(Reuters) - Wall Street erased early gains to fall 1% on Friday, as the state of New York ordered all non-essential workers to stay home to curtail the spread of the coronavirus pandemic that has fuelled the worst monthly rout in U.S. equities in three decades.
California had earlier asked 40 million people to stay indoors as the U.S. death toll from the outbreak topped 200 people.
New York state also pleaded for more medical personnel and supplies to treat the virus cases that could overwhelm hospitals.
The Dow Jones and Nasdaq had eked out gains in early trading as global policymakers turned on all the taps to prop up financial markets after four weeks of steep declines ended a record 11-year bull run for Wall Street.

Investors are now counting on further easing in the next few days, as the Senate mulls a $1 trillion package that would include direct financial help for Americans.
"I don't think we're out of the woods by any stretch," said Lamar Villere, portfolio manager at Villere Balanced Fund.
"Most people haven't been tested yet for coronavirus so the size of the spread is not known or understood. As that number goes up there's the potential for more investor caution."
Fears over the severity of the outbreak have wiped off nearly 30%, or more than $8 trillion, from the value of the benchmark S&P index since its record closing high on Feb. 19.
Markets also face "quadruple witching" on Friday, where investors unwind positions in futures and options contracts before their expiration.
