To investigate the potential contribution of public health surveillanc
e systems to the health of children and workers in out-of-home child-c
are settings, we review existing public health surveillance practice i
n the United States. We identify issues that are of particular concern
for surveillance in child-care settings. We propose a framework for d
eveloping public health surveillance systems that uses sentinel child-
care sites, notifiable disease surveillance, modification of existing
surveillance systems, and population surveys. Successful surveillance
in these settings depends on the active participation of child-care pr
oviders, public health practitioners, and clinicians in (a) the select
ion of high priority diseases and injuries for surveillance; (b) the d
evelopment of practical case definitions; (c) the augmentation of curr
ent surveillance systems to include disease and injury related to chil
d care; and (d) the implementation, assessment, dissemination, and eva
luation of new approaches for surveillance in child-care settings.
