Real-time data on everything from sit-down restaurant meals to job hirings shows American business and consumers leaping to take advantage of a fast vaccine rollout even as their European counterparts languish in extended lockdowns.
And while some US health experts express concern at the loosening or outright dropping of Covid-19 restrictions by many states, the outcome, for now, is that it is widening the US head start in the post-pandemic recovery.
Even after an uptick this month for the first time since January, new US infections at 131 per 100,000 over seven days are lower than those in Germany, France and Italy, the top three euro economies, the Reuters Covid-19 Global Tracker shows.
Coupled with a faster vaccine rollout than any in Europe aside from Britain's, that has prompted a tangible return of activity across a US economy already forecast by the International Monetary Fund to return to pre-pandemic health months before the euro area can.
Take restaurants and retail. Diner visits recorded on the OpenTable State of the Industry site show, unsurprisingly, that numbers have continued to flat-line in Germany since late 2020 when lockdown measures were introduced.
In the United States, meanwhile, the chart has regained its habitual pattern of weekend spikes as the overall curve inches closer to its pre-pandemic level.

Google Mobility read-outs on movement trends confirm the same picture for retail as a whole. US mobility levels leapt in January and broke further away from European comparisons in mid-February as Italy and then Germany and France saw declines.

While many European countries still have stringent travel restrictions in place - and some are considering additional ones - the number of US air passengers screened topped 1.5 million this month for the first time in a year.
With some states open for leisure travel despite federal guidance to the contrary, US airline executives see concrete signs of a domestic leisure travel recovery and are optimistic about the summer season.
The buoyant mood is reflected in job postings recorded on the Indeed website, with the US tally having now since January pushed strongly past its February 2020 level while those in France and Germany remain below it.
Finally, a similar disconnect is seen in the composite weekly tracker compiled by the OECD think tank from Google search behaviour in areas such as consumption, labour markets, housing, trade, industrial activity and economic uncertainty.

Such snapshots of economic behaviour must be interpreted carefully. OECD economist Nicolas Woloszko noted for example that drops in mobility over the past two to three months were having smaller effects on activity as firms and households adapted to the new conditions.
Yet the overall picture, combined with faster US vaccine rollout and new Biden administration stimulus of $1.9 trillion, is already enough for many forecasters to start pencilling in a widening of the growth gap between the United States and the euro zone in the first three months of this year.

Already, the Federal Reserve's projection of a 6.5% growth rate for the United States in 2021 compares with a mere 3.7% forecast for the European economy.
Worse, economists such as Gilles Moec at AXA Group see the euro area battling with further restrictions in the second quarter too until vaccine campaigns start to accelerate and cap new infections as promised by European Union officials.
"What is in balance is the fate of the third quarter, since at the current pace of vaccination reaching collective immunity by the summer definitely is a challenge," Moec noted.
