👉 Infection refers to the invasion and multiplication of pathogenic microorganisms, such as bacteria, viruses, fungi, or parasites, within a host organism, leading to disease. This can occur when these invaders breach the body's natural defenses, often through breaches in the skin, mucous membranes, or other entry points. Once inside, pathogens can multiply rapidly, triggering an immune response that may cause symptoms ranging from mild discomfort to severe illness. Infections can be acute, lasting for a short period, or chronic, persisting over months or years. Common causes include poor hygiene, exposure to contaminated environments, and weakened immune systems. Treatment typically involves antibiotics for bacterial infections, antiviral medications for viral ones, antifungal agents for fungal infections, or antiparasitic drugs, depending on the specific pathogen. Understanding and managing infections is crucial for preventing complications and promoting recovery.
