Objectives for Part I
At the end of this training learners will be
able to:


Describe the causes and consequences of
the most frequent infectious diseases in
child care, and
Identify modes of transmission and
prevention of infectious diseases
transmitted by the respiratory route.
Percent of Children 1-6, By Type
of Care, 2001 (America’s Children 2003)
Infectious Disease in
Child Care





Increased frequency of illness
Greater severity of illness
More frequent antibiotic use
Increased risk for acquiring resistant
organisms
May carry home illnesses and infect
family members
Cost (in Millions) of Child Careassociated Illness1(Haskins, 1989)
Treatment of
respiratory infections
($78)
Treatment
of otitis
($420)
Absence
from work
($1,300)

Exclusion Criteria –

General Principles




Illness prevents the child from
participating
Illness results in a greater need for care
than staff can provide
Child is suspected by health authorities to
contribute to transmission of illness.
Fever with behavior changes, or signs and
symptoms of illness.

Prevention Strategies

Immunizations






Hib
Varicella-zoster
MMR, DTaP
Pneumococcus
Rotavirus
Health benefits of immunizations

Influenza vaccination of day care children is
effective in reducing influenza-related morbidity
among household contacts. (Hurwitz et al., 2000)
