Nobody is immune to this from before. Everyone might contract this at the same time. We don't know exactly what this is, or what it may become. The infection rates are much higher than flu. Most countries aren't as prepared as some Asian countries that've had to deal with such situations before. After short time with exponential spread, countries will shut down anyway, and then it's too late to avoid becoming Italy. It's prudent to stop or slow this down, until we've had time to prepare and learn more about the disease. Nobody knows anything for sure in this situation. We should've already prepared for this eventuality anyway.
