Based on CDC statistics, confirmed cases of influenza-like illness (ILI) have declined for the second straight week, which experts believe is a sign the worst flu season in a decade has now peaked.
According to the latest CDC data, the percentage of outpatient visits attributed to influenza-like illness (ILI) — a key surveillance marker — dropped from 7.5% to 6.4% in the week ending Feb. 17. It peaked at 7.7% earlier this month, matching the highest level of the 2009 pandemic and setting a record for a nonpandemic season.
Influenza activity remained widespread in 48 states, according to the CDC data, with only Hawaii and Oregon continuing to see a break. ILI activity was still at the highest level in more than half of US states.
