I left my office almost empty-handed on the second Tuesday of March. Like many others, I had no idea that six months later I would still be working at home.
Among the few files I grabbed on the way out was a report on the economic impact of the COVID-19 pandemic on the U.S. produced by the London firm Capital Economics.
"Our current working assumption is still that the number of coronavirus cases in the U.S. is restricted to the low tens of thousands," the firm wrote in a report dated March 5.
The worst-case scenario, Capital Economics wrote then, would be the economy contracting for a one-year pandemic, cutting gross domestic product by about 3%. The firm's most likely case was an economic contraction of less than 1% for the year.
The total U.S. confirmed COVID-19 cases last week, though, was approaching 6.5 million, not the tens of thousands, and the firm's worst-case scenario for the economy didn't turn out to be pessimistic enough.
The point of bringing this up is not to pick on an excellent firm, but to show that in early March I wasn't the only person paid to know what's going on who didn't grasp the situation.
And six months into the pandemic in the U.S., the picture does not look that much clearer.
It's still hard to know which of the vaccine candidates will be shown to be safe and effective, or how effective they might be. It's hard to know how quickly vaccines can be distributed.
