An individual is considered immunocompromised when their immune system is weakened or not functioning properly. This condition can result from various factors, including certain medical treatments, such as chemotherapy, or underlying health issues like HIV/AIDS or autoimmune diseases. As a result, these individuals are more susceptible to infections and may have a harder time recovering from illnesses. People who are immunocompromised often need to take extra precautions to protect their health. This may include avoiding crowded places, practicing good hygiene, and receiving vaccinations to prevent infections. Healthcare providers may also recommend specific treatments or medications to help strengthen their immune response.
