The Ministers shared their concerns about highly pathogenic avian influenza and recognized its growing threat to both human and animal health as well as to the broader security of the region.
Over the past four decades, only 18 outbreaks of highly pathogenic avian influenza, most caused by strains other than H5N1, have occurred throughout the world.
These outbreaks could either be new outbreaks of highly pathogenic avian influenza A(H5N1) virus, or, a continuation of the outbreaks first reported earlier in 2004.
The rapid spread of highly pathogenic avian influenza, with outbreaks occurring at the same time in several countries, is historically unprecedented and of great concern for human health as well as for agriculture.
Reports of highly pathogenic Avian Influenza epidemics in poultry, such as A(H5N1), can seriously impact local and global economies and international trade.
In all of these recent outbreaks, authorities have announced control measures in line with FAO and OIE recommendations for highly pathogenic avian influenza.
We recognize and appreciate the leading roles of the WHO, FAO, and OIE in the global response to highly pathogenic avian influenza, and in helping countries prepare for a potential human pandemic.
When the virus was allowed to continue circulating in poultry, it eventually mutated(within 6 to 9 months) into a highly pathogenic form with a mortality ratio approaching 100%.
According to the Ministry of the Environment, during the period from November 2016 to January 2017, viral infection of wild birds with highly pathogenic avian influenza was detected throughout the country.
An outbreak of highly pathogenic H7N7 avian influenza in birds, which began in the Netherlands in February 2003, caused the death of one veterinarian(from acute respiratory distress syndrome) two months later, and mild illness in 83 poultry workers and members of their families.
This characterisation of avian influenza viruses as low or high pathogenicity(severity of disease) is specific to poultry and other birds, and not necessarily to other species that can be susceptible to avian influenza viruses including humans.
The World Bank has called for increased vigilance on highly pathogenic bird flu, which has re-emerged in Hong Kong, Japan, Burma and South Korea since January, and has continued to circulate in Egypt, Indonesia, Bangladesh and other countries.
This result shows that highly pathogenic avian influenza(H5N1) and other subtype avian influenza viruses acquire human-type receptor binding specificity during circulation among livestock such as chicken, quail, turkey, and pig.
The Ministry of Agriculture China reported to World Organisation for Animal Health(OIE) on 21 February 2017 that genetic sequences of virus samples from live poultry markets in Guangdong also showed changes consistent with highly pathogenic avian influenza viruses.
The human seasonal virus(H1N1) that was used as control and the 2009 pandemic H1N1 virus preferentially bind to human-type receptors, whereas duck virus and highly pathogenic avian influenza H5N1 preferentially bind to avian-type receptors.
Health professionals are concerned that the continued spread of a highly pathogenic avian influenza virus among animals(mainly poultry) in Asia, Africa, the Middle East and Europe has the potential to significantly threaten human health.
During a 2003 outbreak of highly pathogenic avian influenza, caused by the H7N7 strain, in the Netherlands, more than 80 cases of conjunctivitis were detected in poultry workers, cullers, and their close contacts, and one veterinarian died.
From this fact, based on the"corresponding technical manuals relating to highly pathogenic avian influenza in wild birds"(hereinafter Manual), for the whole country of the corresponding level in wild bird surveillance currently being carried out is,"corresponding level 3 at the time of the domestic plurality of locations occurrence It will be.".
