👉 Indication refers to the clinical signs, symptoms, or test results that suggest the presence of an infection. Infection occurs when a pathogen, such as bacteria, viruses, fungi, or parasites, invades and multiplies within a host, disrupting normal bodily functions. The body's immune system responds by initiating an inflammatory response to combat the invader, leading to symptoms like fever, redness, swelling, and pain at the infection site. Diagnosis often involves identifying these signs and symptoms through physical examination, laboratory tests (e.g., blood cultures, urine analysis), or imaging studies. Understanding the ind:infection relationship is crucial for timely diagnosis and effective treatment to prevent complications and promote recovery.
