- Clinical cases were notified from the abattoir with the observation of abnormal mortality.
- The local disease control center (LDCC) took and sent samples from the abattoir to the national laboratory (AHRI) for diagnosis.
- Because all the chickens of the index farm were delivered to the abattoir, the original native chicken farm was empty when LDCC traced back to conduct epidemiological investigation.
- The H5N2 subtype HPAI event was identified at the abattoir according to the results of investigation and laboratory tests (RT-PCR test, HA0 cleavage site sequencing and pathogenicity test).
