Immunocompetent refers to an individual's immune system being fully functional and capable of responding effectively to pathogens, such as viruses and bacteria. This means that the body can recognize and mount an appropriate immune response, including the production of antibodies and activation of immune cells. Immunocompetence is crucial for maintaining overall health and preventing infections or diseases. In contrast, individuals who are immunocompromised have weakened immune systems, making them more susceptible to infections.
