More states are easing coronavirus restrictions this week, unnerving experts and some local officials – CNN

Iowa will allow elective surgeries to resume and farmers markets to reopen starting Monday.

Tennessee restaurants can welcome customers at 50% capacity, and retail stores can reopen under those same guidelines Wednesday, Tennessee Gov. Bill Lee said.

States forge ahead

Some states have already started reopening. Hawaii has reopened beaches for visitors to fish and exercise, but loitering will not be allowed, Gov. David Ige said Saturday.

And Alaska has allowed many salons and restaurants to open, though they can't exceed 25% capacity.

In Oklahoma, salons, barbershops, spas and pet groomers took appointments Friday, and some state parks and outdoor recreation areas also reopened.'

In New York -- the hardest-hit US city -- the goal is get people back to work, Mayor Bill de Blasio said.

De Blasio announced the formation of a "Fair Recovery Task Force, which will deliver a preliminary road map by June 1 for the state's recovery from the economic effects of the pandemic.

Gov. Andrew Cuomo said New York state has seen a rise in domestic violence, alcoholism, drug use and demands for mental health treatment. But the earliest the state will begin its first phase of reopening is May 15, and then only in regions that have seen a 14-day decline in hospitalizations, he said.

If everything goes well, Cuomo said he expects to see parts of upstate New York open first, and the construction and manufacturing sectors open first with "certain precautions."

New Jersey, the only other state beside New York with more than 100,000 cases, is "still a number of weeks away" from reopening, Gov. Phil Murphy told NBC's "Meet the Press" on Sunday.

In Florida, which has more than 31,000 cases and where a stay-at-home order is set to expire Thursday, Gov. Ron DeSantis is not ready to announce a reopening date.

"We are going to do everything in a smart way," DeSantis said. "I am less concerned about the date and more concerned about getting it right."

Mayors call for more caution

Some mayors say their cities shouldn't reopen yet because a surge in coronavirus cases would set the economy back further.

Atlanta Mayor Keisha Lance Bottoms tweeted a chart Saturday showing the numbers of coronavirus cases and deaths in the area.

"If you're getting your nails done right now, please share these noon numbers with your manicurist #StayHomeGeorgia," the mayor tweeted.

In the nearby suburb of Brookhaven, Mayor John Ernst said he would rather nonessential businesses wait until Georgia reaches a 14-day downward trend in cases.

"Even the (business owners) who open up say, 'I don't know if I'm doing the right thing,'" Ernst said.

But the images of crowded beaches were in stark contrast to scenes in Los Angeles County, where beaches remain closed through May 15 under the county's stay-home order. Los Angeles Mayor Eric Garcetti urged residents to stay inside.

"We can't let one weekend reverse a month of work that you have invested in," he said.

In Colorado, Gov. Jared Polis announced he is letting stay-at-home orders expire Sunday but urged residents to stay home "as much as possible."

Polis said while he is worried about a second spike later this year, his administration is targeting a policy of 60% to 65% "social distancing from the way people used to live," he told CNN.

On Monday, April 27, retail businesses can open for curbside delivery, real estate home showings can resume, and elective surgeries are allowed if facilities are following protocols, according to an order Polis signed Sunday.

On May 1, retail businesses can phase in public openings if they are implementing best practices, and personal services can reopen.

On May 4, offices can reopen at 50% staffing capacity if best practices are being implemented, although businesses are still encouraged to continue to allow employees to telecommute when possible.

Asked if he's worried his state's plan could cost lives, Polis said, "What matters a lot more than the date that the stay-at-home order ends is what we do going forward."

In the state's biggest city, nothing will change Sunday, Denver Mayor Michael Hancock said.

"Stay in place and know that none of the locations that were closed during the order will open up," Hancock said.

Fauci says 'we're not there yet' with testing

A key component to safely reopening the economy is adequate levels of testing, health officials have said.

Dr. Anthony Fauci, a member of the White House Coronavirus Task Force, says the US should double the number of diagnostic testing for coronavirus over the next several weeks.

"We're getting better and better at it as the weeks go by, but we are not in a situation where we say we're exactly where we want to be with regard to testing," said Fauci, the director of the National Institute of Allergy and Infectious Diseases.

"I think we're going to get there, but we're not there yet."

The US needs to "have enough tests to respond to the outbreaks that will inevitably occur as you try and ease your way back into the different phases," Fauci said.

The type of tests are important, too, Dr. Deborah Birx of the White House coronavirus task force told "Meet the Press" on Sunday. She said health experts need to be able to conduct tests for antigens -- substances that stimulate the body's immune response -- "rather than constantly trying to detect the actual live virus or the viral particles itself."

"We have to have a breakthrough," she said. "This RNA testing will carry us certainly through the spring and summer, but we need to have a huge technology breakthrough -- and we're working on that at the same time."

It's not just testing the US needs more of, Fauci said. Contact tracing, identification and isolation of those infected are also key elements to helping slow the outbreak.

Antibodies don't necessarily lead to long-term immunity

As of Friday, no study has "evaluated whether the presence of antibodies to (the virus) confers immunity to subsequent infection by this virus in humans," the WHO brief says.

It's not clear how long antibodies might protect against subsequent infection, Birx said.

The US Food and Drug Administration has authorized three coronavirus antibody tests, bringing the total number of FDA-authorized tests to seven.

The tests were approved under emergency-use authorizations, a lower regulatory standard used when the FDA believes a test's benefits could outweigh any risks.
