CDC has sequenced the influenza viruses in specimens collected from the patient in Louisiana who was infected with, and became severely ill from HPAI A(H5N1) virus.

The genomic sequences were compared to other HPAI A(H5N1) sequences from dairy cows, wild birds and poultry, as well as previous human cases and were identified as the D1.1 genotype.

The analysis identified low frequency mutations in the hemagglutinin gene of a sample sequenced from the patient, which were not found in virus sequences from poultry samples collected on the patient’s property, suggesting the changes emerged in the patient after infection.

This is a technical summary of an analysis of the genomic sequences of the viruses identified in two upper respiratory tract specimens from the patient who was severely ill from an infection with highly pathogenic avian influenza (HPAI) A(H5N1) virus in Louisiana.

The patient was infected with A(H5N1) virus of the D1.1 genotype virus that is closely related to other D1.1 viruses recently detected in wild birds and poultry in the United States and in recent human cases in British Columbia, Canada, and Washington State.

This avian influenza A(H5N1) virus genotype is different from the B3.13 genotype spreading widely and causing outbreaks in dairy cows, poultry, and other animals, with sporadic human cases in the United States.
