Researchers from the University of Michigan analysed 1,800 adults and children in 320 Nicaraguan households from 2015 to 2017, observing the effect of obesity on the duration of viral shedding.
It found that obese adults with flu symptoms shed the virus for 42% longer than adults who weren’t obese.
