Globally, the influenza pandemic delayed the onset of the first RSV season by 0.58\u2009months on average (95% CI: 0.42, 0.73; maximum delay: 2.5\u00a0months) and the onset of the second RSV season by a lesser extent (0.25\u2009months; 95% CI: 0.12, 0.39; maximum delay: 3.4\u00a0months); no delayed onset was observed for the third RSV season. The delayed onset was most pronounced in the northern temperate, followed by the southern temperate, and was least pronounced in the tropics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The 2009 influenza pandemic delayed the RSV onset on average by 0.58\u2009months and up to 2.5\u00a0months.
