Not just testing, but treatment. There are a half dozen existing anti-viral drugs currently in testing which can be rapidly deployed if they turn out to be effective because they're already approved and manufactured for other usage.

There are also several new anti-viral compounds and the potential for clonal antibody treatments whos approval might get fast-tracked if they prove highly effective.

Even absent better treatment strong measures taken swiftly will do more than just delay the inevitable. But reducing our critical care saturation we'll save lives. But there is also a very realistic prospect of improved meaningfully treatment in the coming weeks/months.
