Temperature scanners aren’t good at telling who has COVID-19 – here’s how to fix that

Skin temperature isn't a reliable measure of whether someone has a fever, furthermore infected people don't always have a fever and forehead temperature is not the most reliable measure! Scans should instead focus on other parts of the body.

Duke study highlights importance of broad asymptomatic testing

A new study on Duke University’s coronavirus testing and surveillance strategy highlights the importance of widespread testing of asymptomatic individuals to prevent transmission and provides support for the feasibility of a pooled testing approach, in which multiple samples are combined in a single test.

Testing COVID-19 T cells instead of antibodies more accurately finds past infections

Most tests to determine if somebody has already been infected with COVID-19 check for antibodies, but a new study in Italy found that those tests are much less accurate than a new type that looks for a type of immune cell called a T cell.

Trump said Covid-19 testing ‘creates more cases.’ We did the math

A new STAT analysis of testing data for all 50 states and the District of Columbia, however, shows with simple-to-understand numbers why Trump’s claim is wrong. In only seven states was the rise in reported cases from mid-May to mid-July driven primarily by increased testing. In the other 26 states — among the 33 that saw cases increase during that period — the case count rose because there was actually more disease.

How to understand your coronavirus test results, from swabs to antibodies

Experts say testing is a vital component to controlling the outbreak, but one test result still isn’t a green light to visit vulnerable friends or family members. The nature of covid-19, the time it takes for someone to develop symptoms and the varied ways the virus affects people make each test a snapshot in time more than a definitive answer.

Can we detect COVID-19 by analysing speech signals?

You know how people often just 'sound sick'? Researchers are investigating just that. By processing speech recordings of people infected with Covid-19 but not showing symptoms, researchers found evidence of vocal biomarkers, or measurable indicators, of the disease.

Fever checks can’t catch all Covid-19 cases. Smell tests might help

Unfortunately, temperature checks could well join the long list of fumbled responses to the pandemic, from the testing debacle to federal officials’ about-face on masks. Because many contagious people have no symptoms, using temperature checks to catch them is like trying to catch tennis balls in a soccer net: way too many can get through.

Coronavirus tests, unpredictable pricing

Two Friends in Texas Were Tested for Coronavirus The emergency room charged Mr. Harvey $199 in cash. Ms. LeBlanc, who paid with insurance, was charged $6,408. “I assumed, like an idiot, it would be cheaper to use my insurance than pay cash right there,” Ms. LeBlanc said. “This is 32 times the cost of what my friend paid for the exact same thing.”

Prevalence of Asymptomatic SARS-CoV-2 Infection

A new analysis from Scripps Research found 30-40% of people with coronavirus are asymptomatic, but that factor doesn’t mean they are immune from impacts of the disease. Research suggests patients who don’t show any symptoms may still suffer internal organ damage, including lung abnormalities.

Scanning for answers to a pandemic

The greater Seattle Coronavirus Assessment Network—or SCAN—is a first-of-its-kind disease surveillance platform for COVID-19 that allows participants to use a self-swab test to collect their own nasal samples and send them to a lab without leaving home. As a surveillance program, SCAN’s goal isn’t to test every person or serve as a replacement for medical care.

In the U.S., the most likely scenario for widespread, tech-enabled contact tracing lies with work done by Google and Apple.

The Trump administration’s goal of conducting 2 million tests a week is below what most experts say is needed to adequately track the virus, and that plan won’t be in place until at least the end of May.
