The problem is that people aren't taking the precautionary measures seriously. People are still going out even though they aren't allowed because of the risk of contracting and spreading the virus. If government are less lenient to people like this and rule as an embodiment of law then they might discipline this people.
That's true we also must remember there are infected who are asymptomatic, they are already carrying the virus without them knowing it and they go to their normal affair, and they infect people, we really never know the right figure unless they do a lot of test in people with symptoms, some countries are not getting tested because of the lack of testing kit.
