👉 The clause "infection" refers to a condition where a pathogen, such as bacteria, viruses, fungi, or parasites, invades and takes control of a host's body, leading to illness or disease. This can occur when the body's natural defenses are overwhelmed or bypassed, allowing the pathogen to multiply and cause damage to tissues and organs. Infections can manifest in various ways, from mild symptoms like a cold to severe conditions such as sepsis or organ failure, depending on the type of pathogen and the host's immune response. Understanding infection is crucial for developing preventive measures, treatments, and vaccines to protect public health.
