New paper: our method HIV-phyloTSI estimates time-since-infection for HIV using deep viral sequence data. Estimating continuous TSI, not just recent / not-recent, gives incidence over time, allowing evaluation of the impact of interventions. 1/3 bmcbioinformatics.biomedcentral.com/articles/10....

👋 Hello World! Some of our papers this year ICYMI Ferretti & Wymant et al, Nature: using 7 million digitally recorded COVID exposures, we found app-based contact tracing successfully measured the actual risk of transmission and we decomposed contributors to risk 045.medsci.ox.ac.uk/risk_measure...
Image shows how the probability of reported infection with SARS-CoV-2 among people notified by the NHS COVID-19 App increases with the risk score calculated by the app.
