i don't know from indexes, but this sounds discouraging

The Wuhan Coronavirus in Great Britain

Naturally, the lockdown has produced devastating economic effects. According to this report, an index measuring activity in the manufacturing and service sectors dropped from 53.0 in February to 38.0 in March. A reading below 50 indicates a contraction. And the lockdown didn’t go into effect until late March.

By late April, a month into the formal lockdown, the same number had fallen from 38.0 to 12.9 and the British economy was said to be “crumbling.” Jam Vlieghe, the interest rate setter at the Bank of England, declared “we are experiencing an economic contraction that is faster and deeper than anything we have seen in the past century, or possibly several centuries.” The recovery is unlikely to be swift, he added.
