Containing Covid-19 outbreaks with spatiallytargeted short-term lockdowns and mass-testing
J Alsing et al, MEDRXIV, May 9, 2020

The network model is based on commuter data, a catchment area model for schools, and a phenomenological model for mobility and interactions outside of work, school, and the home. We show that for outbreak scenarios targeted lockdowns or mass-testing interventions at the level of individual communities can be effective at containing outbreaks.

Quantifying SARS-CoV-2 transmission suggests epidemic control with digital contact tracing
L Ferretti et al, Science, May 8, 2020

Given the virus infectiousness and the high proportion of transmissions from presymptomatic individuals, controlling the epidemic by manual contact tracing is infeasible. A contact-tracing app with a memory of proximity contacts and notifies them would be sufficient to stop the epidemic, in particular when combined with other measures such as physical distancing

NIH-supported research survey to examine impact of COVID-19 on rare diseases community
NIH, May 7, 2020

For the millions of people living with a rare disease, the novel coronavirus disease COVID-19 presents challenges, from potential reduced access to needed medical care to possible heightened anxiety and stress. A new online survey aims to find out how the COVID-19 pandemic is impacting individuals with rare diseases, their families and their caregivers.

Modeling shield immunity to reduce COVID-19 epidemic spread
JS Weitz et al, Nature Medicine, May 7, 2020

We have developed and analyzed an epidemiological intervention model that leverages serological tests6,7 to identify and deploy recovered individuals8 as focal points for sustaining safer interactions via interaction substitution, developing what we term ‘shield immunity’ at the population scale.
