#Uruguay - #Influenza A H5 viruses of high pathogenicity (Inf. with) (non-poultry including wild birds) (2017-) - Follow up report 1

 

    ° Following a suspicion regarding deaths among birds of various species, the Official Veterinary Service (SVO) launched an epidemiological investigation in a backyard in the Department of Colonia. 

    ° In the backyard there were birds of different species: hens (Gallus gallus domesticus), geese (Anser anser), and guinea fowl (Numida meleagris), which were raised outdoors and had contact with migratory wild birds. 

    ° Rapid tests came back negative, but samples were sent to the official laboratory to confirm the results, and they tested positive via PCR. 

    ° The SVO is currently conducting an epidemiological investigation in the zone. 

    ° On September 4, 5, and 6, the SVO conducted the epidemiological investigation in the area. 

    ° Activities included coordination, geographic delineation of the outbreak, establishment of a 5-kilometer operational radius, stamping out, sampling of birds, epidemiological investigation, and classification of establishments according to their risk level. 

    ° On September 5 and 6, 34 establishments within a 5-kilometer radius of the outbreak were inspected and identified. 

    ° No cases with compatible signs or mortality were reported within these establishments, nor were any commercial poultry farms listed in this area.

    ° A recurrence of high pathogenicity avian influenza (HPAI) subtype H5N1 (clade 2.3.4.4b) was detected in native chickens at a slaughterhouse in Taipei City, Chinese Taipei. 

    ° On August 8, clinical signs were identified during postmortem inspection by the resident veterinarian, who immediately notified the Local Animal Disease Inspection Authority of Taipei City. 

    ° On the same day, diagnostic samples were collected and sent to the National Reference Laboratory; concurrently, the other 25 native chickens from the same source were depopulated and placed in frozen storage. 

    ° Following official confirmation of the positive case on August 10, the frozen carcasses were destroyed on August 11, with cleaning and disinfection completed thoroughly. 

    ° Trace-back investigation was immediately initiated, and the source poultry farm was placed under movement restriction; subsequent diagnostic testing yielded negative results for avian influenza nucleic acid. 

    ° There are no poultry farms within 3 kilometers of the slaughterhouse.

#UK - Bovine spongiform encephalopathy #BSE - Immediate notification

    ° Isolated, single case of classical bovine spongiform encephalopathy (BSE) has been confirmed in a 7½- year- old indigenous cow on a beef suckler farm. 

    ° The cow was pregnant, with no clinical signs presented before being found dead. 

    ° The case was disclosed during routine national statutory surveillance and testing of fallen stock cattle aged over 48 months. 

    ° The animal was not presented for slaughter and did not enter the food chain. 

    ° There is no threat to food safety or human health. 

    ° A full epidemiological investigation is being carried out to identify relevant risk pathways for infection and any evidence to support these. 

    ° All of the cohorts and offspring of this single BSE case have been identified and placed under movement restrictions. 

    ° They will be culled and screened for BSE.

    ° This is the first detection of highly pathogenic avian influenza H5N1 clade 2.3.4.4b virus in New Zealand. 

    ° The detection is in a single subantarctic skua (Stercorarius antarcticus) found on Petone Beach, Lower Hutt. 

    ° The bird was found weak and emaciated and no neurological or respiratory clinical signs were observed. 

    ° Subantarctic skua are an ocean-going species. 

    ° Genomic sequencing indicates that the virus is closely related to H5N1 HPAI clade 2.3.4.4b viruses recently detected in Western Australia. 

    ° An epidemiological investigation is underway, and general surveillance is continuing. At this time, there is no evidence of further spread. 

    ° Vaccination of specific populations of threatened avian species is being initiated.

#Honduras - #Influenza A viruses of high pathogenicity (Inf. with) (non-poultry including wild birds) (2017-) - Immediate notification

 

    ° As a result of the strengthened epidemiological surveillance of avian influenza implemented by the National Agri-Food Health and Safety Services (SENASA), a report was received regarding an unusual increase in mortality among backyard birds in a community, associated with contact with wild birds. 

    ° In response, national protocols for addressing suspected cases of high pathogenicity avian influenza (HPAI) were immediately activated, including the conduct of an epidemiological investigation, sample collection, and the implementation of containment measures established in the National Contingency Plan. 

    ° Analyses conducted by the official laboratory confirmed the presence of the high pathogenicity avian influenza virus, prompting the implementation of the corresponding sanitary measures. 

    ° These included the culling of affected birds and susceptible birds (stamping out) on adjacent properties within the risk zone; the safe disposal of products and materials considered to pose a risk; as well as the cleaning and disinfection of the facilities and all potentially contaminated items, with the aim of reducing the risk of the virus spreading. 

    ° Additionally, SENASA has established an outbreak zone, a perifocal zone, and a surveillance zone around the confirmed outbreak, where intensified epidemiological surveillance, sampling of susceptible birds, epidemiological investigations, restriction of bird movement, and risk communication efforts targeting producers and the general public are being carried out; furthermore, the Ministry of Health has been notified to ensure a joint response to the event. 

    ° These activities aim to promptly detect any associated events and verify the effectiveness of the control measures implemented. 

    ° SENASA will continue epidemiological monitoring of the event until the activities established in the National Contingency Plan are completed and the absence of viral circulation in the affected area is demonstrated. 

    ° It will also keep producers, authorities, and the general public informed through periodic updates to the relevant reports.

    ° The affected population consisted of backyard birds, comprising susceptible domestic species raised in family-based production systems. 

    ° These birds were of various age groups and were in frequent contact with the outdoor environment, a condition that facilitates interaction with wild birds and increases the risk of exposure to the high pathogenicity avian influenza virus.

    As part of the epidemiological surveillance activities carried out by the Colombian Agricultural Institute, aimed at the early detection of clinical signs consistent with avian influenza, an outbreak of high pathogenicity avian influenza was confirmed in the village of Puerto Murillo, in the municipality of Puerto Carreño, Vichada Department. 

    The outbreak affects non-poultry birds in a backyard, in which digestive symptoms and mortalities were observed. 

    The National Veterinary Authority initiated screening and epidemiological monitoring efforts in the area of origin of the affected birds. 

    As a control measure, all the birds in the epidemiological unit were culled, and, in addition, epidemiological surveillance in the surrounding area was strengthened to identify other possible cases and prevent the spread of the outbreak.

    The animal health event occurred on a family subsistence farm (backyard) and affected only a flock of birds that, according to the definitions in the WOAH Terrestrial Animal Health Code, are not considered poultry, as they are intended solely for the household consumption without commercial purposes or links to livestock production chains. 

    The reported clinical picture was characterized by weakening, anorexia, profuse diarrhea, and high mortality following epidemiological contact with migratory wild birds.
