Infection

📖What is Infection?

Infection is the invasion and multiplication of disease-causing microorganisms, including bacteria, viruses, fungi, or parasites, within the tissues of the body, triggering an immune response that often produces characteristic signs of illness. Infections can be localized to a specific site, such as a wound or the urinary tract, or become systemic, spreading through the bloodstream to affect multiple organs, a serious condition known as sepsis. The severity of an infection depends on the type and virulence of the causative organism, the site involved, and the strength of the individual's immune system. Laboratory testing, including cultures, blood tests, and molecular assays, is essential to identify the specific causative organism and guide appropriate targeted treatment.
