Meteorological factors and Covid-19 incidence in 310 regions across the world

This study analyzed l data from 311 regions across 116 countries with reported cases of COVID-19 by March 12, 2020, and found that temperature, humidity, and wind speed were inversely associated with the incidence rate of Covid-19. This means that it is likely that as temperature, humidity and wind speed increase the spread of COVID-19 decreases.

Mobility traces and spreading of COVID-19

The authors have built human mobility models, for which they are experts, and attach a virus infection dynamics to it. This results in a virus spreading dynamics model. The preliminary model shows that complete lockdown works. About 10 days after lockdown, the infection dynamics die down in the model. Infections in public transport play an important role, they say. The simulations say that complete removal of infections at child care, primary schools, workplaces and during leisure activities will not be enough to sufficiently slow down the infection dynamics.

A mathematical model of COVID-19 transmission between frontliners and the general public | medRxiv

This study formulates a conceptual mathematical model on the transmission dynamics of COVID-19 between the frontliners (e.g. healthcare workers, customer service and retail personnel, food service crews) and the general public. The take-home message of this preliminary model is that everyone in the community, whether a frontliner or not, should be protected or should implement preventive measures to avoid being infected.
