(Bloomberg Opinion) -- Nobody wants to go back to a national coronavirus lockdown. France’s Emmanuel Macron and Spain’s Pedro Sanchez are ruling out blanket stay-at-home restrictions, even as Covid-19 cases surge higher. Their motives are clear: Another round of widespread lockdowns would tank the economy and split society, and would also be an admission of defeat from politicians and public-health officials who — like Sanchez — insist we are “better prepared” to control the epidemic than we were in the dark days of spring.

The less draconian strategy of combining preventative measures, while waiting for a vaccine to emerge, is a commendable one. But there are limits here, too. Mask policies are becoming tougher and more complicated, risking confusion and hostility. International travel curbs, which haven’t always proven effective or easy to enforce, are piling up again. And while testing and tracing are vital for improving our ability to catch cases, resource gaps remain. Spain is enlisting the army to help its efforts.
