Rapid screening tests that prioritize speed over accuracy could be key to ending the coronavirus pandemic

Broad access to testing is one of the most powerful tools to keep the COVID-19 pandemic under control until there’s an effective vaccine in use. Diagnostic testing, which is used in medical settings to determine whether someone is infected with the coronavirus, is costly, slow and overstretched in the U.S. But that’s not the only type of test that can be used. I study public health policy to combat infectious disease epidemics. To slow the spread of the virus, public health programs need to catch more COVID-19 cases and catch them before they spread. Innovative screening tests offer promise because they are inexpensive, rapid, easily mass produced and don’t require laboratory processing. They can be implemented at large scale for frequent testing in schools, workplaces, airports and even ...

Trillions in coronavirus spending is putting AOC’s favorite economic theory to the test

French philosopher Voltaire famously quipped: “If God did not exist, it would be necessary to invent him.” Something similar can be said of modern monetary theory, also known as MMT, because it may be the economy’s only hope to get through the pandemic. Coined by Australian economist Bill Mitchell and popularized recently by Democrats like Rep. Alexandria Ocasio-Cortez to fund programs such as the Green New Deal, MMT holds that a country with its own currency can spend almost unlimited sums of money. While government spending is normally financed by either taxes or borrowing, MMT suggests that governments can also do this by simply creating money. I’m currently working on a book chapter that examines various economic theories about government debt, including MMT. I believe this theory is...

How to use ventilation and air filtration to prevent the spread of coronavirus indoors

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others. Masks do a decent job at keeping the virus from spreading into the environment, but if an infected person is inside a building, inevitably some virus will escape into the air. I am a professor of mechanical engineering at the University of Colorado Boulder. Much of my work has focused on how to control the transmission of airborne infectious diseases indoors, and I’ve been asked by my own univer...

How COVID-19 might increase risk of memory loss and cognitive decline

Of all frightening ways that the SARS-COV-2 virus affects the body, one of the more insidious is the effect of COVID-19 on the brain. It is now clear that many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell, to delirium, to an increased risk of stroke. There are also longer-lasting consequences for the brain, including myalgic encephalomyelitis /chronic fatigue syndrome and Guillain-Barre syndrome. These effects may be caused by direct viral infection of brain tissue. But growing evidence suggests additional indirect actions triggered via the virus’s infection of epithelial cells and the cardiovascular system, or through the immune system and inflammation, contribute to lasting neurological changes after COVID-19. I am a neuroscientist specializing in...

What the huge COVID-19 testing undercount in the US means

Researchers from the Centers for Disease Control and Prevention and other institutions recently published a study which estimated that the true number of people infected by COVID-19 could be six to 24 times higher than the number of confirmed cases. Melissa Hawkins, professor of public health at American University, explains what this large undercount means and why insufficient data is hampering the U.S.‘s ability to control the pandemic. Melissa Hawkins explains the implications of the COVID-19 testing undercount. What are some reasons for the large disparity between the true number of infected cases and the confirmed case count in the U.S.? We just passed 4 million total confirmed cases and over 150,000 deaths. But those confirmed cases really only tell part of the story since we know th...

Video: Who controls pandemic data?

When the Trump administration ordered hospitals to report COVID-19 data to the Department of Health and Human Services rather than the Centers for Disease Control and Prevention as they had been doing, it provoked worries and criticism from public health experts. The White House said that the HHS system will provide more accurate data faster, but the switch did raise concerns that political considerations would influence what data is reported. Professor of public policy Julia Lane, who recently published the book “Democratizing Our Data: A Manifesto,” explains why public data is vital to public health and democracy in general. What was the main concern over the data? The whole point of having a career civil service running public data systems is that, because they can’t be fired, they hav...

Yes, kids can get COVID-19 – 3 pediatricians explain what’s known about coronavirus and children

We are three pediatric infectious disease specialists who live and work in West Virginia. The West Virginia University health system serves 400,000 children and according to our internal data, to date, 2,520 children up to 17 years of age have been tested for the coronavirus. Sixty-seven of them tested positive and one became sick enough to be admitted to the hospital. We are asked almost daily about children and COVID-19: Do they get COVID-19? Should they attend day care or school, play sports, see friends and attend summer camps? What are the risks to themselves and to others? Based on current research and our own experiences, it would seem that kids 17 years old and younger face little risk from the coronavirus. Nearly all children have asymptomatic, very mild or mild disease, but a s...

Disinformation campaigns are murky blends of truth, lies and sincere beliefs – lessons from the pandemic

The COVID-19 pandemic has spawned an infodemic, a vast and complicated mix of information, misinformation and disinformation. In this environment, false narratives – the virus was “planned,” that it originated as a bioweapon, that COVID-19 symptoms are caused by 5G wireless communications technology – have spread like wildfire across social media and other communication platforms. Some of these bogus narratives play a role in disinformation campaigns. The notion of disinformation often brings to mind easy-to-spot propaganda peddled by totalitarian states, but the reality is much more complex. Though disinformation does serve an agenda, it is often camouflaged in facts and advanced by innocent and often well-meaning individuals. As a researcher who studies how communications technologies...

Random testing in Indiana shows COVID-19 is 6 times deadlier than flu, and 2.8% of the state has been infected

Since day one of the coronavirus pandemic, the U.S. has not had enough tests. Faced with this shortage, medical professionals used what tests they had on people with the worst symptoms or whose occupations put them at high risk for infection. People who were less sick or asymptomatic did not get tested. Because of this, many infected people in the U.S. have not been tested, and much of the information public health officials have about the spread and deadliness of the virus does not provide a complete picture. Short of testing every person in the U.S., the best way to get accurate data on who and how many people have been infected with the coronavirus is to test randomly. I am a professor of health policy and management at Indiana University, and random testing is exactly what we did in ...

Coronavirus numbers confusing you? Here’s how to make sense of them

Turn on the TV news, or look at a news website, and you’ll see charts, graphics, and dashboards that supposedly indicate the latest with COVID-19 – statistics revealing the number of tests, cases, hospitalizations and deaths, along with where they happened and whether they are rising or falling. Different stories are told depending on the dashboard. But one thing is certain: These indicators lag behind the actions we take, or don’t take, on COVID-19. As researchers who focus on public health, we can tell you that a fully accurate, real-time snapshot of the progress of the virus isn’t possible. Some don’t get tested There are many reasons for this. Here’s one: diagnostic testing data are incomplete. Someone infected with COVID-19 must first come in contact with the virus either through the...
