Kajodi was a powerful image. A lonely figure, the vast emptiness of the Noida-Greater Noida Expressway and the horizon dotted with high-rise buildings. In the aftermath of the national lockdown announced on March 24, the 90-year-old was trying to walk from Delhi-NCR to her village in Rajasthan, some 400 km away. The image infuriated me. Then it depressed me. Trained as a scientist—a biochemist and virologist to be exact—I was in demand for my views on the coronavirus outbreak. Relying on public health principles, I was advocating social distancing and a lockdown…. But wasn’t I being completely blinkered by the science, and not paying attention to the “public” in public health? Indeed, I was…and I was angry with myself.
