious reactions may occur in 1% of vaccinations given

20 Hepatitis C Virus (HCV)
Most common bloodborne infection in US More concentrated than HIV Most people have no symptoms No Vaccine No effective post-exposure prophylaxis Treatment effective in % 85% develop chronic infection Leading indication for liver transplants

21 Standard Precautions An approach to infection control where all human body fluids of all persons are treated as if known to be infectious for communicable diseases

22 Personal Protective Equipment
Gloves- demonstration disposable utility Goggles Gowns Location of gloves and spill kits Fanny packs for playground duty Glove demonstration

23 Use of Disposable Gloves
Think about what you touch while your wearing them! Properly dispose of contaminated gloves in the trash. Wash hands after using them. Waterless hand cleaner as temporary measure only.

24 Handwashing THE SINGLE MOST EFFECTIVE BARRIER TO PREVENT THE TRANSFER OF GERMS is to use soap and running water. Scrub for at least 30 seconds, rinse well, dry with paper towel (use to turn off faucet)

25 Types of Waste Found in School Setting
Sharps containers Regulated waste Contaminated but not regulated Handling Sharps Never bend or break needles Discard in leak-proof, puncture-proof container, labeled with biohazard symbol Never throw sharps container in regular trash; must be handled by biomedicaL waste hauler Only designated employees who have received bloodborne pathogens training should handle or dispose of contaminated articles Sharps from biology or art classes are not considered biohazard unless they are contaminated with body fluids They should be disposed in puncture proof container to protect custodians

26 Exposure Incident a specific eye, mouth , other mucous membrane, non-intact skin, or parenteral (contaminated needles and sharp instruments), contact with blood or other potentially infectious materials that results from the performance of an employee’s duties.

27 Exposure Incident How they occur in the hospital environment
Personal protective equipment failure Equipment may not be readily available Employee may not know how to use equipment Employee may choose not to use equipment Failure of protective equipment Definition: This is defined as any accidental contact with any body fluids that occur at work to any employee

28 What Should I Do If I Have An Accidental Contact With Body Fluids?
Wash area thoroughly with soap and warm water Contact Mrs. Hoffman or Dr. Pate immediately!!!! Report to supervisor

29 Quiz true or false Blood is the single most important source of HIV, HBV and HCV in the work place. People infected with HBV do recover There are vaccines to prevent HBV

30 HBV, HCV, and HIV spread most easily through contact with contaminated blood.
You can be exposed to BBP at work if blood or other infectious material contacts your broken skin or mucous membranes. Feces, urine & vomit can put you at risk of exposure to BBP whether or not they contain visible blood.

31 You need to wash your hands after removing gloves only when you touched the contaminated side of the a glove. Hand washing is your main protection against the spread of infection HBV can survive in dried blood on surfaces for at least one week Universal Precautions were developed to prevent the transmission of BBP when providing first aid and health care.

32 Always use a pocket mask or other respiratory device when you have to resuscitate someone in an emergency. It is not advisable to encourage victims to administer their own first aid. An athlete who is injured and bleeding should stop play immediately and have the wound cleaned and bandaged before returning to game Most exposures to blood result in infection
