  1. $refers to the peak epidemic months of the epidemic periods we defined (see methods and Figure 2); January 2008 - span December 2007 to February 2008, June 2008 – span April 2008 to September 2008, December 2008 – span November 2008 to March 2009, June 2009 – span April 2009 to August 2009, December 2009 – span November 2009 to January 2010, Mar 2011 – span December 2010 to August 2011. Inter-epidemic period cases were causes observed outside the above defined epidemic periods and these occurred between March 2010 and October 2010, and October and November 2011.
  2. #refers to the major epidemic peak month.
  3. §The numbers in the respective column of RSV group A and group B include 5 co-infections, thus the number identified and in total are increased by 5 over numbers of mono-infections referred to in the text. Only Group A viruses were possible to sequence from co-infections hence numbers of Group A sequenced are also 5 more than for mono-infections alone.
  4. *% Percentage of total group A and B identified that were group A.
  5. ¶refers to the average % genetic distance between the unique sequences which represent the % of nucleotide changes per every 100 nucleotides in the region between any the unique sequences.
