I’m heading back to India

In a few days, I’ll be traveling to India—my third visit in three years. India is a place where big challenges meet even bigger ambitions, and where innovation is transforming lives at an incredible scale. Every time I’m there, I see firsthand how much progress is being made in public health, agriculture, and technology. And I come away with new ideas, because India is full of smart, ambitious people tackling some of the world’s hardest problems in creative ways.

This visit will also be significant because—as we mark our 25^th anniversary—the Gates Foundation’s Board of Trustees is meeting in the Global South for the first time. India is the right place for this milestone. The foundation has been working in the country for more than two decades, partnering with the government, researchers, and entrepreneurs to improve health and development. Today, India is home to some of the most impactful programs we’ve contributed to, from disease eradication and sanitation to women’s empowerment and digital financial services. This trip will give me a chance to see what’s working, what’s changing, and what’s next—for India and the foundation.

India’s track record in public health shows what’s possible. When I visited in 2011, it was one of the last places in the world still fighting polio. But that year, after relentless effort, India recorded its last case—and it’s remained polio-free ever since. Avahan, the HIV prevention program launched by the Gates Foundation two decades ago, is another success story. It pioneered a community-led approach to reduce infection rates that complemented the government’s efforts in high-prevalence states; eventually, management of the program transitioned to the Indian government, becoming part of the country’s broader health strategy.

That same model—leveraging local leadership, innovative solutions and data-driven insights—is now driving India’s fight against tuberculosis. The country has the world’s highest TB burden, but its investment in new diagnostics, AI-powered detection tools, and improved treatment strategies is accelerating progress toward elimination.

India’s success in childhood immunization is another reason I’m eager to return and learn more. Over the past several years, the country has scaled up routine vaccination programs, ensuring every major childhood vaccine is available. It has also used digital dashboards to track vaccine coverage, monitor cold storage, and improve maternal and child healthcare. These efforts have helped drive down mortality rates and create a stronger health system that can respond to new challenges.

India’s global health leadership is also transforming how the country approaches diagnostics and treatment for infectious diseases. As a result, it’s become a leader in low-cost vaccine manufacturing, ensuring that life-saving vaccines are available around the world. Indian companies are also tackling another critical challenge: making diagnostics more affordable. One effort I’m following closely is the push to make a saliva-based TB test for under $2, which could help millions of people in India and globally detect the disease earlier and get treatment faster.

Beyond health, India is also at the forefront of digital transformation. I’ve written before about how digital public infrastructure (DPI)—like Aadhaar and India’s digital payments system—has made it easier for millions of people to access banking, healthcare, and government services. Now, India is using AI-powered DPI tools to help rural health workers improve early disease detection, optimize pregnancy care, and manage patient data more effectively.

AI is also transforming agriculture across the country. When I was in Odisha last year, I saw farmers using AI-powered tools to predict weather patterns, choose crops, and reduce disease risks. I’m looking forward to seeing how much better those tools have gotten in the short time since.

What makes India’s progress so transformative, though, is that it doesn’t just benefit India. During India’s G20 Presidency in 2023, Prime Minister Modi declared his intent to make Indian innovations and know-how available to solve development problems globally. And that’s exactly what is happening. The solutions being developed there, from vaccine manufacturing to AI-powered diagnostics, are being shared with the world. Indian companies are making TB tests that could be game-changing across Africa. They’re developing AI models that could help farmers across Asia. And they’re proving that digital technology can make healthcare work better for everyone, especially the most vulnerable.

At the Gates Foundation, we tackle tough problems by working in close partnership with the people and governments most affected by them. India has been an incredible partner in this work because of the country’s deep expertise and willingness to develop and scale new ideas. The challenges remain: eliminating TB, improving nutrition, expanding access to AI-driven health and development services. But India has shown time and again that progress happens when innovation, local leadership, and investment come together.

That’s why I’m so excited for this trip. I’ll be meeting with government leaders, scientists, and philanthropists who are shaping the future of health and development in India. I’ll be visiting innovators who are working on solutions that could help people in India and around the world. And I’ll get to see how the foundation’s work fits into this bigger story—and how we can continue to support Indian-led efforts to improve lives.

I always leave India inspired. I know this trip will be no different.
