Bird flu confirmed in West Bengal district

India Blooms News Service


Kolkata, Sept 20 (IBNS) Fresh cases of bird flu were reported from West Bengal's southern district of Nadia, official reports said on Tuesday.

Though the cases were not yet alarming, the fear of a bird flu (H5N1) was confirmed by the laboratory in Bhopal.

Culling of poultry birds like chicken and ducks by veterinary workers would begin in an area covering about 25 villages.

Bird flu first broke out in India in 2006 while in West Bengal it was first reported in 2007 and in a large scale in 2008 when several districts were affected, leading to the culling of over four million poultry birds.

Avian flu had spread to 11 districts of West Bengal in 2008.

Birbhum, South Dinajpur, Murshidabad, Nadia, Burdwan, Bankura, Malda, Hooghly, Cooch Behar, Purulia and Howrah were worst affected.

India has reported no human infections.

Influenza A virus subtype H5N1, also known as "bird flu", A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species.

A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu, commonly known as "avian influenza" or "bird flu".

Most human contractions of the avian flu are a result of either handling dead infected birds or from contact with infected fluids. :tiphat:http://www.indiablooms.com/NewsDetailsPage/newsDetails200911a.php

New virus: India to start culling birds

2011-09-20
New Delhi - Authorities in eastern India will start culling chickens and destroying eggs to contain a new outbreak of H5 bird flu, the government said on Tuesday, as a mutant strain of the virus is spreads elsewhere in Asia.

Surveillance was stepped up in West Bengal, a state severely hit by bird flu outbreaks in the past.

The federal government is pushing local authorities to ban the movement of poultry and its products, and restricting access to the affected area after samples tested positive for H5, a government statement said.

"It has been decided to immediately commence the culling of birds and destruction of eggs and feed material to control further spread of the disease," it said.

Last month, the UN Food and Agriculture Organisation (FAO) warned of a possible resurgence of bird flu and said a mutant strain of the H5N1 virus was spreading in Asia and beyond.

It was not immediately clear if the latest outbreak in India was related to the new Asian strain.

Virologists warn there is no vaccine against the H5N1 strain recently found in China and Vietnam that could potentially carry risks for humans and called for closer monitoring of the disease in poultry and wild birds to stop it spreading.

Bird flu first broke out in India in 2006 and millions of chickens and ducks have been culled since to contain the virus, but it has resurfaced from time to time.

India did not give further details about the exact strain of flu found in the latest outbreak West Bengal.

Bird flu in West Bengal; govt orders culling
Krishnagar (WB), Sept 20
Culling of birds began today at Tehatta 1 block in Nadia district after confirmation of the outbreak of Avian Influenza, popularly known as Bird Flu. Symptoms of Avian Influenza were initially observed among hens in 13 villages under 5 Gram Panchayat areas of Tehatta 1 block about 10 days back.
The samples of the birds were collected and sent to High Security Animal Disease Laboratory (HSADL) Bhopal for tests.
"The report arrived at around 6.30 pm yesterday confirming Bird Flu. We decided to start culling and it was initiated today," Nure Alam Chowdhury, Animal Resource Department Minister told a press conference after visiting the affected block here today.
Twenty teams comprising 420 persons were deployed in the process of culling scheduled in 5 gram panchayat areas. After culling, the dead birds will be buried at Lalbazar, a place near Indo-Bangladesh border. Three big holes were dug up for the disposal of the culled birds here, he said.
Tehatta SDO Achinta Mondal said "we hope to cull about 5000 birds today and the culling work will go on up to 7 pm and the culled birds will be buried".
The minister arrived at Tehatta today morning and visited some of the affected places.
Meanwhile the Indo-Bangla border has also been sealed, the minister said.
Official reports said culling will continue for three consecutive days. During this period, movement of people deployed in culling also have been restricted outside the area. They have been provided with special uniform.
The SDO said the tyres of the vehicles moving through the areas would be disinfected. About 300 vehicles cross the area on an average everyday along the Krishnagar-Karimpur road.
There is a vast waterbody at Tehatta where some migratory birds come during winter. The minister suspected the migratory birds might have left behind the germs of Bird Flu.
The minister said "there is no need to get into panic mode as the situation is under control." The owners of the culled birds would be provided with coupons at the time of culling and they would be compensated accordingly.
"They will get the same rate as was given to them in 2009", the minister said adding they would try to provide them with a higher rate. Over 50,000 birds, including 20,000 ducks and pigeons, were affected with Bird Flu in the block, the sources said. :tiphat:http://www.tribuneindia.com/2011/20110921/nation.htm#8

Re: Highly pathogenic avian influenza, India (OIE, September 19 2011): One New H5N1 Poultry Outbreak, West Bengal

Character of bird flu strain yet to be studied
Aditi Tandon/TNS

New Delhi, September 22
Even as the Prime Minister?s Office expressed concern over the latest outbreak of bird flu in West Bengal and sought utmost caution, the Health Ministry today deputed a Central team to monitor its consequences on human health. Avian influenza, or bird flu, is caused by Influenza A virus that has many sub-types.

The most virulent of these are highly pathogenic avian influenza viruses that take little time to reach epidemic levels among birds. Of these sub-types, H5 (detected in Bengal), and more particularly subtype H5N1, pose the greatest concern for human health with the WHO repeatedly referring to evidence that H5N1 strain has a unique capacity to jump the species barrier and cause severe disease with high mortality in humans.

Meanwhile, India is yet to determine the exact strain of the flu that broke out in West Bengal, with Chief of the Indian Council for Medical Research Dr VM Katoch admitting to The Tribune that ?we have not yet seen the character of the strain. We are getting constant reports and our branches in the state are supporting animal husbandry staff culling chickens and destroying eggs to prevent the spread of the flu. We will gain knowledge of the nature of this strain soon?.

Asked how vigilant the people needed to be, Katoch said there was no cause for alarm or fear but added, ?It would have to be seen if the new flu strain has the capability of mutating in a way that affects humans.?

..Is mentioned in this report and it is not known whether it is the new Vietnam/China strain we have recently heard about. Villagers freely mingle with the dead birds. A scary report to say the least! :tiphat: http://www.youtube.com/watch?v=ABWv77HzRSQ&feature=player_embedded#!

30 000 birds culled in Nadia: DM [district magistrate]
------------------------------------------------------
About 30 000 birds have been culled till today [23 Sep 2011] at
Tehatta 1 block in Nadia district where there has been an outbreak of
bird flu. ["While about 14000 birds were culled on Tue 20 Sep 2011,
about 6000 birds were culled Wed 21 Sep 2011, and about 10 000 on Thu
22 Sep 2011]," Nadia district magistrate Avinaba Chanda said.

"60 teams were deployed for culling ," he said adding about 8000 birds
would be culled [on Fri 23 Sep 2011].

The Nadia administration was providing coupons to the bird owners as
per the order of the state government through which they would get the
compensation later. But government of India has ordered to arrange for
spot compensation, official sources said.

According to the district magistrate, there are 3 check points to stop
the birds from going out of the protected area within 3 km [2 mi]
radius of the affected area.

The confirmation of the outbreak of [avian influenza] from laboratory
was received on Monday night [19 Sep 2011], the DM said after which
culling started.

[This outbreak has been reported to the OIE on 19 Sep 2011 (follow-up
report no 1, available with map at
<http://web.oie.int/wahis/public.php?page=single_report&pop=1&reportid=11026>).
It is the 2nd H5N1 outbreak in India since the immediate notification
of a new epizootic, claimed to have started on 29 Aug 2011
(ProMED-mail archive no 20110909.2747).

The 1st outbreak was located in Dhuburi, Assam, northern to
Bangladesh; the 2nd, current outbreak, is located south to Bangladesh,
namely in Nadia, West Bengal, about 840 km (522 mi) distant from the
1st outbreak (see map at
<http://web.oie.int/wahis/public.php?page=event_summary&reportid=10993>).
The likely common denominator of both outbreaks is their proximity to
Bangladesh, a country that has reported, since March 2007, 519
outbreaks of avian influenza (see map at
<http://web.oie.int/wahis/public.php?page=event_summary&reportid=5154>).

The applied "control measures" in relation to HPAI, as reported by
both countries to the OIE, are the following:
Bangladesh:
Stamping out, movement control inside the country, disinfection of
infected premises/establishment(s), vaccination prohibited.

India:
Stamping out, quarantine, movement control inside the country,
disinfection of infected premises/establishment(s), screening, no
vaccination.

We have sought OIE's explanation to the difference between
"vaccination prohibited" and "no vaccination" policies. The following
explanatory note has been kindly provided:

"Vaccination prohibited" means that the use of a vaccine to control
the outbreak(s) is prohibited under any circumstances.
Vaccination in response to the outbreak(s)
Vaccination as a measure to control the outbreak(s) (such as ring
vaccination).
Where there is no vaccination, it means that they do not apply
vaccination around the outbreak(s).

So for Bangladesh the use of vaccine is prohibited in the country
(ring and routine vaccination), while in India, the Government does
not vaccinate but the use of vaccine is not forbidden."

Upon further inquiry, the following details were kindly added:
"These definitions are used mainly for immediate notifications and
follow-up reports when dealing with emergencies.

For routine vaccination you should look at 6-monthly reports to see if
the country practices mass vaccination. In general, when vaccination
is prohibited, it is already mentioned in the 6-monthly report and
when an exceptional event occurs vaccination remains prohibited."

We are very grateful to the head of OIE's Information Department, Dr
Karim Ben Jebara, for the clarifications above.

Subscribers are thus advised that OIE's immediate notifications and
follow-up reports do not address the vaccination status of the
affected holdings in countries, which do not prohibit vaccination. To
obtain that kind of information, subscribers are advised to refer to
the 6-month or annual detailed reports.

To clear the current issue, we referred to OIE's information on
"Disease control measures" as reported in the annual reports of the 2
above countries in relation to HPAI.

The following results (annual reports 2010) were found:
1. India: notifiable disease, Qf, M, Te, GSu, Qi, S
2. Bangladesh: notifiable disease, Qf, M, Gsu, Tsu, Qi, S, Z, Vp

Key:
Qf= precautions at the border
M= monitoring
Te= screening
Gsu= general surveillance
Tsu= targetted surveillance
Qi= movement control inside the country
S= stamping out
Sp= modified stamping out
Z= zoning
Vp= vaccination prohibited.
V= routine vaccination
T= treatment
Cr= control of wildlife reservoirs
Cn= control of arthropods

Since India's policy does not mention either Vp or V, it is not clear
if vaccination is allowed to be carried out by non-governmental
entities, and if HPAI H5N1 vaccines have been certified for such
(unofficial) use; this information is herewith requested. - Mod.AS]

Re: Highly pathogenic avian influenza, India (OIE, September 19 2011): One New H5N1 Poultry Outbreak, West Bengal

Latest bird flu outbreak has usual suspect
Posted: Sat Sep 24 2011, 03:55 hrs
Kolkata:
As the culling operation is on in Tehatta I bock of Nadia district in the wake of the bird flu outbreak, the state adminstration is grappling to find the reasons behind the resurfacing of the virus, a year after the country was declared free of [H5N1] virus.



The ground zero of the latest outbreak is on the Indo-Bangladesh border and once again officials are pointing towards Bangaldesh for the ?influx? of the avian flu virus.

...


Officials pointed out that a month ago, several packets of dead chicken were found in Churni rivers that flows between the two countries and very close to the place where bird flu has been reported.

Bird flu only in Nadia: Minister
Someswar Boral, TNN | Sep 25, 2011, 04.28AM IST

...


State animal resource development minister Nure Alam Chowdhury had been on a visit to Tehatta I block to review the situation. The ARD secretary informed that the 3-km radius within which culling had to be done included a portion of Bangladesh. The Centre had taken up talks with the neighbouring country to discuss the matter. The hens and ducks were buried in Lalbazar, a secluded area near Bangladesh border. Consumption, entry and exit of chicken and eggs have been restricted within a 3-km radius of the affected zone. The wheels of vehicles moving around this area were also disinfected to check the spread of avian influenza. The bird owners were promised compensation.

...

In Nadia's Tehatta I block, culling work was hampered on Saturday after workers demonstrated before the SDO to protest lack of quality food. The matter was resolved later. A total of 42,340 birds have been culled till date," said Nadia DM Avinaba Chanda.

From August 31, 2011: http://www.thestatesman.net/index.php?option=com_content&view=article&id=381801&catid=35
FAO sounds fresh birdflu alert

31 August 2011
sun narin
KOLKATA/NEW DELHI, 31 AUG: The Food and Agriculture Organisation (FAO) says that Indo-Gangetic plain and West Bengal are to be considered at the highest risk of H5N1 and Highly Pathogenic Avian Influenza (HPAI).
This comes after FAO has warned India of a possible resurgence of H5N1 (better known as birdflu) and the recent outbreaks of the disease in many other countries in Asia. ?All chickens have to be considered susceptible. However, the poultry being raised in Indo-Gangetic plain is at higher risk as the disease is entrenched in this region. The areas with previous history of HPAI outbreaks and areas where animal movements and trading have taken place, including West Bengal, would be considered at high risk,? says Dr Wantanee Kalpravidh, FAO Regional Coordinator for Asia and the Pacific.
India notified the last outbreak of avian influenza (H5N1) in Tripura in February 2011 and nothing thereafter. In early 2008, the disease had spread to more than half of West Bengal after the H5N1 strain was first confirmed in dead chickens. At least 2.2 million birds were slaughtered to control the outbreak. The government of India has just declared itself free from Notifiable Avian Influenza since July 2011.
Dr Kalpravidh said that so far the government has not adopted the vaccination policy and the strategy being used is early detection and rapid response to any disease outbreak. Procedures for outbreak containment would be culling of diseased and exposed flocks. Improvement of biosecurity at poultry farms and market has been included in the national strategy, he added. ?The government of India is giving its best attention to improve biosecurity system of poultry farms and strengthen their systems to early detect and respond to any outbreak that might occur,? he said.
FAO chief veterinary officer Mr Juan Lubroth said in a report that the government of six Asian countries, including India, should focus on preparedness and surveillance to tackle the possible outbreak. There were signs that a mutant strain of the deadly virus, with unpredictable risks to human health, is spreading in Asia and beyond. Apart from India, FAO has rung the alarm bell for Bangladesh, China, Egypt, Indonesia and Vietnam.
The H5N1 virus has infected 565 people since it first appeared in 2003, killing 331 of them, according to WHO figures. The outbreaks have risen progressively since then, with almost 800 cases recorded in 2010-11, FAO said. The latest death occurred in Cambodia earlier in the month, killing two children. Cambodia has had 16 deaths from 18 confirmed cases of bird flu since 2005. They include seven children, according to Cambodian Health Ministry official.
Mr Madan Mohan Maity, general secretary, West Bengal Poultry Federation, said that so far there is no case of H5N1 or even bird death in Bengal or any part of India. ?We hope there will be no panic over bird flu because our poultry sector is highly mechanised. The government is prepared for the disease,? he said. And in New Delhi, the government said it is fully prepared to deal with any eventuality arising out of the outbreak of avian influenza. ?A few reports have come out in the press mentioning an FAO alert against a new and deadly mutant strain of avian influenza, popularly known as Birdflu. The government has taken note of the FAO's alert and is prepared for any eventuality,? an official statement said.
