Why Apple and Google’s Virus Alert Apps Had Limited

Sarah Cavey, a real estate agent in Denver, was thrilled last fall when Colorado introduced an app to warn people of possible coronavirus exposures.

Based on software from Apple and Google, the state’s smartphone app uses Bluetooth signals to detect users who come into close contact. If a user later tests positive, the person can anonymously notify other app users whom the person may have crossed paths with in restaurants, on trains or elsewhere.

Ms. Cavey immediately downloaded the app. But after testing positive for the virus in February, she was unable to get the special verification code she needed from the state to warn others, she said, even after calling Colorado’s health department three times.

NDAC was formed by experienced dialysis professionals with a long history of career success in the regulatory, clinical, and operational functions of dialysis. The daily focus of our experienced survey team is to ensure that patients in every dialysis facility are treated in a safe environment with quality care and that our dialysis provider customers and their staffs experience an accreditation survey that exceeds their service expectations.

The surveyor team was very professional from start to finish, extremely knowledgeable and delighted with the state of the facility. During the survey, the surveyor team explained to the staff what to expect during each step of the process. Because of this open communication, the staff felt comfortable with the surveyor team during their interviews with them. We will use NDAC again and recommend them highly to other dialysis providers.

The horror lurking in the darkness is a throng of thousands of mice swarming above, around and inside a storage bunker of wheat at the Fragar family’s farm seven hours west of Sydney, Australia. After a long and painful drought, the mice are ravaging the family’s first good harvest in years and endangering the next one, putting their business on the brink of ruin.

Their farm is just one of thousands along the country’s eastern grain belt that are contending with what local residents call the worst mouse plague in living memory, with far-reaching consequences both in the fields and in rural communities.

It’s like “watching the mice eat away at your future,” said Kathy Fragar, 51.

Soaring assets and stocks in the past year have in some cases handed midlevel workers huge windfalls.

Those who have benefited from the market surge typically fall into one of three categories, said Sahil Vakil, founder of personal-finance tech company MYRA: They were given company shares as compensation and those same shares recently boomed; they caught last year’s retail investing frenzy and rode the market to new highs; or they invested early on in cryptocurrency, to great success.

Last summer, millions of Americans took to the streets after the killing of George Floyd at the hands of the Minneapolis police, taking part in what would become the largest protest movement in U.S. history. Many participated in marches and demonstrations for the first time in their lives. From eight first-time protesters, here are reflections on what they did last summer, how this has affected them in the year since and what lies ahead. Their interviews have been edited and condensed.
