Monday, May 20, 2013 Human Infection with Avian Influenza A(H7N9) Virus – Update 17 May
CHINA - Since 8 May 2013, no new laboratory-confirmed cases of human infection with avian influenza A(H7N9) have been reported to WHO by the National Health and Family Planning Commission, China. However, four additional deaths have been reported from previously laboratory-confirmed cases.WHO
To date, WHO has been informed of a total of 131 laboratory-confirmed cases, including 36 deaths.
Authorities in affected locations continue to maintain enhanced surveillance, epidemiological investigations, close contact tracing, clinical management, laboratory testing and sharing of samples as well as prevention and control measures. In the past week, the Shanghai and Zhejiang provincial governments have started to normalize their emergency operations into their routine surveillance and response activities. WHO offices in country, regional and headquarters continue to work closely to ensure timely information updates.
Until the source of infection has been identified and controlled, it is expected that there will be further cases of human infection with the virus.
So far, there is no evidence of sustained human-to-human transmission.
WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions.
WHO continues to work with Member States and international partners. WHO will provide updates as the situation evolves.
Friday, May 17, 2013 Outbreak with a Novel Avian Influenza A(H7N9) virus in China - Scenarios and Triggers for Assessing Risks and Planning Responses in the EU, May 2013
EU - As part of the risk assessment and strategic planning related to the emergence of avian influenza A(H7N9) in China, Schenk and colleagues at the European Centre for Disease Prevention and Control (ECDC) has considered two major scenarios.Eurosurveillance Surveillance of Avian Influenza A(H7N9) Virus Infection in Humans and Detection of the First Imported Human Case in Taiwan, 3 April to 10 May 2013
The current situation is the one of a zoonotic epidemic (Scenario A) in which the virus might be transmitted sporadically to humans in close contact with an animal reservoir. The second scenario is the movement towards efficient human to human transmission (a pandemic Scenario B).
The authors identified epidemiological events within the different scenarios that would trigger a new risk assessment and a review of the response activities to implement in the European Union (EU).
They also identified the surveillance activities needed to detect these events.

Lo and colleagues at the Centers for Disease Control in Taipei, on 3 April 2013, suspected and confirmed cases of influenza A(H7N9) virus infection became notifiable in the primary care sector in Taiwan, and detection of the virus became part of the surveillance of severe community-acquired pneumonia.Eurosurveillance Human H7N9 Cases Linked to Poultry or Live Markets

(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 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
For more information on poultry vaccination see:
- 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
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.
