A new study says that this winter’s flu season may last longer in large cities, while smaller cities will experience a shorter but more explosive bout with the virus.
That news follows a CDC revelation that an estimated 80,000 Americans died of flu and its complications last winter, which would make that season the highest death toll the country has seen from the flu in at least four decades.
The study, published in the October issue of the journal Science, presents evidence that flu incidence tends to fluctuate depending on environmental moisture levels, population density, and activity levels of the general population. By that logic, it would seem reasonable that cities near the humid coastlines or with larger populations that spend more time together inside during flu season will be subject to a longer, “more diffuse” infection season.
