Influenza A(H3N2)v laboratory detection questionnaire results

Technical report

Following the emergence of swine influenza A(H3N2) variant (v) viruses with sporadic human infections in North America, ECDC and the Community Network of Reference Laboratories (CNRL) disseminated a questionnaire to explore the RT-PCR capability of influenza reference laboratories in EU/EEA countries to detect A(H3N2)v viruses in their day-to-day diagnostics and to subtype them as swine-origin variant viruses. The results showed that while laboratories have a good capability to do the former, the latter remains more challenging.
