Situation de la grippe aux Etats Unis :
https://www.cdc.gov/flu/weekly/index.htm
Outpatient ILI and laboratory data remain elevated and increased again this week. Nationally and in some regions the proportion of influenza A(H1N1)pdm09 viruses compared to influenza B viruses is increasing.
Overall, hospitalization rates remain similar to what has been seen at this time during recent seasons, but rates among children and young adults are higher at this time than in recent seasons.
Pneumonia and influenza mortality has been low, but 68 influenza-associated deaths in children have been reported so far this season.
CDC estimates that so far this season there have been at least 19 million flu illnesses, 180,000 hospitalizations and 10,000 deaths from flu.
Flu vaccine effectiveness estimates are not available yet this season, but vaccination is always the best way to prevent flu and its potentially serious complications.
Antiviral medications are an important adjunct to flu vaccine in the control of influenza. Almost all (>99%) of the influenza viruses tested this season are susceptible to the four FDA-approved influenza antiviral medications recommended for use in the U.S. this season.
