Re: CDC - Influenza Epidemiology and Surveillance (through week 6) 2010
43 pages but almost all of them are graphs and tables.
Conclusion:
• H1N1 was widespread over most of the US and incidence has declined in recent weeks
• ILI Net rates were higher in October than they have been in any influenza season since surveillance began
– BRFSS -10% of adults and >20% children reported ILI in October
• Hospitalizations are highest in the youngest children and decline with age, excess hospitalizations are highest in the 5-17 year old age group
• Deaths are lowest in the youngest children and increase with age but only up to 50-64 year old age group --deaths decline in 65+ age group
• The majority of those hospitalized from flu have underlying conditions
– Asthma is common among those hospitalized
– Neurologic disorders are common among children dying from influenza
– Pregnant women are at high risk for severe outcome
• Racial ethnic disparities in severe outcomes persist and are under investigation
