Let's be clear about what is going on here. The quarantine has only one purpose: to try to create a situation where the many people who are going to die (primarily people aged 60+) do so in hospitals under the care of doctors and nurses over a period of 12 months, instead of dying in the next six weeks in their homes or in hospital waiting rooms. That is as true here, as it is anywhere else in the world.
Nobody pretends that the virus will be exterminated in Argentina on April 13, or on any other day. Any date that the official quarantine ends is too soon. Here, in the US, in Europe. Everywhere. Even after it ends, whatever day that may be, we are all still in quarantine. And for those of us aged 60+, that quarantine is even more important. People will naturally try to resume their former lives the day the quarantine lifts. They won't be able to sustain it for long, when they realize the people around them who are doing the same, are becoming gravely ill, and, in too many cases, dying.
No social or economic activity that depends on people coming physically together is going to be possible for many months, anywhere in the world, regardless of the day an official lockdowns, quarantines, or social distancing are lifted. Entire industries (such as hospitality, and airlines) will not restart. These activities will only become possible when there is a vaccine, or when herd immunity starts to have a major impact.
We need to start getting our heads around this. And getting ready for it.
