Bloodborne and Airborne Pathogens Introduction to the Bloodborne Pathogen Standard Chapter 1 McGraw-Hill/Irwin Copyright 2009 by the National Safety Council. All rights reserved

OSHA Bloodborne Pathogen Standard Designed to eliminate or minimize employees exposure to human blood and other potentially infectious materials (OPIM) in the workplace Went into effect in 1992 1-3

Who is covered? All employees who may reasonably expect to be exposed to blood and OPIM that may contain pathogens Anyone whose job involves handling or possibly being exposed to blood or blood products, or OPIM

1-4 What are pathogens? Germs transmitted from one person to another Germs transmitted from one person through contact with bloodtooranother

OPIM through contact with blood or OPIM Microscopic Germs 1-5 Caution! You do NOT need to directly contact someone carrying a bloodborne pathogen to be at

risk for exposure! Risks also come from: Clinical specimens Biohazardous trash Blood- or body fluid-soaked laundry Needles or sharps 1-6

Annual Training Required: How diseases are transmitted and their symptoms Protective measures to prevent exposure Procedures to be followed if exposed 1-7 Exposure Control Plan OSHA requirement Must describe:

Exposure prevention Engineering and work practice controls Universal precautions Personal protective equipment OSHA record keeping requirements 1-8

Other Regulations Needlestick safety and prevention act Identify, evaluate, and implement safer medical devices Keep sharps injury log 1-9 Bloodborne Pathogens Chapter 2

McGraw- Copyright 2009 by the National Safety Council. All right Infectious Disease Transmission Stages of Disease Stages of Disease Transmission: Transmission: 1. Someone has the infection. 2. The infectious

pathogen leaves the infected persons body. 2-11 Infectious Disease Transmission: 3. The infectious pathogen reaches another person and

enters his or her body. Transmission: - Bloodborne - Bloodborne - Airborne - Airborne - Vector - Vector - Direct or indirect contact

- Direct or indirect contact 4. The second person develops the infection. 2-12 Serious Bloodborne Pathogens Hepatitis B virus (HBV) Hepatitis C virus (HCV) Human immunodeficiency virus (HIV)

HIV Virus 2-13 Measures Measures you take to prevent HBV, HCV, and HIV also help prevent diseases caused by other bloodborne

pathogens 2-14 OPIM Saliva containing blood Semen Vaginal secretions Breast milk Amniotic fluid

Blood in saliva during dental exam 2-15 OPIM Cerebrospinal fluid Synovial fluid Pleural fluid 2-16 OPIM Peritoneal fluid

Pericardial fluid Any body fluid visibly contaminated with blood (such as vomit or urine) 2-17 Do Exposures Always Cause Infection? NO The risk of infection

after an exposure depends on: Whether pathogens are present in the source blood or body fluid The number of pathogens present The type of injury or exposure Your current health and immunization status

2-18 Hepatitis B 2-19 Hepatitis B Caused Causedby by hepatitis

hepatitis BBvirus virus (HBV) (HBV) Transmitted Transmittedby by blood bloodand andOPIM OPIM Found Found in inall

allbody body fluids fluids Blood Bloodand andsemen semen are arethe themost most infectious infectious

2-20 Hepatitis B Major Major cause causeof of liver liverdamage, damage, cirrhosis, cirrhosis, and andliver liver cancer

cancer Infections Infections are aredeclining declining Still Stillinfects infects about about 60,000 60,000people peopleyearly yearly

About About 3,000-5,000 3,000-5,000people peopledie dieof of liver liver problems problems associated associated with with HBV HBV infection

infection every every year year 2-21 HBV Incubation period averages 12 weeks Infection can Cause acute hepatitis or A chronic (long-term) infection Chronic HBV can be infectious for decades

2-22 How is HBV Spread? Injection Needlesticks Puncture wounds Mucous membranes Eyes and mouth Nonintact skin (abrasions)

Sexual activity Infected mother to newborn at birth 2-23 HBV Transmission Contaminated environmental surfaces At room temperature HBV may survive for several days in dried body fluids on surfaces HBV more easily transmitted than HIV: - Lives longer outside the body - Little blood needed to cause infection

2-24 HBV not transmitted by: Food or water Fecal matter Through the air sneeze or cough Casual contact shaking hands, hugging, kissing, or sharing a meal,

utensils, or a drinking glass 2-25 Symptoms of HBV About 30% have no symptoms at all Flu-like symptoms may appear gradually Loss of appetite Nausea, vomiting Fatigue Muscle or joint aches Mild fever

Stomach pain Occasionally jaundice 2-26 How Do I Know If I Have HBV? Only certain way to know is to have a blood test Blood test may not indicate the virus shortly after being infected 2-27 Hepatitis B Vaccine

Best protection No risk of developing hepatitis Three doses given by injection on three different dates Most common reaction is soreness at the injection site 2-28 HBV Vaccine Recommended:

Employees at risk Those who have unprotected sex with a partner who has HBV or have sex with more than one partner People who have anal sex 2-29 HBV Vaccine Recommended: Those who use intravenous recreational drugs

People with hemophilia Those who frequently travel to or live in countries where HBV is common Those who live with someone with lifelong HBV 2-30 HBV Vaccine Effectiveness Prevents hepatitis B in ~ 95% of people After receiving the three shots, you

can be tested to make certain you are protected Important if you have a compromised immune system or your job frequently exposes you to human blood 2-31 OSHA Standard and HBV Vaccine Requires employers to offer the HBV vaccine to employees at risk at no cost, at a convenient time and

place, and during their normal work hours You have the right to: Refuse the vaccine (You must sign a declination form) Change your mind and have the vaccination at a later date 2-32 OSHA Standard Requires Employers to: Offer training and HBV vaccine before starting a work assignment Explain to employees that vaccination is voluntary

Make certain employees receive proper medical treatment following any exposure 2-33 Prevention of HBV Infection Get the HBV vaccine Use barrier devices to prevent contact with any blood and OPIM Handle sharps carefully Avoid recreational IV drugs,

tattooing, and body piercing without sterile tools Do not share personal items 2-34 Hepatitis C 2-35 Hepatitis C Liver disease caused by the hepatitis C virus (HCV) Lives in the blood of people with the disease

Spread via the blood Incubation period averages 7 weeks 3.2 million people in the U.S. have chronic HCV infection 2-36 Hepatitis C About 26,000 new infections occur each year Many people who carry HCV have some liver damage but do not get sick from it Other people develop cirrhosis of the liver, resulting in eventual liver failure

2-37 How is HCV Spread? Most often through drug injections with contaminated needles Unclean tattoo or body piercing tools Sharing contaminated toothbrushes, razors or other personal items

2-38 How is HCV Spread? From a pregnant woman to the fetus Rarely, though sexual contact In healthcare, via direct contact with infectious blood through an accidental needlestick or sharps injury 2-39 Symptoms of HCV

Most infected people do not have symptoms Some have: - Fatigue - Loss of appetite - Nausea - Anxiety - Weight loss - Alcohol intolerance - Abdominal pain

- Loss of concentration - Jaundice 2-40 How Do I Know If I Have HCV? Blood test A false positive test can occur with HCV tests Positive tests should have a follow-up test False negative test results may also occur with HCV usually shortly after infection when antibodies have not yet developed 2-41

HCV Testing Anyone who has: Been exposed to HCV-positive blood Used intravenous recreational drugs Received a blood transfusion or organ transplant Been on kidney dialysis prior to 1992 Been treated with a blood product prior to 1987 Signs of liver disease 2-42

HCV Testing Is Important Treatment can be given to protect the liver from additional damage HCV carriers can take preventive measures to avoid spreading HCV to others 2-43 Prevention of HCV Infection No vaccine available for HCV and there is No cure

Prevention is critical 2-44 Preventive Measures Handle needles and other sharps with caution Use barriers to prevent contact with blood and OPIM (wear gloves)

Avoid recreational intravenous drug use Never reuse or share syringes, or drug paraphernalia 2-45 Preventative Measures Dont share toothbrushes, razors, personal care items Get vaccinated against HBV Remember the health risks associated with tattoos and body piercing if tools are not sterile or sanitary practices are not followed

2-46 HIV and AIDS 2-47 HIV and AIDS Human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS) There are almost one million HIV-positive people in the U.S. of people are

unaware of their HIV infection 2-48 HIV and AIDS AIDS damages cells essential for immune function People with AIDS are more susceptible to opportunistic infections The disease is eventually fatal 2-49

How Is HIV Spread? Through an infected persons body fluids: Blood Semen Vaginal secretions

Breast milk OPIM if blood is present 2-50 Transmission in Healthcare Some health workers are infected with HIV through workrelated exposures involving blood or OPIM 2-51 Transmission in Healthcare Infection is most likely to occur with exposure to HIVcontaminated blood, blood components, or blood

products through: Injection Injectionthrough throughthe theskin skin Unprotected Unprotectedmucous mucous membranes membranes An

Anopen openskin skinwound wound 2-52 HIV not Transmitted Through Casual Contact: Sharing a drinking glass, a meal, or fork Kissing, hugging, or touching Sneezes or coughs Sharing a phone or bathroom

With mosquitos, fleas, ticks, or other bloodsucking vermin 2-53 Symptoms of HIV Many people with HIV have no symptoms HIV can take many years to develop into AIDS Microscopic HIV Virus 2-54 AIDS Symptoms

Loss of appetite Weight loss

Fever Skin rashes Swollen lymph nodes Diarrhea Tiredness Night sweats Inability to fight off infection 2-55 How Do I Know If I Have HIV?

A blood test The result is usually positive 12 weeks after exposure A confirmation test is recommended 6 months after an exposure 2-56 Prevention of HIV Infection No vaccine available for HIV and there is No cure Prevention

is critical 2-57 Prevention of HIV Infection Regular hand washing Use of barriers Universal precautions 2-58

3-113 Airborne Pathogens Chapter 4 McGraw-Hill/Irwin Copyright 2009 by the National Safety Council. All rights reserved OSHA Regulations

Specific employee protections not currently mandated Airborne Diseases OSHA expects employers to protect employees from known hazards 4-115

Three Types of Airborne Pathogens Viral Bacterial Fungal 4-116 Airborne Precautions for tuberculosis

also lower the risk for other airborne pathogens Pathogens Meningitis Influenza Pneumonia Tuberculosis

4-117 Airborne Pathogens Spread by inhaling the germ Coughing or sneezing tiny droplets of moisture into the air containing pathogens Pathogens can remain airborne for several hours 4-118

Airborne Transmission Depends On: How contagious the infectious person is Where the exposure occurs How long the exposure lasts How healthy you are at the time of the exposure 4-119

Tuberculosis 4-120 Tuberculosis 14,000 cases in 2005 in U.S. Caused by a specific bacteria Affects the lungs but it can also affect: brain spine kidneys Many people with TB infection are not sick (the body

effectively fighting the bacteria) and are not contagious 4-121 Tuberculosis Those with TB disease are contagious 5%-10% of people develop the disease at some point

Risk is higher for people with HIV, diabetes mellitus, severe kidney disease, low body weight, or certain types of cancer 4-122 Tuberculosis HIV infection is most important risk factor for progression from latent TB infection to TB disease Progression to TB disease is rapid among HIV-infected people TB outbreaks can rapidly expand in HIV-infected patient

groups CDC recommends HIV testing for all TB patients 4-123 Employees at Risk

Correctional facilities Drug and treatment centers Homeless shelters Healthcare facilities Long-term care facilities Morgues 4-124 How Is TB spread?

Inhaling the TB pathogen after an infected person coughs or sneezes The TB pathogen can live up to 1 hours outside the body Infection detectable 2-12 weeks after infection Some bacteria lay dormant for years 4-125 Symptoms of TB Many people with

TB infection have no symptoms! With TB disease: Weight loss Fever Night sweats 4-126 Symptoms of TB If TB affects the lungs, the

common symptoms include: Coughing Production of sputum Chest pain Coughing up blood

4-127 Tests to Determine TB Infection Tuberculin skin test (Mantoux test) -Performed on the skin in lower arm -Result is checked after 2-3 days A blood test (QFT-G) also reveals if a person is infected 4-128 Special Considerations for TB

Testing Generally recommended for employees at risk because of being near people who may have TB:

Certain healthcare facilities Certain healthcare facilities Drug treatment facilties Drug treatment facilities Homeless shelters Homeless shelters Nursing homes Nursing homes Prison and jails Prisons and jails

4-129 Special Considerations for TB Testing Testing recommended for at-risk employees Pregnant employees should be tested via TST, not GFT-G Consider booster effect Those with other disease or illness more likely to develop TB Use 2-step testing for those who will take TST

periodically 4-130 How Do I Know If I Have TB? Skin and blood tests cannot distinguish between TB infection and TB disease Chest x-ray and phlegm sample needed to determine diagnosis

4-131 Preventing TB Infection Administrative controls Environmental controls Respiratory controls 4-132 Administrative Controls Consider the most important

control measure: Assign responsibility for TB infection control Work with health department Ensure timely lab processing and reporting Implement effective work practices 4-133 Administrative Controls, continued Consider the most important

control measure: Test and evaluate workers at risk Train workers about TB infection control Ensure proper equipment cleaning Use appropriate signage 4-134 Environmental Controls These controls remove or inactive M. tuberculosis:

Local exhaust ventilation General ventilation Air cleaning methods - HEPA filtration - UVGI 4-135 Respiratory Protection Controls Used in settings where other controls will not prevent

inhalation of infectious droplet nuclei Implement respiratory protection program Conduct annual training in respiratory protection Initial and periodic fit testing Training patients in respiratory hygiene 4-136

TB Exposure and Recordkeeping Exposure to a known TB source should be reported to employer Employees have right to know about exposures After exposure employees may be tested for TB If infected, employer will arrange for appropriate treatment 4-137 TB Exposure and Recordkeeping Employers must maintain records

Active TB disease must be reported to public health officials OSHA 300 log used to record work-related exposure and infection 4-138 Treatment of TB Depends on: Age Overall health Lifestyle

Occupation TB disease can be cured with antibiotics 4-139 Definition of Flu Flu is a virus that infects the respiratory tract 4-140

How Humans Spread Flu 4-141 How Humans Spread Flu Transmission Vehicles Hands Air Contaminated Objects 4-142

How Humans Spread Flu Entry Points Mouth Eyes Nose 4-143 Flu Symptoms

Cough Running or stuffy nose Thick mucus Muscle pain Stiffness

Fatigue 4-144 Flu Symptoms, continued

Headache Sore throat Shaking chills Fever Dehydration Difficulty breathing 4-145 Steps to Prevent Flu 1. Hand hygiene

2. Respiratory hygiene 3. Social distancing 4. Flu shot 4-146 Hand Hygiene 4-147 Respiratory Hygiene 1. Cough or sneeze into a tissue, or into upper sleeve

2. Dispose of tissues in waste can 3. Avoid touching your eyes, nose or mouth 4. Wear a surgical mask 4-148 Social Distancing 1. Avoid crowded settings 2. If you have to be in a crowd, make the time short 3. Avoid sick people, or keep a distance of six feet

4. If you or your children are sick, stay home 4-149 Immunization Protects from seasonal flu Does not prevent bird flu 4-150 If You Are Sick 1. Stay home!

2. Get plenty of rest 3. Drink lots of fluids 4. Avoid alcohol and tobacco 5. Take medication 6. Call your doctor if you have a high fever 7. Wear a surgical mask 4-151 Caring for the Sick 1. One person should give care 2. Avoid mingling items

3. Disinfect objects touched by the sick 4. Wash your hands frequently 5. It is okay to mingle dishes and laundry, but wash them in very hot water 6. Wear disposable gloves 4-152 Seasonal Influenza Occurs every year Everyone gets it at some point Most people have some immunity and can get a

vaccine for more immunity Can cause severe illness and death 4-153 Bird Flu Infects wild birds and domestic poultry Can have a high death rate Has jumped species to infect humans

Concern that humans can infect one another if virus mutates 4-154 Epidemic An outbreak of a disease in a community or a region 4-155

Pandemic An outbreak that spreads beyond a community or region throughout the world 4-156
