Respiratory tract viral outbreaks, particularly among infants\n who required \nhospitalization, were found to be associated mainly with respiratory syncytial\n (RSV) infections \n(72%), influenza (11%) and parainfluenza viruses (11%). Consistent seasonal\n variations in \nviral infections were observed only with RSV (March\u2013August) and influenza\n A virus (peaks in \nJune, December\u2013January). The RSV trends were associated with higher\n environmental \ntemperature, lower relative humidity and higher maximal day-to-day temperature\n variation. \nAlthough the influenza A outbreaks were not associated with meteorological\n factors, influenza \nB isolates were positively associated with rainfall. These data \nsupport the existence of seasonal \ntrends of viral respiratory tract infections in the tropics.<\/jats:p>","DOI":"10.1017\/s0950268898008905","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:23:42Z","timestamp":1027776222000},"page":"121-128","source":"Crossref","is-referenced-by-count":243,"title":["Seasonal trends of viral respiratory tract infections in the tropics"],"prefix":"10.1017","volume":"121","author":[{"given":"F.
