Many pathogens can cause influenza, according to the London-based research team, which has made it difficult to assess how often people come down with it. In the study, the team analyzed blood samples from volunteers in Southern China and counted antibodies that came from an array of nine flu strains that had passed through the area between 1968 and 2009. Data led them to conclude that while children come down with the flu every other year, on average, adults over 30 get it twice per decade. Flu symptoms are sometimes caused by common cold viruses including rhinovirus and coronavirus, says author Dr. Adam Kucharski of Imperial College London, and some never know they caught the flu because they show no symptoms. “In childhood and adolescence, it’s much more common, possibly because we mix more with other people,” says Dr. Kucharski. “The exact frequency of infection will vary depending on background levels of flu and vaccination.” To account for changes in human immunity to flu that occur over time as we are exposed to different strains of it, the research team developed a mathematical model. The model supports prior research suggesting that our immune Read More …
