Chapter at a Glance
- Health means complete physical, mental and social well-being, not merely the absence of disease. Loneliness, stress and a polluted neighbourhood damage health just as germs do.
- A symptom is what we feel — pain, tiredness, dizziness. A sign is what can be seen or measured — fever, rash, high blood pressure, swelling.
- Communicable diseases are caused by pathogens (bacteria, viruses, fungi, worms, protozoa) and spread by air, by contaminated food and water, by direct or indirect contact, and by vectors such as mosquitos and houseflies.
- Non-communicable diseases — diabetes, heart disease, cancer, asthma, and deficiency diseases such as scurvy, anaemia and goitre — are not caused by pathogens. They are linked to lifestyle, diet and environment, and today cause most deaths in India.
- Immunity is the body's natural ability to fight disease. A vaccine trains the immune system using dead, weakened or harmless parts of a germ, giving acquired immunity . Vaccines are preventive, never curative.
- Antibiotics kill bacteria only, because they attack parts of bacterial cells that human cells do not have. Using them when they are not needed, or stopping the dose halfway, breeds antibiotic resistance .
