Coronavirus Update: State Of The Pandemic After Six Months (Nature Podcast)

Coronapod ReportWe take a look back over the past six months of the pandemic, and discuss how far the world has come. It’s been a period of turmoil and science has faced an unprecedented challenge. What lessons can be learned from the epidemic so far to continue the fight in the months to come?

Also in this episode:

12:55 Unanswered questions

After months of intensive research, much is known about the new coronavirus – but many important questions remain unanswered. We look at the knowledge gaps researchers are trying to fill.

Nature Medicine: Real-time tracking of self-reported symptoms to predict potential COVID-19

20:36 How has lockdown affected fieldwork?

The inability to travel during lockdown has seriously hampered many researchers’ ability to gather fieldwork data. We hear from three whose work has been affected, and what this means for their projects.

Top Daily News Podcast: Economic Recovery, Covid-19 Surge & Virtual Democratic Convention

Axios TodayThe consensus among economists is that the U.S. recovery will most likely be something in between a V and a W — a sharp drop, a relatively small bounce back, and then a long period of slow growth.

  • Time to pay attention again: The coronavirus surge is real, and it’s everywhere in the United States.
  • And Axios co-founder Mike Allen tells us what to expect at the virtual Democratic National Convention in Milwaukee.

Guests: Axios’ Felix Salmon, Sam Baker, and Mike Allen.

Post-Covid Cities: “Fear In An Elevator” (CityLab)

As offices and businesses around the world slowly begin to reopen, the spotlight turns to one of the most traditionally uninteresting forms of transportation: the elevator. Modern cities are intrinsically reliant on these vertical transports which, in light of the global pandemic, can carry new risk factors.

Covid-19: “Superspreading Events” Responsible For Up To 80% Of Infections

From Scientific American (June 23, 2020):

Scientific AmericanIn fact, research on actual cases, as well as models of the pandemic, indicate that between 10 and 20 percent of infected people are responsible for 80 percent of the coronavirus’s spread.

Researchers have identified several factors that make it easier for superspreading to happen. Some of them are environmental.

  • Poorly ventilated indoor areas seem especially conducive to the virus’s spread – A preliminary analysis of 110 COVID-19 cases in Japan found that the odds of transmitting the pathogen in a closed environment was more than 18 times greater than in an open-air space.
  • Places where large numbers of people congregate – As a group’s size increases, so does the risk of transmitting the virus to a wider cluster. A large group size also increases the chance that someone present will be infectious.
  • The longer a group stays in contact, the greater the likelihood that the virus will spread among them – The benchmark used for risk assessment in her contact-tracing work is 10 minutes of contact with an infectious person, though the CDC uses 15 minutes as a guideline.
  • Some activities seem to make it easier to spread respiratory gunk – Speech emits more particles than normal breathing. And emissions also increase as people speak louder. Singing emits even more particles, which may partially explain the superspreader event at the Washington State choir practice. Breathing hard during exercise might also help the spread of COVID-19.

New Science Podcasts: Coronavirus Contact Tracing Apps, Sea Otters

science-magazine-podcastsStaff Writer Kelly Servick joins host Sarah Crespi to talk about the ins and outs of coronavirus contact tracing apps—what they do, how they work, and how to calculate whether they are crushing the curve. 

Edward Gregr, a postdoctoral fellow at the Institute for Resources, Environment, and Sustainability at the University of British Columbia, Vancouver, talks with Sarah about the controversial reintroduction of sea otters to the Northern Pacific Ocean—their home for centuries, before the fur trade nearly wiped out the apex predator in the late 1800s. Gregr brings a unique cost-benefit perspective to his analysis, and finds many trade-offs with economic implications for fisheries For example, sea otters eat shellfish like urchins and crabs, depressing the shellfishing industry; but their diet encourages the growth of kelp forests, which in turn provide a habitat for economically important finfish, like salmon and rockfish.

Healthcare: “Rethinking How Hospitals Operate”

From the Wall Street Journal (June 8, 2020):

“We have to operate a hospital within a hospital, taking care of the needs for patients who have had strokes or a newborn delivery or need surgery while dealing with an otherwise healthy 35-year-old who picked up Covid-19 at a social event,” says James Linder, chief executive of Nebraska Medicine…

Rethinking The Hospital for the Next Pandemic - Wall Street Jouranl - June 8 2020For instance, more hospitals are remotely triaging and registering patients before they even arrive. Clinicians can consult with patients from their home via telemedicine to help determine how sick they are and if they need to come to the ER at all. From there, admissions are made with as little contact with staff or other patients as possible.

Hospitals are rethinking how they operate in light of the Covid-19 pandemic—and preparing for a future where such crises may become a grim fact of life.

Rethinking The Hospital for the Next Pandemic - Wall Street Jouranl - June 8 2020 - Illustration by Justin MetzWith the potential for resurgences of the coronavirus, and some scientists warning about outbreaks of other infectious diseases, hospitals don’t want to be caught flat-footed again. So, more of them are turning to new protocols and new technology to overhaul standard operating procedure, from the time patients show up at an emergency room through admission, treatment and discharge.

Top New Science Podcasts: Higher Covid-19 Severity In Men, Bacteria Tracking

science-magazine-podcastsFirst up this week, Staff Writer Meredith Wadman talks with host Sarah Crespi about how male sex hormones may play a role in higher levels of severe coronavirus infections in men. New support for this idea comes from a study showing high levels of male pattern baldness in hospitalized COVID-19 patients.

Next, Jason Qian, a Ph.D. student in the systems biology department at Harvard Medical School, joins Sarah to talk about an object-tracking system that uses bacterial spores engineered with unique DNA barcodes. The inactivated spores can be sprayed on anything from lettuce, to wood, to sand and later be scraped off and read out using a CRISPR-based detection system. Spraying these DNA-based identifiers on such things as vegetables could help trace foodborne illnesses back to their source. Read a related commentary piece.

Podcasts Interviews: The Diagnosis And Early Treatment Of Covid-19

In this audio interview conducted on June 3, 2020, the editors discuss two new studies: one comparing test swabs collected by health care workers with swabs collected by the patients themselves and one assessing hydroxychloroquine treatment in people who had been exposed to Covid-19 but weren’t yet ill.

The continuing spread of SARS-CoV-2 remains a Public Health Emergency of International Concern. What physicians need to know about transmission, diagnosis, and treatment of Covid-19 is the subject of ongoing updates from infectious disease experts at the Journal.
