The Latest: The case for the rapid Covid-19 test
Everyday life is now dominated by near-constant risk assessments. Whether it’s navigating the weekly grocery run or deciding if it’s safe to send children to school, the endless decision-making can take its toll on the brain. So how do you approach pandemic choices? Two infectious disease epidemiologists put together this very thorough five-step decision framework that’s meant to empower people to make informed choices about daily life in the same way pandemic experts do.
People are also finding their own ways to deal with the uncertainty of modern life, including a turn to spirituality. This feature looks at how spirituality as wellness is growing in the pandemic, from an increase in daily prayer to a doubling down on practices like astrology and tarot.

A pandemic perspective:
Here’s what we’re talking about this week:
Rapid but less effective tests might be the answer.
The backlogs for Covid-19 tests are bananas. Some people, including my colleagues, are waiting weeks for results. But there’s a dream scenario in which you could test yourself for Covid-19 and get an answer right away. Some health experts are pushing for the U.S. to embrace antigen tests, which are cheaper and faster-acting than the gold standard test currently being used. However, the Food and Drug Administration requires Covid-19 tests to detect at least 80% of positive cases, and these rapid tests are closer to 50%. While that doesn’t seem great, that difference in accuracy is really only at the very beginning or very end of the disease, when people aren’t really infectious. “The tests are much more precise when people have millions of viral copies in their nose and throat, which is also when they’re most infectious, even without symptoms,” reporter Dana Smith writes.

Who is waiting for tests?
A recent analysis of testing sites found that white neighborhoods have more access to testing sites and that testing sites in communities of color in many U.S. cities face higher demand, longer wait times, and are understaffed. This is one issue contributing to a larger problem of not getting testing access to people most at risk. “When access to testing is divorced from risk, the numbers lose their meaning and can mask failure,” Natalie Dean, PhD, assistant professor of biostatistics at the University of Florida, recently shared on Twitter. “This is why disaggregating even further (race, neighborhood, occupation, symptom status, etc.) is needed.” Read more about the issue here.
There’s a case for slowing down vaccine trials.
A vaccine for Covid-19 is a highly anticipated breakthrough for this pandemic. I am dreaming about the day I can get one; it can’t come soon enough. But many scientists worry that the rush to get a vaccine to market could lose public trust if the time isn’t taken to confirm the vaccine is safe and effective. Over 400 vaccine experts signed a letter this week to the head of the FDA urging caution regarding the White House’s “Warp Speed” Covid-19 vaccine race, writing that “an effective vaccine will only be truly useful if a large proportion of the public is willing to take it. More than 60% of U.S. voters prefer that a Covid-19 vaccine be thoroughly evaluated before it is made available, even if doing so delays its rollout.” Read more about the letter here.
Is your brain fried, or is it experiencing allostatic load?
Yesterday, Dana Smith and I chatted about how the brain processes the stress of navigating the pandemic. According to Dana, the brain can become exhausted from constant anxiety. “With stress, the brain evolved to deal with acute stress — the tiger, the snake, whatever. That triggers hormones to cue your fight-or-flight response so you can deal with the threat immediately,” she says. “But with chronic stress, the threat doesn’t resolve, and those hormones don’t drop. That can lead to something called allostatic load, where essentially your brain just gets burned out by remaining in this amped-up state, and that can take a real toll and cause physical changes in your brain and body.” I think I’m experiencing allostatic load, and I bet you are too.
