“…These data have been reported in other investigations with regard to low temperature [5-9, 11, 13, 15-17], low relative humidity [6,9,10] and clear skies [20]. However, in other studies a relationship has been found between the number of admissions and high temperature [10,11,14], high relative humidity [12] and low [4] or high rainfall [14,17]; these results have been reported more frequently in tropical climates.…”

“…Despite these monthly variations during the last 20 years there has been little documentation of this, only about 15 articles, which analyse the influence of climatic factors on lower respiratory tract infection due to RSV [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and only one of them has been carried out in Europe [20].…”

“…Studies from subtropical climates in South America and China report an association with relatively low temperatures; however, this was not apparent in our study. This may be because the average minimum temperature on the Gold Coast does not fall as low as temperatures in these other sites [29][30][31][32][33][34]. One review of cities with similar climates found RSV activity peaked in cities when the mean temperatures were about 1-14°C in the coldest months, which is colder than the Gold Coast winter [7].…”

Evidence is emerging regarding the influence of meteorological factors on seasonal respiratory syncytial virus outbreaks. Data however, are limited for subtropical regions, especially in the southern hemisphere. We examined whether meteorological data (daily minimum and maximum temperatures, rainfall, relative humidity, dew point, daily global solar exposure) and tourist numbers were associated with the incidence of RSV in children aged <5 years for the Gold Coast region of South-East Queensland, Australia (latitude 28.0°S). RSV cases between 1 July 2007 and 30 June 2016 were identified from the Pathology Queensland Gold Coast Laboratory database. Time-series methods were used to identify seasonal patterns. RSV activity peaked in mid-to-late autumn (April-May), tapering in winter (June-August). While most meteorological variables measured were associated with RSV incidence, rainfall (ρ = 0.40, 95% confidence interval (CI) 0.32-0.48) and humidity (ρ = 0.38, 95% CI 0.29-0.46) 8 weeks earlier had the nearest temporal relationship. Tourist numbers were not correlated with RSV activity. Identifying meteorological conditions associated with seasonal RSV epidemics can improve understanding of virus transmission and assist planning for their impact upon the health sector, including timing of passive RSV immunoprophylaxis for high-risk infants and future public health interventions, such as maternal immunisation with RSV vaccines.

Human Respiratory Syncytial Virus (HRSV) is recognized as the single most important pathogen responsible for acute viral infection of the lower respiratory tract in young children. In this study, 84 samples from children under two years of age presenting acute respiratory symptoms were obtained from September 2000 to November 2001. Analysis by immunofluorescence and reverse-transcription followed by PCR, revealed that 18% (15/84) of all the samples were positive for HRSV, in which 80% (12/15) of the cases was observed in children under six months of age and the subgroups A and B co-circulated in the studied period. These are the first data obtained for Botucatu city and seasonality is evident by the higher circulation of the virus between May and July.
