2. Immunodeficiency Diseases and Infections

Immunodeficiency diseases occur when the immune system, which protects the body from infections, does not function properly. This can be due to genetic factors, infections (like HIV), or certain medications. Individuals with these diseases are more vulnerable to frequent and severe infections because their body struggles to fight off germs. Common symptoms may include recurrent illnesses, fatigue, and delayed recovery. Treatment focuses on managing infections and, in some cases, boosting the immune system through therapies or medications. Awareness and early diagnosis can significantly improve quality of life for those affected.
