BLOODBORNE PATHOGENS FOR HEALTH RELATED PROFESSIONS & OTHER INFECTIONS DISEASES

  • Version 2.0
  • Revised 05/2007
2
Acquired Immunodeficiency Syndrome  (AIDS)
  • First seen in 1981.
  • Characterized by one or more opportunistic diseases.  (Kaposi Sarcoma)
  • HIV was identified in 1983 as the causative organism.
3
Global status of HIV/AIDS
  • 40.0 million are living with HIV & AIDS
  • In 2001 alone, 3 million people died of AIDS
  • Just under 1 million people in the US have HIV infections (929,985 people)
    • ¼ of these people are unaware of their infection
    • That is 232,496 people are unaware!!!!
4
Global status of HIV/AIDS
  • About 14,000 new infections occur daily
    • 90% of these are in developing countries
  • Majority of new HIV infected adults are <25 years old
  • 11.7 million adults and 4.0 million children have died since the epidemic began
  • Over 8 million children have been orphaned because of AIDS
5
Deaths Due to AIDS in the US
  • Through 2004 it is estimated that
    • 518,568 adults
    • 5,492 children under 13 years
    • Have died of the disease.


6
The Virus
  • Has a protective coating which deters destruction
  • Enters the bloodstream and attacks WBCs called “T cells”.
  • T cells become functionally impaired.
  • HIV antibodies are produced by other WBCs to combat the AIDS virus.
7
Antibodies
  • Can be detected by a simple blood test.
  • Test typically shows presence of virus between 2 weeks to 6 months after infection.
  • However, it may take up to 10 or more years to show signs of the illness.
8
Aids Cases by age in the US
9
AIDS Cases by Race/Ethnicity       in the US
10
Modes of HIV Transmission
  • Accidental exposure to blood/blood products (e.g., blood transfusions, shared needles, contaminated instruments)
  • Mother to child during:
    • pregnancy
    • birth
    • breastfeeding
11
HIV Transmission Through Sexual Contact
  • Of every 100 HIV infected adults, 75B85 have been infected through unprotected intercourse
    • 70% of these infections are from heterosexual intercourse
  • STDs, especially ulcerative lesions in genitalia, increase risk of transmission
12
HIV Transmission
  • HIV cannot be transmitted by:
    • Casual person to person contact at home or work or in social or public places
    • Food, air, water
    • Insect/mosquito bites
    • Coughing, sneezing, spitting
    • Shaking hands, touching, dry kissing or hugging
    • Swimming pools, toilets, etc.
13
Signs and Symptoms
  • Frequent yeast infections
  • Shingles in persons under age 50-60
  • Frequent Herpes
  • Unexplained weight loss
  • Fever of unknown origin
  • Skin rash and cough
  • An infected individual may appear  and feel fine, but is still capable of infecting others.
14
Kaposi Sarcoma
15
Body Fluids
  • The virus has been isolated in all body fluids in varying degrees.
    • Blood
    • Semen
    • Vaginal Secretions
    • Stool
    • Urine
  • These have the highest concentration of the virus.
16
Women and HIV
  • Biological risk factors
    • Twice as easy for women to contract HIV from men
    • Physiology of women (e.g., menstruation, intercourse)
    • Pregnancy-associated conditions (e.g., anemia, menorrhagia and hemorrhage) increase the need for blood transfusion
17
 
18
AIDS Cases by Exposure Category
Estimated # through 2003
19
Risk Factors
  • Sex Between Men
  • Multiple Partners
  • IV Drug Users
  • Hemophilia
  • SO……….Why are we covering these risk factors if they don’t apply to you?……...
20
"Accidental needle sticks with blood..."
  • Accidental needle sticks with blood contaminated needles occur among healthcare providers.
21
HIV and Healthcare Workers
  • Most exposures do not result in infection
  • Risk varies by:
    • type of exposure
    • amount of blood involved
    • amount of virus in the patient’s blood at time of exposure
    • whether post exposure treatment was taken
22
Public Education
  • Another reason you need to know about AIDS is that you have chosen a career in the healthcare profession.
  • Whether you want them to or not, people will ask your advice.
  • You must be informed and educated so that you can properly instruct people on varying topics.
23
PREVENTION
  • You should have a blood test to see if you have been infected with the AIDS virus if:
    • You have been involved in high risk sexual activity.
    • You have shared IV Drug needles.
24
Prevention (cont.)
  • If your test is positive for HIV or you engage in high risk activities and choose not to have a test, you should:
    • Discuss same with your sexual partner.
    • Protect your partner by using a condom.
  • If your partner has tested positive or if you expect exposure, condoms should be used.
25
Prevention (cont..)
  • If you or your partner are at risk:
    • Avoid oral contact.
    • Avoid activities which could cause cuts to the rectum or vagina.
    • Avoid sex with prostitutes.
    • Be aware that needle exchange programs exist throughout the US.
    • Most health departments provide confidentiality and anonymity groups.

26
Treatment
  • Medications are available to lessen the onset of opportunistic infections:
    • AZT
    • DDI
    • HIVID
    • Numerous new drugs have recently been introduced.
  • These are anti-viral agents.
  • To date, no approved immunization or cure is available and the development of one doesn’t appear to be likely soon
27
Pregnancy
  • The need to test all pregnant women for HIV is being considered.
  • Research reveals that 30% of children born to infected mothers are HIV positive.
  • The rate drops to 8% if the mother is properly treated during pregnancy and the newborn is given medication at birth.
28
Effect of AIDS on Pregnancy
  • Infertility
  • Repeated abortions
  • Prematurity
  • Intrauterine growth retardation
  • Stillbirths
  • Congenital abnormalities
  • Embryopathies
29
HIV and Breastfeeding
  • WHO, UNAIDS and UNICEF recommend that all women:
    • be informed of the risk of HIV transmission through breastfeeding,
    • have access to voluntary  counseling and testing to find out their HIV status, and
    • be supported in their choice of breastfeeding or replacement feeding.
30
HIV Transmission  from Mother to Infant
  • 90% of HIV-infected infants and children were infected by their mother
  • 2/3 of babies born to HIV infected women are NOT infected
  • Of infected infants:
    • 2/3 infected in the womb or at birth
    • 1/3 infected via breastfeeding
31
Risk of HIV Transmission from Breastfeeding
  • Risk is increased if:
    • Mother acquires infection while pregnant or during lactation
    • Mother has cracked nipples, abscesses or other breast problems
    • Mother is symptomatic for HIV-related disease
    • Baby has sores in mouth or inflamed gut
32
Nutritional Support
  • The person with AIDS typically presents with weight loss.
  • Their diet is poor.
  • They have no taste for food.
  • Consequently they do not eat well.
  • The diaphragm is one of the first muscles affected by malnutrition.
33
Nutritional Support (cont.)
  • The diaphragm:
    • Is the muscle below the lungs.
    • Helps the lungs to move in and out during breathing.
    • When weakened, allows the virus to invade the lungs
    • Results in Pneumocystis.
34
Pneumocystis Carini
  • Is the most common disease associated with AIDS.
  • May be the mechanism for initial diagnosis.
  • Is a type of pneumonia
  • Is capable of production massive infection in the lungs of the infected individual.


35
Nutritional Support (cont.)
  • It is extremely important for the person with AIDS to  eat a healthy diet.
  • Proteins are the substances of repair for the body.
  • Individuals infected with HIV must be encouraged to eat a high quantity of protein in order to built their muscles.
  • Examples of high protein foods are peanut butter and supplemental protein drinks.
36
Personal Protective Equipment
  • During your career, you will care for a person with HIV.
  • What measures do you need to take?
    • GLOVES, GLOVES, GLOVES!
37
PPE (cont.)
  • HIV has been isolated in every body fluid (including blood, sweat, and tears)
  • The amount of contamination depends on the amount of body fluid involved.
  • Although the virus is present in sweat, there have been NO documentations of infections from contact with a diaphoretic person.
  • Researchers do not believe that tears or sweat transmits the virus.
38
PPE (cont.)
  • SO WHEN DO YOU WEAR GLOVES?
  • Any time and any place where you may come in contact with body fluids that have a high concentration of the virus:
39
PPE (cont.)
  • Any time you expect a large contamination of body fluids, you should wear the full complement of personal protective equipment.


40
Post Exposure Treatment
of Healthcare Workers
  • Intact skin, mouth or nose: immediately wash with soap and water and rinse thoroughly to remove all potentially infectious particles.
  • Cut or punctured skin: allow to bleed fully.
41
Post Exposure Treatment
of Healthcare Workers
  • Eye: flush immediately with water, then irrigate with normal saline for 30 minutes.
  • Consider post exposure prophylaxis (PEP) if high risk of transmission:
    • 4 week course of zidovudine (ZDV)
    • preferable to start within 1-2 hours
42
Post Exposure Treatment of Healthcare Workers continued
  • HIV testing immediately, 6 weeks, 6 months and 12 months
  • Treatment, if started, should continue for 4 weeks. Any or all drugs may be declined by exposed worker.
  • For lesser exposures, prophylaxis is not recommended.
43
What to do if a blood spill occurs?
  • Use a solution of 1:9 bleach and water to disinfect the area.
  • Research has proven that the virus lives outside the body for a considerable time.
  • To prevent other contamination, be sure to clean ANY accidental spillage
44
Emotional Needs
  • What is expected of you?
  • How many of you will be afraid to care for patients with AIDS?
45
OSHA
  • A copy of the Federal Register regarding Bloodborne Pathogens and a copy of the EMS Program’s policy on AIDS & AIDS-related conditions can be found in the office of the EMS Program Director. These documents are available for your review.


46
Hepatitis
  • The term “hepatitis” means inflammation of the liver.
  • Causes of hepatitis include:
    • Toxic chemicals
    • Alcohol
    • Viruses
47
Seven Types of Viral Hepatitis
  • (A through E), are well-recognized.


  • Recently, researchers have identified a sixth type (hepatitis G), and a seventh is suspected but not yet confirmed (hepatitis F).
48
Hepatitis A
  •  Often caused by consuming fecal contaminated food or water.
  •  Produces only acute hepatitis.
49
Hepatitis A
  • Sometimes called infectious hepatitis, although all viral hepatitis is infectious.
  • Vaccine is available and recommended before travel in some parts of the world.
  • The CDC estimates that 150,000 people in the united states are infected each year by hepatitis A.
50
Symptoms of Hepatitis A
  • As is common with the other forms of viral hepatitis, the infected person may not have any symptoms.
  • When they do occur, symptoms resembling the flu normally appear during the first four weeks of infection.
  • These include fatigue, nausea, vomiting, pain in the liver area, dark urine or light colored stools and fever.
51
Symptoms of Hepatitis A
  • Liver function tests are elevated, with many adults developing jaundice.
  • Most people recover from the hepatitis A virus within six months without any serious health problems.
52
Transmission of Hepatitis A
  • Fecal matter from an infected person has a high concentration of the virus.
  • The virus can survive in fecal matter on a person's hand or other surfaces for three to four hours at normal room temperatures.
  • Eating utensils are a frequent source of infection, as are contaminated shellfish and I.V. Drug use.
  • Intimate contact of any kind with an infected person can also transmit the virus.
53
Typical Associations
  • Close quartered institutions
  • Third world countries due to poor sanitation
  • In epidemic forms in U.S. Daycare centers where diapers are changed
  • In some cases, where well water is used
54
Incubation Period
  • Incubation period is 15 to 45 days.
  • This type is not life threatening.
  • Signs and Symptoms may include:
    • Low grade fever
    • Lethargy
    • Nausea, diarrhea, and vomiting
    • Urine may turn dark
    • Feces may turn pale
    • Skin may become jaundiced
55
Treatment
  • There is no specific treatment for    Hepatitis A
  • Palliative treatment includes:
    • Bedrest
    • Good diet
    • Treatment of symptoms
56
Gamma Globulin
  • Some symptoms such as nausea and itching may be treated medically with an injection of Gamma Globulin.
  • This injection reduces the severity of symptoms IF AND ONLY IF it is administered within one week of exposure.
  • Is also administered with Hepatitis B exposure.
57
Hepatitis B
  •  Hepatitis B virus (HBV), formerly called serum hepatitis, is much more prevalent than HIV ( the virus that causes AIDS).
  • Spread in numerous ways including sexual contact, blood products, and contaminated needles.
  • May produce a severe acute hepatitis but only about 5 percent to 10 percent develop chronic hepatitis.
  • Readily preventable by vaccination.
58
Transmission of Hepatitis B
  • Through infected blood and other body fluids (seminal fluid, vaginal secretions, breast milk, tears, saliva and open sores).
  • In the U.S., Hepatitis B is spread predominantly through sexual contact.
  • Other risk groups include health care workers, prison inmates and personnel, IV drug users, and recipients of blood transfusions prior to 1975.
  • In families, it appears that the virus can be casually spread from adults to children.
59
"AS A HEALTHCARE PROVIDER…."
  • AS A HEALTHCARE PROVIDER….
60
"The incubation period is 50..."
  • The incubation period is 50 to 180 days.
  • Symptoms are the same as for Hep A.
  • Jaundice is typically seen with type B.
  • According to statistics, most people fully recover from Hep B in 1 to 2 months.
  • It should be noted, however that 1-2% of individuals with Hepatitis B die shortly after infection due to liver failure.
  • 5-10% develop chronic Hepatitis and become carriers of the disease.
61
Hepatitis B Vaccination
  • As part of your admission to Calhoun’s Health Education Division, you are required to either receive the vaccine or sign a waiver against vaccination.
  • The vaccine involves a series of three injections.
  • Side effects are minimal and may include soreness and warmth at the injection site.
62
"Although there is no guarantee..."
  • Although there is no guarantee of immunity, it is very important that you consider receiving the vaccine.
  • The CDC has made it mandatory for employers to provide vaccinations to healthcare employees because the risk is so much greater for us.
  • Gamma Globulin is administered to boost the effects of previous vaccinations.
63
End Stage Liver Cancer Associated with Hepatitis B
64
Hepatitis C
  •  A blood-borne virus first identified and successfully tested for in 1989.
  • It is most often transmitted by intravenous drug users sharing contaminated needles.
65
Hepatitis C
  • It An estimated 3 percent of the world's population — more than 170 million people — carry HCV.
  • can live undetected in the body for years. In fact, up to 90 percent of people infected with HCV show no symptoms until decades later when damage from the virus' relentless assault on the liver shows up during medical tests.
  • Those infected with the virus carry an increased risk of developing cirrhosis and cancer of the liver.
66
Impact on U.S. From HCV
  • Hepatitis C affects an estimated 4 million people in the U.S., With 30,000 new cases diagnosed annually.
  • By comparison, there are just under a million Americans infected with the AIDS virus (CDC).
  • Currently, about 10,000 Americans die each year from HCV-related disease, compared with 14,000 from aids-related conditions.
          • Source: http://www.mayohealth.org/index.htm
67
According to the World Health Organization (WHO), HCV Has Been Identified in Virtually Every Country in the World.

It Is the Most Common Cause of Post-blood Transfusion Hepatitis, Accounting for About 90 Percent of Cases in the U.S., Japan and Western Europe.

Source: Http://www.mayohealth.Org/index.htm
68
"Effective blood screening has dramatically..."
  • Effective blood screening has dramatically reduced the chances of infection from transfusions.
  • Contaminated drug injecting paraphernalia that is shared is now responsible for about half of all new hepatitis C cases.
  • Those infected with hepatitis C should not donate blood, organs, tissues or semen, according to the CDC.
69
Hepatitis C
  •  Once infected, few become acutely ill, but up to 90 percent develop a chronic infection and 20 percent of those chronically infected individuals develop cirrhosis of the liver.
  •  May be identified by a simple blood test, but no vaccine is currently available.
70
HCV Symptoms
  • 60 to 70 percent of patients with acute HCV infection are asymptomatic.
  • 20 to 30 percent have jaundice.
  • 10 to 20 percent have only fatigue, anorexia and abdominal pain.


71
"HCV ranks second behind alcoholism..."
  • HCV ranks second behind alcoholism among the causes of liver disease and is the leading reason for liver transplants.
  • About 85 percent of people infected with HCV go on to develop chronic hepatitis.
  • About 20 percent develop cirrhosis, an incurable disease, within 20 years.
  • And up to half of those cases progress to end-stage liver disease or liver cancer.
          • Source: http://www.mayohealth.Org/index.htm
72
Risk Factors
  • Contact with persons with jaundice
  • Visits to environments with poor sanitation
  • Ingestion of shellfish or raw fish
  • Recent ear piercing or body tattooing
  • Recent blood transfusions
  • IV drug use (sharing needles)
  • Occupational exposures                        (healthcare workers)
  • Hemodialysis
  • Multiple sex partners
73
Hepatitis D
  • A person must be infected with hepatitis B to acquire this disease.
  • Symptoms similar to hepatitis B.
74
Hepatitis E
  •  Similar to hepatitis A: acute rather than chronic.
  • Very unusual in the U.S. Has produced large outbreaks in Asia and south America.


75
Hepatitis E
  • Symptoms and methods of transmission resemble hepatitis A, although the period of illness may be as long as several months.
  • Caused by a virus commonly found in the Indian ocean region, Africa, and in underdeveloped countries.
  • Testing for hepatitis E is being developed but is not yet available commercially.
  •  Hepatitis E is rarely, if ever, responsible for causes of chronic hepatitis
76
Hepatitis F
  •  Appears to produce a type of hepatitis similar to hepatitis C. But scientists are not yet certain it is a separate hepatitis virus.


77
Hepatitis G
  •  Newly identified.
  • Probably transmitted in a similar fashion to hepatitis C.
  • Scientists are unsure of its impact or how often it produces chronic symptoms or liver disease.
78
Personal Protective Equipment
  • Appropriate protection includes whatever items are necessary to prevent contact with body fluids.
  • Typically, gloves are appropriate.
79
Tuberculosis
  • A necrotizing infection occurring most commonly in the lungs.
  • Also called Pulmonary TB.
  • Transmission is airborne from a source person speaking, coughing, or sneezing.
  • When the infective droplet is inhaled, the body produces an acute inflammatory response within 24 to 48 hours.
80
"The immune system kicks in..."
  • The immune system kicks in within 10-20 days.
  • Blood cells form around the bacteria and encapsulate it.
  • These encapsulated cells dissolve within 13 to 24 weeks and then resemble thick white masses that look live cheese.
  • After this occurrence, the previously encapsulated bacteria spread throughout the lung fields and to other parts of the body.
  • In rare cases, the casing never dissolves, thus the bacteria never activates.
81
Clinical Findings
  • Clinical findings include:
    • Fever
    • Fatigue
    • Weight loss
    • Productive cough
    • Chills
    • Anemia
    • Bloody sputum
82
Treatment
  • Drugs include INH and Rifampin
  • The patient is no longer considered contagious after having received seven days of medication.
  • Potential exposures occur among hospitalized patients who have not been identified as having TB.
83
High Risk Persons
  • Persons with HIV infection
  • Contact with patients recently diagnosed with TB
  • Contact with patients who have had a recent skin test conversion
  • Contact with persons who have been recently diagnosed and inadequately treated
  • Leukemia/lymphoma, diabetes, and end stage kidney disease increase the risk of contracting  TB
84
"As part of your admission..."
  • As part of your admission to Calhoun’s Health Education Division, you are required to receive a two step TB skin test.
  • A positive skin test does not mean that you have TB, it merely means that you have come in contact with the bacteria.
  • Typically, when employed in healthcare, you will be required to have a yearly skin test and physical exam.
  • The number of TB patients in the U.S. is growing and is closely associated with HIV.
85
Personal Protective Equipment
  • Mask
    • TB is an airborne disease.
    • Infected patients must be transported wearing a mask.
86
Phthirius and Sarcoptes
Lice and Scabies
  • Lice are small wingless insects.
  • Three kinds are common in humans:
    • Head lice
    • Body lice
    • Pubic lice (crab lice)
  • Body lice are generally sexually transmitted
  • Spread occurs through physical contact with infested bedding, clothing, hats, towels or hair.
87
Incubation Period
  • Itching may develop at the site of infestation about a month after infestation.
  • In some cases, lice bites may cause a mild rash resembling blue spots.
  • Lice should be suspected in anyone with an itchy eruption in a hairy area of the body.
88
Visualization of Lice
  • A magnifying glass is needed to see adults.
  • Lice appear as small yellow or gray insects unless they have recently fed and look red.
89
Head Lice
90
“Nits”
  • Clinically, you may see the “nits” associated with lice.
  • Head and pubic lice are attached by a cement-like substance.
  • The nit (eggs) are laid at the hair/skin junction.
  • As time goes by, the hair grows out and has a tangled appearance.
91
Treatment for lice
  • Body lice may live for 10 days without a blood meal.
  • Pubic lice live only 1-2 days.
  • Treatment involves using Kwell lotion (a prescription medication).  “Rid” is an over the counter version.
  • Both medications require only one application.
92
Lice treatment (cont.)
  • The lotion is applied undiluted to the infected areas and washed off after about 10 minutes with warm water and soap and shampoo.
  • A comb is then used to remove the dead lice and eggs.
  • Itching may continue for 2 weeks after treatment.
  • Patients should also wash all clothing and bedding in hot water to prevent reinfestation
93
Lice treatment (cont.)
  • In the acute care setting, gloves are sufficient to prevent personal infestation.
  • Normal laundry guidelines treat all bedding as infected and are sufficient to prevent spread through linens.
  • Bedding should be changed after each patient.  (As you will see on clinicals.)
94
Scabies
  • Scabies is a skin infestation by a mite.
  • Scabies is transmitted by physical contact.
  • Typically no symptoms for one month.
  • The symptoms resemble an allergic reaction with the most common being itching.
  • The most common areas of infestation are wrists, webs and sides of the fingers, elbows, around the navel and breasts, and the lower portion of the buttocks.
  • Sometimes, the penis and scrotum are involved.
95
Scabies (cont.)
  • Diagnosis is made by microscopic examination of skin scrapings.
  • Treatment is again Kwell lotion.
  • Symptoms may continue for several weeks.
  • Bedding and clothing should be washed in hot water.
  • Clinically, gloves are appropriate for prevention of transmission.
96
Scabies
97
Herpes
  • Herpes is a class of viruses that include:
    • Cold sores (herpes I)
    • Genital herpes (herpes  II)
  • Herpes I usually infects the mouth and lips and causes the common cold sore or fever blister.
  • Herpes II is almost always sexually transmitted and may lie dormant for years.
  • Ten percent of genital herpes cases are caused by oral to genital contact.
98
Oral Herpes
99
Genital Herpes
100
Herpes (cont.)
  • The average incubation period for genital herpes is 6 days and between 2 & 12 days.
  • Transmission occurs while the virus is shedding.
  • The contagious period begins just before the active outbreak of lesions and continues through the shedding period.
  • Direct contact with actively shedding lesions is usually necessary to contract the virus.


101
Herpes (cont.)
  • Herpes I infections are generally transmitted by mouth to mouth contact.
  • Herpes II is transmitted through sexual contact.
  • The virus may live outside the body for a short time in a warm environment.
  • Chlorine kills the virus on contact.
102
Herpes (cont.)
  • There is no current cure for the herpes virus.
  • Research is underway to develop a vaccine.
  • Sexual activity should be avoided during active periods of the virus.
  • Condoms should be used between active episodes.
  • Consult a physician for treatment.  Sometimes treatment involves hospitalization and IV antibiotics.
103
MRSA:  Methicillin Resistant Staphylococcus Aureus
  • Staph aureus is a gram positive organism {bacteria} that can be cultured from the nose of 30 to 40% of the general population.
  • Generally the organism can be killed with antibiotics.
  • MRSA is a staph aureus that is resistant to the semi-synthetic penicillins.
104
"MRSA was first identified in..."
  • MRSA was first identified in 1961.
  • It first appeared in the U.S. in 1975.
  • Around 1980, a study showed that MRSA was directly related to the cause of death in 44% of the cases studied.
  • MRSA is deadly if not identified and treated properly.
  • Diagnosis can only be made through laboratory testing.


105
Transmission and Prevention of MRSA
  • MRSA is spread from person to person by direct skin contact.
  • Hand carriage by hospital staff is thought to be one of the main methods of spread between patients.
  • It is very important to wash your hands between patients.
  • Hand washing before and after each patient contact with soap and water for a minimum of 20 seconds is the best way to prevent MRSA’s spread.
106
"Other measures to prevent becoming..."
  • Other measures to prevent becoming infected or transmitting infection include:
    • avoid cross contamination between clean & dirty linen
    • daily environmental cleaning
    • wearing gloves for all dressing changes
    • proper handling of medical waste
    • observing isolation precautions
  • Do not let this organism frighten you.  If you simply touch a patient, you are not likely to become sick yourself.
  •    Just be sure to wash your hands
  • before and after each patient contact.
107
Stethoscopes and MRSA
  • Stethoscopes, an almost universal tool of the medical profession, are an additional vector of infection since they touch so many patients.
  • A study in 1992 of 29 stethoscopes found 26 of them contaminated with staph.
  • Five of them had MRSA.
  • Be sure to clean stethoscopes between patients.  Alcohol preps should be sufficient for cleaning.
108
Isolation Precautions
  • First, treat all patients as if they are infectious!!
  • MRSA does require some special precautions.
  • Patients with MRSA should be separated from the general patient population.
  • The area of the body infected determines the amount of PPE needed.
109
"If the organism involves the..."
  • If the organism involves the respiratory system, wear a mask.
  • If the organism is in the urine, gloves are necessary.
  • Gowns and masks are not necessary unless spillage is likely.
  • Urine contamination usually does not require special isolation.
  • Respiratory contamination requires placement in special rooms that filter air more efficiently than normal rooms.
110
"Remember"
  • Remember, MRSA is deadly if untreated.
  • Good hand washing is very effective in preventing transmission.
111
Vaccines
112
Diphtheria, Tetanus, and Pertussis (DTaP)
  • Why get vaccinated?
    • All three are caused by bacteria that can easily enter the body.
    • Diphtheria causes a thick mucus covering to the back of the throat.
    • Tetanus (lockjaw) – causes painful tightening of the muscles, usually all over the body.
    • Pertussis (Whooping Cough) causes severe coughing spells that can lead to breathing difficulties, pneumonia, seizures, and even death.
113
Diphtheria
114
Pertussis and Tetanus
115
DTaP
Who should get it…and when?
  • Children should get 5 doses before age 6.
      • 2 months
      • 4 months
      • 6 months
      • 15-18 months
      • 4-6 years
116
Hepatitis B Virus (HBV)
Why get the vaccine?
