- Unknown or inconclusive
- Source of the outbreak(s) or origin of infection
- Epidemiological comments
- In the secondary outbreak HPAI subtype H7 has been detected at RT-PCR and no clinical signs have been identified.
- Restriction zone has been established, depopulation will be carried out and epidemiological investigation is on-going.
- The depopulation operation in the primary outbreak, in Ostellato, Ferrara province, will be completed today 21 August, followed by cleaning and disinfection.
- The National Reference Laboratory in Padova confirmed that the virus isolated is an HPAI H7N7 showing an IVPI 3,0.
- Genome sequencing as well as the epidemiological investigation are ongoing.
- Preliminary information would suggest that a LPAI virus entered the farm (possibly via wild birds) where it mutated to a HPAI strain.
