Virus Characteristics

Details of the distribution of viruses detected in sentinel-source specimens can be found in the Primary care data section.

Non-sentinel virological data

Please refer to respective table and graph for additional information on non-sentinel specimens tested for influenza viruses this week.

Genetic characterization

Please refer to respective table for additional information on viruses that have been characterised genetically.

 

ECDC published the March virus characterisation report that describes the available data from circulating viruses collected after 31 August 2020.

This and previously published influenza virus characterization reports are available on the ECDC website.

 
 

 

Antiviral susceptibility of seasonal influenza viruses

Very few influenza viruses have been tested for susceptibility to neuraminidase inhibitors and sequence analysis indicated normal inhibition by both oseltamivir and zanamivir.
