Public health organizations track the spread of coronavirus and use graphs and charts to visualize the data. WSJ’s Brianna Abbott explains what to look for in the data to understand how the virus is impacting your community.

Researchers have run numerous military-style simulations to predict the consequences of fictitious viral outbreaks. We discuss how these simulations work, what recommendations come out of them and if any of these warnings have been heeded.

28:50 The latest coronavirus research papers
Benjamin Thompson takes a look through some of the key coronavirus papers of the last few weeks.
From Scientific American (June 23, 2020):
In 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.

From the Wall Street Journal (June 16, 2020):
Health agencies have so far identified respiratory-droplet contact as the major mode of Covid-19 transmission. These large fluid droplets can transfer virus from one person to another if they land on the eyes, nose or mouth. But they tend to fall to the ground or on other surfaces pretty quickly.
Some researchers say the new coronavirus can also be transmitted through aerosols, or minuscule droplets that float in the air longer than large droplets. These aerosols can be directly inhaled.
Sufficient ventilation in the places people visit and work is very important, said Yuguo Li, one of the authors and an engineering professor at the University of Hong Kong. Proper ventilation—such as forcing air toward the ceiling and pumping it outside, or bringing fresh air into a room—dilutes the amount of virus in a space, lowering the risk of infection.
Another factor is prolonged exposure. That’s generally defined as 15 minutes or more of unprotected contact with someone less than 6 feet away, said John Brooks, the Centers for Disease Control and Prevention’s chief medical officer for the Covid-19 response. But that is only a rule of thumb, he cautioned. It could take much less time with a sneeze in the face or other intimate contact where a lot of respiratory droplets are emitted, he said.
From the John A. Hartford Foundation:
While the benefits of telehealth are myriad and more apparent than ever, our survey revealed that 41% of older adults did not see telehealth as living up to the in-person experience. Providers must optimize the technology so that it caters to the less tech-savvy patient and caregivers—especially, if it is their only means of accessing health care—so that it replicates the in-person visit as close as possible.
A survey we recently conducted shows that more than half of US adults age 70 and older (55%) experienced a disruption in their medical care during the first month of social distancing due to COVID-19. These older adults were most likely to delay primary or preventive care, and that’s alarming. Even more worrying, 15% of older adults put off essential medical treatment because of the pandemic. We don’t need medical degrees to know that delaying necessary care does not make the outcomes better.
As older adults continue to delay getting needed care, the problem will compound—increasing pent-up demand for services will ultimately vex health systems as patients’ conditions worsen. We think about the 4Ms of age-friendly care – what Matters, Medication, Mentation and Mobility – and how the pandemic may be delaying the assessments and interventions needed to prevent medication errors or to preserve cognitive and functional status.
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.
