Even as the confirmed U.S. death toll from the coronavirus soared past 50,000, Georgia, Oklahoma and Alaska began loosening lockdown orders Friday on their pandemic-wounded businesses, despite warnings from health experts that the gradual steps toward normalcy might be happening too soon.

Republican governors in Georgia and Oklahoma allowed salons, spas and barbershops to reopen, while Alaska opened the way for restaurants to resume dine-in service and retail shops and other businesses to open their doors, all with limitations. Some Alaska municipalities chose to maintain stricter rules.

Though limited in scope, and subject to social-distancing restrictions, the reopenings marked a symbolic milestone in the debate raging in the United States — and the world — as to how quickly political leaders should lift economically damaging lockdown orders.

Similar scenarios have been playing out worldwide and will soon proliferate in the U.S. as other governors wrestle with conflicting priorities. Their economies have been battered by weeks of quarantine-fueled job losses and soaring unemployment claims, yet health officials warn that lifting stay-at-home orders now could spark a resurgence of COVID-19.

During a White House press briefing Friday, President Donald Trump spoke optimistically of the economy but also asked people to continue social distancing and using face coverings.

"We're opening our country. It's very exciting to see," Trump said.

The coronavirus has killed more than 190,000 people worldwide, including — as of Friday — more than 50,000 in the United States, according to a tally compiled by John Hopkins University from government figures. The actual death toll is believed to be far higher.

In Oklahoma, Gov. Kevin Stitt authorized personal-care businesses to open, citing a decline in the number of people being hospitalized for COVID-19. Those businesses were directed to maintain social distancing, require masks and frequently sanitize equipment.

Still, some of the state's largest cities, including Norman, Oklahoma City and Tulsa, were opting to keep their bans in place until at least the end of April.

Amy Pembrook and her husband, Mike, reopened their hair salon in the northwest Oklahoma town of Fairview after it had been shuttered for about a month.

"We're super excited about going back, but we have caught a little flak from people who say it's too early," Amy Pembrook said. "We just said we can live in fear for a long time or we can trust that everything is going to be OK."

Georgia deaths, infections still rising

With deaths and infections still rising in Georgia, many business owners planned to stay closed despite Gov. Brian Kemp's assurance that hospital visits and new cases have levelled off enough for barbers, tattoo artists, massage therapists and personal trainers to return to work with restrictions.

Kemp's timeline to restart the economy proved too ambitious even for Trump, who said he disagrees with the fellow Republican's plan.

On Friday, Trump signed a $484 billion US bill to aid employers and hospitals under stress from the pandemic — the latest federal effort to help keep afloat businesses that have had to close or scale down. Over the past five weeks, roughly 26 million people have filed for jobless aid, or about 1 in 6 U.S. workers.

Without a tried-and-tested action plan for how to pull countries out of coronavirus lockdown, the world is seeing a patchwork of approaches. Schools reopen in one country, stay closed in others; face masks are mandatory in some places, a recommendation elsewhere.

In Georgia, David Huynh had 60 clients booked for appointments at his nail salon in Savannah, but a clothing store, jewelry shop and chocolatier that share a street corner with his downtown business, Envy Nail Bar, remained closed.

"The phone's been ... ringing off the hook," Huynh said. "We've probably gotten hundreds of calls in the last hour."

Four women clutching face masks were waiting outside when the salon opened for the first time since March 26.

"Yes, I am ready to get my nails fixed," said Alina Davis, a police officer for the local school system, who kept working throughout the crisis.

Meanwhile, Nikki Thomas is overdue for a visit to her hair stylist, but she's barely ventured outside her house in the six weeks since she's been working from home. She had no plans to change that now just because of Kemp's decision.

"It's obviously extremely stupid and I'm simultaneously exhausted and so angry I can barely see straight," Thomas, 40, said in a phone interview.

Some businesses defy Texas order

A handful of Texas businesses reopened Friday in defiance of state guidance in the fight against the coronavirus, which allows retailers to offer "to go" service but leaves other restrictions in place.

In Dallas, hair salon owner Shelley Luther was issued a citation at midday but she refused to close her business. She had two stylists and a nail technician on duty, a fraction of her normal staff. Several supporters came to the salon, including a man carrying a long gun he made into a pole for a Texas flag with a coiled snake on it reading "Don't Tread on Me."

A Houston-area restaurant opened to customers who wanted to eat inside, demarcating available tables by the colour of their tablecloths in an effort to ensure social distancing. A table with a white cloth was open for seating. A table with a black cloth was closed.

"The right to open up in a safe manner, that should be our right," said Matt Brice, owner of Federal American Grill in the upscale enclave of Hedwig Village. "We shouldn't be told we have to shut our business down."

Texas Gov. Greg Abbott earlier this month announced a series of orders intended to restart the state economy, but salons and dine-in restaurant service are not yet allowed. More than 1.3 million people have filed for unemployment in Texas since mid March, and joblessness has skyrocketed nationwide due to coronavirus-related business shutdowns. The state has reported almost 600 deaths and more than 22,000 overall cases of COVID-19.

Abbott has reopened state parks and allowed medical providers to resume performing elective surgeries, including abortions. On Friday, businesses were allowed to start selling goods to go.

Lack of tests and supplies

The gradual reopenings come as coronavirus testing continues to lag across the United States. To date, according to data compiled by the COVID Tracking Project, just under 4.7 million people have been tested in the country of 330 million people.

A lack of tests and supplies has hampered the U.S. effort from the beginning. About 193,000 people were tested on Thursday. That's an increase from the two-week daily average of 163,000, but far less than what public health experts estimate is needed to get a handle on the virus.

Researchers at Harvard have estimated a minimum of 500,000 daily tests are needed, and possibly much more, in order to safely reopen the economy.

In Michigan, Democratic Gov. Gretchen Whitmer lengthened her stay-at-home order through May 15, while lifting restrictions so some businesses can reopen and the public can participate in outdoor activities such as golf and motorized boating.

Michigan has nearly 3,000 deaths related to COVID-19, behind only New York and New Jersey among U.S. states.

New York reported its lowest number of daily COVID-19 deaths in weeks on Friday. The state recorded 422 deaths as of the day before — the fewest since March 31, when it recorded 391 deaths. More than 16,000 people have died in the state from the outbreak.

In Denver, Mayor Michael Hancock extended the city's stay-at-home order and nonessential business closures through May 8 just as Colorado Gov. Jared Polis, a fellow Democrat, prepared to relax some statewide restrictions next week.

Health officials in Colorado ordered the immediate closure of a Walmart in Aurora, a Denver suburb, after three people connected to the store died after being infected with the coronavirus and at least six employees tested positive.
