CNRL in silico exercise to determine the capabilities of network laboratories to detect triple reassortant swine origin influenza A(H3N2) viruses

Following the emergence of swine influenza A(H3N2) variant (v) viruses with sporadic human infections in North America, the Community Network of Reference Laboratories (CNRL) and the Animal Health and Veterinary Laboratories Agency completed an exercise to assess the CNRL's capability to detect novel reassortant and circulating triple reassortant swine viruses (TRA) in humans. A questionnaire was distributed by ECDC to 35 laboratories in 29 countries. The exercise proved to be useful in highlighting development requirements and gaps in detection and identification capabilities for potential emerging A TRA viruses of swine origin.
