    • The study reports infection of humans with highly pathogenic avian influenza A(H7N9) virus in Shaanxi, China, in May 2017. Complete genomes were obtained for samples from 5 patients and from live poultry markets or farms in four cities. Phylogenetic analyses support that the H7N9 LPAI viruses in Shaanxi Province originated from eastern and southern China, and the Shaanxi H7N9 HPAI isolates probably originated in Guangdong Province and were transmitted either directly or indirectly through other provinces.

    • The study aimed at understanding the classification, composition and distribution characteristics of avian influenza viruses in surveillance sites in Wenzhou, Zhejiang Province. A total of 1885 specimens were collected from the surveillance sites of poultry in Wenzhou area. Amongst the different results, the positive rates of H5, H7, and H9 subtypes were 9.8%, 15.3%, and 8.6%, respectively. The average positive rate of H7N9 in poultry sites was 11.6%.

    • The study aimed at understanding the infection status of avian influenza A virus in occupational exposure populations and external environments in Jiangyin. Environmental samples were collected from the external environment, with a total AIV positive rate of 48.87%. Occupationally exposed populations were asked to respond to a questionnaire and sampled to detect HI antibodies of avian influenza subtypes. The awareness about protection measures was found to be poor. The total positive rate of HI antibodies against avian influenza virus subtypes was 18.75%.

    • Based on an evolutionary analysis of H7N9 viruses from all five waves, the study showed that additional subclades of the H7 and N9 genes have emerged. Analysis indicates that H7N9 viruses inherited NP genes from co-circulating H7N9 instead of H9N2 viruses. Genotypic diversity among H7N9 viruses increased following wave 1, peaked during wave 3, and rapidly deceased thereafter with minimal diversity in wave 5, suggesting that the viruses entered a relatively stable evolutionary stage. The largest outbreak of wave 5 that was caused by the ZJ11 genotype may have been the consequence of a new constellation of genes rather than a single mutation.

New threats of H7N9 influenza virus: the spread and evolution of highly and low pathogenic variants with high genomic diversity in Wave Five. Journal of Virology. 2018 March 21. pii: JVI.00301-18. doi: 10.1128/JVI.00301-18. [reference].
    • In this study, the geographical distribution, phylogeny and genetic evolution of 240 H7N9 viruses in wave 5, including 35 new isolates, from patients and poultry in nine provinces, were comprehensively analyzed together with strains from the first four waves. The enhanced prevalence and diverse genetic characteristics with mammalian-adapted and NAI-resistant mutations may have contributed towards the increased number of human infections in wave 5.


FAO actions:

  • FAO published a risk assessment update entitled, “Chinese-origin H7N9 avian influenza: spread in poultry and human exposure” [reference]
  • FAO guidance and risk assessments are available on a dedicated website [link]
  • Liaise with China and partners, monitor situation, monitor virus evolution, conduct market chain analysis, risk assessment, surveillance guidance and communication.

  • Epidemiological comments   
    • Se recibió la notificación de mortalidad de aves de combate en un predio en Guanajuato; el propietario comentó haber participado en una competencia recientemente.
    • El aislamiento del virus en la muestra de Querétaro se obtuvo tras la notificación de un productor, que se ubica a 7 km del foco reportado anteriormente en ese estado.
    • Se trabaja en pruebas complementarias como IPIV y secuenciación.
    • En ambos casos, se implementaron actividades contraepidémicas como cuarentena de los predios y sacrificio de todas las aves; y por prevención, se establecieron un área focal de 3 km y una perifocal de 10 km, en donde se está llevando a cabo el muestreo correspondiente para comprobar la ausencia de enfermedad.
    • El Servicio Nacional Veterinario seguirá con la vigilancia epidemiológica e informará a la OIE de cualquier nuevo caso.
