The Phases of Public Health Development in India: From Ancient Civilizations to Modern Reforms

Public health in India isn’t a recent invention-it stretches back over 5,000 years to the planned cities of the Indus Valley, where engineers built drainage systems centuries ahead of their time. From the holistic wisdom of Ayurveda to the colonial-era sanitary reforms and the bold promise of “Health for All by 2000,” every era added a new layer to how communities approached disease, hygiene, and wellbeing. Understanding these phases isn’t just an academic exercise; it explains why our healthcare system looks the way it does today.

Ancient contributions to public health 🔗

Long before the term “public health” existed, ancient Indian societies were already practicing it. The earliest evidence comes from the Indus Valley Civilisation, which flourished between 3300 and 1300 BCE across present-day Pakistan and northwest India. What archaeologists uncovered at Mohenjo-daro, Harappa, Dholavira, and Lothal reshaped our understanding of early civic planning.

The Indus Valley sanitation system 🔗

The urban centres of the Indus Valley featured what is widely considered the world’s first urban sanitation system. Almost every house had a private bathing area, with wastewater carried through covered terracotta pipes into a network of brick-lined public drains running along the streets. These drains had inspection points for maintenance, and waste eventually fed into soak pits that were periodically emptied-possibly even reused as fertiliser.

Mohenjo-daro alone had more than 700 wells serving its residents, alongside the famous Great Bath, an early example of a public water tank measuring roughly 12 by 7 metres. As one archaeological assessment put it, the level of public hygiene in these cities was unparalleled in the ancient world. European cities, by comparison, didn’t achieve a similar level of urban sanitation until the 19th century. This was public health engineering at its most foundational: clean water in, dirty water out, all without anyone yet understanding germ theory.

The emergence of Ayurveda 🔗

While the Indus Valley managed environmental health, the Vedic period gave India a systematic medical philosophy. Ayurveda, often translated as “the science of life,” developed around concepts of balance between the body, mind, and environment. Its two foundational texts-the Charaka Samhita and the Sushruta Samhita-remain reference points for traditional medicine today.

Charaka, who flourished between the 2nd century BCE and 2nd century CE, presented Ayurveda as a comprehensive system with both preventive and curative aims. He defined the objective of medicine as twofold: preserving the health of the healthy and combating disease in the sick. Sushruta, often called the father of surgery, documented surgical procedures, anatomical dissection techniques, and treatments for fractures in the Sushruta Samhita. Together, these texts emphasised diet, lifestyle, hygiene, environmental harmony, and the ethical duties of physicians-elements we now recognise as central to modern public health.

Distinct phases of public health development (1880-2000) 🔗

Modern public health, as a structured discipline, evolved through four widely recognised phases. These phases reflect changing scientific understanding, shifting political priorities, and the gradual realisation that health is shaped by far more than just medicine.

1. The disease control phase (1880-1920) 🔗

The late 19th century was dominated by sanitary legislation rather than targeted disease control. Public health authorities focused on improving the physical environment-water supply, sewage disposal, housing, and waste management. There was little technical knowledge of specific pathogens at the start of this period, so interventions were broad and environmental rather than disease-specific.

In colonial India, this phase had a distinct character. British administrators concentrated efforts on protecting their own troops and civilian officials from cholera, plague, and malaria-diseases that threatened the empire’s stability. The number of public hospitals and dispensaries rose from about 1,200 in 1880 to roughly 2,500 by 1902, although access remained heavily skewed toward urban elites and the British. Pioneers like Ronald Ross, who identified the malaria parasite’s transmission cycle in Secunderabad, and Waldemar Haffkine, who developed vaccines against cholera and plague, conducted groundbreaking research during this period. The Epidemic Diseases Act of 1897-still occasionally invoked today-was a product of this era.

2. The health promotion phase (1920-1960) 🔗

By the early 20th century, public health thinkers realised that controlling the environment wasn’t enough; the individual citizen had been neglected. A new concept-health promotion-began to take shape. The state accepted a more direct responsibility for the health of individuals, not just communities.

This phase saw the emergence of organised services: maternal and child health programmes, school health services, industrial health, mental health, and rehabilitation services. In India, this phase coincided with major institutional milestones. The All India Institute of Hygiene and Public Health was established in Kolkata in December 1932 with support from the Rockefeller Foundation, becoming the oldest school of public health in southeast Asia. The first Rural Health Training Centre was set up at Singur near Calcutta in 1939.

The defining moment, however, came with the Bhore Committee, formally known as the Health Survey and Development Committee. Appointed in 1943 under Sir Joseph Bhore, it submitted its landmark report in 1946. Its recommendations laid the blueprint for independent India’s health system: integration of preventive and curative services at all administrative levels, and the establishment of Primary Health Centres (PHCs) serving populations of 40,000 in the short term, with a more ambitious long-term plan of primary health units with 75-bed hospitals for every 10,000 to 20,000 people.

3. The social engineering phase (1960-1980) 🔗

Post-independence, the epidemiological landscape began to shift. Communicable diseases were slowly being brought under control through immunisation and antibiotics, but new challenges emerged-chronic diseases, accidents, and lifestyle-related conditions. Public health expanded to address what we now call social determinants of health: poverty, illiteracy, gender inequality, occupational hazards, and unsafe environments.

This phase recognised that disease was not just a biological event but a social one. Interventions therefore expanded beyond clinics into nutrition programmes, family planning campaigns, water and sanitation schemes, and behaviour-change communication. Several committees followed up on Bhore’s framework during these decades-the Mudaliar Committee (1961), the Chadah Committee (1963), the Mukerji Committee (1965), and the Kartar Singh Committee (1973)-each refining the structure of India’s primary healthcare delivery. The Srivastava Committee in 1975 explicitly recommended creating a cadre of community health workers, an idea that eventually shaped programmes like ASHA decades later.

4. The ‘Health for All’ phase (1981-2000) 🔗

The fourth phase was triggered by a global event. In September 1978, the World Health Organization and UNICEF convened the International Conference on Primary Health Care at Alma-Ata in the Soviet Union. The resulting declaration committed member nations to achieving an acceptable level of health for all the people of the world by the year 2000, with primary healthcare as the chosen strategy.

India was a signatory. The Alma-Ata Declaration fundamentally reframed health as a fundamental human right and a key social goal, and it explicitly linked health to broader socio-economic development. This was the philosophical engine behind the next major Indian policy.

Health for all by 2000 and the National Health Policy of 1983 🔗

Thirty-six years after independence, India formulated its first comprehensive health policy. The National Health Policy of 1983 was the country’s formal response to the Alma-Ata commitment.

What the policy aimed to do 🔗

The NHP 1983 began by affirming the state’s constitutional responsibility for the health of its citizens. It noted that despite three decades of independence, the demographic and health picture was a cause for serious concern: rapid population growth was straining services, maternal and infant mortality remained extremely high, and children under five accounted for roughly one-third of all deaths. Infant mortality at the time was estimated at around 129 per thousand live births.

The policy committed India to “Health for All by the Year 2000 AD” through the universal provision of comprehensive primary healthcare services within an integrated planning framework. Its core priorities included:

nutrition and prevention of food adulteration; maintenance of drug quality; safe water supply and sanitation; environmental protection; immunisation; maternal and child health services; school health; and occupational health. It also formalised India’s three-tier healthcare delivery system: Primary Health Centres and sub-centres at the base, secondary-level community health centres and district hospitals in the middle, and tertiary teaching hospitals at the top.

Decentralisation and community participation 🔗

One of the most important features of the 1983 policy was its emphasis on decentralisation. Instead of pushing all care into urban hospitals, the policy directed resources toward dispersed, community-based primary care. It explicitly recognised medical pluralism, giving formal space to traditional systems like Ayurveda, Yoga, Unani, Siddha, and Homoeopathy (the AYUSH family). It also encouraged community participation through trained health volunteers and village-level health committees-an idea borrowed from the Bhore Committee but only seriously operationalised in this phase.

What it actually achieved-and where it fell short 🔗

The results were mixed. On the positive side, India achieved the complete eradication of smallpox, made strong gains against polio and leprosy, and dramatically expanded its network of Primary Health Centres and sub-centres between 1983 and 2000. Immunisation coverage rose substantially, life expectancy improved, and maternal and infant mortality fell, though not as fast as the policy hoped.

However, the ambitious goal of “Health for All by 2000” was not fully met. Rural-urban disparities persisted, the public system remained underfunded, and the policy’s preventive philosophy was gradually overshadowed by a more curative, hospital-based, medicalised approach. These shortcomings prompted the National Health Policy of 2002, and later the National Rural Health Mission (2005), the National Health Policy 2017, and Ayushman Bharat (2018)-each building on the structural foundation that 1983 had laid.

Why this history still matters 🔗

Every layer of this history is still visible in today’s healthcare system. The PHC you might pass on a rural road, the AYUSH clinic in a small town, the ASHA worker visiting expectant mothers, the smallpox-free certificates in your school textbook-each is a direct descendant of a specific phase. The Indus Valley reminds us that environmental engineering is health policy. Ayurveda reminds us that prevention is older than cure. The colonial sanitation phase reminds us that public health can be uneven and political. And the 1983 policy reminds us that ambitious goals, even when imperfectly achieved, set the trajectory for decades of progress.

What do you think? If India had achieved every goal of the 1983 “Health for All” policy on schedule, how different might the country’s response to recent public health challenges have looked? And which of the four phases of public health do you think most defines the system you experience today?
