Health and Epidemiological Challenges in India: Public Health Crisis and Worker Migration

India is home to about 16.5% of the world’s population, yet it bears a disproportionate share of the global disease burden. From infectious diseases that refuse to go away, to lifestyle-related chronic conditions that are rising fast, and a healthcare workforce stretched dangerously thin – the country faces a multi-layered public health crisis. Understanding these health and epidemiological challenges is essential for anyone studying sustainability, because the health of a population is deeply connected to its economic productivity, environmental resilience, and social progress.

Why population health is more than just medicine 🔗

Population health is not determined by hospitals and medicines alone. It is shaped by a wide range of factors – nutrition, education, access to clean water, sanitation, social environment, health behaviours, disease prevention efforts, and the availability of healthcare services. A child’s health outcomes, for instance, depend as much on whether her family has access to nutritious food and clean drinking water as on whether there is a clinic nearby.

This complexity means that addressing India’s health challenges requires an interdisciplinary approach. Doctors, epidemiologists, nutritionists, urban planners, educators, and policymakers all have a role to play. A siloed approach – where the health ministry works in isolation from agriculture, education, or urban development – simply cannot work for a country as large and diverse as India.

According to research published in the Indian Journal of Community Medicine, India faces what experts call a “triple burden of disease” – the unfinished agenda of infectious diseases, the growing challenge of non-communicable diseases linked to lifestyle changes, and the constant threat of new pathogens causing epidemics and pandemics. This triple burden makes India’s health landscape one of the most complex in the world.

Understanding India’s disease burden 🔗

The National Commission on Macroeconomics and Health (2005) classified India’s health conditions into four broad categories: communicable diseases, maternal and child health conditions, non-communicable diseases (NCDs), and accidents and injuries. Each of these categories carries enormous weight in India’s overall disease profile.

Communicable diseases: progress, but not enough 🔗

India has made significant progress in tackling certain infectious diseases. Diseases like polio, guinea worm, yaws, and neonatal tetanus have been eliminated. Leprosy elimination has also advanced considerably. However, communicable diseases are far from conquered. HIV/AIDS, tuberculosis, and drug-resistant malaria continue to pose serious challenges. Recent estimates indicate approximately 2.45 million Indians live with HIV, reflecting a 0.36% prevalence rate in the general population.

Vector-borne diseases remain a persistent concern. As reported in Nature, India has achieved notable reductions in neglected tropical diseases – kala-azar cases, for example, fell from over 9,000 in 2014 to just 429 in 2025. But experts caution that these gains remain fragile, particularly in urban informal settlements and remote rural areas where surveillance is weakest.

Antimicrobial resistance – where bacteria and other pathogens become resistant to drugs – is another growing threat that complicates the treatment of infectious diseases across the country.

The rise of non-communicable diseases 🔗

While infectious diseases remain a challenge, NCDs have rapidly become the leading cause of death in India. The World Health Organization estimates that nearly 65% of all deaths in India are now attributable to NCDs, a dramatic rise from around 37% in 1990. Heart disease, diabetes, cancer, and chronic respiratory illnesses account for the bulk of these deaths.

This shift is driven by several factors: urbanisation, changing diets (more processed food, less physical activity), rising stress levels, air pollution, and the influence of advertising on consumption habits. A review published in Cureus highlights that NCD risk factors such as tobacco use, unhealthy diets, and physical inactivity are widespread across demographic groups, with notable disparities between urban and rural populations.

India faces a troubling epidemiological paradox: high rates of poverty-related diseases like tuberculosis and undernutrition coexist with rapidly rising lifestyle diseases like cardiovascular conditions and diabetes. The poorest communities often bear the heaviest burden of both.

Accidents and injuries 🔗

The fourth category – accidents and injuries – is often overlooked in public health discussions but contributes significantly to India’s disease burden. Road injuries, suicides, and falls are among the leading causes. According to the India State-Level Disease Burden Initiative, road injuries were the eighth leading cause of death in India, and injuries as a whole have increased in contribution to the total disease burden across most states since 1990.

India’s public health policy challenges 🔗

Despite these mounting health challenges, India’s political commitment to public health has historically been low. For decades, public health spending remained below 1% of GDP – far lower than the global average and well below what peer nations invested. Even decades after independence, public health continued to be treated as a low-priority area of governance.

The situation has improved somewhat in recent years. According to India’s Economic Survey, the share of government health expenditure in total health spending increased from 29% in FY15 to 48% in FY22, and the government’s health expenditure as a share of GDP rose from about 1.13% in FY15 to 1.84% in FY22. Still, this remains far short of the National Health Policy 2017 target of 2.5% of GDP.

A critical analysis published in the Indian Journal of Community Medicine found that India’s public health spending increased only from 0.9% to 1.6% of GDP in the five years following the 2017 policy – a modest gain given the ambitious target. India’s health expenditure of roughly 1.6% of GDP is significantly lower than the 7.6% average for OECD countries and even the 3.6% average for BRICS nations.

The consequence of this underspending is that out-of-pocket expenditure remains very high, pushing millions of families into poverty when a member falls seriously ill. While out-of-pocket spending as a share of total health expenditure has declined (from 64.2% in FY14 to 48.2% in FY19), it remains among the highest in the world.

Another structural issue is that India’s healthcare spending has been skewed heavily towards curative care, with inadequate investment in preventive and promotive health measures. This is a critical gap, because most NCDs are preventable through lifestyle changes, early screening, and community-level health education.

The health workforce crisis 🔗

No health system can function without enough trained professionals to run it. India faces a severe shortage of health workers – and the problem is most acute in rural and remote areas, where the majority of the population lives.

Shortage and maldistribution 🔗

According to a scoping review published in BMC Public Health, India suffers from both an overall deficit and a deeply unequal distribution of health workers. There are low numbers of qualified professionals overall, a high presence of unqualified practitioners (particularly in rural areas), and stark differences in doctor availability between cities and villages. Urban areas have nearly six times more doctors than rural areas.

India’s doctor-to-population ratio, when factoring in 80% availability of registered allopathic doctors along with AYUSH practitioners, is approximately 1:834. But this national figure masks severe regional imbalances – some states and districts have dangerously few health professionals available.

Migration of health workers 🔗

The shortage is made worse by the migration of doctors and nurses, both from rural to urban areas within India and from India to wealthier countries. Government figures indicate that approximately 60,000 India-trained doctors work outside the country, including nearly 9,000 in Canada alone. India has effectively trained 2% of Canada’s physician workforce and 5% of that of the US and UK, according to a report published in the Canadian Medical Association Journal.

Within India, the pull factors are clear: higher income, better working conditions, professional recognition, and career advancement opportunities. For health workers in rural areas, the push factors include poor infrastructure, professional isolation, lack of career growth, and challenging living conditions.

Impact on programmes like the National Rural Health Mission 🔗

The National Rural Health Mission (NRHM), launched in 2005, was designed to address rural health disparities through increased staffing, new infrastructure, and community health worker programmes like the ASHA (Accredited Social Health Activist) initiative. About 700,000 female community health workers were trained under this programme to provide basic first-contact healthcare and encourage families to seek maternal and child health services.

However, the NRHM has struggled to meet its staffing goals. As documented in the Bulletin of the World Health Organization, the availability of doctors and nurses in rural India is limited by a lack of training colleges in states with the greatest need, as well as the reluctance of urban-trained professionals to work in rural settings. Various strategies – compulsory rural service bonds, financial incentives, rotational postings, and contractual appointments – have been tried with mixed results.

Competing approaches to healthcare in India 🔗

India’s approach to public health has been shaped by two fundamentally different philosophies that emerged around the time of independence.

The Gandhian approach: community-centred and preventive 🔗

The first approach was rooted in Mahatma Gandhi’s vision – a bottom-up, rural-oriented model that prioritised community development. This perspective emphasised preventive care: clean water, environmental sanitation, nutrition, and grassroots health education. The idea was that health begins in the village, not in the hospital. Gandhi’s vision placed the community at the centre and saw health as inseparable from broader development – clean environments, self-reliant villages, and empowered local governance.

The Nehruvian approach: technology-driven and top-down 🔗

The second approach, championed by Jawaharlal Nehru, favoured rapid modernisation through science and technology. This top-down model emphasised building hospitals, medical colleges, and a state-level curative infrastructure. It also embraced family planning through new technologies as a means to control population growth. Over time, this approach resulted in an extensive network of public health facilities – primary health centres, community health centres, and district hospitals – across the country.

The tension between the two 🔗

In practice, the Nehruvian approach dominated post-independence health policy, resulting in significant investment in curative infrastructure but relatively less attention to preventive and community-level health initiatives. This imbalance continues to shape India’s health system today. The country has a large hospital network, but its primary and preventive care systems remain underdeveloped. Community health workers exist (like ASHAs), but they often lack adequate training, pay, and support.

Many public health experts argue that India needs a blend of both approaches – strong hospital infrastructure backed by robust primary care, community engagement, and preventive health programmes. The National Health Policy 2017 acknowledged this by calling for a shift from reactive curative care to proactive preventive and promotive healthcare, but implementation remains a challenge.

The epidemiological transition and its consequences 🔗

India is undergoing a rapid epidemiological transition – a shift in the pattern of diseases from primarily infectious to primarily chronic and lifestyle-related conditions. This transition is fuelled by urbanisation, globalisation, changing dietary habits, environmental degradation (especially air pollution), and demographic ageing.

According to a study published in Discover Public Health, India is currently in a “high-middle” epidemiological transition state. However, the pace of transition varies enormously across states – from highly transitioned states like Kerala to states like Uttar Pradesh where infectious diseases still dominate. The study found that the lag between states can be a decade or more, highlighting the need for region-specific health strategies rather than one-size-fits-all national policies.

This uneven transition means India must simultaneously fight two battles: finishing the unfinished agenda on infectious diseases while building capacity to handle the growing NCD burden. For the poorest and most marginalised communities, this double burden is especially devastating – they face higher risk for both communicable and non-communicable diseases, and are least equipped to cope with the financial consequences of illness.

Looking ahead: what needs to change 🔗

Addressing India’s health and epidemiological challenges requires action on multiple fronts. Increased public health spending is essential, but so is smarter allocation – directing more resources to preventive care, primary health centres, and community health programmes rather than concentrating investment in urban tertiary hospitals.

Retaining health workers in rural areas demands better incentives, improved working conditions, and training institutions located in underserved states rather than just metropolitan cities. Tackling the NCD crisis requires population-level interventions: regulating unhealthy food marketing, creating spaces for physical activity, reducing air pollution, and implementing systematic screening at the primary care level.

Above all, India needs to treat health as a fundamental input to sustainable development – not as a cost to be minimised but as an investment that pays dividends in human productivity, social equity, and national resilience.

What do you think? Given that India faces both poverty-related and lifestyle-related diseases simultaneously, should the country prioritise preventive community health over curative hospital infrastructure – or is there a more effective way to balance the two? How can India retain more health professionals in rural areas without restricting their career mobility?
