ABSTRACT We analyze risk factors correlated with the initial transmission growth rate of the recent COVID-19 pandemic in different countries. The number of cases follows in its early stages an almost exponential expansion; we chose as a starting point in each country the first day with 30 cases and we fitted for 12 days, capturing thus the early exponential growth. We looked then for linear correlations of the exponents with other variables, for a sample of 126 countries. We find a positive…

Early Spread of COVID-19 in the Air-Polluted Regions of Eight Severely Affected Countries
COVID-19 escalated into a pandemic posing several humanitarian as well as scientific challenges. We here investigated the geographical character of the early spread of the infection and correlated it
Investigation of superspreading COVID-19 outbreak events in meat and poultry processing plants in Germany: A cross-sectional study
TLDR
It is indicated that climate conditions and low outdoor air flow are factors that can promote the spread of SARS-CoV-2 aerosols and a possible requirement for pandemic mitigation strategies in industrial workplace settings is to increase the ventilation rate.
The Effects of Air Pollution on COVID-19 Infection and Mortality—A Review on Recent Evidence
TLDR
The findings of most studies reviewed here demonstrate that both short-term and long-term exposure to air pollution especially PM2.5 and nitrogen dioxide (NO2) may contribute significantly to higher rates of COVID-19 infections and mortalities with a lesser extent also PM10.
PM2.5 as a major predictor of COVID-19 basic reproduction number in the USA
The impact of vaccination on the spread patterns of the COVID epidemic
TLDR
A modified model of the coronavirus epidemic under conditions of mass vaccination was developed and it was particularly shown that the cancellation of the lockdown together with the start of vaccination did not reduce the maximum number of new infections.
COVID-19 and Vitamin D– a Systematic Review
TLDR
Vitamin D supplementation might play an important role in protecting from acute respiratory infections like the SARS CoV2, and in high-risk individuals with COVID 19 from progressing to critical clinical condition and reducing mortality.
A Basic Review of the Preliminary Evidence That COVID-19 Risk and Severity Is Increased in Vitamin D Deficiency
TLDR
The literature review found that prophylactically correcting possible vitamin D deficiency during the COVID-19 pandemic is extremely safe and recommended 2,000 IU of vitamin D daily for all populations with limited ability to manufacture vitamin D from the sun.
Geospatial Analysis of Individual and Community-Level Socioeconomic Factors Impacting SARS-CoV-2 Prevalence and Outcomes
TLDR
SARS-CoV-2 infection and hospitalization rates, but not death rates among those hospitalized, are related to census tract-level socioeconomic characteristics including lower educational attainment and higher household crowding and occupancy, butNot neighborhood measures of race, independent of individual factors.

Temperature Decreases Spread Parameters of the New Covid-19 Case Dynamics
TLDR
Results indicate that high temperatures diminish initial contagion rates, but seasonal temperature effects at later stages of the epidemy remain questionable, and confinement policies and other eviction rules should account for climatological heterogeneities.
A novel methodology for epidemic risk assessment of COVID-19 outbreak
TLDR
A novel data-driven framework for assessing the a-priori epidemic risk of a geographical area and for identifying high-risk areas within a country is proposed and can be extended and tested on other epidemic data, such as those on seasonal flu, and applied to other countries.
A Novel Methodology for Epidemic Risk Assessment: the case of COVID-19 outbreak in Italy
TLDR
A novel data-driven framework for assessing the a-priori epidemic risk of a geographical area and for identifying high-risk areas within a country is proposed and a policy model connected with the methodology is presented, which helps policy-makers to take informed decisions.
High Temperature and High Humidity Reduce the Transmission of COVID-19
With the ongoing global pandemic of COVID-19, a question is whether the coming summer in the northern hemisphere will reduce the transmission intensity of COVID-19 with increased humidity and
Exponential phase of covid19 expansion is not driven by climate at global scale
TLDR
The results indicate that the current claims that the growth rate of COVID-19 may be lower in tropical countries should be taken very carefully, at risk to disturb well-established and effective policy of social isolation that may help to avoid higher mortality rates due to collapse of national health systems.
Higher virulence of COVID-19 in the air-polluted regions of eight severely affected countries
TLDR
In Italy, the correspondence between the Po valley pollution and SARS-CoV-2 infections and induced mortality was the starkest, originating right in the most polluted European area, suggesting the detrimental impact climate change will have on the trajectory of future respiratory epidemics.
Differential COVID-19-attributable mortality and BCG vaccine use in countries
TLDR
Assessment of the association of BCG use and COVID-19-attributable mortality per 1 million population after adjusting for confounders provides intriguing observations that urgently warrant mobilization of resources for prospective randomized interventional studies and institution of systematic disease surveillance, particularly in LMICs.
COVID-19 attack rate increases with city size
TLDR
It is revealed that COVID-19 is spreading faster on average in larger cities with the additional implication that, in an uncontrolled outbreak, larger fractions of the population are expected to become infected in more populous urban areas.
Impact of temperature and relative humidity on the transmission of COVID-19: a modelling study in China and the United States
TLDR
Higher temperature and higher relative humidity potentially suppress the transmission of COVID-19 across communities and the potential impact of temperature/relative humidity on the effective reproductive number alone is not strong enough to stop the pandemic.
