| US Covid-19 deaths climb, the CDC considers changing quarantine recommendations, and AstraZeneca's vaccine results may be shaky. Here's what you should know: Headlines US reports its highest one-day coronavirus death toll since early May The US reported more than 2,100 coronavirus deaths on Tuesday, the highest one-day death toll since early May. This follows the predictions of many officials, who said death rates would trail the recent surge in cases and hospitalizations by a few weeks. Tuesday also set a record for number of people in the US hospitalized. These numbers are likely to rise further in the coming weeks as many Americans travel to celebrate Thanksgiving, against the guidelines of the CDC. CDC contemplates reducing the recommended quarantine period for those exposed to coronavirus There are reports that the CDC may soon change its recommendations for isolation following contact with someone who has Covid-19. Right now, the agency calls for people to isolate for two full weeks. That may soon be reduced to seven to 10 days for those who receive a negative test at the end of that time. The hope is that reducing the recommended quarantine time to the period when people are most likely to become contagious will actually boost compliance and ultimately decrease spread. AstraZeneca's vaccine may be viable—but this week's results aren't enough On Monday, Oxford and AstraZeneca released what seemed like positive results from clinical trials for its coronavirus vaccine. But these findings are markedly different from those released by Pfizer and Moderna earlier this month. The results Oxford and AstraZeneca presented came from two separate studies with different dosing schemes rather than a single, large Phase III trial. And only the results of certain subgroups were included in the findings. The vaccine may be viable, but more data is necessary to prove it. Daily Distraction Holiday season is upon us.

One Question Who should get a coronavirus vaccine first? It's likely that health care workers will be the first to get a vaccine when it's available, and they probably should. Physicists who work on network theory, though, have another way of thinking about vaccine distribution: To slow spread quickly, you need to find the social butterflies, the people at the center of their communities. If you asked everyone to name a single acquaintance, it's likely many of them will name the same person, the ones who socialize the most and thus are most likely to be superspreaders. And if you vaccinate them first, that could halt the spread of coronavirus in record time.
