| You Are At Risk! As a healthcare worker, you come into contact with bloodborne pathogens. These are infectious organisms, usually viruses, which live in human blood and other potentially infectious body fluids.The most important ones are...
Hepatitis B Virus (HBV)
Human Immunodeficiency Virus (HIV)

| How can HBV be prevented? You can avoid exposure to Hepatitis B by taking the appropriate precautions which include:
Hepatitis B vaccine
Standard precautions
Proper work practices
Personal protective equipment

| How is HBV Spread? Hepatitis B most often spreads when certain body fluids from an infected individual come in direct contact with another person.Contact may occur through:
a break or sore in the skin
a contaminated sharp
contact with mucous membranes that line the insides of the mouth, nose, eyes, and the genital organs.
HBV is not spread through casual contact, such as handshake, or through sweat. | View Page |
| What Causes HBV? Hepatitis B is caused by the Hepatitis B virus, or HBV.The virus travels through the blood stream to infect the liver. | View Page |
| Who is infected? Patients with Hepatitis B and other bloodborne infections can appear healthy, so you can't tell whose blood is infectious.So treat all:blood, body fluids, secretions (except sweat), excretions, non-intact skin, and mucous membranes as if they were infectious.That's what the term Standard Precautions means. | View Page |
| How common is HBV? Up to 1% of the U.S. population harbors the Hepatitis B virus in their bloodstream. In 1990, workplace exposure gave rise to an estimated 8,000 cases of HBV resulting in 200 to 300 deaths from acute and chronic HBV. So occupational exposure to HBV is a serious problem. | View Page |

| The Hepatitis B Vaccination The Hepatitis B Vaccine is one of the most important ways to prevent infection. About 90% of people who receive it get immunity.The present recombinant vaccine is made by genetically altered bakers yeast and contains no blood components. It is very safe.Side effects are minimal. Symptoms such as temporary soreness at the injection site, mild fever, or joint pain may occur but are rare.The procedure consists of three shots in the upper arm given over a six month period.The OSHA standard requires that employers provide the vaccine free of charge to you if your occupation puts you at risk. You may decline the vaccine; but you will be asked to sign a Declination Statement. | View Page |
| Avoiding exposure Only you can protect yourself from bloodborne pathogens.Therefore...
Use Standard Precautions,

And always think about how to perform each task in a way that minimizes your risk of exposure to bloodborne pathogens.

| Important bloodborne pathogens The most important bloodborne pathogens are: Hepatitis B and C & Human Immunodeficiency Virus (HIV).
Hepatitis B is very infectious via the blood-borne route. 30% of needle-sticks from patients who are Hepatitis B will result in infection.
Hepatitis C is much more common in the United States.
HIV is rarely transmitted via needle-stick injury. Nevertheless, utmost care is needed, because of its very serious nature. HIV is not transmitted by casual contact.

| Safety and Handling of Controls To ensure the safety of those performing patient testing, controls do not contain HIV or the hepatitis B virus. Manufacturers place the same batch of control material into small vials. This allows only a small portion of the control to be handled while the remainder is stored until needed. Storage information for controls is printed on the label. These instructions should be followed carefully in order to prevent contamination or false results.
