Fast, cheap tests could enable safer reopening

We integrate anonymized, geolocalized mobility data with census and demographic data to build a detailed model of transmission in Boston. We find that strict social distancing followed by testing, contact-tracing and quarantine could keep the disease within capacity of healthcare system while enabling the reopening of economic activities.
It remains unclear how real-world social networks could influence the effectiveness and efficiency of such approaches. To address this issue, we simulated control strategies for SARS-CoV-2 transmission in a real-world social network generated from high-resolution GPS data.
Smart Pooling: AI-powered COVID-19 testing
M Escobar et al, MEDRXIV<,August 5, 2020
We devised a quantitative measure to estimate genetic determinants of ACE2 and TMPRSS2 expression and applied this measure to >2500 individuals. Our data show significant variability in genetic determinants of expression among individuals and between populations, and indicate a predisposition for lower expression levels in African populations.
In this cohort study of 303 patients with SARS-CoV-2 infection isolated in a community treatment center in Korea, 110 (36.3%) were asymptomatic at the time of isolation and 21 (19.1%) developed symptoms during isolation. The threshold values of reverse transcription–polymerase chain reaction in asymptomatic patients were similar to those in symptomatic patients.
