Type I, II, and III Interferon Signatures Correspond to COVID-19 Disease Severity

In an analysis of plasma levels of interferons (IFNs) and cytokines among patients with SARS-CoV-2 infection and varying disease severity (n=67), type I IFN responses appeared to be transient among those with mild disease but prolonged among those admitted to the ICU. Plasma levels of type II IFNs were comparable among patients overall and induced…

Emergence of an Early SARS-CoV-2 Epidemic in the United States

[Pre-print, not peer-reviewed] Genome sequencing combined with epidemiological and mobility data suggest show that SARS-COV-2 was likely introduced in Louisiana from a single source via domestic travel and was being locally spread prior to the Mardi Gras celebrations in February 2020. However, further evidence suggests that Mardi Gras was likely a superspreading event, based on…

Bidirectional Contact Tracing Could Dramatically Improve COVID-19 Control

A modeling study found that bi-directional contact tracing could double the reduction in effective reproductive number (Reff) compared to conventional forward-tracing alone. Bi-directional contact tracing identifies potential infectors of known cases, which could lead to identification of additional cases arising from the potential infectors. The authors also suggest expanding the tracing window from 2-6 days…
