In this essay for Healthbeat, Dr. Jay Varma outlines how artificial intelligence can modernize disease prevention and treatment—supporting immunization systems, HIV/STI/TB programs, maternal health, and chronic disease care—while cautioning that privacy, equity, and oversight remain critical.
AI and the Future of Public Health
Public health agencies shoulder an immense responsibility: protecting populations through disease surveillance, vaccination, screening, and maternal-child health programs. Yet many agencies rely on outdated infrastructure—paper records, manual data entry, and fragmented information systems.
In his August 2025 guest essay for Healthbeat, Dr. Jay Varma argues that artificial intelligence could transform public health practice, if deployed carefully and equitably. AI can streamline logistics, expand access, and help professionals focus on tasks that require empathy and human judgment. But, as Dr. Varma emphasizes, it must be paired with funding, leadership, and safeguards.
Immunization: Closing Gaps and Preventing Waste
COVID-19 exposed weaknesses in U.S. vaccine systems: eligibility confusion, inventory shortages, and low uptake. AI can help integrate fragmented immunization records, identify missed vaccinations, and predict supply needs.
Dr. Varma highlights examples from DataKind and Gavi, where AI extracted vaccine histories from paper records and forecasted stock shortages, enabling outreach to unvaccinated children and smarter supply management. These tools reduce waste while ensuring vaccines reach those most at risk.
HIV, STI, and TB: Modernizing Legacy Systems
Despite biomedical advances, many STI and TB programs still rely on faxes and manual registries. AI-powered chatbots can answer patient questions, schedule appointments, and triage eligibility. Machine learning can spot clusters of new infections or gaps in prevention services.
For TB, AI-driven chest X-ray interpretation can outperform non-specialist clinicians, helping health departments triage faster and direct limited staff toward counseling, contact tracing, and patient support.
“AI won’t replace the human core of public health—but it can amplify capacity, helping staff reach more people with greater precision.” —Dr. Jay Varma
Maternal and Infant Health: Predicting Risks and Saving Lives
AI can support pregnant patients and new parents by personalizing health reminders, flagging risk factors, and monitoring symptoms postpartum—the period when complications are most likely.
In Rwanda, an AI system predicted high-risk pregnancies from routine prenatal data, helping midwives focus care where it was most urgently needed. Such tools could reduce maternal and infant mortality by targeting interventions more effectively.
Chronic Diseases: Reaching the Underserved
Chronic disease screening often misses those most at risk. AI can analyze health records and claims to identify overdue patients and power mobile screening units.
In India, a smartphone-based retinal scanner with AI support enabled non-specialist technicians to detect diabetic retinopathy in rural areas. Similar approaches could support cancer screening through AI-assisted mammogram or Pap smear interpretation, coupled with reminders and follow-up prompts.
The Cautions: Equity, Trust, and Oversight
Dr. Varma stresses that AI is not a panacea. Systems trained on incomplete or biased data can entrench inequities. Tools designed without community input may face rejection. And without open-source or affordable options, commercial AI systems may remain out of reach for public agencies.
To succeed, AI adoption must be guided by:
- Funding to modernize outdated data systems
- Leadership willing to innovate and take calculated risks
- Ethical and legal oversight to protect patient rights and prevent bias
A Balanced Vision
AI will not replace the human core of public health—empathy, trust, and community connection. Instead, it can amplify capacity, making it possible for fewer staff to serve more people with greater precision. Done right, AI has the potential to join the ranks of past public health breakthroughs—clean water, sanitation, vaccines, and antibiotics—as a tool that saves lives on a massive scale.
