What does the term 'infection' refer to in the context of body tissue?

The term 'infection' in the context of body tissue refers specifically to the contamination by harmful organisms, such as bacteria, viruses, fungi, or parasites, that invade the body. When these microorganisms enter the body and begin to multiply, they can disrupt normal bodily functions and lead to various symptoms and health issues. This is distinct from processes like healing or repair, which pertain to the body’s response to injury and involve the growth of healthy cells and tissues. Understanding this definition of infection is crucial for recognizing how to prevent and treat such conditions, especially in fields related to health and beauty, where maintaining a sterile environment is essential to prevent infections during procedures like manicure and pedicure treatments.
