Here we show that the organization of<br /> urban flows has a tremendous impact on disease spreading and on&nbsp;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<br /> numerical methods, we demonstrate that the response of cities to epidemic spreading can be<br /> classified into two major types.&nbsp;Centralized cities&nbsp;are<br /> particularly vulnerable to the rapid spread of epidemics. Nevertheless, mobility restrictions in<br /> such types of cities are very effective in mitigating the spread of a virus. Conversely, in<br /> sprawled cities that present many centers of activity, the spread of an epidemic is much<br /> slower, but the response to mobility restrictions is much weaker and less effective.<br /> <br /> <a href="https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09">https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09</a></p>; Url event:https://ifisc.uib-csic.es/en/events/seminars/impact-of-urban-structure-on-in...
