Dear All,
Some of the future seminars may be hybrid face-to-face/Zoom events (when the speaker is physically at IFISC). This is to make scientific exchange easier. The seminar today will be of this type.
If you’d like to attend in person, then please come to the seminar room just before 14:30. There is a limit on the number of people who can be in the room, and a first-come-first-served principle will apply. I cannot be there today, but Raúl has kindly agreed to manage the session. There will not be coffee or biscuits. Please do not bring your own coffee into the seminar room, you must wear a mask at all times.
If you can’t come to the seminar room (or come too late), then you can follow the seminar & ask questions via Zoom.

IFISC Seminar on Wednesday Oct 06, 2021 at 14:30
Place: IFISC Seminar Room
Series: IFISC Seminar Javier Aguilar Sanchez, IFISC
Abstract:
The SARS-CoV-2 pandemic evidences that promptly detecting which areas and
regions are most susceptible to reinfections is critical to implement adequate containment
policies. Mobility has always been key to viral spreading, but the relatively slow pace of vaccination in the majority of countries,
together with the appearance of new aggressive variants, have forced mitigation measures to rely
primarily on non-pharmaceutical interventions This puts urban centers in
the focus of epidemic surveillance and intervention. Here we show that the organization of
urban flows has a tremendous impact on disease spreading and on mitigation strategies. By studying anonymous and aggregated intra-urban flows in a variety ofcities in the US and other countries, and a combination of empirical analysis and
numerical methods, we demonstrate that the response of cities to epidemic spreading can be
classified into two major types. Centralized cities are
particularly vulnerable to the rapid spread of epidemics. Nevertheless, mobility restrictions in
such types of cities are very effective in mitigating the spread of a virus. Conversely, in
sprawled cities that present many centers of activity, the spread of an epidemic is much
slower, but the response to mobility restrictions is much weaker and less effective.
