But, people go for life's essential needs and pick up virus spread. If governments are able to supply essential things at door steps at least for 15 to 20 days then they could contain the spread of covid18 somehow.
Government can do that but people have to move out for work and their jobs since not all the industries can allow work from home and hence they have to move out for work and the government should but probably could not afford the essentials for 20 days free of cost.
