The biggest lockdown in the world

Indian Prime Minister Narendra Modi has imposed a 21-day lockdown in an attempt to slow the coronavirus spread.

"There will be a total ban on venturing out of your homes," Modi told the country, which represents nearly a fifth of the world's population, in a televised address

Crowds quickly swamped stores in cities across the country, stripping shelves bare before the lockdown took affect. The BBC reports it is not clear how people will now buy food and other essentials. India has a relatively low number of reported cases so far -- just over 600 among its 1.3 billion people -- but the combination of extremely high population density and a weak public health system makes a serious outbreak a real risk.
