Sporadic H5N1 human infections continue; all linked to direct animal contact. Agricultural research workers, poultry handlers, and veterinary staff conducting field work face the highest occupational risk. Clade 2.3.4.4b dominant globally. Research staff working with live avian influenza virus must comply with FSAP registration requirements (H5N1 is a Select Agent). No sustained human-to-human transmission detected as of 18 May 2026.

Although antibodies against influenza A(H5N1) were detected in the index patient, serologic testing of a convenience sample of nine close contacts identified no detectable A(H5)-specific antibodies. Despite an extensive investigation, the infection source remains unknown; no human-to-human transmission was identified among close contacts by rRT-PCR and serologic testing.

HPAI A(H5N1) virus was detected in two indoor domestic cats with respiratory and neurologic illness that lived in homes of dairy workers but had no known direct exposure to HPAI A(H5N1)–affected farms.
