Seasonality of respiratory syncytial virus in Buenos Aires. Relationship with global climate change

Abstract

Introduction.Global climate change circulation pattern respiratory syncytial virus (RSV). We assessed whether RSV season has changed over the past 20 years and its correlation with mean annual temperature. Methods. Cross-sectional study that included records of RSV and temperatures from Buenos Aires (1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014). RSV season onset, offset and duration, and its correlation with mean annual temperature were described for each year.

Respiratory Failure and Death in Vulnerable Premature Children With Lower Respiratory Tract Illness

“…The season ended when no patients were admitted with RSV LRTI to 4 of the 12 participating hospitals during the same week [ 13 , 15 ]. The duration of 3 seasons were 15 weeks, 17 weeks, and 16 weeks, respectively [ 18 ].…”

Viral respiratory infections in a rapidly changing climate: the need to prepare for the next pandemic

“…Recent epidemiological surveillance in temperate climates has revealed a shift in the peak timing of RSV seasonal activity towards warmer seasons over the past few decades, along with a shortened epidemic duration. 10 , 74 These trends are hypothesized to be associated with rising global temperatures leading to an expansion of the tropical belt. 75 However, confirming this hypothesis through empirical research is currently difficult due to the scarcity of long-term continuous surveillance data.…”

Dinámica de circulación de virus sincicial respiratorio y su relación con la temperatura ambiental. Serie de 25 años en Buenos Aires

“…Análisis: Para cada año, describimos el inicio, el fin y la duración de la temporada de VSR, calculados de acuerdo a lo consignado en un estudio anterior (6). Por otro lado, describimos las temperaturas medias, medias mínima y media máxima anuales de cada año.…”

“…Nosotros ya estudiamos la circulación del VSR en la Ciudad de Buenos Aires entre los años 1995 y 2014 (6) , encontrando que la temporada se ha ido acortando a lo largo de ese período. En este estudio buscamos extender ese análisis a un intervalo más extenso, que incluya el período pre-pandémico inmediato, de manera de contar con una sólida base para analizar el comportamiento del virus una vez finalizada la pandemia.…”
