## Key points

- Mathematical modeling and non-pharmaceutical interventions are crucial in controlling the spread of infectious diseases, especially during the COVID-19 pandemic.
- Jorge P. Rodríguez, Alberto Aleta, and Yamir Moreno developed a high-resolution agent-based model to simulate the spread of COVID-19 in five Spanish cities.
- The model synthesized multiple data sources to capture the main interaction environments leading to potential contacts among populations.
- The researchers studied the effects of several non-pharmaceutical interventions on disease transmission in these cities.
- Their approach provided a first tool for simulating different intervention scenarios for decision-making.
- Digital cities can help characterize the impact of non-pharmaceutical interventions on COVID-19 spread by suppressing specific interventions in simulated scenarios.
- The study's results illustrate which measures were most effective at reducing transmission rates.
- Data-driven models have potential to inform policy decisions related to infectious disease control.
- Continued research into quantitative approaches that can account for population-specific factors is necessary when designing effective intervention strategies.

## Summary

The COVID-19 pandemic has highlighted the importance of mathematical modeling and non-pharmaceutical interventions in controlling the spread of infectious diseases. To address the lack of quantitative approaches to assess the impact of these interventions, which can vary depending on cultural, regional, and population-specific circumstances, Jorge P. Rodríguez, Alberto Aleta, and Yamir Moreno developed a high-resolution agent-based model to simulate the spread of COVID-19 in five Spanish cities. Their model synthesized multiple data sources to capture the main interaction environments leading to potential contacts among populations. The researchers then studied the effects of several non-pharmaceutical interventions on disease transmission in these cities. They found that their approach provided a first tool for simulating different intervention scenarios for decision-making. The study's results illustrate how digital cities can help characterize the impact of non-pharmaceutical interventions on COVID-19 spread. By suppressing specific interventions in simulated scenarios, they were able to derive insights into which measures were most effective at reducing transmission rates. Overall, this work highlights the potential for data-driven models to inform policy decisions related to infectious disease control. It also underscores the need for continued research into quantitative approaches that can account for population-specific factors when designing effective intervention strategies.
