June 20 coronavirus news

The state of Florida has reported the most cases of coronavirus in a single day since the pandemic began. 

The Florida Department of Health is reporting an additional 4,049 cases of coronavirus on Saturday, bringing the state total to at least 93,797, according to data released by the state. 

As of Friday, the state of Florida had reported a total of approximately 89,748 cases.  

Saturday's numbers mark the highest number of reported cases in a single day the state has seen, according to to the Florida Department of Health. 

The National Institutes of Health announced Saturday that it has halted its trial of the drug hydroxychloroquine for the treatment of adults hospitalized with Covid-19.

The trial enrolled more than 470 adults patients hospitalized with coronavirus, or in an emergency department with anticipated hospitalization. The study found that those patients who were randomly assigned to receive the hydroxychloroquine treatment didn't benefit from the drug, compared to those in the placebo group.

Hydroxychloroquine is typically used to treat malaria and rheumatoid conditions, such as arthritis.

"In various studies, the drug had demonstrated antiviral activity, an ability to modify the activity of the immune system, and it has an established safety profile at appropriate doses, leading to the hypothesis that it may have also been useful in the treatment of Covid-19," the NIH said in its statement.

On Monday: The US Food and Drug Administration revoked its emergency use authorization for hydroxychloroquine to treat hospitalized patients with coronavirus, saying it was unlikely to provide any benefit based on the latest scientific research.

Pope Francis has warned people against falling back into the “illusion of individualism” after the coronavirus pandemic passes.

In statement from the Vatican, Francis praised healthcare workers in Italy’s Lombardy region who stood by their patients during the “troubled months."

Francis warned people to “be careful” to not fall back into making “individualism the guiding principle of society."

The Pope used healthcare workers as an example, saying their professionalism has been “one of the pillars of the country."

Lombardy was Italy’s worst affected region by the virus. 

Tim Murtaugh, the director of communications for the Trump campaign, said everyone attending the President's rally tonight in Tulsa, Oklahoma, will have to have their temperature checked before entering the building due to the coronavirus pandemic.

The campaign will also have masks that people can wear if they want, and will be supplying hand sanitizer.

"People are certainly aware of the situation," Murtaugh told CNN on Saturday, adding that people have the freedom fo choice.

When asked about the waiver attendees had to sign prior to the rally that says the Trump campaign is not liable if they get sick at the event, Murtaugh said it is just "standard language."

"If you buy a ticket to a baseball game, on the back of that, it's a waiver that says watch out you may get hit by a flying ball if it leaves the field of play. That's just standard," he said.

Tulsa's Bank of Oklahoma Center arena holds 19,000 people. More people are also expected to be outside in the overflow area.

More than 1,000 people have now tested positive for coronavirus at a German meat plant, the local district administrator Sven-Georg Adenauer said on Saturday.

So far, the outbreak does not seem to have spread from plant workers to the general population, Adenuer said.

A CNN team arriving to the UK on Saturday experienced the lax and chaotic enforcement of a mandatory quarantine rule put into effect by the British government earlier this month.

Anyone arriving in the UK is required to quarantine for 14 days, a rule that came into effect on June 8.

Passengers are required to provide their contact details, so authorities can ensure quarantine measures are enforced.

On the day the program began, a spokesperson for Public Health England told CNN that a private company would be conducting spot checks with phone calls, rather than in-person visits. There is a long list of exemptions from quarantine, including truckers and those who cross the Irish border.

A CNN team traveling from Reykjavik, Iceland, at Luton Airport, north of London, was asked to fill in an electronic form on their phones before take-off, and submit a long list of personal and contact information.

Passengers filling out the form were given the option of being contacted only by text message, rather than a phone call, if they could provide a reason for the preference. The form was accessed by scanning a QR code, or by manually typing in a URL that featured a series of more than 50 random digits.

On arrival, Luton Airport featured prominent signage advertising the requirements, but there was no verification by authorities of any information submitted in the form. Two agents from Border Force asked that passengers from two planes flash the electronic forms on the phones in order to proceed.

A group of elderly passengers who had not filled out the form in advance was directed to a series of iPads, where they were left to fill out the forms with no assistance.

The UK government has said that quarantine measures were introduced in June precisely because other countries were opening up. Politicians said that reopenings presented a higher risk of new cases of coronavirus arriving from abroad.

Several airlines, including British Airways, Easyjet and Ryanair, have launched a legal action against the quarantine rules, saying the restrictions “will have a devastating effect on British tourism and the wider economy and destroy thousands of jobs.”

CNN's Robert North, Vasco Cotovio and Joe Minihane contributed reporting.

Protesters in Paris have sprayed red paint over the front of the Health Ministry building to “symbolize those who lost their lives” to Covid-19 and to highlight the poor conditions for healthcare workers.

Many of the demonstrators were part of the Association for the Taxation of Financial Transactions and Citizen Action (Attac), a left wing activist group.

Around 30 demonstrators from Attac and Inter-Urgences, an association of paramedical staff, took part in the protest.

The two associations have criticized the French government’s treatment of health workers, including the country's offer of a medal to medical staff. The French state's offer of a bonus for medical workers, awarded using strict criteria, has also been criticized.

The demonstration was the first by health workers since the easing of lockdown in France.

“In the face of this indecency, healthcare staff have decided to show the real face of the government and its ministers by offering them the medal of contempt,” Attac's statement added.

Swedish teen climate activist Greta Thunberg has said the pandemic shows the world can act with “necessary force” when it wants to, while comparing the reaction to Covid-19 with efforts to fight climate change.

Thunberg said people in positions of power in politics, business and finance had said “they will do whatever it takes,” during the pandemic as “you can’t put a price on a human life."

The activist said that when millions had died because of air pollution, those were lives “[society] can put a price on.”

“Those words and this treatment of a crisis opens up a whole new dimension because you see every year at least 7 million people die from illnesses related to air pollution according to the WHO,” she said.

 “Those are apparently peoples whose lives we can put a price on. Since they died from the wrong causes and in the wrong parts of the world.”

Thunberg inspired worldwide climate protests last year after staging weekly sit-ins outside the Swedish Parliament on Fridays from August 2018.
