“…H9N2 viruses are considered endemic in China, Vietnam and South Korea (see Table 1, Figure 1) [5,18,19,20]. In recent years, the virus has been isolated for the first time in Cambodia, Myanmar, Indonesia, Malaysia and the Russian Far East and serological evidence suggests the virus may also be present in poultry in Laos and Thailand [21,22,23,24,25,26,27,28]. BJ94 lineage viruses are found throughout China, Vietnam, Cambodia, Myanmar and Indonesia.…”

H9N2 avian influenza viruses have become globally widespread in poultry over the last two decades and represent a genuine threat both to the global poultry industry but also humans through their high rates of zoonotic infection and pandemic potential. H9N2 viruses are generally hyperendemic in affected countries and have been found in poultry in many new regions in recent years. In this review, we examine the current global spread of H9N2 avian influenza viruses as well as their host range, tropism, transmission routes and the risk posed by these viruses to human health.

“…Recent study revealed that the HA gene of Indonesia H9 formed a distinct cluster with some H9 from China and Vietnam. Thus, a novel China–Vietnam–Indonesia (CVI) lineage was proposed for well‐supported divergence from other lineages (Jonas et al, ). However, this study could not prove where and how H9N2 circulate in the first place in Indonesia.…”

“…In 2016, Indonesia has faced another challenge of LPAI‐H9N2 outbreaks in poultry. The LPAI‐H9N2 caused mortality and/or production losses in broiler and layer chicken (Jonas et al, ). In 2018, recent study reported LPAI‐H9N2 virus isolated from chicken in a live poultry market (Novianti et al, ).…”

“…LPAI‐H9N2 also caused influenza outbreaks in duck farms in Yogyakarta province resulting in the death of approximately 1,000 ducks. Co‐circulation of either subclades or subtypes of avian influenza has been reported in Indonesia (Jonas et al, ; Karo‐Karo et al, ); therefore, this study aimed to identify and characterize the whole genome of avian influenza viruses isolated from ducks in the same farm during an avian influenza outbreak in Yogyakarta province, Indonesia.…”

In July 2016, an avian influenza outbreak in duck farms in Yogyakarta province was reported to Disease Investigation Center (DIC), Wates, Indonesia, with approximately 1,000 ducks died or culled. In this study, two avian influenza (AI) virus subtypes, A/duck/Bantul/04161291‐OR/2016 (H5N1) and A/duck/Bantul/04161291‐OP/2016 (H9N2) isolated from ducks in the same farm during an AI outbreak in Bantul district, Yogyakarta province, were sequenced and characterized. Our results showed that H5N1 virus was closely related to the highly pathogenic AI (HPAI) H5N1 of clade 2.3.2.1c, while the H9N2 virus was clustered with LPAI viruses from China, Vietnam and Indonesia H9N2 (CVI lineage). Genetic analysis revealed virulence characteristics for both in avian and in mammalian species. In summary, co‐circulation of HPAI‐H5N1 of clade 2.3.2.1c and LPAI‐H9N2 was identified in a duck farm during an AI outbreak in Yogyakarta province, Indonesia. Our findings raise a concern of the potential risk of the viruses, which could increase viral transmission and/or threat to human health. Routine surveillance of avian influenza viruses should be continuously conducted to understand the dynamic and diversity of the viruses for influenza prevention and control in Indonesia and SEA region.
