People power: How India is attempting to slow the coronavirus

Like many nations, India does not have enough kits to test most of its population for the new coronavirus. The country is instead relying on people power: thousands of health-care workers are fanning out across the country to trace and quarantine people who might have had contact with those with COVID-19. People are typically only tested if they develop symptoms.
Countries such as South Korea isolated infected people based on widespread testing, but some scientists say that India’s mass-surveillance approach could achieve a similar goal, and be relevant for other low- and middle-income countries facing kit shortages.
