The coronavirus test being provided daily to tens of thousands of residents in Los Angeles and other parts of California may be producing inaccurate results, according to guidance from federal officials that could raise questions about the accuracy of infection data shaping the pandemic response. The guidance from the Food and Drug Administration warns healthcare providers and patients that the test made by Curative, a year-old start-up founded in Silicon Valley that supplies the oral swab tests at L.A.’s 10 drive-through testing sites, carries a “risk of false results, particularly false negative results.” (Lau and Nelson, 1/7)

KHN: Do-It-Yourself Contact Tracing Is A ‘Last Resort’ In Communities Besieged By Covid

The contact tracers of Washtenaw County in Michigan have been deluged with work and, to cope, the overburdened health department has a new tactic: It is asking residents who test positive for covid-19 to do their own contact tracing. Washtenaw is a county of nearly 350,000 residents who live in and around the city of Ann Arbor, about 45 minutes from Detroit. Until mid-October, a county team of 15 contact tracers was managing the workload. But by Thanksgiving, more than 1,000 residents were testing positive for the coronavirus every week, and the tracers could not keep pace. (Dahlberg, 1/8)

For months during the pandemic, Bay Area professionals have been working from home, connecting over Zoom, and deciding they don’t like what they see. It’s not their colleagues they’re objecting to, but their own faces — double chins, brow furrows and hooded eyelids. And they’re doing something about it, in droves. “I’ve never seen so many people want to have facial surgery at the same time, and so urgently, in my 20 years in practice,” said Dr. Carolyn Chang, a San Francisco cosmetic plastic surgeon who specializes in faces and breasts.
