A localized disease is an infectious or neoplastic process that originates in and is confined to one organ system or general area in the body, [1] such as a sprained ankle, a boil on the hand, an abscess of finger.
Focal infection theory is the historical concept that many chronic diseases, including systemic and common ones, are caused by focal infections. In present medical consensus, a focal infection is a localized infection, often asymptomatic, that causes disease elsewhere in the host, but focal infections are fairly infrequent and limited to fairly uncommon diseases.

Odontogenic infection starts as localised infection and may remain localised to the region where it started, or spread into adjacent or distant areas. It is estimated that 90–95% of all orofacial infections originate from the teeth or their supporting structures and are the most common infections in the oral and maxilofacial region. [3]
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4] [7]This initial stage of sepsis is followed by suppression of the immune system. [8]

They are usually caused by a bacterial infection. [10] Often many different types of bacteria are involved in a single infection. [8] In many areas of the world, the most common bacteria present is methicillin-resistant Staphylococcus aureus. [1] Rarely, parasites can cause abscesses; this is more common in the developing world. [3]
Although a single injection of long-acting penicillin or other beta lactam antibiotic cures the disease and is widely available and the disease highly localised, many eradication campaigns ended in complacency and neglect; even in areas where transmission was successfully interrupted, re-introduction from infected areas occurred.
