India imposed a three-week long nationwide lockdown for its 1.3 billion people, the most far-reaching measure undertaken by any government to curb the spread of the Coronavirus Pandemic.“If we listen to the health experts, we know that 21 days are crucial to break the cycle of transmission,” Prime Minister Narendra Modi said in a televised address to the nation on Tuesday. “For a few days forget what it means to go out. Today’s decision of a nationwide lockdown draws a line outside your home.”The South Asian nation is struggling to contain the economic and health fallout from the outbreak that has so far infected 519 people in the country and killed 10. India could become the next global hotspot for virus cases, with experts warning containment measures that proved successful elsewhere in Asia may not work in the world’s second-most populous country. On Tuesday, Modi also allocated about $2 billion for additional health care measures.
