What is a pathogen?

A pathogen is defined as a microorganism capable of causing disease. This includes a variety of entities such as bacteria, viruses, fungi, and parasites that can invade the body and disrupt normal bodily functions, leading to illness. Understanding the role of pathogens is crucial in infection control, particularly in dental settings, where the transmission of these microorganisms can occur. Proper sterilization and disinfection practices help to minimize the risk posed by pathogens, protecting both patients and healthcare providers.
