symbolically New findings, reported in the journal Respiratory Research, about how the bird flu virus binds to the respiratory tract and lung suggest children may be particularly susceptible to avian influenza.

Different types of sialic acid attract different types of influenza virus. Once the virus finds sialic acid, it can attach and infect the cell. The distribution of sialic acid molecules affects how likely the virus is to find cells to infect.
