Infectious diseases in day-care centers: transmission and approaches to prevention.

Child day care is used increasingly by both single-parent and two-parent families. With the growth in numbers of children receiving day care outside the home comes a greater awareness of the potential for disease transmission. Epidemiologic patterns of spread of such diseases as Hemophilus influenzae type b, hepatitis A, diarrheal diseases, and cytomegalovirus are changing with respect to attendance at a day-care center. Not only is this a problem for the staff and children who attend a center, but it also may be a public health concern as these diseases could spread to households and the community at large. This review will identify those transmissible infectious agents frequently found in children who attend day-care centers with an emphasis on approaches to prevention and methods for decreasing secondary spread.
