NEW YORK (REUTERS) - Americans must resist the impulse to ease social-separation measures at the first glimpse of progress now being seen in the coronavirus battle, state government and public health leaders warned on Thursday (April 9), as the US death toll surpassed 16,500.
Calls for heightened vigilance, countering talk from the Trump administration of reopening the economy next month, came as new evidence emerged that stay-at-home restrictions were working to flatten the arc of infections in New York state, the US epicentre of the pandemic.
The number of newly hospitalised patients in New York dropped for a second day, to 200. Governor Andrew Cuomo said it was a sign that social distancing was succeeding, even though the number of coronavirus-related deaths in the state rose by 799 on Wednesday, a record high for a third day.
"You can't relax. The flattening of the curve last night happened because of what we did yesterday," Mr Cuomo said, referring to the slope of data when plotted on a graph.
The apparent progress in efforts to slow the spread of the highly contagious virus were also reflected in fresh computer models scaling back the projected nationwide death toll to 60,000, down from earlier forecasts of at least 100,000.
New York state has now recorded more than 7,000 deaths from Covid-19, the respiratory disease caused by the virus.
Perhaps nowhere was the grim calculus of the pandemic more evident than on Hart Island, a potter's field at the western end of Long Island Sound, where contract labourers have been burying two dozen bodies of Covid-19 victims a day in pine caskets lowered into freshly dug trenches.
New York state alone has accounted for nearly half the total loss of life in recent days across the United States, which leads the world in total number of known infections at more than 460,000.
In a stark reminder of the singular peril posed for prisons and other institutions where large numbers of people are confined in close quarters, Chicago's largest jail reported that about 450 of its inmates and staff have tested positive for Covid-19.
The surge of cases at the Cook County Jail marked the latest in a series of coronavirus flare-ups in lockups across the country and one of the largest known clusters of infections in a single US location.
Dr Anthony Fauci, the nation's top infectious disease expert, said it was important that people continue to stay home.
"We've got to continue to redouble our efforts at the mitigation of physical separation in order to keep those numbers down and hopefully even get them lower than what you've heard recently," Dr Fauci, director of the National Institute of Allergy and Infectious Diseases, said on CBS' This Morning.
A University of Washington model often cited by public health experts projects that Covid-19 will claim 60,415 American lives by Aug 4, assuming current social distancing measures stay in place, with the peak coming on Easter Sunday.
Mr Cuomo likened the crisis to the Sept 11, 2001, attacks, which killed almost 3,000 people, most of them at Manhattan's World Trade Center, calling the current emergency a "silent explosion that just ripples through society with the same randomness, the same evil".
Stay-at-home orders closing non-essential workplaces in 42 states have strangled the once-humming US economy and idled millions of workers - a consequence borne out by 16.8 million Americans filing claims for unemployment benefits during the past three weeks, as of Thursday.
"In its first month alone, the coronavirus crisis is poised to exceed any comparison to the Great Recession," said Mr Daniel Zhao, senior economist at recruitment firm Glassdoor, referring to the downturn triggered by the 2008-09 global financial crisis.
Small businesses and workers, particularly in the service industries, have been hardest hit.
Outside Grand Rapids, Michigan, Ms Jocelyn Ockerse, 22, recently lost her job as a hairdresser while her husband, a driving instructor, also is out of work. Neither has been approved for unemployment benefits.
"We are struggling mentally and financially, but if further restrictions slow this thing down and help save lives, then I'm all for it," Ms Ockerse told Reuters through Twitter messages.
The virus has turned the work of those still employed, such as 35-year-old driver Excelso Sabulao, into hazardous occupations, where infection risks loom with every food pick-up and delivery.
"I'm just putting my faith in God that, you know, somehow, while doing this, I'm gonna be spared from getting infected by this," said Mr Sabulao, who uses his own car to deliver for Amazon in Dublin, California. "I can't afford it."
In the latest unprecedented effort to support the economy, the US Federal Reserve on Thursday announced a US$2.3 trillion (S$3.25 trillion) package to keep local governments and small and mid-sized businesses afloat.
Fed chairman Jerome Powell warned against re-opening the economy too soon.
Officials serving on President Donald Trump's economic team were more bullish.
Asked on CNBC whether he believed the economy could be restarted as early as next month, Treasury Secretary Steven Mnuchin said on Thursday, "I do." As soon as Mr Trump "feels comfortable with the medical issues", he said.
White House economic adviser Larry Kudlow told Fox Business the economy should be able to reopen "on a rolling basis" over the next month or two.
Michigan Governor Gretchen Whitmer, like many of her peers in other states, was moving in the other direction, ordering stay-at-home directives extended through at least April 30.
Citing data that suggest social distancing was working, California Governor Gavin Newsom said daily admissions to intensive care units in his state had dropped for the first time in recent weeks, by nearly 2 per cent, on Thursday.
