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.

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.

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.

U.S. Coronavirus Testing Could Fail Again

The United States is once again at risk of outstripping its COVID-19 testing capacity, an ominous development that would deny the country a crucial tool to understand its pandemic in real time.

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.

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.
