Syndrome is a group of symptoms, signs, physical and physiological disturbances that are due to a common cause. AIDS is also a complex of diseases and symptoms which develop due to failure of the body to fight off even minor infections. HIV that causes AIDS damages immune system of the patient by destroying T₄ helper cells (T lymphocytes). As a result, even small cold leads to development of pneumonia, a slight gut infection leads to severe diarrhoea and blood loss, likewise skin rashes develop into ulcers.
Immune system is body defense system against various types of pathogens. It includes following components of blood-phagocytic cells, natural killer cells (NK cells), T-lymphocytes and B-lymphocytes. B-lymphocytes produce antibodies against antigens of pathogens and their toxins. Immune system keepsRead more
