The drivers behind regional differences of SARS-CoV-2 spread on finer spatio-temporal scales are yet to be fully understood. Here we develop a data-driven modelling approach based on an age-structured compartmental model that compares 116 Austrian regions to a suitably chosen control set of regions to explain variations in local transmission rates through a combination of meteorological factors, non-pharmaceutical interventions and mobility. We find that more than 60% of the observed regional…

Small coverage effect in epidemic network models shows that masks can become more effective with less people wearing them

The results contradict the popular belief that masking becomes ineffectual as more people drop their masks and might have far-reaching implications for the protection of vulnerable population groups under resurgent infection waves.

Assessing SARS-CoV-2 Prevalence in Austria with Sample Surveys in 2020 - A Report

A valid assessment of the population acutely infected by SARS-CoV-2 in Austria at three distinct points in time: April, May and November 2020 is presented.

A network-based explanation of why most COVID-19 infection curves are linear

It is shown that for any given transmission rate there exists a critical number of social contacts, Dc, below which linear growth and low infection prevalence must occur, above which traditional epidemiological dynamics take place, e.g., as in susceptible–infected–recovered (SIR) models.

Prevalence of SARS-CoV-2 infection in patients presenting for intravitreal injection

The study provides an estimate for the prevalence of SARS-CoV‑2 infection in asymptomatic patients presenting for IVI and suggests that this patient group may be used as a baseline for future research to support risk assessment and infection prevention strategies.

Temperature and population density influence SARS-CoV-2 transmission in the absence of nonpharmaceutical interventions

It is shown that summer weather cannot be considered a substitute for mitigation policies, but that lower autumn and winter temperatures may lead to an increase in transmission intensity in the absence of policy interventions or behavioral changes, and that lower temperatures and higher population densities are correlated with increased SARS-CoV-2 transmission.

Revealing fine-scale spatiotemporal differences in SARS-CoV-2 introduction and spread

Analysis of 247 full-genome SARS-CoV-2 sequences from two nearby communities in Wisconsin, USA finds surprisingly distinct patterns of viral spread, which suggest patterns of Sars-Cov-2 transmission may vary substantially even in nearby communities.

The impact of non-pharmaceutical interventions on SARS-CoV-2 transmission across 130 countries and territories

The effectiveness of school closure and internal movement restrictions appears robust across different model specifications, with some evidence that other NPIs may also be effective under particular conditions, as well as temporal clustering between many of the NPIs.

Increasing Temperature and Relative Humidity Accelerates Inactivation of SARS-CoV-2 on Surfaces

The effects of relative humidity, temperature, and droplet size on the stability of SARS-CoV-2 in a simulated clinically relevant matrix dried on nonporous surfaces suggest that a potential for fomite transmission may persist for hours to days in indoor environments and have implications for assessment of the risk posed by surface contamination in indoors environments.
