Bacteremia is a medical condition characterized by the presence of bacteria in the bloodstream. This can occur due to infections in various parts of the body, such as the lungs, urinary tract, or skin. When bacteria enter the bloodstream, they can spread throughout the body, potentially leading to serious complications. Symptoms of bacteremia may include fever, chills, rapid heartbeat, and low blood pressure. Diagnosis typically involves blood cultures to identify the specific bacteria present. Treatment usually requires antibiotics to eliminate the infection and may involve hospitalization, especially in severe cases.
