Bangladesh - Bird Flu News Spread of Highly Pathogenic Avian Influenza (Subtype H5N1) Clades in Bangladesh 2010 and 2011
BANGLADESH - The spread of highly pathogenic avian influenza H5N1 in Bangladesh is characterised by reported long-distance translocation events. This poses a challenge to disease control efforts, according to lead author, Michael P. Ward.
Increased enforcement of biosecurity and stronger control of movements between affected farms and susceptible farms, and better surveillance and reporting, is needed.
Although the movement of poultry and equipment appears to be a more likely explanation for the patterns identified, the relative contribution of trade and the market chain versus wild birds in spreading the disease needs further investigation.

Bangladesh - Bird Flu News Surveillance of Avian Influenza Virus Type A in Semi-scavenging Ducks in Bangladesh
BANGLADESH - Based on our surveillance results, Amina Khatun from Chonbuk National University in Korea and co-authors concluded that semi-scavenging ducks in Bangladesh might play important role in transmitting Avian Influenza (AI) virus type A. However, the current risk of infection for humans from domestic ducks in Bangladesh is negligible.
The researchers say they believe that this relatively large data-set over three winters in Bangladesh might create a strong foundation for future studies of AI prevalence, evolution and ecology in wintering sites around the globe.

Bangladesh - Bird Flu News Molecular Epidemiology of Influenza A (H5N1) Viruses, Bangladesh, 2007–2011
BANGLADESH - To investigate the origins, evolution and patterns of spread of HPAI H5N1 outbreaks in Bangladesh, Md. Ahasanul Hoque of Chittagong Veterinary and Animal Sciences University performed a phylogenetic reconstruction analysis using Bayesian methods. The analysis was conducted using 81 haemagglutinin (HA) gene sequences from the H5N1 viruses isolated in Bangladesh from 2007 to 2011, together with 264 publicly available HA sequences of clade 2.2, 2.3.2 and 2.3.4 retrieved from GenBank. Our study provides evidence that clade 2.2.2 viruses that caused outbreaks in Bangladesh were lineages independent from the viruses introduced earlier into India. Furthermore, the Bangladesh clade 2.2.2 descendents subsequently spread to India and Bhutan.
This has implications for avian influenza control in southern Asia suggesting multiple routes of entry of the virus including one pathway that spread to neighbouring countries via Bangladesh.

Avian Influenza

(aka bird flu, avian flu) is caused by a type of influenza virus that is hosted by birds, but may infect several species of mammals. It was first identified in Italy in the early 1900s and is now known to exist worldwide. A strain of the H5N1-type of avian influenza virus that emerged in 1997 has been identified as the most likely source of a future influenza pandemic.Strains of avian influenza virus may infect various types of animals, including birds, pigs, horses, seals, whales and humans. However, wild fowl act as natural asymptomatic carriers, spreading it to more susceptible domestic stocks.

Diagnosis
How to Recognise Avian Influenza
What to look for
  • Ruffled feathers
  • Soft-shelled eggs
  • Depression and droopiness
  • Sudden drop in egg production
  • Loss of appetite
  • Cyanosis (purplish-blue coloring) of wattles and comb
  • Edema and swelling of head, eyelids, comb, wattles, and hocks
  • Green diarrhoea
  • Blood-tinged discharge from nostrils
  • Incoordination, including loss of ability to walk and stand
  • Pin-point hemorrhages (most easily seen on the feet and shanks)
  • Respiratory distress
  • Increased death losses in a flock
  • Sudden death
  • Nasal discharges

Poultry Vaccination

Poultry Vaccination as a strategy for controlling AI in commercial birds

Outbreaks of avian influenza in the poultry industry cause devastating economic losses and is generally controlled through extensive culling of infected birds. Alternative strategies also use vaccination as a supplementary control measure during avian influenza outbreaks.

.Advantages of Vaccination
  • Vaccination reduces susceptibility to infection.
  • A higher dose of virus is necessary to infect the vaccinated birds.
  • Vaccinated birds shed less virus.
    - Decreased contamination of the environment.
    - Decreased risk of human infection
  • Used strategically vaccination compliments a stamping out strategy by slowing/stopping the spread of the virus

Biosecurity

Avian Influenza (Fowl Plague) is a potentially devastating disease, predominantly of chickens and turkeys, although the virus can also affect game birds (pheasants, partridge and quail), ratites (ostrich and emu), psittacine and passerine birds.

Avian Influenza is caused by an orthomyxovirus, or influenza virus and can survive for considerable lengths of time outside of the host and birds are infected through contact with other birds, mechanical vectors such as vehicles and equipment and personnel travelling between farms, markets and abattoirs.

Precautionary requirements include cleaning and disinfection of premises and the establishment of a Biosecurity barrier to help prevent spread of disease is essential.
