Emerg Infect Dis. 2018 Jun;24(6):1103-1107. doi: 10.3201/eid2406.172099.

Abstract

In January 2017, an estimated 3,700 (93%) of 4,000 Khaki Campbell ducks (Anas platyrhynchos domesticus) died in Kampong Thom Province, Cambodia. We detected low pathogenicity avian influenza A(H7N3) virus and anatid herpesvirus 1 (duck plague) in the affected flock; however, the exact cause of the mortality event remains unclear.

Keywords: AIV; Cambodia; H7N3; LPAI; LPAIV; avian; ducks; influenza; low pathogenicity; mortality event; poultry; viruses; zoonoses.
