China - Bird Flu News Human Infection with Avian Influenza A(H7N9) Virus - China - 15 April 2015
CHINA - On 10 April 2015, the National Health and Family Planning Commission (NHFPC) of China notified WHO of 20 additional laboratory-confirmed cases of human infection with avian influenza A (H7N9) virus, including four deaths.
Onset dates ranged from 14 February to 21 March 2015. Cases ranged in age from 32 to 80 years with a mean age of 55 years. Of these 20 cases, 15 (75%) were male. The majority (18 cases, 90%) reported exposure to live poultry. One case is a health care worker, who had also poultry exposure. No clusters were reported. Cases were reported from five provinces: Anhui (3), Fujian (2), Guangdong (4), Shandong (1) and Zhejiang (10).

Global - Bird Flu News Study: H7N9 Adaptation in Mammals May Limit Transmission
GLOBAL - The genetic diversity of H7N9 avian flu viruses that infect ferrets —said to be a good model for human infection — is very limited, which might signify a "genetic bottleneck" to adaptation in mammals, according to a study in 'Nature Communications'. Researchers from St. Jude Children's Research Hospital in the US evaluated the replication efficiency, genetic diversification, and host adaptation of H7N9 virus after they inoculated chickens and ferrets and during ferret-to-ferret transmission. They showed that chickens, a natural H7N9 host, remained asymptomatic and that infection generated high genetic diversity.

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. Avian influenza virus spreads in the air and in manure and there is no evidence that the virus can survive in well cooked meat.

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
For more information on poultry vaccination see:

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.
