Approximately 861 cases of severe influenza, requiring ICU admission, occurred during the winter of 2010-2011, a number two times lower than the year before, we learn in the latest Weekly Epidemiological Bulletin (BEH ) on the balance sheet of the flu, a year after the pandemic.
In total, 2.78 million people who visited a general practitioner for influenza-like illness during the nine weeks of an epidemic, against 3.14 million French in 2009.
Another lesson of the study, more than 17 000 passages for emergency clinical influenza were recorded throughout the 2010-2011 season, including 919 hospitalizations. Senior citizens aged 65 and over appear to be the population most affected by these hospitalizations (29%), followed by children under 5 years (6%) and 15-65 years (4%) and 5-14 years (3%).
The greatest reduction in the number of severe cases of influenza admitted to the ICU in 2010-2011 for the 5-14 age group, say the authors, who explain it by an immunization acquired last year ', during the pandemic Influenza A (H1N1).
The acute respiratory distress syndrome was by far the most common complication (65%), followed by extracorporeal membrane oxygenation (ECMO), especially since the infection was caused by the influenza A (H1N1) viruses from the A (H3N2) or B This type of complication was also significantly more common among adults and the elderly than in children and adolescents.
Among the cases admitted to hospital, 64% had one risk factor for complicated influenza: 5% were obese and 20% were pregnant women.
The authors conclude that the good efficacy of the vaccine, estimated at 72% and even 80% among adults with a chronic disease, thus encouraging its use in people at risk. Among the severe cases for which information was available, there is still only 12% had received the flu shot.
The authors do, however, no link between the use of antiviral drugs early and severity of influenza, but recommend, however, their use in people at risk.
