The Covid-19 pandemic is the most significant global crisis since the Second World
War. Exceeding the size and range of the repercussions of a World War, it has affected
all the Countries of our planet.
The health consequences of the pandemic are devastating. To date the number of Covid-19
deaths exceeds 50,000 and is unfortunately destined to exponentially grow in the coming
weeks.
Furthermore, the pandemic has led to unprecedented social consequences and upheaval.
It is estimated that more than 4 billion people (a half of the entire mankind) are
today affected by drastic restrictions in their movements and social relationships.
The pandemic has also triggered a global economic crisis, quite unlike those of the
previous decades, whose shock will be felt for years to come. Already due to the pandemic
the vast majority of our habits, trade, social and economic relations, methods, forms
of work, and political organizations have already fundamentally changed.
It is surprising that our governments, our social policies and our health systems
were globally unprepared to manage such a situation, even though we all knew an impending
pandemic was simply a matter of time – a time which has now arrived.
Such abject lack of preparedness, from day one of the outbreak, is the main cause
of the delays and inadequacies of our decisions and actions, taken at the local, national
and international levels, to contain the virus.
The large-scale spreading of viral or bacterial pathogens are to be considered among
the main threats to humanity and society.
This is just one reason why it is urgent that we act today.
Here is a pressing and immediate need for the scientific community to come together
and provide novel and better methods, strategies, forecasting techniques and models,
to understand and mitigate the effects of this and future pandemics.
Such advances are needed in both the short and longer term to inform effective and
objective policies and strategies to be adopted.
As editors of Chaos, Solitons and Fractals, a fundamentally interdisciplinary journal,
we are deeply convinced that addressing epidemic spreading requires a broader scientific
debate and a more profound interplay between the disparate scientific communities
that have tried to tackle the problem so far.
Indeed, we have identified at least three scientific communities that may auspiciously
cooperate in the effort to deal more successfully with circumstances like the current
pandemic – (1) the community of applied mathematicians, virologists and epidemiologists,
who for years have been developing ever more sophisticated diffusion models which
are increasingly attentive to the specific properties of a given pathogen; (2) the
community of complex systems scientists who have approached the study of the spread
of infections by means of compartmental models in networked populations, and used
the arsenal of methods and principles borrowed from statistical mechanics and nonlinear
dynamics; and (3) the community of scientists who are advancing science through the
incorporation of artificial intelligence and deep learning, to produce successful
and productive predictive models driven by vast amounts of data.
Emboldened by our convictions and spirit, we propose to launch an open Focus Issue
of Chaos, Solitons and Fractals dedicated to all aspects of epidemic spreading, with
the aim of providing a unique (but desperately needed) forum where ideas, studies,
concepts, methods arising from the applied mathematics, the virology, the epidemiology,
the nonlinear science and the artificial intelligence communities can be shared and
integrated, to enrich our global efforts for understanding and mitigating the effects
of the current pandemic while enabling us to avoid the worst effects of future pandemics.
We are strongly aware that such an initiative requires (in order to be attractive
and inclusive) editorial procedures which have to be different from those adopted
with regular submissions to the journal. We need to be nimble and timely!
To ensure the maximal rapidity in the diffusion and dissemination results and ideas
we propose to commit ourselves, as Guest Editors, to rapidly process, review and come
to a decision on all submissions. We propose to reach the quickest decisions by the
means of utilizing, as Referees, experts from the journal's editorial board.
Moreover, in order to have all information instantly available for consultation, we
decided to adopt a novel publication model: articles submitted to this Focus Issue
will be published in regular issues of the Journal as soon as accepted, while the
entire Focus Issue content will be brought together in an online special issue, easily
accessible and navigable on ScienceDirect.
The call for Manuscripts will close on September 31st, 2020, with a final online publication
of the entire Focus Issue proposed for November, 2020.
We hope you are able to enthusiastically embrace and approve our proposed Focus Issue
so we can get started immediately!
