Imunodeficenca
Imunodeficenca refers to a state where the body's immune system is weakened or not functioning properly, leaving it vulnerable to infections and diseases. This deficiency can be congenital, meaning it is present from birth, or acquired, developing later in life. Congenital immunodeficiencies, often called primary immunodeficiencies, are typically caused by genetic mutations that affect the development or function of immune cells. There are over 400 known primary immunodeficiency disorders, each with varying severity and symptoms. Acquired immunodeficiencies, or secondary immunodeficiencies, result from external factors that impair the immune system. Common causes include certain medical treatments like chemotherapy or radiation therapy, chronic illnesses such as HIV/AIDS, malnutrition, and the use of immunosuppressant drugs.
The symptoms of immunodeficiency can range from mild to severe and often include recurrent or persistent infections
