👉 Infection manifests as a visible or palpable alteration in the body's normal state, often appearing as redness, swelling, warmth, and pain at the affected site. Initially, the area may look inflamed, with increased blood flow causing the skin to appear flushed or erythematous. As the infection progresses, pus may accumulate, creating a characteristic pustular appearance, while surrounding tissues might swell and become tender to the touch. In more severe cases, such as abscesses, a visible pocket of pus can form, sometimes accompanied by fever, chills, and systemic symptoms like fatigue or malaise. The overall effect is a clear indication of the body's immune response to an invading pathogen, highlighting the intricate interplay between infection and the host's defense mechanisms.
