Some states — generally those without major coronavirus outbreaks — are doing enough testing for now, at least according to one metric.

Between the lines: Although the U.S. as a whole still falls far short of where it needs to be on testing, several individual states are testing enough people to put their positive rate at or below 10% of the total number of people tested — an important indicator of whether the state can successfully identify new outbreaks.

The big picture: The World Health Organization has recommended that coronavirus testing should be prolific enough that only 10% or less of the tests come back positive, according to NPR, although some experts say the rate should be even lower.

• That indicates that a large enough testing net is being cast to catch all of the infections in the community, which is key to then stopping the spread of the virus.
• "If you have a very high positive rate, it means that there are probably a good number of people out there who have the disease who you haven't tested," Ashish Jha, director of the Harvard Global Health Institute, recently told the New York Times.

Yes, but: Outbreaks are not static, and states that are testing a small portion of their population, yet have a low positive rate, could be overwhelmed by cases down the road.

Testing shortages have led to tests generally being reserved for health care workers and the sickest patients, meaning that a lot of mildly symptomatic or asymptomatic people aren't being tested at all.

• We're also not yet doing surveillance testing on the scale needed.
• Some states — like New York or Massachusetts — are completing more tests than others after adjusting for population, but still have a higher positivity rate. That means that those states have a much larger caseload than others, and thus need to test more.

What we're watching: As states begin to lift social distancing measures, those who do so while their positive rate is still high will be particularly vulnerable to new outbreaks.

Whether in the workplace or the mall, people can expect that an opened-up world will involve more intrusive security measures and surveillance, Axios' Jennifer Kingson reports.

Why it matters: All the new coronavirus protocols that companies are considering for their workers and customers — from contact tracing and temperature-taking to heat mapping and "immunity passports" — have privacy and civil liberties implications.

Where it stands: While there's evidence that people are less concerned with privacy than before the pandemic hit — and more concerned with health — they still may not be ready for a world where their blood is tested for antibodies before boarding an airplane, as Dubai-based Emirates airlines has started doing.

Other options could have a far broader reach.

• Employers are entitled to mandate that workers get their temperature taken at the workplace, report any symptoms to their boss, and get a COVID-19 vaccine if one is developed, per WSJ.
• Apple and Google are collaborating on an app-based system for contact tracing that "uses Bluetooth to determine if users have recently been in close proximity to someone with the coronavirus," Axios' Ina Fried reports.

Where it's going: Companies are going to be collecting a lot more information about people — through contactless payment systems, which will be in growing use as people avoid face-to-face transactions, and through the various technologies in development that will track people's virus exposure.

• But the security of that information will be vulnerable to hacking or misuse, as well as public skepticism.

The "sharing economy" — as embodied by companies like Uber, Airbnb, and WeWork — is in critical condition, thanks to the coronavirus pandemic.

Why it matters: Basic assumptions about the evolution of human behavior in the digital age are melting under the pressure of COVID-19, requiring us to recalibrate how we envision the tech-enabled future, Axios' Scott Rosenberg reports.

The big picture: The sharing economy — an idealistic vision birthed and branded in the late 2000s, during the last economic crisis — held that Americans were moving beyond an ethos of acquiring and protecting stuff.

• Instead, we would willingly share use and enjoyment of space, vehicles and tools, saving money to buy memorable experiences and fulfilling leisure activities.

What's next: In some ways, the pandemic opens a door to the revival of the sharing economy's original, grassroots ideals of community cooperation and peer-to-peer trust.

• There's a lot of flour, sugar and yeast passing from neighbor to neighbor these days, even if we're just leaving it on one another's doorsteps.
• We may not rush back into shared spaces — but we've experienced a profound demonstration of interdependence.
