Pathogen

Any agent capable of causing disease. The term pathogen is usually restricted to living agents, which include viruses, rickettsia, bacteria, fungi, yeasts, protozoa, helminths, and certain insect larval stages. See Disease

Pathogenicity is the ability of an organism to enter a host and cause disease. The degree of pathogenicity, that is, the comparative ability to cause disease, is known as virulence. The terms pathogenic and nonpathogenic refer to the relative virulence of the organism or its ability to cause disease under certain conditions. This ability depends not only upon the properties of the organism but also upon the ability of the host to defend itself (its immunity) and prevent injury. The concept of pathogenicity and virulence has no meaning without reference to a specific host. For example, gonococcus is capable of causing gonorrhea in humans but not in lower animals.

Bloodborne pathogens: pathogenic microorganisms that are present in human blood and cause disease in humans.
The purpose of the new OSHA Bloodborne Pathogens Standards is to enforce the concept of universal precautions and to create a safe workplace.[4,6-9] All blood and human body fluids, except urine, feces, and vomitus not visibly contaminated with blood or mixed with other body fluids, are considered to be potentially infectious.[7,9,12] The mandatory OSHA Standard ensures worker access to needed safety materials and equipment.
Another issue that has recently developed is the risk of the patient being exposed to the bloodborne pathogens of the physician.
This online course fulfills OSHA's initial and annual bloodborne pathogens training requirements for all body art professionals.
Health-care workers and first responders exposed to blood in the workplace are at risk for infection by bloodborne pathogens. However, their risk for acquiring HCV infection is low because HCV is not transmitted efficiently through occupational exposure [4-6].
Those who choose to violate the Bloodborne Pathogens Standard are at risk of acquiring any of the 20 diseases known to be transmitted by blood exposure.
Camps, and ultimately camp administrators, have a key responsibility in addressing problems of bloodborne pathogen contagion.
Careful adherence to these recommendations should minimize the risk of patient or health-care worker exposure to bloodborne pathogens during nuclear medicine procedures.
