ABSTRACT

Recurrent acute viral fever (IVFR) in upper airways was studied in thirty-five children that attended private practice. Incidence, prevailing clinic syndrome and complications. Age from 1.6 to 3.6 years old, living in the metropolitan area of the Mexico’s City Valley, nineteen attending day care facilities (AE) and sixteen not attending day care. Method: Prospective open comparative observing method. Clinic registries done by one observer, during the autumn – winter of 2004 – 2005 and 2005 – 2006. Without vacations registry, two weeks during December 2004 – 2005 and spring – summer 2005. Results: The incidence and complications of IVFR increased, during 2004 – 2005 periods average otitis, sinusitis and bronchial hyperreactivity increased in AE children in comparison with NA children. Wilcoxon inter-groups p ‹ 0.05. The IVFR incident and its complications diminished during the autumn – winter period 2005 – 2006 in both AE and NA children, without changing the day care facility and home address in those two years, the children acquired type specific immunity, the incidence of fever viral re-infection diminished. The prevalent syndrome in both AE and NA groups was febrile acute nasofaringitis. The intra group U analysis of Mann-Whitney diminished, the intergroup diminished, and the Wilcoxon analysis, were p ‹ 0.05 significant. The bronchial hyperactivity increased during 2004 – 2005 and 2005 – 2006 due to hypersensitivity to the viral fever reinfection in both AE and NA groups with and statistic result of p ‹ 0.005. Conclusions: Children under three years old showed more IVFR, with an older age the incidence diminishes. The IVFR does not occur due to immune deficit, it is a previous absence of specific antigenic stimuli due to virus in both AE and NA groups during autumn – winter periods. The complications lessen when the IVFR incidence diminishes and increase the physiological inter-episode recovery period, larger than eight weeks.
