Why does the flu affect different people differently? Why do some
people infected with the influenza virus have symptoms resembling an
ordinary cold, while other people infected with the same virus may get
very sick or even die? Writing in the Journal of Leukocyte Biology, a
group of researchers say they now have a better understanding of some
of the factors involved in the severity of influenza infections. In an
infected person, they say, the virus can temporarily paralyze the
immune system, making that person more vulnerable to other infections.
We'll talk with one of the researchers about what they found.
