September 28 coronavirus news

The biotechnology company Inovio's planned Phase 2/3 coronavirus vaccine trial has been put on a partial hold, the company announced on Monday.

The announcement notes that the US Food and Drug Administration notified the company that it has additional questions about the company's planned Phase 2/3 trial of the vaccine candidate INO-4800, including questions about the device to be used as part of delivering the vaccine in the trials.

Until the FDA's questions have been "satisfactorily addressed," the Phase 2/3 trial is on partial clinical hold, according to the company announcement.

"This partial clinical hold is not due to the occurrence of any adverse events related to INOVIO's ongoing expanded Phase 1 study of INO-4800, the conduct of which may continue and is not impacted by the FDA's notification," the announcement says. "In addition, this partial clinical hold does not impact the advancement of INOVIO's other product candidates in development."

Some context: Inovio’s Covid-19 vaccine is being funded, in part, by the US Department of Defense, the Bill & Melinda Gates Foundation, and The Coalition for Epidemic Preparedness Innovations.

The company has not received funding from Operation Warp Speed, the Trump administration’s initiative to fast-track the development and delivery of a Covid-19 vaccine.

NBC News reported Monday that US Centers for Disease Control and Prevention Director Dr. Robert Redfield was overheard during a phone call in public on a commercial airline saying, "Everything he says is false.”

NBC News, which heard the comment, said Redfield acknowledged after the flight from Atlanta to Washington, DC, that he was speaking about Dr. Scott Atlas, a neuroradiologist who joined the White House Coronavirus Task Force in August. 

NBC said that Redfield, in the conversation with a colleague on Friday, suggested Atlas is providing President Trump with misleading data about the efficacy of masks, young people’s susceptibility to the coronavirus and herd immunity.

In a statement to CNN, a CDC spokesman did not deny the conversation took place:

A federal health official tells CNN, more broadly, “bottomline, the story is accurate.”

CNN has reached out to the White House for comment.

CNN has reported that Atlas – a critic of severe lockdowns who was supported herd immunity strategies against the coronavirus – has found himself at odds with other medical experts in his administration, including Dr. Anthony Fauci and Dr. Deborah Birx.

On Friday, Fauci said during an interview that the Trump administration has pivoted away from receiving daily guidance from the White House Coronavirus Task Force to focus more heavily on the economy. “We're meeting now on an average of one and at the most two times a week,” Fauci said.

As cases spike in parts of New York City, Gov. Andrew Cuomo warned that Covid-19 "remains a force to be reckoned with throughout the country."

Experts have cautioned the US could see an explosion of coronavirus cases in the fall and winter as people exercise less caution and spend more time indoors.

Already the US has reported more than 7.1 million cases and 204,756 deaths since the pandemic began, and 21 states are reporting more new cases in the last seven days compared with the week before, according to a CNN analysis of data from Johns Hopkins University.

Once the epicenter of the pandemic in the US, New York had boasted a test positivity rate — the percentage of tests being performed that come back positive for the virus — of less than 1% for more than a month. That rate broke 1% on Saturday as Cuomo reminded New Yorkers "we cannot drop our guard."

Though the rate of positive tests is still low relative to other states, neighborhoods in Queens and Brooklyn are seeing cases "continue to grow at an alarming rate," according to a news release from the city's Department of Health.

But New York is still among the states with the lowest positivity rate in the US. The World Health Organization advised that the rates of positivity in testing should remain at 5% or lower for at least 14 days before businesses reopen. Currently, 22 states and the District of Columbia meet that recommendation, with Vermont holding the lowest rate at 0.53% positive.

Twenty-eight states and Puerto Rico have positivity rates higher than 5%. The territory has a 100% positivity rate. Among US states, the rate is highest, 24.64%, in South Dakota, according to Johns Hopkins University.

Nearly 1 million people across the world have died since the start of the coronavirus pandemic and new outbreaks are continuing to crop up.

The World Health Organization has warned that a doubling of that number is "certainly unimaginable, but it's not impossible," if countries don't work together to suppress the virus' spread.

In the United States, India and Brazil -- which account for more than half of all global cases -- the pandemic shows no sign of slowing down.

The US, which surpassed 7 million cases on Friday, could see an explosion in Covid-19 infections as fall and winter set in, health experts warn. India, which hit 6 million cases on Monday, isn't far behind -- the country has recorded 5 million infections in the past two months alone. And the pandemic continues to roil South America. Though Brazil is the region's worst-affected nation, with more than 4.7 million infections, Argentina, Colombia and Peru are recording thousands of new cases daily.

Several countries in Europe are also seeing an increasing trend in case numbers, after lockdown policies were lifted over the summer, contributing to a new surge. Second waves are underway in the United Kingdom, Spain and France.

What you need to know about coronavirus on Monday, September 28

Numerous scientists have studied how the 1918 flu spread to become the deadliest pandemic in history and which interventions worked, research that is becoming increasingly relevant during the current coronavirus crisis.

But little research has been done on how environmental conditions affected the 1918 pandemic -- until now.

The 1918 flu coincided with the final years of the World War I, and it's been well documented that heavy rain and cold temperatures impacted many battles. Now, a new study reveals that the cold, rainy weather was part of a once-in-a-century climate anomaly that occurred from 1914 to 1919 and added to the severity of the 1918 pandemic.

A team of more than a dozen scientists collected and analyzed an Alpine ice core to reconstruct the environmental conditions of Europe during the World War I. The process involves using a laser that melts a tiny bit from the ice surface and analyzing the chemicals released from each layer of water vapor. It's so precise they can pinpoint exact seasons from each layer of ice.

Researchers then compared that ice core data to historical records of deaths during that time period and records of precipitation and temperatures from each month.

The researchers discovered that lingering cold, wet weather during the winters of 1915, 1916 and 1918 was caused by abnormally high rushes of marine air from the North Atlantic. Deaths in Europe peaked three times during World War I and all the spikes occurred during or soon after heavy rain and cold weather, according to the study.

How climate change affects pandemics

Failed quarantine measures in two hotels in the Australian state of Victoria lead to the deaths of 768 people and the infection of 18,418, according to closing submissions at the Covid-19 Hotel Quarantine Inquiry.

Ben Ihle, counsel, assisting at the Victorian inquiry, said that the hotel quarantine became a "seeding ground" for the virus, as authorities linked the massive Covid-19 outbreak in Victoria to the hotel cluster using genomic sequencing.

"On the 23rd May, Victoria's Covid-19 death toll was 19. As of today, the total number of Covid related deaths in Victoria is 787," Ilhe added.

The number of cases in the state has risen exponentially from June to the present day. "As of 15th June, Victoria had record 1,732 confirmed cases of Covid-19. As of today, that number 20,150," Ilhe said.

The movement of the virus from the hotel cluster to the rest of the state was responsible for 99% of infections in the state, added Ilhe.

An expert on the spread of Covid-19 proclaimed last week that the pandemic in Sweden was essentially over — the virus there was "running out of steam," he said, as researchers suggest Swedes could be building immunity.

Such comments have emboldened governments flirting with the idea of adopting Sweden's "light-touch" approach, in the hope they can soften the blow to their economies.

There was reason for optimism when Kim Sneppen, from the Niels Bohr Institute in Copenhagen, made his comments. Sweden's infection and death rates had been low for weeks, despite a second wave rolling over Europe. It seemed to mark a turnaround for the country, which experienced one of the highest death tolls in the world per capita during the spring.

Some countries are eying Sweden's 'light-touch' Covid response. It's a gamble that could backfire

Coronavirus admissions at intensive care units (ICU) in the Provence-Alpes Côte d'Azur region of southern France have tripled since the beginning of September, according to official statistics.

Marseille spike: Bars and restaurants closed for seven days in the Marseille area, starting Sunday night, due to the deteriorating situation there.

The situation in the south of France will be reviewed after seven days, and could be extended by a further week if there is no improvement, the French Health Minister tweeted.

"We have learned about the virus and we have organized ourselves so we can mobilize up to 12,000 resuscitation beds," Olivier Veran wrote on Twitter.

Overall, France has recorded 538,569 coronavirus patients since the start of the outbreak, with an additional 11,123 logged in the 24 hours leading up to Sunday 8 a.m. ET. 

At least 31,727 people have died, with 27 registered in the 24 hours leading up to Sunday, said the health authority.

One-third of American parents have no plans to get their children vaccinated for the flu this year, according to the National Poll on Children's Health released Monday, despite the very real possibility their child could also catch the deadly Covid-19.

In addition, two-thirds of parents don't believe getting a flu shot for their child is more important this year, despite advice to the contrary from major government organizations and pediatricians.

"Children younger than 5 years old -- especially those younger than 2 -- are at high risk of developing serious flu-related complications," the US Centers for Disease Control and Prevention said, adding that getting a flu shot during the pandemic -- for all ages -- is more important than ever.

Dr. Anthony Fauci, the nation's leading infectious disease expert, once again stressed the importance of getting a flu shot this year, while speaking during the CITIZEN by CNN Conference on Tuesday.

"You should get it no later than the end of October," he told the moderator, CNN Chief Medical Correspondent Dr. Sanjay Gupta. "If it's available now, you should get it now."

"Don't wait until any time beyond October," he added.
