History of Diseases in India: From Ancient Times to the Modern Era
Ancient India
Harappan Civilization and Public Health
- The Indus Valley Civilization (c. 3300–1300 BCE) showcased advanced urban planning, with well-laid-out drainage systems and water supply mechanisms.
- The presence of public baths and toilets suggests an early understanding of
Vedic and Post-Vedic Period
- The Atharvaveda (c. 1200–1000 BCE) includes hymns related to healing, disease diagnosis, and warding off illness through mantras and herbs.
- Diseases were believed to be caused by divine wrath or supernatural forces, but also due to imbalance of bodily elements (doshas: Vata, Pitta, Kapha).
Development of Ayurveda
- Ayurveda, the “Science of Life,” emerged as a codified medical system.
- Key texts:
- Charaka Samhita (Charaka): Focused on internal medicine (Kaya Chikitsa). It described over 2,000 medicinal substances and about 340 diseases.
- Sushruta Samhita (Sushruta): Emphasized surgery (Shalya Chikitsa), including cataract surgery, bone setting, and plastic surgery.
- These texts described illnesses such as:
- Jwara (fever)
- Kushta (skin diseases including leprosy)
- Rajayakshma (tuberculosis)
- Madhumeha (diabetes)
Classical and Early Medieval Period (600 BCE – 1200 CE)
Role of Universities
- Takshashila, Nalanda, and Vikramashila were major centres of medical learning.
- Students studied Ayurveda, surgery, pathology, anatomy, and pharmacology.
Buddhist and Jain Contributions
- Buddhist monasteries functioned as early hospitals (vihara-based healing).
- Jainism advocated for strict non-violence (Ahimsa) and dietary practices that minimized disease risk.
- Public health practices included cleanliness, quarantine, and care of the sick in monastic settings.
Disease Management
- Emphasis on diet, lifestyle (dinacharya and ritucharya), and preventive medicine.
- Seasonal regimens and detoxification therapies (e.g., Panchakarma) were recommended.
Medieval Period and Sultanate Era (1200–1526 CE)
Arrival of Unani Medicine
- With the advent of Muslim rule, Unani Tibb (Greek-Arabic medicine) was introduced to India.
- Based on the balance of four humors: blood, phlegm, yellow bile, and black bile.
- Practiced by Hakims, it focused on pulse reading, herbal remedies, and diet therapy.
Medical Infrastructure
- Establishment of Dar-ul-Shifa (government hospitals) in major cities.
- Health care was a part of royal patronage — public access to medicines and physicians increased.
Common Diseases
- Smallpox, cholera, dysentery, and plague-like illnesses were recorded in historical chronicles.
- Treatment largely based on traditional systems and empirical experience.
Mughal Period (1526–1857 CE)
Expansion of Medical Services
- Mughal emperors promoted both Ayurveda and Unani traditions.
- Royal dispensaries and hospitals were set up in Delhi, Agra, Lahore, and other cities.
- Notable physicians included Hakim Ali Gilani and Hakim Ajmal Khan.
Epidemics and Disease Response
- Recurrent outbreaks of smallpox led to early inoculation practices (variolation) in villages.
- Leprosy and tuberculosis were prevalent, and the sick were often socially ostracized.
- Unhygienic urbanization increased the frequency of waterborne diseases like cholera and dysentery.
British Colonial Period (1858–1947)
Major Epidemics
- Cholera Pandemics (1817–1923):
- Originated in Bengal and spread globally.
- Led to over 2 crore deaths across six waves.
- Plague Epidemic (1896–1910):
- Started in Bombay (Mumbai) and spread across India.
- Led to harsh Plague Acts and forced quarantines.
- Spanish Flu (1918–1919):
- Returned soldiers from WWI brought the flu.
- Estimated 12–17 million Indians died, making India the worst-hit country.
Colonial Public Health Measures
- Establishment of:
- Sanitary Commissioners
- Pasteur Institutes for vaccine production
- Municipal sanitation departments
- Introduction of vaccination programs for smallpox and cholera.
- Creation of Indian Medical Services (IMS), primarily to serve British officials.
