To be honest, I wouldn't say that lockdown is the sole reason of America's state now, but on the other hand, I'm quite in agreement with Khadeer that lockdown is probably the best way to check the spread of coronavirus in India. In a country like ours, with 1.3 billion people, more than half of the population illiterate, you can't expect to spread awareness about the disease and hope that people will obey. THEY WON'T!
On the 5th of April, our Prime Minister had made an appeal to the mass to light candles or even mobile torches at 9PM for 9 minutes to symbolize Indian unity and thank the healthcare staff who are working for us even at the cost of risking their own lives.
Wait ... the story doesn't end peacefully with everyone doing exactly that. Come on man, it's India ... We're always got to be special. There were "idiots" who deliberately lit fire torches and took a procession on the streets, shouting slogans like 'Go Corona go!', 'Corona go back!'. And ... You expect these _______ (I've put a blank please replace the word you find "worthy" for them, I'm out of vocabulary), to obey.
Here, unless lockdown is enforced and the police beats the sh*t out of people for breaking lockdown, there's not much that gonna happen.
My point is, in a situation like ours, lockdown is the best possible solution you could think of, and that too "enforced".
