The world’s second-largest country has gone into lockdown as India shuts down its massive train system Monday and puts curfews in place to stop the spread of coronavirus.

Indian Prime Minister Narendra Modi announced Tuesday that, “to save India,” the entire country is going into lockdown for 21 days, with every citizen banned from leaving home. A day earlier, Modi said people still were not taking an existing lockdown seriously and called for states to follow the preventive measures issued by the federal government to contain the virus.

“Please save yourself, save your family, follow the instructions seriously,” Modi said Monday.

INDIA STAMPS PEOPLE WITH END OF QUARANTINE DATE IN ATTEMPT TO TACKLE CORONAVIRUS

As of Tuesday morning, India had 469 confirmed COVID-19 cases and 10 deaths, according to a tally by Johns Hopkins University. Of all the cases reported in the country, at least 40 people have recovered from the virus, according to the tally.

Many of the coronavirus cases in India have been linked to foreign travel, but community spread of the disease is considered inevitable. Tens of millions live in dense urban areas with irregular access to clean water.

International flights were suspended at least until the end of March, while domestic air services also came to a halt. Streets around the capital of New Delhi were empty as residents stayed home. Officials have warned of strict legal action for those who don’t follow the rules.

Modi’s call for a 14-hour voluntary curfew on Sunday was the first nationwide effort at social distancing.

It was followed by suspending train services as thousands of migrant workers, suddenly out of work, were attempting to return to their villages, threatening to spread the virus outside major cities.
