Abstract
Influenza‐associated respiratory illness was substantial during the emergence of the 2009 influenza pandemic. Estimates of influenza burden in the post‐pandemic period are unavailable to guide Kenyan vaccine policy.
To update estimates of hospitalized and non‐hospitalized influenza‐associated severe acute respiratory illness (
We used data from Siaya County Referral Hospital to estimate age‐specific base rates of
The mean annual rate of hospitalized influenza‐associated
The highest burden of disease was observed among children <2 years of age. This highlights the need for strategies to prevent influenza infections in this age group.
