For a bloodborne pathogen to be spread, the bodily fluids of an infected person must enter into the bloodstream of another person. The most common cause of transmission in the workplace is when an infected person's blood enters another person's bloodstream through an open wound .
What are the modes of transmission of blood borne pathogens?
- semen.
- vaginal secretions.
- cerebrospinal fluid.
- synovial fluid.
- pleural fluid.
- peritoneal fluid.
- amniotic fluid.
- saliva (in dental procedures), and.
What is the most common bloodborne infection?
Human immunodeficiency virus (HIV), hepatitis B virus (HBV) , and hepatitis C virus (HCV) are three of the most common bloodborne pathogens from which health care workers are at risk. However, bloodborne pathogens are implicated in the transmissions of more than 20 other pathogens (Beltrami et al 2000 ).
Which blood borne disease is most contagious?
A bloodborne pathogen is a type of bacteria or virus that lives and thrives in your blood. These pathogens include some of the most contagious diseases we are aware of today, such as HIV/AIDS, hepatitis B, and hepatitis C .
Is blood borne a mode of transmission?
Bloodborne pathogens are most commonly transmitted through:
Contact between broken or damaged skin and infected body fluids . Contact between mucous membranes and infected body fluids . Sexual Contact .
Can you catch disease from touching blood?
If you have contact with a person's blood or body fluids you could be at risk of HIV , hepatitis B or hepatitis C, or other blood borne illnesses. Body fluids, such as sweat, tears, vomit or urine may contain and pass on these viruses when blood is present in the fluid, but the risk is low.
Are hepatitis B and C serious bloodborne diseases?
The main bloodborne pathogens of concern are hepatitis B virus (HBV), hepatitis C virus (HCV) , and human immunodeficiency virus (HIV), the organism that causes AIDS.
What are the main blood borne viruses?
The most prevalent BBVs are:
human immunodeficiency virus (HIV)- a virus which causes accuired immunodeficiency virus (AIDS), a disease affecting the body's immune system; hepatitis B (HBV) and hepatitis C; BBVs causing hepatitis, a disease affecting the liver.
How can you get immunity from blood borne diseases?
Most exposures to bloodborne disease can be prevented through the use of barrier methods (e.g., condoms ) during sexual intercourse, avoidance of injection drug use, and the use of screened blood for blood transfusions.
What is vector borne transmission of disease?
Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods , such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
How do you prevent a blood borne infection?
Wear appropriate personal protective equipment: gloves, goggles, etc. as required by the accident. When performing CPR, always use a pocket mask equipped with a one way valve to prevent contact with potentially infectious body fluids. Contain spills immediately, then clean up and disinfect the area.
What happens to 20% of those infected with HCV?
Approximately 20% of those infected with hepatitis C will naturally clear the virus from their body within the first six months . For the remaining 80% a chronic (long-term) infection will develop. The course of a chronic hepatitis C infection is extremely varied and unpredictable.
Can touching dry blood harm you?
Simply touching blood – even dried blood can be extremely dangerous . What appears to be “dry” blood may, in fact, have only been spilled hours before and therefore still have pathogens in it that are infectious. In the right environment, it could even still pass along diseases including HIV and more.
What diseases are spread through bodily fluids?
- hepatitis B – blood, saliva, semen and vaginal fluids.
- hepatitis C – blood.
- human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.
- cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.
What is blood borne transmission?
Bloodborne Pathogens can be transmitted when blood or body fluid from an infected person enters another person's body via needle-sticks, human bites, cuts, abrasions, or through mucous membranes. Any body fluid with blood is potentially infectious.
How long do blood borne pathogens live?
This is because certain bloodborne viruses can live for days outside the body and still cause infection. Hepatitis B virus can live in dried blood for up to a week . Hepatitis C virus can survive for up to four days.
