👉 Infection, particularly from pathogens like bacteria, viruses, or parasites, occurs when these microorganisms breach the body's natural defenses and establish themselves within host tissues. This invasion can lead to a range of symptoms and health complications, from mild illnesses to severe diseases. The want for infection is driven by the body's innate need to eliminate foreign invaders that threaten its homeostasis and survival. However, when infections persist or overwhelm the immune system, they can cause significant damage, leading to conditions such as sepsis, pneumonia, or chronic illnesses. Preventing and treating infections is crucial for maintaining health and preventing the spread of diseases, highlighting the importance of hygiene, vaccination, and timely medical intervention.
