11:25 a.m.: 100% of New York workforce must stay home

New York Gov. Andrew Cuomo has ordered that 100% of the state's workforce stay home except for essential services.

"Only essential businesses can have workers commuting to the job or on the job," Cuomo said, stressing that this rule "will be enforced."

Everyone else must “remain indoors to the greatest extent” possible, he said.

"This is the most drastic action we can take,” Cuomo said.

Thirty-five people have died in New York from COVID-19, the governor said.

There are 7,102 people diagnosed with coronavirus in New York state, nearly 6,000 more cases than in Washington and California. Cuomo said that’s because New York is doing more tests per capita, including 10,000 tests Thursday night.

He addressed the need for 30,000 ventilators in the state, saying "Ventilators to this war are what the missiles were to World War II."

The governor urged citizens not to take public transit except if urgent and absolutely necessary.

Cuomo also issued a moratorium on residential and commercial evictions for 90 days.

Cuomo said he spoke to some residents who have been in quarantine.

"Most of all, they would all talk about the sense of isolation ... not having human contact and how difficult that was," he noted.

The governor got personal about conversations with his own daughter, who is among those in isolation.

"I had some of the best conversations with her that I have ever had," Cuomo said. "She was alone for two weeks with her own thoughts, not talking to anyone else, no noise, no activity. And we talked about things in depth that we didn't have time to talk about in the past, or we didn't have the courage or the strength to talk about in the past. Feelings that I had about mistakes that I had made along the way that I wanted to express my regret and talk through with her."

7:35 a.m.: 'None of us have the adequate infrastructure for this,' Los Angeles mayor warns

A day after ordering all residents to stay inside their homes unless absolutely necessary in a bid to control the spread of the novel coronavirus, Los Angeles Mayor Eric Garcetti told ABC News that he took the measure with both "a very heavy heart" and "a very clear mind."

"None of us have the adequate infrastructure for this, and our best shot is to push this out" Garcetti said in an interview Friday on "Good Morning America."

"These are acts of love for the people and the precious lives that we want to protect," he added. "The longer that you wait, the worse it's going to be by the time you react."

Garcetti noted there were lessons learned from the Spanish flu, a deadly influenza pandemic that infected about a quarter of the world's population from the start of 1918 through the end of 1920.

"These things we saw in 1918," he said. "The cities that acted quickly were able to protect more people, and those that didn't were devastated."

Meanwhile, California Gov. Gavin Newsom on Thursday night extended the stay-at-home order statewide to nearly 40 million residents. The governor warned that the state projects 56% of California’s population could contract the virus over the next eight weeks.

7:15 a.m.: Andrew Yang's nonprofit to distribute over $1 million to families impacted by virus

Andrew Yang's new nonprofit announced Friday that it will spend more than $1 million helping working families impacted by the novel coronavirus outbreak in the New York area and across the country.

Humanity Forward, which Yang founded after ending his 2020 Democratic bid for president, will start by sending $1,000 to 500 working poor households in New York City's Bronx neighborhood within the next two weeks.

"The coronavirus outbreak has absolutely devastated local economic activity, and working families are feeling it most," Yang said in a statement announcing the initiative. "Many feel like they don’t have money for groceries or rent, even as their child’s school shuts down. Our goal is to get money into their hands as quickly as possible so they can focus on keeping themselves and their families healthy. This is exactly what our government should do, and we are doing it now so that families can get relief as quickly as possible."

6:21 a.m.: Cases rise in Africa

South Africa's health minister announced Friday that the country had recorded 52 new confirmed cases of the novel coronavirus, bringing the national total to 202.

Africa's most industrialized economy has the highest number of confirmed cases of the virus in sub-Saharan Africa. Egypt has the highest total on the larger African continent, with 256 diagnosed cases.

The region has seen a significant increase in COVID-19 infections recently, although there are still fewer diagnosed cases there than in other parts of the world.

More than 800 cases have been diagnosed in at least 34 nations on the African continent as of Friday morning, compared with 147 cases just a week ago. At least 12 of those countries are now experiencing local transmission of the virus.

"The rapid evolution of COVID-19 in Africa is deeply worrisome and a clear signal for action," Dr. Matshidiso Moeti, the World Health Organization's regional director for Africa, said in a statement Thursday. "But we can still change the course of this pandemic. Governments must draw on all of their resources and capabilities and strengthen their response."

5:30 a.m.: Hong Kong reports spike in new cases

Hong Kong recorded 48 new confirmed cases of the novel coronavirus on Friday, according to the government's website.

The news comes after the Chinese mainland reported no new domestic transmissions of the virus for two straight days -- a major milestone in the country's fight against the epidemic.

4:18 a.m.: Quarantined cruise ship passengers reportedly refuse tests

A majority of passengers from the Grand Princess cruise ship who are quarantined at a U.S. Air Force base in California are refusing to be tested for the novel coronavirus, according to a report from San Francisco ABC station KGO.

The cruise ship was granted permission to dock in California's port of Oakland on March 9, after 21 people on board tested positive for COVID-19. All those infected were first transported to local hospitals, then all remaining passengers gradually disembarked over several days. Foreigners were repatriated on charter flights, while U.S. citizens were taken to designated sites for a 14-day quarantine. Crew members who weren't sick stayed on board to complete their 14-day quarantine.

That quarantine period ends next week and passengers are eager to go home, which is apparently why many of them are refusing to be tested.

Only 300 passengers quarantined at Travis Air Force Base in Fairfield, California, have agreed to be tested, while the remaining 545 have declined, according to KGO. They were reportedly told that they are not required to be tested.

"We didn't know for sure when we would get the results," Carmen Kilcullen, 86, of Northern California, told KGO by telephone Thursday. "In case results came in later, we'd have to stay."

3 a.m.: China exonerates whistleblower doctor who warned of virus

In a highly unusual move, Chinese authorities have exonerated a doctor who was officially reprimanded for warning his colleagues about the novel coronavirus and later died from the disease.

The city of Wuhan's public security bureau said in a statement late Thursday that it would revoke the reprimand issued to Dr. Li Wenliang, which accused him of spreading rumors, according to Chinese state television. Wuhan's police department also made an official apology to Li's family, citing "inappropriate handling on the matter," state TV reported.

Li, a 34-year-old ophthalmologist at Wuhan Central Hospital, was detained by police in early January after trying to warn fellow doctors and medical students about the virus in a social media group. Li became infected and died from COVID-19 on Feb. 7.

Li's death sparked outrage in China where citizens took to social media to vent their frustrations over the government's handling of the epidemic and portraying the doctor as a martyr of the crisis.

An investigation team from the state supervision authority determined that police had "issued improper instructions" and followed "improper law enforcement procedure," according to a report released Thursday evening by the Central Commission for Discipline Inspection, the ruling Communist Party's top disciplinary body.

Li's family has also received compensation in the wake of his death, according to the Central Commission for Discipline Inspection's report.
