*Lab confirmed cases of influenza are only the ?tip of the iceberg?, representing a fraction of individuals infected. Laboratory testing is reserved for patients admitted to hospital with respiratory infection. Because we do not routinely test community specimens, the number of laboratory

**Deaths include individuals with a positive influenza test result. For some individuals with pre-existing conditions, influenza may not have been the major contributing cause of death or hospitalization.
