Cities’ population and transportation patterns affect how flu epidemics play out

MISMS researchers published a study in Science showing that winter flu epidemics in smaller cities tend to have higher flu epidemic intensity than in larger cities highly connected by extensive transportation systems, which have longer, more consistent flu seasons.

The study has important implications for understanding how cities of different sizes should prepare for annual flu epidemics. Smaller cities with more spiked epidemics may need to increase their surge capacity, while larger cities may need to prepare for epidemics that last for many months.
