“…Two well-designed cohort studies out of a series from the 1980s, 13 were conducted in Colombia and Uruguay, with respiratory symptoms being assessed during regular home visits by research nurses. 24,25 The reported mean numbers of acute respiratory tract infections per child during the first year of life (5.2 25 and 6. 6 24 ) is comparable to the mean of 5.2 weeks with symptoms in our study.…”

Summary. Respiratory symptoms are common in infancy. Nevertheless, few prospective birth cohort studies have studied the epidemiology of respiratory symptoms in normal infants. The aim of this study was to prospectively obtain reliable data on incidence, severity, and determinants of common respiratory symptoms (including cough and wheeze) in normal infants and to determine factors associated with these symptoms. In a prospective population-based birth cohort, we assessed respiratory symptoms during the first year of life by weekly phone calls to the mothers. Poisson regression was used to examine the association between symptoms and various risk factors. In the first year of life, respiratory symptoms occurred in 181/195 infants (93%), more severe symptoms in 89 (46%). The average infant had respiratory symptoms for 4 weeks and 90% had symptoms for less than 12 weeks (range 0 to 23). Male sex, higher birth weight, maternal asthma, having older siblings and nursery care were associated with more, maternal hay fever with fewer respiratory symptoms. The association with prenatal maternal smoking decreased with time since birth. This study provides reliable data on the frequency of cough and wheeze during the first year of life in healthy infants; this may help in the interpretation of published hospital and community-based studies. The apparently reduced risk in children of mothers with hayfever but no asthma, and the decreasing effect of prenatal smoke exposure over time illustrate the complexity of respiratory pathology in the first year of life.

“…During this study, two kinds of child populations were studied: a) children visited at home by pediatricians (group 1), and b) children with an ARI episode who attended an outpatient clinic (group 2). HRSV was the most frequently recovered viral agent detected, accounting for 67.9% in group 1 and 58.1% in group 2 (Hortal et al 1990). …”

“…Nuestros resultados confirman que la tasa de incidencia de infección respiratoria aguda es mayor en los niños que acuden a guarderías 5,11,12 en relación con la reportada y publicada en estudios de comunidad: cinco a seis infecciones por niño por año en Uruguay 13 fección respiratoria aguda de niños que asisten a guarderías fue de 14 episodios por niño al año, la cual fue sustancialmente mayor que la tasa de infección respiratoria aguda de niños cuidados en casa. La mayor incidencia reportada en estos centros, podría ser explicada por las características de estos ambientes, como serían sus condiciones higiénicas y el tener áreas pobremente ventiladas; estos factores facilitan la diseminación de patógenos respiratorios.…”

Objective. To assess the incidence of acute respiratory infections and bacterial colonization in children attending a daycare center. Material and Methods. A cohort study was conducted from April to Octuber 1999, among 85 children aged under four years, who attended the daycare center at Hospital Infantil de Mexico (Mexico City's Children's Hospital) "Federico Gómez". Acute respiratory infection incidence rates and quarterly point prevalence figures of nasopharyngeal colonization were obtained. Data were analyzed using descriptive statistics. Results. A total of 85 children were studied (40 girls and 45 boys) during 9 090 children-days of follow-up. Three children had a history of atopia (3.5%), six a history of asthma (7.%), and 39 (46%) were exposed to passive smoking. There were 258 events of respiratory tract infection for an incidence rate of 10.3 infections per person-year (95% CI 8.7-12.0). The main clinical syndromes were pharyngitis (95%), acute otitis media (3.5%), and bronchiolitis (1%). The incidence rates of otitis and bronchiolitis were 0.36 and 0.12 per child-year of observation, respectively. The prevalence figures of nasopharyngeal colonization for the three main bacteria were: S. pneumoniae 20.4%; nontypable H. influenzae 13%; and Moraxella catarrhalis 8%. Conclusions. Study results show a high prevalence of colonization due to invasive strains, as well as Este trabajo fue presentado en el 38
