Quest Diagnostics said its average turnaround time for a COVID-19 test is now at "seven or more days," up from four to five days at the end of June. Its testing backlog is getting worse because of the high demand in parts of the country where infection is spreading.

Why it matters: Long backlogs make testing less useful — public health officials need to know what their local situation is like now, not what it was like a week ago. Delays are especially problematic if people who are infected continue to go about their lives while they wait for their results.

Between the lines: Quest told investors Monday that its second-quarter revenue will be down 6%, hovering around $1.83 billion, as coronavirus testing has supplanted other, more lucrative tests that had to be put off.

  • But Quest still expects to register a profit of at least $1.33 per share thanks to $65 million of government bailout funds and high volumes of COVID-19 tests.

Boeing and researchers at the University of Arizona say their experiment with a live virus on an unoccupied airplane proves that the cleaning methods currently used by airlines are effective in destroying the virus that causes COVID-19.

Why it matters: Deep cleaning aircraft between flights is one of many tactics the airline industry is using to try to restore public confidence in flying during the pandemic. The researchers say their study proves there is virtually no risk of transmission from touching objects including armrests, tray tables, overhead bins or lavatory handles on a plane.

The Center for Disease Control and Prevention expanded its definition of who is considered a “close contact” of an individual infected with the coronavirus in a report released Wednesday.

Why it matters: The update is likely to pose challenges for schools, workplaces and other group settings as the U.S. prepares for a third coronavirus wave. It also reinforces the importance of masks in the face of President Trump’s repeated attempts to belittle their efficacy.
