Outbreaks There are no new outbreaks in this report
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments - The H5N8 subtype of viruses have a series of basic amino acid at the hemagglutinin (HA) cleavage site such as LREKRRKR/GLF or LRERRRKR/GLF, which means highly pathogenic to chickens. - The intravenous pathogenic index was 3.0, which means highly pathogenic to chickens. Animal and Plant Quarantine Agency (QIA) injected intravenously 0.1ml of the 1/10 diluted virus into each of ten 6-week-old SPF chickens. All birds were died within 24 hours. - QIA submitted the genetic information to GenBank and submitted manuscript to scientific society (Emerging Infectious Disease, MS#EID-14-0233) about the brief situation of outbreaks and the genetic information on 27 January 2014.
