SARS-CoV-2 infectivity by viral load, S gene variants and demographic factors and the utility of lateral flow devices to prevent transmission
Background: How SARS-CoV-2 infectivity varies with viral load is incompletely understood. Whether rapid point-of-care antigen lateral flow devices (LFDs) detect most potential transmission sources...

Updated pre-print on >2.4 million COVID contacts in England: transmission increases with higher viral loads. B.1.1.7 increases transmission by ~55%. Lowest risk of transmission from children. Lateral flow devices can detect up to 89.5% of infectious COVID. medrxiv.org/content/10.110… pic.twitter.com/oCgJH1iX11

For the B.1.1.7 variant (UK), a very large study showed 55% increased transmission, higher viral loads, and notably excellent detection (up to 89.5%) by rapid antigen tests medrxiv.org/content/10.110… by @drdavideyre and colleagues pic.twitter.com/huu6ajAcLS
