A drone hovers over a befuddled elderly lady, almost stalking her. Speakers attached to the flying machine chime out a sing-song but commanding warning. “Grandma, do not go out without wearing a protective mask, and you better stay at home to be safe.” A photographer at a village in northern China’s Inner Mongolia Autonomous Region captures the rural woman’s encounter with ultra-modern technology—something in ample use in the country’s aggressive fight against the outbreak of an unknown strain of coronavirus that has no vaccine, no cure. Drones tennoying warnings and steps people should take to check the spread of the virus—checking body temperature and spraying disinfectant—in the early days of the outbreak was one of the examples of how the country pulled out all its state-of-the-art technological stops against the contagion.
