          Abstract

          OBJETIVO: Descrever o aumento do risco para aquisição de doenças infecciosas associado ao cuidado da criança fora do domicílio e a efetividade das medidas de controle para a prevenção da transmissão de doenças nas creches e pré-escolas. FONTES DE DADOS: Revisão das bases de dados MEDLINE, LILACS e Cochrane Library, através dos descritores creches, infecção, controle de infecção e doenças infecciosas, focalizada em estudos que comparam o risco de doença infecciosa em crianças cuidadas dentro e fora de casa, associam o risco às características do cuidado fora de casa e avaliam a efetividade de medidas de prevenção. SÍNTESE DE DADOS: As crianças cuidadas em creches ou pré-escolas apresentam risco de adquirir infecções aumentado em até duas a três vezes, com impacto na saúde individual e na disseminação das doenças à comunidade. O risco está associado, entre outros fatores, às características das creches, e medidas de prevenção simples são efetivas para diminuir a transmissão de doenças. Entre estas, recomenda-se: lavagem apropriada das mãos após exposição; utilização de precauções padrão; rotina padronizada para troca e descarte de fraldas usadas, localização e limpeza da área de troca, limpeza e desinfecção de áreas contaminadas; uso de lenços descartáveis para assoar o nariz; funcionários e área exclusivos para a manipulação de alimentos; notificação das doenças infecciosas; treinamento de funcionários e orientação dos pais. CONCLUSÕES: Diante da utilização crescente de creches e pré-escolas e da associação com risco aumentado de adquirir infecções, medidas de controle são imprescindíveis para a prevenção e controle das doenças transmissíveis.

          OBJECTIVE: To describe the increased risk of acquiring infectious diseases associated with out-of-home childcare and the effectiveness of measures for the control and prevention of diseases transmission at daycare and preschool education centers. SOURCES: A review of literature in the MEDLINE, LILACS and Cochrane Library databases, found using the descriptors daycare, infection, infection control and infectious diseases and focusing on studies that have compared the risk of infectious diseases for children cared for in and out of the home, related risk to the type of out-of-home care and assessed the effectiveness of preventative measures. SUMMARY OF THE FINDINGS: Children cared for at daycare or in preschool education exhibit a two to three times greater risk of acquiring infections, which impacts both on individual health and on the dissemination of diseases through the community. Among other factors, the risk is associated with the characteristics of daycare centers, and simple preventative measures are effective for reducing transmission of diseases. Recommended measures include: appropriate hand washing after exposure; employment of standard precautions; standardized routines for changing and disposal of used diapers, location and cleanliness of changing area, cleaning and disinfection of contaminated areas; use of disposable tissues for blowing noses; separate workers and area for handling foods; notification of infectious diseases; training of workers and guidance for parents. CONCLUSIONS: In the face of growing utilization of daycare and preschool education and their association with increased risk of acquired infections, control measures are indispensable to the prevention and control of infectious diseases.

          Cytomegalovirus and child day care. Evidence for an increased infection rate among day-care workers.

          Lynn Adler (1989)
          To determine whether day-care workers acquire cytomegalovirus infection from the children they care for, we studied 610 women employed at 34 day-care centers over two years. Forty-one percent of the caretakers were seropositive for cytomegalovirus. After adjustment for the effects of race, marital status, and age on seropositivity, the women who cared for children younger than two years of age had a significantly higher seropositivity rate (46 percent) than the women who cared for children older than two years of age (35 percent) (relative risk, 1.29; 95 percent confidence interval, 1.05 to 1.57; P less than 0.02). Of 202 initially seronegative caretakers (observed for an average of 305 days per woman), 19 seroconverted, for an annual seroconversion rate of 11 percent. This rate was significantly higher than the 2 percent annual rate of seroconversion among 229 seronegative women (11 of whom seroconverted) in a comparison group of female hospital employees observed for an average of 781 days per woman (relative risk, 5.0; 95 percent confidence interval, 2.4 to 10.5; P less than 0.001). At three day-care centers in which the children were also studied, seven of the nine women shed isolates of cytomegalovirus in their saliva or urine that had EcoRI and BamHI DNA-digestion patterns identical to the DNA patterns of isolates shed by one or more children in their care. We conclude that workers in day-care centers may acquire cytomegalovirus infection from the children in their care and that this risk is significantly greater among those who care for children less than two years of age.

            Infectious disease in pediatric out-of-home child care.

            Provision of some form of child care outside of the home is certainly not a new phenomenon. In the past, most out-of-home care was provided by a relative, a friend, or someone who had a specific relationship with the family of the child. The frequency of utilization of child care centers for out-of-home care and the different formats of out-of-home care services has increased within recent decades and will vary by geographic location. Also, there is an increased utilization of temporary child care such as "mother's day out" or baby-sitting services provided at churches, grocery stores, and other places. Child care centers represent special risks for transmission of infectious agents because young children exhibit high susceptibility to many community-acquired viruses and bacteria; they lack developmental understanding required for good hygiene; and they frequently receive antibiotics (appropriately and inappropriately). Infections acquired in child care centers can significantly impact the health of the children who acquire the infection and also result in significant economic impacts on the child's family, particularly if 1 or more of the parents has to lose time from work. In the United States, it is estimated that families who have children in child care lose 13 days of work per year for all types of infections. Interventions that have proven valuable for reducing infections within child care centers include the following: (1) formal written policies for infection control within the child care center, (2) formal education of child care center staff concerning infection control practices (needs to be repeated; preferably on a recurring basis), (3) good hand hygiene by both staff and children, (4) appropriate cleaning of contaminated surfaces, (5) separation of food preparation and diaper changing, (6) exclusion of certain ill children, (7) cohorting ill children when exclusion is not possible, (8) ensuring adequate age-appropriate immunization of child care attendees and staff, and (9) optimal ratios of children to staff.

              Risk factors for primary invasive Haemophilus influenzae disease: increased risk from day care attendance and school-aged household members.

              From November 1, 1981, through April 30, 1982, we performed a case-control study of primary invasive Haemophilus influenzae infections in children in Colorado. Information was collected for 121 (83%) of 146 children with positive cultures and for 196 (67%) of 292 age-matched controls selected at random from birth certificates. Infected children were more likely to have attended a day care center or nursery (DCC/N) and to have an elementary school-aged household member. For attendance at DCC/N, the relative risk was significantly increased only for children 12 months of age or older, and increased with the size of the DCC/N. After controlling for DCC/N attendance and school-aged siblings, children younger than 6 months of age with infection were significantly less likely to have been breast-fed, suggesting a protective effect of breast-feeding. We identified DCC/N attendees, especially those older than 1 year of age, to be at increased risk of primary H. influenzae disease. They could benefit from immunization.
