1-7. SIGNS AND SYMPTOMS OF INFECTION
Inflammation is a purposeful reaction of tissue to injury. If it develops in the absence of pathogens, it is called a sterile inflammation. When produced by pathogens, it is called septic.
a. Changes in Tissue Caused by Inflammation. The changes induced in infected tissues by inflammation consist of heat, redness, swelling, sensitivity, tenderness, and pain. In addition, red streaks radiating from the affected area may be present as well as pus formation, usually in the center of the infection. Malaise, headache, and fever may also be present.
b. Sepsis. If the infectious process cannot be localized in the wound area by the body's defenses, it eventually spreads so that a generalized septic condition or septicemia develops. This may result in shock that can lead to death.
