By week 51 (from 20 to 26 December 2010), the incidence rate of consultations pour grippe clinique à partir des données du réseau unifié de Clinical consultations for influenza from data of the unified network grippe (données conjointes du réseau des Grog et Sentinelles) est de 286/ 100 flu (joint data network of Grog and Sentinels) is 286 / 100 000 [95% IC: 261-311] en nette augmentation par rapport aux semaines 000 [95% CI: 261-311] in sharp increase from the week précédentes (Figure 1). earlier (Figure 1).
...
By week 51, the proportion of positive samples for influenza Grog continues augmentation avec un taux moyen sur 2 semaines de 46% (Figure 4). increase with an average of 2 weeks of 46% (Figure 4)
...
The resumption of surveillance week 36 to week 51 * (balance of 27/12/10) 510 influenza viruses were detected in France by the laboratory of Virology and the National Reference Centers for Influenza Viruses (CNR) from samples community (or Network Grog Smog) or hospital (Renal Network). The distribution of virus in the general population is studied from samples real- by the Network of Grog has identified 240 influenza viruses since the beginning of the surveillance. monitoring. They are divided as follows: 116 (48%) influenza viruses type A: 28% A (H1N1) , 14% A (H3N2) and 6% A not subtyped, - 122 (51%) influenza type B. 2 (1%), influenza virus type C The NRC has antigenically characterized 98 of the 510 virus since surveillance began: 20 influenza A (H1N1) v, 21 influenza A (H3N2) viruses and 57 B, all related to vaccine strains, except one B virus Yamagata lineage. Influenza A (H1N1) v are susceptible to antiviral inhibitors of neuraminidase.

By week 51, 1225 passages ILI emergencies have been reported and 49 hospitalisations. 49 hospitalizations. The proportion of hospitalizations among the passages remains stable. hospitalizations for influenza has almost doubled compared to last week. The increase was more pronounced in the Ile de France where the number of passes and hospitalizations close to that observed at the peak in 2008 (Figure 5). Two severe cases (severity score ≥ 4) have been reported as part of this monitoring system during that week
...
Since monitoring began, the network of ICUs reported 15 cases graves (Figure 6). Taking into account the network coverage, the number of severe winter is lower than that observed in week 43 at the beginning of the epidemic wave in 2009
Among the 15 severe cases of the network, 8 were related to influenza A (H1N1), 1 influenza A (H3N2), 2 in virus B , 3 were awaiting typing and a case has not been confirmed.
Six people had no known risk factors. One patient was vaccinated. One patient died: she had no risk factors (Table 1). In parallel with this monitoring system, 10 other serious cases were spontaneously reported (9 related to influenza A (H1N1)) including 5 deaths (4 related to influenza A (H1N1)). Of the 5 deaths, 2 were risk factor, 2 did not and the information is unknown for one patient. Related to H1N1 infection, particularly when they involve a death, seem more easily menttion reported, which makes interpretation of these data difficult
