Indian firefighters spray disinfectants as a preventive measure against the spread of the new coronavirus on a street in Gauhati, India, Wednesday, March 25, 2020. The world's largest democracy went under the world's biggest lockdown Wednesday, with India's 1.3 billion people ordered to stay home in a bid to stop the coronavirus pandemic from spreading and overwhelming its fragile health care system as it has done elsewhere. The new coronavirus causes mild or moderate symptoms for most people, but for some, especially older adults and people with existing health problems, it can cause more severe illness or death.
