WHY are some people better able to fight off the flu than others? Part of the answer, according to a new study, is related to the first flu strain we encounter in childhood.
Scientists from UCLA and the University of Arizona have found that people’s ability to fight off the flu virus is determined not only by the subtypes of flu they have had throughout their lives, but also by the sequence in which they are been infected by the viruses.
Their study is published in the open-access journal PLoS Pathogens . The research offers an explanation for why some people fare much worse than others when infected with the same strain of the flu virus, and the findings could help inform strategies for minimising the effects of the seasonal flu.
In addition, UCLA scientists, including Professor James Lloyd-Smith, who also was a senior author of the PLoS Pathogens research, recently completed a study that analyses travel-related screening for the new novel coronavirus COVID-19.
