Influenza Surveillance
UNTIL 2011
Restricted to viral circulation
Irregular and heterogeneous
Provided restricted information for Surveillance and
Control Measures for Influenza and other respiratory
viruses.
We needed More samples, representativeness, virulence, subtyping
Guide antiviral treatment
Capacity to identify new viral subtype
