bull From 2011 a new genotype of H5N1 viruses with PB1 gene of H9N2 virus circulated in Indo-gangetic plains

bull In June 2015 a new genotype of H5N1 viruses clade 2321a identified in Bangladesh with the HA NA and M genes of circulating 2321a H5N1 viruses and five other genes of LPAIVs (Eurasian-lineage)

bull In India similar viruses were isolated in 2006 and caused recent outbreaks in 2016-2017 except in the state of Karnataka in May 2016

Antigenic divergence of H5N1 viruses

bull Cross hemagglutination inhibition data

indicated antigenic divergence (6-21 fold reduction in

cross-reactivity) between the two recently emerged

H5N1 clades 2321a and 2321c

bull These two clades are highly divergent (21-128 fold

bull The Bangladeshi H9N2 viruses (2009-2013) clustered with the H9N2 viruses isolated from India Pakistan and the Middle East

bull In the HA tree all of the H9N2 viruses formed a well-supported monophyletic cluster (99 bootstrap value) in the Mideast B sublineage

bull The HA gene of H9N2 viruses

bull Sublineage B1 -viruses collected

bull Sublineage B2 - viruses collected

from 2008 to 2015 and clustered

with viruses identified from the

Indian subcontinent

Dong-Hun Lee et al Vet Rec Open 2016 3(1) e000171

bull Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010 and role of wild birds are suspected (Pandit et al 2013)

bull H5N8 viruses isolated from wild birds and poultry in India during Oct-Dec 2016 are related to Uvs-Nuur lake-like virus (isolated in May 2016) and coincides with winter migration of birds indicating role of wild birds in the dispersal of virus (Nagarajan et al2017 Sims et al 2016)

Wild birds and avian influenza outbreaks

Central Asian Flyway

bull Eight Bird flyways ndash across the

world

bull Central Asian flyway (extends

bull Movement of wild waterfowls was

suspected in intercontinental

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

mind while advocating the same

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

mind while advocating the same

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

mind while advocating the same

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

bull Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010 and role of wild birds are suspected (Pandit et al 2013)

bull H5N8 viruses isolated from wild birds and poultry in India during Oct-Dec 2016 are related to Uvs-Nuur lake-like virus (isolated in May 2016) and coincides with winter migration of birds indicating role of wild birds in the dispersal of virus (Nagarajan et al2017 Sims et al 2016)

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

mind while advocating the same

Thank you for kind attention

bull From 2011 a new genotype of H5N1 viruses with PB1 gene of H9N2 virus circulated in Indo-gangetic plains

bull In June 2015 a new genotype of H5N1 viruses clade 2321a identified in Bangladesh with the HA NA and M genes of circulating 2321a H5N1 viruses and five other genes of LPAIVs (Eurasian-lineage)

bull In India similar viruses were isolated in 2006 and caused recent outbreaks in 2016-2017 except in the state of Karnataka in May 2016

Antigenic divergence of H5N1 viruses

bull Cross hemagglutination inhibition data

indicated antigenic divergence (6-21 fold reduction in

cross-reactivity) between the two recently emerged

H5N1 clades 2321a and 2321c

bull These two clades are highly divergent (21-128 fold

reduction in HI titre) from the earlier clades 22 2221

H9N2 AIV - Pakistan

bull The HA gene of H9N2 viruses

from 2008 to 2015 and clustered

with viruses identified from the

bull Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010 and role of wild birds are suspected (Pandit et al 2013)

bull H5N8 viruses isolated from wild birds and poultry in India during Oct-Dec 2016 are related to Uvs-Nuur lake-like virus (isolated in May 2016) and coincides with winter migration of birds indicating role of wild birds in the dispersal of virus (Nagarajan et al2017 Sims et al 2016)

Conclusionbull HPAI H5Nx virus is a regional problem and only country specific

control measures will not be effective

bull The H5N1 and H9N2 viruses are evolving continuously in the

SAARC region

bull Cultural and economic factors lead to close interaction of

human and poultry in this region and hence there is a need for

targeted and coordinated active surveillance

bull Strengthening surveillance of avian influenza in poultry wild

birds and other hosts is important to assess their impact on

animal health

bull Creating awareness about biosecurity and its implementation is

essential However cost of such measures need to he kept in

mind while advocating the same

Antigenic divergence of H5N1 viruses

bull Cross hemagglutination inhibition data

indicated antigenic divergence (6-21 fold reduction in

cross-reactivity) between the two recently emerged

H5N1 clades 2321a and 2321c

bull These two clades are highly divergent (21-128 fold

reduction in HI titre) from the earlier clades 22 2221
