Stopping stupidity would be more prudent.
There is a big list to make why this quarantined situation will only work out for the worse, the virus itself if actually the least of our problems, at the present time. However, in order for it to happen, people will have to accept that the virus cannot be stopped unless we allow our own bodies to stop it. And we need to properly measure where the virus is, which is also only done when people are close to dying, while those people are only in danger themselves, while the ones spreading the dangers are not tested. Quarantining them won't work, all that will happen is that the virus will come back with a vengeance once the quarantine is lifted which must happen someday.
And time travel is the worst "solution" to everything. Doing that is even more dangerous than the end of the world.
