Only six months after Italy’s coronavirus crisis became a warning to the West about how quickly the virus could strain even the best-resourced health systems in the world, the World Health Organization warned today of a “very serious situation” unfolding again in Europe. Italian officials are once again reporting around 1,500 new infections each day. That’s not yet anywhere near the last peak of 6,500 — but it’s a significant rise from 200 in early July. France and Spain, currently the hardest-hit countries in the region, are tracking an onslaught of cases even worse than their springtime peaks.
