The coronavirus pandemic has upended life across the globe. Health care systems scramble to control the virus and governments are instituting strict social distancing measures to try to flatten the curve. The situation is constantly evolving as COVID-19, the disease caused by the coronavirus, rapidly spreads. 

We has been tracking the outbreak since it was first traced to a novel coronavirus in early January. We have compiled answers to basic questions, ways to protect yourself and others, where you can and can't go in lockdown and advice for staying healthy and entertained during long periods at home. 

Here are the latest developments in the coronavirus outbreak each day.

White House warns of heavy possible death toll in US

As many as 100,000 to 240,000 Americans could die from the coronavirus pandemic even with measures like social distancing, a model presented by the White House showed. But the model, from the Institute for Health Metrics and Evaluation, is based on data from Italy, New York and New Jersey, which have suffered serious outbreaks, and doesn't necessarily reflect what will happen elsewhere. "Models are only as good as the assumptions you put into them. As we get more data, you put it in, and that might change," said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

The dire projections would come to pass if there were major outbreaks in big cities like Houston, Dallas, Chicago and Los Angeles, said Dr. Deborah Birx, the White House coronavirus task force coordinator. "I don't believe that's going to happen," she said, basing her view on early favorable developments in cities like Seattle and Los Angeles. Even in Italy, "they're beginning to turn the corner in terms of new cases." 

Even with social distancing showing some positive results, though, President Donald Trump warned it's "going to be a very bad two or three weeks." The US federal government has nearly 10,000 ventilators, a key piece of medical equipment for treating the respiratory problems caused by COVID-19, but it's withholding most of them now. The government has sent 400 to Michigan, 300 to New Jersey, 150 to Louisiana and 50 to Connecticut, Vice President Mike Pence said. Another 450 each are being sent now to New York and Illinois.

US deaths outnumber China's

The US, Italy, Spain and France all have more deaths than China, according to tracking numbers from John Hopkins University and Medicine Coronavirus Resource Center. As of 2:00 p.m. PT on March 31, Italy is sitting at 12,428 deaths; Spain at 8,269 deaths; the US at 3,606 deaths; France at 3,532 deaths; and China at 3,309 deaths.

Apple reportedly planning to pay hourly contractors

Apple has committed to paying its hourly contract workers, according to the Wall Street Journal. This reportedly includes janitors, bus drivers and other campus workers whose jobs have been suspended due to the spread of COVID-19.

CNN anchor Chris Cuomo tests positive 

Chris Cuomo, CNN anchor and brother of New York Gov. Andrew Cuomo announced that he's been diagnosed with COVID-19 and is quarantined and working from his home basement. "I will do my shows from here," he wrote in a statement. "We will all beat this by being smart and tough and united." Andrew Cuomo has been a highly visible figure in the crisis and Chris Cuomo has covered the pandemic extensively on his daily news show, Cuomo Prime Time. 

PC sales double as people work from home

PC sales have doubled compared to this time last year, according to data from analyst firm NPD Group. Computer monitor sales are up twofold, mice and keyboard sales have grown by 10% and notebook sales are also up 10%. "Even as we are all stuck in our homes, sheltering in place or under quarantine, work demands continue," Stephen Baker, VP and industry advisor of NPD's Technology and Mobile, said. "The shift to working from home has also breathed new life into categories that were in decline, such as web cameras."

March 30

States extend lockdown orders

With the federal social distancing guidelines extended through the end of April, several states and counties have announced longer lockdowns for residents.

1. Virginia extended its lockdown to June 10.
2. Maryland issued lockdown orders that go into effect at 8 p.m. ET Monday.
3. Florida: Four counties in Southeast Florida are on lockdown until mid-May.
4. California: The San Francisco Bay Area has extended its lockdown, originally meant to end April 7, to at least May 1.
5. Pennsylvania: 26 counties are now on lockdown until April 30.
6. Washington DC extended its lockdown for an indefinite period, enforceable by a fine of up to $5,000 and imprisonment of up to 90 days.

EPA: Don't flush wipes

In an effort to prevent clogging plumbing during the coronavirus, the US Environmental Protection Agency is urging people to only flush toilet paper. "Preventable toilet and sewer backups can pose a threat to human health and present an extra challenge to our water utilities," EPA said. "Flushing anything other than toilet paper, including disinfecting wipes, can damage internal plumbing, local sewer systems and septic systems."

US crosses testing milestone

The US has tested 1 million samples for the coronavirus and has ramped up its testing capacity to 100,000 samples a day, US President Donald Trump said at the White House's daily briefing. The administration also said that the US has developed 20 different emergency testing options and that tomorrow Abbott Laboratories will begin shipping a rapid test that can return a positive result in as quickly as five minutes. 

March 29

Federal guidelines extended to April 30

President Trump has extended federal guidelines advising social distancing to the end of next month. The guidelines ask Americans who are older or have underlying health conditions to stay home, as well as anyone who is sick. The guidelines were released on March 16 and were originally expected to last 15 days.

Last week, Trump had said he would like to see people attending services on Easter, which falls on April 12. At a press conference announcing the extension of the guidelines, Trump said his comments about packing churches for the holiday were "an aspiration." Based on current models, he added, ending the guidelines now could lead to a situation where death numbers go down and then spike up again. "We don't want that to happen," Trump said.

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, endorsed the extended guidelines based on new models showing that 100,000 to 200,000 Americans could die of coronavirus. 

March 28

No New York area 'quarantine'

Early in the day, Trump said he might impose a short, "enforceable" travel quarantine on the New York metropolitan region, including parts of New Jersey and Connecticut, to restrict travel out of the area. But New York Gov. Andrew Cuomo said he hadn't had any conversations with Trump about such a move.

Later Saturday, the US Centers for Disease Control and Prevention instead issued a domestic travel advisory, urging residents of New York, New Jersey and Connecticut not to travel for 14 days. This unusual move led Trump to tweet that a "quarantine will not be necessary."

Separately, Cuomo said the death toll in the state had reached 728, with the total number of cases climbing above 52,000. New York City itself has over 29,000 cases, with more than 500 deaths as of Saturday morning, officials said. Cuomo also tweeted that New York would move its presidential primary to June 23. It was originally set for April 28.

Tragic new milestones

Two days ago, the US reached 1,000 deaths due to coronavirus. On Saturday, that figure crossed 2,000. And a baby in Chicago became the first infant in the US to die from coronavirus, according to CNN.

In Italy, the number of deaths passed 10,000.

Ireland says stay at home

In Europe, Ireland joined the list of countries issuing lockdown orders. "You can buy food and attend medical appointments and even get out for some exercise but you are being asked to do as little as you possibly can," reads a notice on a government website.

5-minute virus test gets OK from FDA

Under an emergency-use authorization, the US Food and Drug Administration approved a coronavirus test that can offer results within minutes. "You can get a positive result in five minutes and a negative result in 13 minutes. You can walk into a clinic and literally get results while you are there," an executive at Abbott Laboratories, which developed the test, told Reuters. Abbott said it plans to begin distributing the test next week and will increase manufacturing to 50,000 tests per day, the news agency reported. A week ago, the FDA approved a coronavirus test with a detection time of about 45 minutes.

Deaths in the US have topped 1,500, while deaths in Italy are at more than 9,000 and in China are almost 3,200. China is re-closing all of its theaters nationwide, according to Deadline.

Trump signs up GM and Boeing

Trump invoked the Defense Production Act to force General Motors to make ventilators, he said during a coronavirus task force briefing. It came after Trump tweeted earlier Friday that GM must "start making ventilators now." After signing agreements with other private companies, Trump said there'll be 100,000 more ventilators in the next 100 days -- and said any excess units will be given globally to countries that need them most.

Boeing is also pitching in, and will make thousands of plastic face shields each week and supply three planes to carry supplies, Trump said.

US House passes $2 trillion stimulus package

Trump pushes new guidance as US tops global cases

The US now has the most coronavirus cases globally at around 82,400, surpassing China's 81,700. Trump called it "a tribute to our testing." The president said he spoke with the governors of all 50 states and US territories on his idea to classify counties as either low, medium and high risk in an effort to update guidance on social distancing. "Our country has to go back to work," he said during a White House coronavirus task force briefing.

Trump also spoke to G20 world leaders, including Germany, Australia, Russia, China, Japan, India and Saudi Arabia, as well as organizations like the UN, European Commission, WHO, World Bank and the IMO, to discuss how each are dealing with the pandemic.

"I gave it two weeks and we'll assess at that time," said Trump, referencing his 15-day timeline to slow the spread. "But we have to open this country up." 

Speaking further on the Easter plan during the White House briefing Tuesday afternoon, Trump conceded that some sections of the country may have to be opened one at a time.

Trump says US will be open for business 'soon'

During a White House briefing, President Trump said the US "wasn't built to be shut down," and he is hoping local data can be used to advise areas of when they can "cautiously" resume normal activities. "America will be open for business a lot sooner than three or four months," the president said. "We cannot let the cure be worse than the problem itself."

Dr. Deborah Birx, White House coronavirus task force coordinator, said self-collected nasal swabbing is going to be made available later this week at clinics and drive-through sites. Birx added around 250,000 people have been tested in the last week.

Trump is also pushing an anti-malaria drug to be used in coronavirus tests, saying distribution of the drug, hydroxychloroquine, will begin tomorrow in New York City. It follows NY Gov.
