Obese people could spread flu for longer

According to research carried out at the University of Michigan, adults tended to carry the flu virus for longer if they were obese, suggesting that flu jabs should also be targeted towards people who are obese. Obese adults were shown to have the Influenza-A virus for 42% longer than adults who were not obese. Previous research has suggested that obesity leads to a higher risk of flu complications and more severe infections. 

Dr. Aubree Gordon, assistant professor of epidemiology at the University of Michigan School of Public Health said: "this is the first real evidence that obesity might impact more than disease severity. It might directly impact transmission as well."
