AIDS Acquired Immunodeficiency Syndrome Caused by HIV Human Immunodeficiency Virus
HIV Outcome of infection with the virus varies: • Some have no symptoms. • Some have less severe symptoms than those with AIDS. • AIDS results from destruction of the immune system which allows diseases to threaten life or health.
How Widespread Is HIV ? Worldwide • CDC estimates that 33.6 million people worldwide are living with HIV / AIDS. (32.4 million adults) 2008 • Approx. 5.6 million new HIV infections were reported in 2006. More than 15,000 infections each day. • One in every 100 adults aged 15 to 49 is HIV-infected.
How Widespread Is HIV ? United States • CDC estimates that 650,000 to 900,000 US residents are currently living with HIV infection, of whom more than 200,000 are unaware of their infection. • Approx. 43,000 new HIV infections were reported in 2006 • 711,344 cases of AIDS have been officially reported to the CDC as of June 30, 2005
You Cannot “Catch” HIV: • Through the air • Through casual, everyday contact • (sharing bathrooms, kitchens, etc.) • Through nonsexual social situations • Through insects or mosquitoes • Through urine, feces, nasal secretions, sputum, vomitus, saliva, sweat or tears from an infected person
What Personal Behaviors/Practices Put You at Risk ? • Sexual contact with an infected person • Sharing infected needles • Infected woman to her child at birth • Blood transfusion* *The blood supply is thoroughly screened so that the risk of infection from transfusion is extremely small.
How Can You Prevent HIV Transmission in Your Personal Life? Refrain from: • Vaginal or oral sex with someone who uses IV drugs • Sex with someone you don’t know well • Sex with someone who has multiple sex partners • Sex without a condom - with an infected person • Sharing IV drug needles
Occupational Acquired HIV Infection & AIDS Of the 427,795 infected adults reported to the CDC where the type of job was known, 21,760 were health care workers. Of those, 74% have died.
Occupational Acquired HIV Infection & AIDS There has only been one documented case of patients being infected by a health care worker in the United States. This involved HIV transmission from one infected Dentist to six patients.
Protect yourself from HIV on the job by avoiding contact with blood and potentially infectious body fluids that can transmit the virus
Blood The single most prominent source of HIV in the occupational setting
The risk of HIV infection through contact with feces, nasal secretions, saliva, sputum, sweat, tears, urine and vomitus is extremely low or nonexistent.
Workers May Be Exposed Through: • Needle stick • 47 of the 55 reported health care workers who seroconverted to HIV after exposure were exposed through punctures / cuts. • Mucous membranes of the eyes, nose or mouth • Broken or non-intact skin
Risk of HIV Infection: • Needle stick: 0.3% following needle stick contaminated with blood from a known infected person. • Chapped / broken skin or mucous membranes: less, but not definitively known
HIV Antibodies • Antibodies to HIV in an infected person’s blood can be detected by a test. • Persons usually develop antibodies within 6 to 12 weeks after becoming infected.
How Can You Protect Yourself? • Use Body Substance Isolation (BSI) procedures & equipment. • No preventative vaccine exists at the present time.
What Is Hepatitis B? • Caused by the Hepatitis B Virus (HBV). • Damages the liver, causing symptoms that range from mild or unapparent to severe or fatal. • 25% of infected individuals develop acute hepatitis. • 6% to 10% become HBV carriers. Carriers can develop liver disease and are infectious to others.
Hepatitis B . . . • 12,000 health care workers become infected through occupational exposure each year. • 500-600 infected health-care workers are hospitalized each year. • 200-300 infected health-care workers die each year with associated diseases.
What Personal Behaviors Put You at Risk for HBV Infection ? • Sexual contact with an infected person • Sharing drug needles and syringes with infected person • Since blood supply is screened for HBV, the chance of being infected through transfusion is extremely small.
What Occupational Exposures Put a Worker at Risk for HBV Infection ? Contact with blood or potentially infectious body fluids through: • Needle stick • Broken or non-intact skin • Mucous membranes of eyes, nose and mouth Saliva injected through a human bite can also transmit HBV.
Body Substance Isolation(BSI) The same BSI equipment & procedures that will protect against exposure to HIV will protect the worker against HBV.
Blood tests are available to detect antibodies for HBV in an infected person.
Vaccines provide protection against HBV infection (90% protection for 7 or more years) Vaccines are 70% to 80% effective when given within 1 week of exposure
Personal Protective Equipment Gloves • Disposables protect against blood and fluids • Normally provide no protection against sharps • Must be changed if soiled or torn • Must be changed between handling of different people
Personal Protective Equipment Masks, Eyewear & Gowns • Not necessary unless blood or other potentially infectious fluids are or could be present • Masks & eyewear should be worn together if splashes are anticipated • Gowns or aprons are worn to avoid soaking of clothes
There are no reported cases of HBV or HIV transmission from mouth-to-mouth resuscitation.
Because other diseases can be transmitted this way, protective devices should be used: bag-valve-mask devices pocket masks mechanical resuscitators
How Can You Protect Yourself Against HIV & HBV ? • If you perform tasks that put you in contact with blood, or other potentially infectious body fluids, you should be vaccinated against HBV. • Practice BSI if blood or other potentially infectious fluids are present. • Have PPE readily available.
HIV cannot live in a dry environment for more than a few hours HBV can live in a dry environment for at least 7 days Once the virus is dead - it’s dead. You cannot “reactivate” it by adding water.
Engineering Practices & Control
Universal Precautions • Consider everythingcontagious • Personal Protective Equipment (PPE) • MUST be provided free of charge • PPE is carried on all EMS apparatus • Fire fighting gear offers little or no protection
Contaminated Equipment • If possible, use as much disposable equipment as possible. • Reusable equipment should be decontaminated with a germicidal solution as soon as possible / practical. • Consider patient’s clothing / belongings as contaminated if soiled.
Needles & Sharps Disposal • Needles should not be recapped or manipulated by hand. • Disposable blades and other sharps should be placed in a puncture-resistant container. • Puncture-resistant containers should be readily available at all times. • Scissors, glass, lancets should be considered.
Hand Washing • Wash hands upon arrival at hospital or returning to quarters. • Use utility or designated sink -- not the food preparation area. • Wash thoroughly with soap & water or germicidal cleanser. • Antiseptic hand cleaners should be available for special situations.
