Unfortunately, we will still have approximately one month of quarantine. This is the safest way to stop the evolution of the virus, for now.
Even if the number of cases will begin to drop, we still have to consider social distancing for a long period from now on. Without a vaccine, the virus will not disappear on its own, so we have to try and keep things in control.
You can read all the predictions about how the situation will evolve but it is important to have in mind that some of them may not go according to plan.
Try not to think so much about how long it will last and focus on making the best of it for however long it takes.
