What are bloodborne pathogens? As indicated by OSHA Standard 1910.1030, " Bloodborne Pathogens" implies pathogenic microorganisms that are available in human blood and can bring about sickness in people. These pathogens incorporate, yet are not restricted to, hepatitis B & C infections and human immunodeficiency infection (HIV).Slide 11
Topics of Discussion Related Diseases Modes of Transmission Emergency ProceduresSlide 12
Bloodborne pathogens include: Hepatitis B (HBV) Hepatitis C (HCV) Human Immunodeficiency Virus (HIV)Slide 13
Hepatitis B (HBV) In the United States, roughly 300,000 individuals are contaminated with HBV yearly, however just a little rate is lethal. HBV at first causes aggravation of the liver, yet it can prompt more genuine conditions, for example, cirrhosis and liver disease.Slide 14
HBV (cont.) Symptoms are especially similar to a mellow "influenza", including exhaustion, conceivable stomach torment, loss of craving, and even sickness. After presentation it can take 1-9 months before side effects get to be recognizable. Inoculations are accessible.Slide 15
Human Immunodeficiency Virus (HIV) AIDS, or AIDS, is brought on by an infection called the human immunodeficiency infection, or HIV. Once a man has been tainted with HIV, it might be years before AIDS really creates. HIV assaults the body\'s resistant framework, debilitating it with the goal that it can\'t battle other savage ailments.Slide 16
Symptoms of HIV disease can differ, however regularly incorporate shortcoming, fever, sore throat, sickness, migraines, looseness of the bowels, a white covering on the tongue, weight reduction, and swollen lymph organs. A contaminated individual may convey the infection for a considerable length of time before side effects show up. HIV (cont.)Slide 18
Hepatitis C Virus (HCV)... Hepatitis C infection, some time ago known as "non A-non B", is another pathogen that you should know about on the off chance that you have word related presentation to human blood or other possibly irresistible materials. Hepatitis C is a standout amongst the most well-known sorts of hepatitis with up to 1.5% of the populace been certain.Slide 19
HCV (cont.) Hepatitis C infection (HCV) has been found in all parts of the world where it has been looked for. The infection has all the earmarks of being transmitted most productively through parenteral presentation to blood from a tainted person. Regular case of transmission occasions are: getting a blood transfusion from a contaminated source or offering intravenous medication needles to a tainted person.Slide 20
Comparing HBV and HCV... Like HBV, indications of hepatitis C infection can extend from no side effects or influenza like side effects to jaundice and even passing in uncommon cases. No less than 30-half of patients are absolutely asymptomatic even with genuinely dynamic malady. Additionally like HBV, hepatitis C infection has a transporter state which can prompt interminable contamination and liver ailment .Slide 21
Comparing HBV and HCV… (cont.) Unlike HBV, there is presently no antibody for hepatitis C accessible and immuneglobulin controlled after presentation does not give off an impression of being extremely compelling in averting hepatitis C disease .Slide 22
sexual contact sharing of hypodermic needles from moms to their infants at/before birth unintentional cut from tainted needles, broken glass, or different sharps Modes of Transmission HBV and HIV are most regularly transmitted through :Slide 23
Modes of Transmission (cont.) Contact between broken or harmed skin and contaminated body liquids, contact between mucous films and contaminated body liquids.Slide 24
Modes of Transmission (cont.) Anytime there is blood to blood contact with tainted blood or body liquids, there is a slight potential for transmission.Slide 25
In most work or lab circumstances, transmission is destined to happen due to inadvertent cut from tainted needles, broken glass, or different sharps; contact between broken or harmed skin and contaminated body liquids; or contact between mucous films and tainted body liquids. Methods of Transmission (cont.)Slide 26
Use alert at whatever time you are working with blood or other organic liquids in ANY setting… ...Slide 27
Contaminated blood or organic liquids may bring about transmission through the eyes.Slide 28
Importantly, people tainted with either HIV or HBV may not demonstrate any side effects of ailment, but rather can possibly spread the sickness in specific situations (for instance, contact with their contaminated blood).Slide 29
Transmission Risk... In spite of the fact that the danger of HCV transmission is as yet being characterized, the danger of transmission by the accompanying courses seems, by all accounts, to be low: normal family unit contact circumstances, sexual contact, and passing the disease from mother to unborn kid.Slide 30
Transmission Risk… (cont.) Cases of transmission of HCV to human services laborers have happened through coincidental needlesticks, cuts with sharp instruments, and blood sprinkles to the eye.Slide 31
Transmission Risk… (cont.) Recent studies have demonstrated that the danger of transmission for HCV through a parenteral presentation is ~ 1.8% or 18 in 1000, some place amongst HBV and HIV.Slide 32
Transmission Risk… (cont.) Because there is no treatment or antibody for HCV, anticipating exposures through committed utilization of all inclusive safeguards and safe lab practices is the best approach to decrease transmission of HCV, and also other BBP\'s, in the working environment.Slide 33
Emergency Procedures Personal Protection Clean-up ProceduresSlide 34
TREAT ALL BLOOD AND BODY FLUIDS AS POTENTIALLY INFECTIOUSSlide 35
Personal Protection Skin shields from pathogens-cuts, dermatitis, drying, little splits permit germs to enter the bodySlide 36
Personal Protection (cont.) For medical aid and tidying up-USE gloves and have as meager contact as could be expected under the circumstances with blood or body liquids.Slide 37
Proper strides for expelling gloves 2 1 4 3 5 6Slide 38
Personal Protection (cont.) Wash hands altogether with antibacterial cleanser.Slide 39
Clean-up ProceduresSlide 40
After a mishap, access to the tidy up territory must be confined to staff include in the tidy up.Slide 41
The whole territory must be cleaned of all blood and natural liquids utilizing a disinfectant, (for example, chlorine dye weakened in water-10:1).Slide 42
For EPA enlisted items marked for use against HIV contact: National Antimicrobial Information Network http://www.ace.orst.edu/data/nain/records/listc99a.htm Example : Product: #25 QUATERNARY AMMONIUM CLEANER-DISINFECTANT EPA Reg#: 421-434 Manuf: J. F. DALEY INT\'L LTD, DBA JAMES VARLEY Approval Date: 09/08/82 Active Ingredients (%): Alkyl* dimethyl benzyl ammonium chloride *(50%; C14, 40%; C12, 10%; C16) 5.0000 %; Didecyl dimethyl ammonium chloride 2.2500 %; Octyl decyl dimethyl ammonium chloride 3.7500 %; Dioctyl dimethyl ammonium chloride 1.5000 %Slide 43
Use expendable towels to splash up a large portion of the blood and appropriately discard promptly after use.Slide 44
Be ready for sharp questions, for example, broken dish sets and utilized syringes. Try not to lift these up-utilize a brush or a sweeper and dustpan.Slide 45
Be certain to discard ALL waste appropriately.Slide 46
Put every single sullied towel and waste in a fixed shading coded or marked airtight holder. Discard it as controlled waste.Slide 47
Remember… .. After mischance tidy up, wash hands and expel defensive dress before eating, drinking, applying lip analgesic, or participating in some other exercises that could possibly transmit the blood-borne pathogen. Incessant hand washing is the best safeguard against spreading disease.Slide 48
Finally… . Ensure yourself on and off the employment know the realities. Take after work rules-use gloves and defensive attire. Keep ranges clean-report issues promptly to chiefs.Slide 49
