Elodie Ghedin, Benjamin Cowling and colleagues quantify the frequency at which variants of influenza virus were transmitted between individual hosts during the 2009 H1N1 pandemic in Hong Kong. They find transmission of multiple variants between donor-recipient pairs and provide estimates of the number of viral particles that can infect and replicate within a host.
