Coronavirus in Minnesota: 12 more deaths; hospitalizations on the rise – MinnPost

Posted: April 2, 2021 at 10:39 am

MinnPost provides updates on coronavirus in Minnesota Sunday through Friday. The information is published following a press phone call with members of the Walz administration or after the release of daily COVID-19 figures by the Minnesota Department of Health.

Here are the latest updates from April 1, 2021:

Twelve more Minnesotans have died of COVID-19, the Minnesota Department of Health said Thursday, for a total of 6,860.

Of the people whose deaths were announced Thursday, five were in their 80s, two were in their 70s, four were in their 60s and one was in their 40s. Four of the 12 people whose deaths announced Thursday were residents of long-term care facilities.

MDH also said Thursday there have been 521,667 total cases of COVID-19 in Minnesota. That number is up 2,138 from the total announced on Wednesday and is based on 43,117 new tests. The seven-day positive case positivity rate, which lags by a week, is 5.4 percent. That rate has been increasing for weeks and is above a 5-percent threshold state officials consider a concerning sign of disease spread.

As of Tuesday, the most recent day of data available, 1,682,545 Minnesotans, or 30.2 percent of the population, have received at least one dose of a COVID-19 vaccine. Thats up 24,369 from data reported the day prior.

Fairview is now vaccinating anyone 50+, those with certain disabilities or health conditions and communities of color. More information can be found here.

Hospitalizations continue to rise. The most recent data available show 105 Minnesotans are hospitalized in intensive care with COVID-19, which is up from 102 in data reported Wednesday and up from 93 last Thursday. Data show 330 people are in the hospital with COVID-19 not in intensive care, up from 309 reported on Wednesday and 239 reported the week prior. The last time Minnesota had more than 100 people in the ICU with COVID-19 was late January, and the hospitalization levels are similar to last September, when a deadly surge in the virus was starting.

Minnesota health officials continue to report new cases of more contagious COVID-19 variants in the state.

While MDH and its partners dont check every sample for evidence its a variant, they have been increasing surveillance and targeting clusters of cases or instances where people have traveled to measure spread of the variants. The B117 variant is believed to be 50 percent more contagious and resulted in a death rate 64 percent higher than other COVID-19 strains.

State Epidemiologist Dr. Ruth Lynfield told reporters Thursday the state has found 943 cases of the COVID-19 variant known as B117, which was first identified in the U.K. This is up from 479 cases last Tuesday.

Lynfield said that in 2,600 COVID-19 positive samples at one testing lab between March 22 and March 27, between 54-66 percent were found to be B117. In roughly 1,800 positive samples between March 16 and 20, about 50-65 percent were found to be caused by B117.

Among the 943 identified cases of B117, Lynfield said 36 people have been hospitalized and four people have died.

The state has identified 214 cases of variant first identified in California, which is also thought to be more contagious. Of those cases, four people have been hospitalized and two have died.

Health officials believe the 15 million ruined Johnson & Johnson vaccine doses at a Baltimore plant wont immediately affect Minnesotas allocation of the vaccine, said Kris Ehresmann, MDHs infectious disease director.

The state has been expecting an increase in J&J doses over the next several weeks. The vaccine is manufactured elsewhere in addition to the Baltimore plant. At this point, it would seem that it will not affect Minnesotas doses but we are waiting for final confirmation from CDC, Ehresmann said.

Lynfield told reporters that people infected with COVID-19 should ask their doctor if theyre a good fit to use monoclonal antibodies as a treatment. The drug, which is given via intravenous infusion, has been shown in studies to reduce hospitalizations among people at high risk of a severe case of COVID-19.

Lynfield said Minnesota has a supply of more than 9,000 doses and can infuse more than 2,000 people each week. It must be administered within 10 days of when symptoms of COVID-19 begin. The earlier the better.

Not all health care providers have antibody treatments, however. Patients or health care providers can get a referral to where they can get antibody treatments through the states Minnesota Resource Allocation Platform. People need to complete a screening questionnaire on the site.

Current health guidance says that people who are vaccinated should still not attend large gatherings with unvaccinated people, even though theyre at less risk of severe disease.

Ehresmann said that guidance is because health officials did not know if fully vaccinated people could still be carriers of the disease while not developing symptoms, and may spread the disease to others who arent protected by vaccines yet.

New CDC research suggests vaccinated people arent asymptomatic carriers. Ultimately, Ehresmann said she expects guidance to change accordingly. But she said until there is a larger body of data and evidence, the rules around masking and distancing should still be followed as a safety net to protect others.

Some variants of COVID-19 are also thought to better evade immunity given through vaccination.

Undetected Coronavirus Variant Was in at Least 15 Countries Before its Discovery – UT News – UT News | The University of Texas at Austin

Posted: at 10:39 am

AUSTIN, Texas A highly contagious SARS-CoV-2 variant was unknowingly spreading for months in the United States by October 2020, according to a new study from researchers with The University of Texas at AustinCOVID-19 Modeling Consortium. Scientists first discovered it in early December in the United Kingdom, where the highly contagious and more lethal variant is thought to have originated. The journalEmerging Infectious Diseases, whichhas published an early-release version of the study, provides evidence that the coronavirus variant B117 (501Y) had spread across the globe undetected for months when scientists discovered it.

By the time we learned about the U.K. variant in December, it was already silently spreading across the globe, said Lauren Ancel Meyers, the director of the COVID-19 Modeling Consortium at The University of Texas at Austin and a professor of integrative biology. We estimate that the B117 variant probably arrived in the U.S. by October of 2020, two months before we knew it existed.

Analyzing data from 15 countries, researchers estimated the chance that travelers from the U.K. introduced the variant into 15 countries between Sept. 22 and Dec. 7, 2020. They found that the virus variant had almost certainly arrived in all 15 countries by mid-November. In the U.S., the variant probably had arrived by mid-October.

This study highlights the importance of laboratory surveillance, Meyers said. Rapid and extensive sequencing of virus samples is critical for early detection and tracking of new variants of concern.

In conjunction with the papers publication, consortium members developed a new tool that decision-makers anywhere in the United States can use in planning for genetic sequencing that helps to detect the presence of variants. To help the U.S. expand national surveillance of variants, the new onlinecalculatorindicates the number of virus samples that must be sequenced in order to detect new variants when they first emerge. For example, if the goal is to detect an emerging variant by the time it is causing 1 out of every 1,000 new COVID-19 infections, approximately 3,000 SARS-CoV-2 positive specimens per week need to be sequenced.

Health officials are looking for better ways to manage the unpredictability of this virus and future variants, said Spencer Woody, a postdoctoral fellow at the UT COVID-19 Modeling Consortium. Our newcalculatordetermines how many positive SARS-CoV-2 specimens must be sequenced to ensure that new threats are identified as soon as they start spreading.

He explained that the calculator has a second feature. It also helps labs figure out how quickly they will detect new variants, given their current sequencing capacity.

We created this tool to support federal, state and local health officials in building credible early warning systems for this and future pandemic threats, Meyers said.

More detailed information on the calculator ishere.

In addition to Meyers, authors of the Emerging Infectious Disease paper are Zhanwei Du, Bingyi Yang, Sheikh Taslim Ali, Tim K. Tsang, Songwei Shan, Peng Wu, Eric H.Y. Lau and Benjamin J. Cowling of the WHO Collaborating Centre for Infectious Disease Epidemiology and Control in Hong Kong and Lin Wang of the University of Cambridge.

The research was funded by Hong Kongs Health and Medical Research Fund, the National Institutes of Health and the Centers for Disease Control and Prevention.

Meyersholds the Denton A. Cooley Centennial Professorship at The University of Texas at Austin.

Fewer Ohio counties on red alert for coronavirus, but statewide case rate is increasing, health department re – cleveland.com

Posted: at 10:39 am

CLEVELAND, Ohio - Fifty-one Ohio counties remain on red alert for concern of coronavirus spread, the state announced Thursday, as the case rate overall in Ohio has been increasing this spring after a sharp decline through most of the winter.

There were 167.1 known new cases per 100,000 people over the last two weeks, up from the rate of 146.9 per 100,000 reported a week ago, and moving away from Gov. Mike DeWines stated goal of 50 before he will lift his health orders that range from mandated masks in public to limited crowds at entertainment venues.

The rate is based on when people noticed symptoms, not when their cases were reported by the state, which could be days or weeks later. And it excludes incarcerated individuals.

We have in fact seen an increase in COVID-19 activity in Ohio that mirrors what we have seen nationally, said Dr. Bruce Vanderhoff, chief medical officer for the Ohio Department of Health, noting that new strains of the virus have accounted for 80% of Ohios new cases. Here in Ohio variant activity continues to rise.

Vanderhoff noted a sharper increase in new cases along the northern border with Michigan, which has encountered one the nations sharpest increases.

What we have to do is stay on defense by wearing a mask, DeWine said. The other thing is the vaccinations.

The state reported close to 3.5 million Ohioans have received at least their first dose, with all doses completed for about 2 million.

This is a race, DeWine said in encouraging people to get vaccinated. We cannot vaccinate fast enough.

But while the case rate statewide has increased, the number of counties on red alert has declined. A week ago 55 counties were listed on red alert in the states coronavirus advisory system. This compared with 66, 76, 80 and 84 red alert counties the previous four weeks.

Among the red counties are Cuyahoga and each of the six adjacent counties in Greater Cleveland.

Level 3 red alert, according to the health department, means there remains a public emergency for increased exposure and spread, and that people should exercise a high degree of caution. The alert system takes into account more than just new case rates, but also trends in hospitalizations, doctor visits and emergency room visits related to COVID-19.

But for the last several weeks the focus has moved away from the alert map and to the Thursday updates for new cases over the previous two weeks. This is because DeWine on March 4 announced he would condition removal of his health orders to the rate dropping to 50 cases per 100,000.

At the time of his announcement, rates were going down sharply. But they have reversed. The last two updates to the rate, reported each Thursday, mark the only week-to-week increases this year.

Ohio was last below 50 per 100,000 in June. The rate was a record high of 845.5 in mid-December.

Ohio's coronavirus case rate per 100,000 residents, excluding incarcerated individuals, as reported by the Ohio Department of Health. The latest report released on Thursday, April 1, was based on data available through Wednesday, March 31.Rich Exner, cleveland.com

Level 2 orange alert (32 counties): Adams, Allen, Ashtabula, Auglaize, Brown, Columbiana, Coshocton, Darke, Fayette, Fulton, Gallia, Guernsey, Harrison, Hocking, Jackson, Knox, Lawrence, Logan, Meigs, Monroe, Morrow, Noble, Paulding, Preble, Putnam, Scioto, Shelby, Tuscarawas, Van Wert, Vinton, Wayne and Williams.

Level 1 yellow alert (5): Carroll, Clinton, Holmes, Mercer and Morgan.

Case rates by county range from 18.2 per 100,000 in Holmes County to 317 per 100,000 in Clark County. Just four counties are below the target rate of 50 per 100,000 - Homes, Mercer (36.4), Morgan (41.4) and Carroll (44.6).

In Greater Cleveland, the case rate is highest in Summit County:

* Cuyahoga: 194.3 per 100,000 this week versus 167, 162 and 190.6 in the updates each of the previous three weeks.

* Geauga: 123.9 versus 106.8, 122.8 and 147.4 the last three weeks.

* Lake: 136.9 versus, 126, 149.5 and 160.8.

* Lorain: 198.8 versus 148.5, 143 and 159.1.

* Medina County: 178 versus 190.8, 206.4 and 189.7.

* Portage County: 211.1 versus 186.5, 164.3 and 155.7.

* Summit County: 267.3 versus 219, 203.7 and 184.3.

Heres a closer look at the advisory system introduced in early July. Alert levels are determined by the number of warning benchmarks met. But once a county reaches red alert, it does not drop unless its rate of new cases also drops below 100 per 100,000 over two weeks.

* 1. New cases - Alert triggered when there are 50 new cases per cases 100,000 residents over the last two weeks.

* 2. Increase in new cases - Alert triggered by an increase in cases for five straight days at any point over the last three weeks. This is based on the date of onset of symptoms, not when the cases are reported.

* 3. Non-congregate living cases - Alert triggered when at least 50% of the new cases in one of the last three weeks have occurred in outside congregate living spaces such as nursing homes and prisons.

* 4. Emergency rooms - Alert triggered when there is an increase in visits for COVID-like symptoms or a diagnosis for five straight days at any point in the last three weeks.

* 5. Doctor visits - Alert triggered when there is an increase in out-patient visits resulting in confirmed cases or suspected diagnosis for COVID-19 for five straight days at any point in the last three weeks.

* 6. Hospitalizations - Alert triggered when there is an increase in new COVID-19 patients for five straight days at any point over the last three weeks. This is based on the county or residence, not the location of the hospital.

* 7. Intensive Care Unit occupancy - Alert triggered when ICU occupancy in a region exceeds 80% of total ICU beds and at least 20% of the beds are being used for coronavirus patients for at least three days in the last week.

Rare ‘Breakthrough’ Cases of COVID-19 Occurring in Vaccinated People – Healthline

Posted: at 10:39 am

The number of people being vaccinated against COVID-19 is increasing every day in the United States. On average, more than 2.8 million people are being vaccinated against the disease every day.

While vaccines are a vital part of the path out of this pandemic, theyre not fail-proof. In rare cases, officials are reporting breakthrough infections.

In these rare cases, people can still develop COVID-19 despite vaccination.

But experts say these rare cases are expected as more people get vaccinated, and they may ultimately help officials stamp out the coronavirus.

A breakthrough case is when someone develops an illness despite already being fully vaccinated.

This isnt a reason to avoid getting vaccinated. Theres no vaccine that can provide 100 percent immunity against any disease.

Experts say these rare breakthrough COVID-19 cases will give experts a way to determine the extent to which COVID-19 vaccines work and what coronavirus variants may be causing these cases despite vaccination.

I dont think we need to be overly concerned as of yet, said Dr. William Schaffner, professor of preventive medicine and infectious diseases at Vanderbilt University in Nashville, Tennessee.

We should know that these vaccines are not perfect, and under ideal circumstances they provide up to 95 percent chance of protection. Not everyone, particularly those that are frail and partly immunocompromised, may not even get 95 percent protection, he said.

Additionally, while a COVID-19 vaccine isnt completely protective against symptoms, experts stress the vaccine is extremely effective at preventing the most serious complications that lead to hospitalization and death.

In clinical trials, people given COVID-19 vaccines were not hospitalized even in rare cases of developing the disease.

Fully vaccinated people have some immunity against COVID-19, particularly against the strain of the coronavirus the vaccine was made for.

And while COVID-19 vaccines have some protection against several of these variants, it doesnt give full immunity particularly in people who may be immunocompromised.

Most people will mount a strong immunologic response. But individuals who are highly immunocompromised may have a more blunted response, and these individuals need to remain careful even if they are vaccinated, said Dr. David Hirschwerk, attending physician in the department of infectious diseases at Northwell Health in Manhasset, New York.

All of this is expected.

People who are immunocompromised dont always mount the strongest response to vaccines.

And even people who arent immunocompromised can still be vulnerable to breakthrough cases.

Experts say researching these breakthrough cases will be key in understanding the real-world effectiveness of COVID-19 vaccines and the likelihood a coronavirus variant may be able to evade vaccine protection.

Scientists can study any trends and predictors of which individuals may be less protected from vaccination, Hirschwerk said.

Researchers will be studying which groups of people get these breakthrough cases, how frequently they occur, where they occur, and the genetic sequencing of breakthrough variants to figure out how to best fight back against COVID-19.

Schaffner pointed out that by studying breakthrough cases, scientists can monitor for troubling signs of rising variants.

By understanding variants we are able to understand how commonly these phenomena are occurring, Schaffner said of breakthrough cases. And if they are preferentially being caused by variants, we may need a booster dose that protects against those strains.

The Centers for Disease Control and Prevention (CDC) is continuing to assess how COVID-19 vaccines are working in real-world conditions.

Experts will also closely watch what happens when vaccinated people develop COVID-19 and what their symptoms are like.

The majority of these will very likely be of people with mild to moderate symptoms, Hirschwerk told Healthline.

Breakthrough infections are an expected outcome in any vaccination process. No vaccines is 100 percent fail-proof.

These breakthrough cases arent a reason to panic. Instead, experts say they show why we still need to practice mask wearing, handwashing, and physical distancing measures while scientists learn how and why these cases are occurring.

And most importantly, these breakthrough cases shouldnt deter the public from getting vaccines, as they do work.

COVID-19 vaccines remain extremely effective in preventing severe and life threatening cases of COVID-19.

More Mainers are booking flights as the coronavirus rages on – NewsCenterMaine.com WCSH-WLBZ

Posted: at 10:39 am

Maine airport officials say passengers may soon be required to show proof they've been vaccinated to travel by plane.

BANGOR, Maine More Mainers are traveling again, especially by air.

Travel at the Portland International Jetport is down 50-60 percent from this time two years ago. Traffic at the Bangor Internal Airport was down to about 65 percent in February compared to the same month last year. Despite this, traffic is steadily picking up.

According to the Transportation Security Administration, 1.5 million Americans traveled on a plane this past Sunday alone. This is the busiest travel day for the country's airports sinceMarch 12, 2020, when more than 1.7 million people were screened.

A lot of people are coming in, theyll sit at my desk and the first thing theyll say is, were vaccinated. Were ready to travel,' said Mary Ellen Lessard, travel agent at AAA Northern New England.

Lessard added, many folks are looking for a getaway to Maine and state parks around the country.

"I think people are just housebound and they want to get out. One of the important things too is all the airlines are removing their reissue fees. If [passengers] need to change [their flight] they can do so without a hefty fee, said Lessard.

Although there is no official mandate for showing proof youve received a COVID-19 vaccine to travel here in the state, that might change.

There are a lot of conversations happening within the industry on how do we streamline this so that a customer can enter their information once and have it work for all airlines, said Portland International Jetport assistant director Zachary Sundquist.

Airport officials are also stressing the importance of keeping up to date on travel restrictions.

Were directing people to the CDC and their travel alerts, and also to the particular state [passengers are] going to to get the information because it does change on a fairly regular basis," said Aimee Tibeaude, Bangor International Airport marketing and business development manager.

Tibeaude also wants folks to remember that real ID compliance for Mainers starts in October. Those planning to fly that month or anytime after will need a real ID or passport.

‘We’re hacking the process of creating qubits.’ How standard silicon chips could be used for quantum computing – ZDNet

Posted: at 10:38 am

Quantum Motion's researchers have shown that it is possible to create a qubit on a standard silicon chip.

Forget about superconducting circuits, trapped ions, and other exotic-sounding manufacturing techniques typically associated with quantum computing: scientists have now shown that it is possible to create a qubit on a standard silicon chip, just like those found in any smartphone.

UK-based start-up Quantum Motion has published the results of its latest experiments, which saw researchers cooling down CMOS silicon chips to a fraction of a degree above absolute zero (-273 degrees Celsius), enabling them to successfully isolate and measure the quantum state of a single electron for a whole nine seconds.

The apparent simplicity of the method, which taps similar hardware to that found in handsets and laptops, is striking in comparison to the approaches adopted by larger players like IBM, Google or Honeywell, in their efforts to build a large-scale quantum computer.

To create and read qubits, which are the building blocks of those devices, scientists first have to retain control over the smallest, quantum particles that make up a material; but there are different ways to do that, with varying degrees of complexity.

IBM and Google, for example, have both opted for creating superconducting qubits, which calls for an entirely new manufacturing process; while Honeywell has developed a technology that individually traps atoms, to let researchers measure the particles' states.

These approaches require creating new quantum processors in a lab, and are limited in scale. Intel, for example, hascreated a 49-qubit superconducting quantum processorthat is about three inches square, which the company described as already "relatively large", and likely to cause complications when it comes to producing the million-qubit chips that will be required for real-world implementations at commercial scale.

With this in mind, Quantum Motion set off to find out whether a better solution could be found in proven, existing technologies. "We need millions of qubits, and there are very few technologies that will make millions of anything but the silicon transistor is the exception," John Morton, professor of nanoelectronics at University College London (UCL) and co-founder of Quantum Motion, tells ZDNet.

"So rather than scaling up a new approach, we looked at whether we could piggy back off of that capability and use these tools to build something similar, but with qubits."

As Morton explains, when a transistor is switched on, it sucks in a bunch of electrons that enable current to pass. Cooling down the chip to a low temperature, however, slows down this process, and enables researchers to watch the electrons as they enter the transistor one by one "Like watching sheep walking into a field," says Morton. Instead of letting all of the particles in, the researchers allowed only one electron to enter; and once isolated, the particle could be used and measured as a qubit.

"We're hacking the process of creating qubits, so the same kind of technology that makes the chip in a smartphone can be used to build quantum computers," says Morton.

The significant advantage that silicon chips offer over alternative quantum approaches is scale. The qubit density that can be obtained with a silicon chip is effectively much higher due to the small size of electrons; according to Morton, this would let a single chip pack millions of qubits, where a superconducting quantum computer could require an entire building for the same yield.

What's more, silicon chips are now sitting on decades-worth of tweaking and development, meaning that quantum devices could rely on established processes and fabrication plants. This would fast-track the development of quantum processors, while bringing down prices.

In other words, rather than starting from scratch, Quantum Motion proposes taking the best of what is already out there. "Plus, every time the silicon industry makes an advance, you could benefit from in the qubit technology," says Morton.

As promising as the experiment may be, it is still very early days for silicon-based quantum computing: Morton and his team, for now, have only isolated and measured the state of a single electron. In a next step, the researchers are planning on creating a quantum gate by entangling two qubits together on the chip.

Quantum Motion's findings, rather, should be seen as a blueprint for producing quantum chips more efficiently, by leveraging existing manufacturing processes.

The start-up's findings are likely to grab the attention of larger competitors. Intel, for one, has shown growing interest for the opportunities that silicon chips present for quantum. The Santa Clara giant has partnered with QuTech, a Netherlands-based startup, to explore the potential of silicon spin qubits.

Cleveland Clinic to be First U.S. Site of IBM "Quantum Computer" for Advanced Healthcare Research – Cleveland Scene

Quantum computing can get pretty esoteric in a hurry, so we won't bother trying to hash it out beyond the basic premise, which is that there are some problems too complex for even the world's biggest and most sophisticated supercomputers. Quantum computers deal with the sorts of problems for which there's an almost incalculable amount of data, and in theory can crunch all that data in a hurry.

"Universal quantum computers" this is from IBM "leverage the quantum mechanical phenomena of superposition and entanglement to create states that scale exponentially with number of qubits, or quantum bits."

Evidently, issues surrounding the world's pathogens, including the ominous horizon of viral global pandemics, are ripe for investigation via this sort of big data computing. The so-called "Discovery Accelerator" program between the Clinic and IBM aims to do just that. The whole point, via the press materials, is to accelerate the pace of discovery in medical research.

As part of this partnership, IBM announced that it willinstall its first U.S.-based private sector "Quantum System One" on Cleveland Clinics campus in Cleveland. In a press release, IBM said it also planned to install "the first of IBMs next-generation 1,000+ qubit quantum systems at a client facility," also in Cleveland, in the coming years.

Much of quantum computing remains entirely theoretical, and the costs associated with the construction and maintenance of these high-tech machines remain under wraps, but if successful these IBM machines will facilitate ongoing research in healthcare, and are being touted as key ingredients for medical and pharmaceutical breakthroughs. Like dozens of other fashionable partnerships and local real estate development projects in recent years, this, too, is being celebrated as an opportunity to put Cleveland on the map.

The partnership comes, however, after both Cleveland and IBM have had disappointing forays into the arenas of big data and artificial intelligence to solve social ills.

In Cleveland, the Unify Project, a mercurial high-tech nonprofit that was meant to use big data and AI to end poverty (or something), crumbled without ever producing much of anything. It is now Unify Labs, or perhaps Unify Jobs, and appears to have pivoted into an equity and inclusion-focused job board.

For its part, IBM recently put Watson Healthup for sale, the Wall Street Journal reported. This was the company's "audacious" plan to help doctors diagnose and cure cancer, among other things, with artificial intelligence. A report in the medical journal STAT found that mismanagement, rapid turnover via layoffs and departures and a culture where marketing was prioritized over science led to the internal combustion of the multibillion-dollar enterprise.

But quantum computing! In an innovation district! That's something else entirely, and something that the overwhelmingly impoverished residents in the zip codes surrounding the Clinic's campus will no doubt enthusiastically get behind.

Through this innovative collaboration, we have a unique opportunity to bring the future to life, said Tom Mihaljevic, President and CEO of the Cleveland Clinic, in a press release. These new computing technologies can help revolutionize discovery in the life sciences. The Discovery Accelerator will enable our renowned teams to build a forward-looking digital infrastructure and help transform medicine, while training the workforce of the future and potentially growing our economy.
