      Here's a modeling paper that I haven't seen discussed as often as I would have liked. (Disclosure: my co-author Natalie Dean is a co-author of that paper.) http://www.cidid.org/publications-1/2020/5/5/modeling-the-impact-of-social-distancing-testing-contact-tracing-and-household-quarantine-on-second-wave-scenarios-of-the-covid-19-epidemic …pic.twitter.com/xFOHSihzyu

      In short, the authors develop a stochastic SEIR model with multiple network layers with contact structure parameterized by cell phone data and census data. They use this framework to evaluate plans for lifting current stay-at-home orders and nonessential business closures.pic.twitter.com/NZ0TxoMhIl

      They find that with a staggered reopening, isolation of symptomatic cases is insufficient to prevent a large second wave that would overrun hospital capacity. Adding a fairly modest level of contact tracing and family-scale isolation brings the second wave under control.pic.twitter.com/Us3De6fPgG

      Tracing is far from absolute; they assume that 50% of symptomatic infections are identified and 40% of those patients' contacts are identified. This turns out to make enough difference to keep the second wave down, though not to quickly eradicate disease.

      Both the methods and results are broadly consistent with our own work in progress, using @RS_McGee's SEIRS+ framework https://github.com/ryansmcgee/seirsplus … (though their way of building the contact network from phone data is more sophisticated).

      Throughout, the authors assume relatively undemanding levels of testing. To me the paper suggests that contact tracing is a viable and—at least in the absence of truly massive-scale testing—probably necessary component of plans to reopen the economy prior to an effective vaccine.

      Replying to @CT_Bergstrom

      2/2 OTOH people won't just go back to normal life if orders lifted, which reduces spread. Have you seen any studies on contact tracing pre-emptive quarantine compliance in USA? I'd expect it to be pretty low, ie mirror the 20% scenario perhaps? @DanielleFong @endCOVID19
