Migrants are subject to the diseases of both their host and home countries. In order to study the health consequences of migration, the morbidity, mortality, and fertility patterns of Quechua-speakers in lowland Bolivia were compared to those of Spanish-speaking inhabitants of the region. Quechua-speakers (mostly migrants) reported similar numbers of illnesses and disability days but significantly higher fertility and infant mortality rates than Spanish-speakers (mostly nonmigrants).
