The HA gene sequence confirms which the virus is clade 2.3.4.4b, plus the NA sequence was verified as N1. There are two amino acid variances in the HA that have not been seen in sequences from preceding human conditions. These amino acid variances aren't known to get linked to adjustments towards the virus's power to infect and spread between people.
