    Re: 2009 Influenza Sentinel Surveillance - ESR

    compare newflu with oldflu.
    oldflu seems to have peaked earlier
    But typically a wave takes ~10weeks so this is probably due to newflu
    suppressing oldflu (by host immunity)

      If the non sentinel results are taken from people who are ill, it shows the novel h1n1 is causing more severe illness than the seasonal flu (it shows a higher proportion of novel)

        The latest graph of cases shows a distinct dip in the week 20 -26 July following, to a certain extent, the seasonal trend . The novel pandemic a/h1n1 is now the predominant strain but still remains sensitive to Tamiflu.

              Graph shows consultations still approx double the normal seasonal amount.

                2009 Influenza Sentinel Surveillance - ESR

                There has been a decrease in consultations for influenza-like illness through sentinel surveillance in week 43 (19-25 October 2009).

                Up to 25 October 2009, a total of 4879 influenza viruses have been reported through sentinel (622, 13%) and non-sentinel surveillance (4257, 87%). Four influenza viruses were reported in week 43: two as pandemic (H1N1) 09 and two as A (not sub-typed) from the non-sentinel surveillance. Pandemic (H1N1) 09 has become the predominant strain among all influenza viruses. Seasonal A (H1N1) strain has been the predominant strain among all seasonal influenza viruses.

                  Sharp uptick in consultation rates, has surpassed 2008 levels already.
                  The majority of viruses were Pandemic (H1N1) 09 (207, 72%)
