What are pathogens?

Pathogens are defined as infectious organisms that can cause disease in their hosts. This category includes a variety of organisms such as viruses, bacteria, fungi, and parasites. Understanding what constitutes a pathogen is essential in emergency care and public health, as it helps responders recognize the potential risks of infection in various scenarios.

The mention of infectious organisms underscores the critical role that viruses and bacteria play in disease transmission and the importance of proper protective measures. Emergency medical technicians (EMTs) must be aware of these organisms to prevent the spread of infection and to take the necessary precautions when dealing with patients who may be infected. The distinction of pathogens from other terms like chemicals or protective equipment highlights their unique role in healthcare settings, particularly regarding infection control and the treatment of communicable diseases.
