We rely on sentinels and the emergence of the H1N1 influenza strain further emphasizes your role in detecting the spread of influenza.
As the H1N1 virus appeared during the 2008-09 influenza season, sentinels were encouraged to collect specimens from patients presenting with symptoms of ILI during the summer as well as early in the 2009-10 influenza season to help us monitor the circulating influenza subtypes, including H1N1 and seasonal influenza subtypes, and also to evaluate both H1N1 and seasonal influenza vaccine performance (see below).
Now more than ever, during this critical post-pandemic influenza season, your participation in this surveillance system is needed to directly inform our clinical testing, vaccine implementation and management policies. The more you participate, the more precisely we can evaluate VE.
