Effects of Mobility and Multi-Seeding on the Propagation of the COVID-19 in Spain

Topic:

  • Mazzoli et al. found that between-region mobility explained the high heterogeneity in incidence between otherwise similar geographic regions of Spain that implemented uniform mobility control measures.  
  • Their findings suggest that “multi-seeding,” which occurs when multiple infected individuals arrive in a susceptible population, likely played an important role in the spreading of SARS-CoV-2 from the initial outbreak in Madrid to other regions of Spain.
