US coronavirus: More states are easing restrictions this week, unnerving experts and some local officials

But 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.

Mayors call for more caution

But 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,”https://www.cnn.com/” Ernst said.

In California, while surrounding counties opened their beaches for the weekend, Los Angeles Mayor Eric Garcetti said the city would not follow suit. He 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 this week — but urged residents to stay home “as much as possible.”

But in the state’s biggest city, nothing will change, 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.

But 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.”

Fauci said 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.”

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

First known American to die from Covid-19 suffered heart rupture

Dowd, 57, died February 6. The California woman had not traveled anywhere with a high transmission of the coronavirus prior to her death.

That means coronavirus must have been circulating at least two to three weeks before her death, said Dr. Sara Cody, director of Santa Clara County’s Department of Public Health.

CNN has reached out to the Santa Clara County medical examiner’s office for an independent copy of the autopsy report.

Antibodies don’t necessarily lead to long-term immunity

But 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.

But it’s not clear how long antibodies might protect against subsequent infection, said Dr. Deborah Birx of the White House Coronavirus Task Force.

The US Food and Drug Administration has now authorized three new 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.
