Invasive candidiasis is a serious infection caused by the Candida fungus, which can enter the bloodstream and affect various organs. It often occurs in people with weakened immune systems, such as those in hospitals or with chronic illnesses. Symptoms may include fever, chills, and discomfort, but they can vary depending on the affected area. Diagnosis typically involves blood tests and cultures to identify the presence of Candida. Treatment usually requires antifungal medications, and early intervention is crucial for improving outcomes. Preventive measures, such as maintaining good hygiene and careful monitoring in high-risk patients, can help reduce the risk of infection.
