^aNumber of laboratories providing votes on the transmissibility of the tested virus is shown. Each laboratory will vote if the tested virus possesses moderate to high transmissibility (P ≥ 50%, i.e., ≥2 infected out of 4 ferrets) or low transmissibility (P ≤ 25%, i.e., 0 or 1 infected out of 4 ferrets) based on the experimental result.

^bConcordant result that supports either moderate to high or low transmissibility across participating laboratories.
