This study provides the first molecular characterization of duck hepatitis A viruses in Vietnam, identifying DHAV-3 as the dominant genotype.
Highlights DHAV-3 dominance in Vietnam; extends regional genotyping data but leaves open vaccine implications.
This is the first report of molecular characterization of DHAVs in Vietnam. At least two genotypes were identified, DHAV-1 and DHAV-3, with diversified clades within and between genotypes. DHAV-3 seemed to be dominant in Vietnam.
