Candidemia is a bloodstream infection caused by the fungus Candida. It often occurs in individuals with weakened immune systems, such as those in hospitals or with chronic illnesses. Symptoms can include fever, chills, and low blood pressure, but some patients may not show any signs. Diagnosis typically involves blood cultures to identify the presence of Candida species. Treatment usually requires antifungal medications, and early intervention is crucial to prevent complications. In severe cases, it may lead to organ failure or death if not addressed promptly.
