BBPs, or Blood-Borne Pathogens, are tiny microorganisms that can be transmitted through bodily fluids like blood, sweat, and saliva.
These pathogens can be extremely resilient and can survive outside of a host for extended periods.
They can be found in the blood of individuals with various infections, including HIV, hepatitis B, and hepatitis C.
BBPs can be transmitted through needlestick injuries, cuts or scrapes from contaminated sharp objects, or even through unprotected sex.
In fact, the Centers for Disease Control and Prevention (CDC) reports that over 5 million workers in the United States are at risk of exposure to BBPs on the job.
Transmission risks are heightened when proper protocols are not followed, such as not wearing personal protective equipment (PPE) or not disposing of contaminated materials correctly.

What are BBPs?
Bloodborne pathogens, or BBPs, are infectious microorganisms in human blood and other body fluids that can cause diseases. They're a serious concern for healthcare workers, who are at increased risk of exposure due to their work involving direct contact with blood and body fluids.
The Hepatitis B virus, Hepatitis C virus, and Human Immunodeficiency Virus (HIV) are all examples of BBPs. These diseases can be life-threatening and have serious consequences.
BBPs can be found in human blood, as well as other body fluids like saliva, semen, and vaginal fluids. They can also be present in other potentially infectious materials, or OPIM, which isn't specified in these examples.
Healthcare workers need to be aware of the risks and take preventive measures to minimize exposure to BBPs. This includes using personal protective equipment, following proper hygiene procedures, and disposing of contaminated materials safely.
BBPs can be transmitted through direct contact with infected blood or body fluids, as well as through needlesticks or other sharps injuries. It's crucial to take precautions to avoid these types of incidents.

Exposure Routes
Healthcare workers have the highest risk of exposure to bloodborne pathogens (BBPs), and it's crucial for them to have access to training and resources to prevent exposure as much as possible.

Needlestick injuries are a significant concern for occupational exposure, and they can occur when needles that have been used on an infected person accidentally puncture the skin of another person.
Cuts and abrasions from contaminated sharp objects, such as scalpels or broken glass, can also transmit BBPs if they cut or puncture the skin.
Splash exposure can happen if infected blood or body fluids splash into the mucous membranes of the eyes, nose, or mouth.
Direct contact with blood, body fluids, or contaminated surfaces can also transmit BBPs, especially if the worker has non-intact skin or open wounds.
Aerosol exposure can occur in procedures such as dental work or certain laboratory tasks, where aerosols containing blood or other potentially infectious materials (OPIM) may be generated.
Here are some common ways BBPs can be transmitted:
- Accidental cuts with contaminated sharp materials
- Needlestick injuries
- Sharp objects, such as scalpels or broken glass
- Contact with mucous membranes or broken skin
- Sharing of needles
- Unprotected sex
- High-risk behaviors, such as multiple sexual partners or having an existing STI
Risk of Transmission
BBPs can be transmitted through various routes, which include accidental cuts with contaminated sharp materials, needlestick injuries, and contact with mucous membranes or broken skin.
Needlestick injuries are a significant concern for healthcare workers, who are at risk of BBP transmission through accidental punctures with contaminated needles. This type of injury highlights the need for preventive measures and regulations to protect healthcare workers.
Sharp objects like scalpels or broken glass contaminated with infected blood can also cause transmission if they cut or puncture the skin. This is why proper handling and disposal of sharp objects are crucial in preventing BBP transmission.
BBPs can enter the body through the mucous membranes of the eyes, nose, and mouth, which can happen if infected blood or body fluids splash into these areas. This type of transmission can occur during procedures where blood or body fluids might splash, such as surgeries or when handling blood samples.
To prevent such transmissions, using protective gear such as face shields, goggles, and masks can help create a barrier between the fluids and mucous membranes. This is especially important for healthcare workers who are at risk during procedures that involve blood or body fluids.
Here are some high-risk behaviors that increase the risk of BBP transmission:
- Sharing needles for intravenous drug use
- Unprotected sex
- Multiple sexual partners
- Having an existing sexually transmitted infection (STI)
Precautions Against?
Precautions Against Bloodborne Pathogens (BBPs) are crucial to prevent exposure and infection. Conducting a hazard and risk assessment is the first step to determine who is potentially exposed to BBPs.
A written action plan, known as an Exposure Control Plan (ECP), should be established to control the hazards. This plan identifies workers subject to the plan and the job tasks that expose them to hazards.
Proper training is essential for exposed workers, covering topics such as H&S regulations, identifying hazardous tasks, and proper hygiene practices. Training should also include information on available vaccines, their effectiveness, and availability.
The ECP should specify the control measures to be taken to minimize the risk, such as the use of Personal Protective Equipment (PPE) and proper hygiene practices. It's also important to specify the procedures to be taken if there is an exposure.
The following control measures should be taken to minimize the risk of exposure:
- The use of PPE and its limitations;
- Proper hygiene practices;
- The use and care of appropriate PPE and its limitations;
- The procedures to be used if there is an exposure incident.
Frequently Asked Questions
Are BBPs only present in blood?
No, BBPs are not only present in blood, but also in other bodily fluids such as semen, vaginal secretions, and fluids from various body cavities. This includes any fluid that may be contaminated with blood or is unidentified.
