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 Tâ‚„ 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

Disease symptoms are evidences of presence of diseases. Symptoms are in the form of structural and functional changes in the body or body parts. They indicate that there is something wrong in the body, e.g., wound with pus, oedema, cough, cold, loose motions, pain in abdomem, headache, fever. HoweveRead more

They indicate that there is something wrong in the body, e.g., wound with pus, oedema, cough, cold, loose motions, pain in abdomem, headache, fever. However-symptoms do not give any exact cause of the disease. For instance, headache may be due to some dozen different diseases.

(a) For keeping good health, we should eat a balanced diet containing adequate (proportionate) amounts of all the essential nutrients such as carbohydrates, proteins, fats (lipids), vitamins, minerals, water and roughage. Unbalanced diet causes malnutrition. Proper nourishment maintains the health of all the body systems including the immune system.
(b) Health of an organism including human beings depend upon the surrounding environmental conditions.
Public Health Services ensure clean environment around our dwellings and protection from outbreak of diseases. They ensure removal of garbage, drainage and sewage services, proper drinking water, unadulterated food articles, vector and pest control, vaccination and other health care services. If these services are insufficient or faulty, the health of individual citizens is bound to be adversely affected despite taking the best balance food and keeping the best personal hygiene. It is because, infection is contracted from others and is connected with uncontaminated food.
(c) Stagnant water (of pools, ponds) is habitat of larvae of many types of mosquitoes. It is also source of many
water borne diseases. Therefore, stagnant water should not be present in and around human habitations.
(d) (i) Social equality and harmony are required for participating in one another’s joys and sorrows, helping the others and receiving help at the time of need. There should not be any sort of mistrust, worry and mistreatment of each other. This would make everybody in the community happy and healthy.
(ii) A proper nutrition is essential for good health. Poverty is the root cause of nutritional disorders (i.e., malnutrition and under nourishment) in our country. There should be proper earning in order to provide food to everyone in the family. For a good earning there should be opportunity for a proper job for which the bread earner has been trained. Therefore, a proper training for job, a good job and subsequently good economic conditions are needed to maintain health of the individuals.
