Occupational Safety and Health Administration (OSHA) SLC Practice Exam

An exogenous infection is defined as:

1. A pathogen from within the body

2. A pathogen introduced from the outside environment

3. A virus that already exists in the body

4. A bacteria that cannot be transmitted

The correct answer is: A pathogen introduced from the outside environment

An exogenous infection refers to an infection that is caused by pathogens originating from outside the body. This can include bacteria, viruses, fungi, and parasites that are introduced into the body through various means, such as through breaks in the skin, inhalation, or ingestion. Understanding this concept is crucial in fields like occupational health and safety, where exposure to external pathogens can pose significant risks to workers, particularly in healthcare and laboratory settings. In contrast, infections caused by pathogens that are already present within the body are termed endogenous infections. Therefore, knowing that exogenous infections come from an external source distinguishes them from infections produced by the body's own microbial flora. This distinction is essential for implementing appropriate preventive measures to protect individuals in various occupational environments.
