September 28 coronavirus news

Wisconsin reported 2,817 new cases on Saturday, the state's highest single-day increase in cases. The previous record was set Sept. 18 with 2,533 cases, according to the Wisconsin Department of Health Services. On Sunday, 2,217 new cases were reported for a total of 115,862 cases statewide, according to the department.

The state has seen a big rise in cases among 18- to 24-year-olds

"But as concerning, is the fact that in my community in Dane county, the university is integral to the city of Madison. It is not separated somewhere. So these young people interact with people throughout the community. They have parents and grandparents and go to the store so we're incredibly concerned about the spike that we're seeing," Parisi added.

Last week, Wisconsin Gov. Tony Evers issued an executive order mandating face coverings in an effort to keep infections down. In a news release, his office attributed rising cases primarily to infections among 18- to 24-year-olds and said the state was "facing a new and dangerous phase" of the pandemic.

"We need your help to stop the spread of this virus, and we all have to do this together," Evers said.

Watch:

The US stock market rallied on Monday, ignoring negative headlines that weighed on the market over the past few weeks in favor of hoping for a stimulus deal out of Washington.

Here's how things look:

What this is about: Investors are hoping that Congress will agree on a new stimulus deal, despite fruitless negotiations in recent months.

On Sunday, House Speaker Nancy Pelosi told CNN that House Democrats may offer their latest stimulus proposal as legislation if revived talks with the Trump administration do not yield a deal her party can get behind.

Even as investors are feeling good about a possible deal, economists are a bit more pessimistic. Morgan Stanley became the latest bank to downgrade its growth outlook because of the slimming chance of another stimulus bill this year.

But this doesn't mean the worries that pushed stocks lower in the past weeks are gone. In fact, not that much has changed from last week, and volatility remains high. The CBOE Volatility Index, or VIX, is more or less flat Monday but remains in elevated territory even though it has come down from the panic-fueled levels it has hit earlier this year.

The impending presidential election, uncertainty about the future path of Covid-19, worries about rising infections in the winter and a slowdown of the economic recovery have been weighing on the market for weeks.

Almost half of US states are reporting increased numbers of new Covid-19 cases as health experts warn of a potential coronavirus surge in the fall and winter.

According to the latest Johns Hopkins University data:

The US meanwhile could see an explosion of Covid-19 cases in the fall and winter as people exercise less caution and spend more time indoors, where there is a greater likelihood of transmission, according to Dr. Chris Murray, director of the University of Washington's Institute for Health Metrics and Evaluation (IHME).

Murray says the IHME model shows a "huge surge" expected to take off in October "and accelerate in November and December." 

The IHME model indicates that the country is currently seeing about 765 daily deaths from Covid-19, but that number could jump to 3,000 daily deaths by late December.

Here's a look at where cases are increasing across the country:

Twenty students have tested positive for Covid-19 at Pace University's Westchester, New York campus, 18 of whom live in the same dormitory, according university spokesperson Marie Boster.

Westchester County required all students to quarantine for two weeks who lived in or had recently left Alumni Hall, the release added.

Alumni Hall students still at the university are required to quarantine there, while those who have recently gone home are required to self-quarantine at home.

"We are continuing the rigorous disinfecting and cleaning of our facilities. Faculty will work to accommodate the remote learning needs of all Alumni Hall students,” McKinstry said. 

Apart from those who have tested positive, their close contacts, or residents of the hall, Pleasantville campus students are continuing a mix of in-person and remote classes, Boster said.

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.
