infiltracija

Infiltracija is a term used in various fields to describe the process of something gradually entering or penetrating a substance, area, or organization. In medicine, it refers to the spread of disease, infection, or abnormal cells into surrounding tissues. For example, a cancerous tumor can infiltrate nearby organs, or an infection can infiltrate the bloodstream. Infiltration can also describe the movement of fluids, such as water infiltrating soil after rain or a local anesthetic infiltrating tissue before a medical procedure.

In a military or espionage context, infiltration involves secretly entering enemy territory or a target organization to gather intelligence, conduct sabotage, or carry out other covert operations. This often requires careful planning, disguise, and the ability to blend in with the surrounding environment or group. The infiltrator's goal is to remain undetected while achieving their objectives.

In urban planning and environmental science, infiltration refers to the process by which water penetrates the surface of the ground. This is a crucial aspect of the water cycle, as it replenishes groundwater reserves and can help reduce surface runoff, which can cause erosion and flooding. The rate of infiltration depends on factors such as soil type, vegetation cover, and the intensity of rainfall. Infiltration can also be a negative phenomenon, such as when water infiltrates a building's foundation, potentially causing structural damage or mold growth. The term emphasizes a slow, often unobserved, penetration.
