The pandemic of coronavirus disease 2019 (COVID-19) is rapidly spreading all over the world, generating a high number of total deaths. One of the current questions is: how atmospheric factor of wind, in the presence of high levels of air pollution, affects the diffusion of COVID-19? This study...

This study analyses data on COVID-19 cases alongside environmental, demographic and geographic data. This study focuses on Italy that has had rapid diffusion of COVID-19 in society during the first wave of COVID-19 pandemic in 2020. Results show that cities with little wind, high humidity and...

One of the fundamental problems in the COVID-19 pandemic crisis is the critical decision of introducing or not wide social restrictions, such as national lockdown, with the expectation of reducing the final impact of the novel coronavirus in society. This study analyzes, in an international...

One of the fundamental problems in the crisis management of COVID-19 pandemic is to know the impact on public health of the second wave of the COVID-19 compared to first wave for designing effective policy responses to cope with this on-going socioeconomic and health crisis in society. The...

This paper suggests a metrics that measures the environmental risk of exposure of cities to future waves of COVID-19 and epidemics of similar vital agents. The proposed index combines environmental, socioeconomic and health risk factors of cities to assess their vulnerability to the diffusion of...

This paper endeavors to explain how wind speed can affect the diffusion of COVID-19. The statistical analysis, based on data from Italy, suggests that high wind speed can reduce air pollution commingled with viral agents and as a consequence reduce infected individuals of COVID-19; moreover,...
