摘要

Some host individuals tend to acquire parasites at a much faster rate than do others-a consequence of heterogeneities in susceptibility and/or exposure. This is termed 'overdispersion' and, as for many other statistical phenomena, the degree of overdispersion often conforms to a 20/80 rule, where 20% of the host population is responsible for similar to80% of the parasite transmission. But which are the hosts driving so much of the dynamics of an infectious disease? If host individuals at the tail of the frequency distribution can be identified by some common label, controlling parasitic diseases would be much easier. In two recent papers, Perkins et al. and Ferrari at al. have shown that male hosts are much more important than female hosts in the transmission of parasites.
