  • "Hemagglutinin and sialic acid have shapes that fit snugly together, and the hemagglutinin binds to the sialic acid 'receptor' like a hand going into a glove. As the virus sits against the cell membrane, more spikes of hemagglutinin bind to more sialic acid receptors; they work like grappling hooks thrown by pirates onto a vessel, lashing it fast."
