Children under 3 years of age who are in group care face special health risks. The U.S. Centers for Disease Control indicate the existence of a causal relationship between infant group day care and certain diseases that are spread through contact at day care centers. Children in group care who are still in diapers are especially vulnerable to hepatitis A, diarrheal diseases, and Hemophilus influenzae type b. Adults who contact these children are also especially susceptible to these diseases. Preventive measures include home care for non-toilet-trained children and scrupulous hand washing when infants are cared for in groups. Infant caregivers need information about precautions and appropriate procedures. Policy recommendations include: (1) improved state and federal regulation; (2) subsidy of infant day care; and (3) increased use and support of home care options. Nearly 50 references are cited.
