What is “close contact” in the era of the delta variant?

Hello, Bay Area. It’s Wednesday August 25th and the scene in Lake Tahoe is smoky and grim. Here’s what you need to know to start your day.

The rise of the highly transmissible delta variant has forced a quick pivot on some key pandemic public health recommendations, but experts say there is still one that could use a new review: the definition of “close contact” with a patient. infected person.

This standard dictates when a person exposed to the coronavirus should get tested or self-isolate, and for most of the COVID-19 pandemic, the directive has been “6 feet for 15 minutes.” But experts say that since Delta turned the situation around, new understanding is needed as people make choices about their behaviors and risks.

Lost outdoor paradise

Smoke filled the sky over Emerald Bay of Lake Tahoe on Tuesday.

With Caldor’s Growing Fire encroaching on the Lake Tahoe Basin on Tuesday, the area has gone from an outdoor paradise to a place to endure. The sky, usually as blue as the lake, turned yellowish gray, and the normally pine-scented air stank like a soggy ashtray.

Campgrounds and beaches have been closed, boats have been banned from accessing the lake, and even the iconic gondola that carries visitors from the Stateline area to the Heavenly Resort has been closed. It wasn’t the end of summer at the lake that residents and visitors are used to.

“We’ve never seen so much smoke here, ever,” said Joe Stella, manager of Powder House ski, snowboard and bike rental store.

In the backroom of APROE, a design and engineering company in San Francisco’s Design District, a top-secret project takes shape: prototypes for the city of San Francisco’s new trash can, which has been discussed at length. . They will cost $ 12,000 each – the low end of the Department of Public Works’ initial estimates of up to $ 20,000.

When the cans are finally produced in large quantities, they will cost between $ 2,000 and $ 3,000, still expensive but less expensive than the competition. But as columnist Heather Knight writes, the most distressing figure is the time it takes for the notoriously slow City Hall to replace the 3,000 trash cans that have already passed their lifespan.

Enter APROE’s design studio with Knight and learn about his potential, still unsigned, deal to create 15 cans – five of each prototype – to place in the city in November for testing.
