👉 Insertion of infection refers to the process by which pathogens, such as bacteria, viruses, fungi, or parasites, enter and begin to multiply within a host organism's body. This can occur through various routes, including inhalation, ingestion, direct contact, or vector-borne transmission. Once inside, these microorganisms can disrupt normal cellular functions, leading to tissue damage and inflammation. The immune system initially responds with an inflammatory reaction to contain and eliminate the invaders, but if the infection persists or is overwhelming, it can progress to a full-blown infection, characterized by symptoms like fever, swelling, and organ dysfunction. Effective treatment often requires addressing both the pathogen and the host's immune response to prevent further complications.
