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.
