"Because there hasn't been a lot of communication yet about what an 'official' contact-tracing notice would look like, users have few ways to ascertain whether what they received is a scam," says Jake Williams, a security consultant and founder of the firm Rendition Infosec.
As people start to slide back into close contact with one another, the nation’s top health officials are worried that the US still doesn’t have systems in place to effectively test, track, and halt the spread of the deadly respiratory disease.
“It could be groups with underlying health conditions, or people who, because of the kind of work they’re doing, can’t avoid contact—like health care workers, police officers, grocery store workers,” Handel says.The vaccine against seasonal influenza, for example, isn’t as effective in older people.

The pandemic has fueled debate about contact-tracing apps, but researchers say that it is possible to design encryption schemes for such services in a way that would successfully protect user privacy.
On Friday, the two companies announced a rare joint project to create the groundwork for Bluetooth-based contact-tracing apps that can work across both iOS and Android phones.
But the next iteration of the app will build in the ability to sort all the recorded locations of any users diagnosed as Covid-19 positive into "tiles" of a few square miles, and then cryptographically "hash" each piece of location and time data.
“This is not black and white,” says Ben Lopman, an infectious disease epidemiologist at Emory University’s Rollins School of Public Health.From a mathematical perspective, determining how big a crowd is safe depends on a couple of key questions: How many people in a given area are infected with the disease?
In the first months after moving to New York City in 2008, Israeli-born photographer Natan Dvir liked to time how long he could stare at fellow subway passengers before one of them made eye contact.
