摘要：The process of acquiring an infection has two components: first, exposure through proximity toanother infected individual, and second, transmission of the disease. Earlier studies of the socioeconomicfactors that affect the probability of acquiring an illness assume uniform exposure to infected individualsand may therefore result in biased estimates. This paper develops an empirical model, consistent withepidemiological models of spread of infections, to estimate the impact of socioeconomic variables on theextent of disease transmission within villages in Cambodia. Data from the 1997 CambodiaSocioeconomic Survey are used in this analysis.
