Abstract
Ecology of Diarrhea: Rotavirus is an important cause of morbidity and mortality globally, and, although the infection takes a terrible toll on infant lives, its epidemiology is rather poorly known. New vaccines have become available and are being introduced in the United States prior to global rollout, but they may have some unexpected effects on disease dynamics. Pitzer et al. (p. 290 ; see the Perspective by Medley and Nokes ) analyzed data and developed models describing the epidemiology of rotavirus before and during adoption of the vaccine. Ecological analysis showed that the birth rate predicted the timing of epidemics much better than climatic variables and that shifts in birth rates explained changes over the years. But as increasing numbers of infants are vaccinated, the pool of susceptible individuals in the population will be reduced, which will affect the annual waves of geographic spread of rotavirus.This publication has 31 references indexed in Scilit:
