👉 An infected fluid, often referred to as an abscess or hematoma, is a collection of pus and/or blood that forms within body tissues, typically due to an infection or injury. This fluid results from the body's immune response to pathogens or damaged cells, leading to inflammation and the accumulation of necrotic tissue. The pus contains white blood cells that fight infection, while the blood may contain hemoglobin from damaged vessels. These fluid collections can occur in various parts of the body, such as the skin, bones, or internal organs, and can be painful and sometimes indicative of an underlying infection that requires medical attention.
