👉 An infection is a condition where pathogens, such as bacteria, viruses, fungi, or parasites, invade and multiply within the body, causing damage to tissues and organs. This invasion disrupts normal bodily functions, leading to symptoms like fever, inflammation, pain, and swelling. When the immune system detects these foreign invaders, it mounts a response to eliminate them, often involving white blood cells and other immune components. However, if the infection is severe or the body's defenses are compromised, it can result in systemic illness, potentially leading to complications or even life-threatening conditions. Understanding infections is crucial for effective diagnosis and treatment, which may include antibiotics for bacterial infections, antiviral medications for viruses, antifungal treatments for fungi, and supportive care to bolster the immune system.
