Bangladesh culls 13,000 chickens after bird flu outbreak

Bangladesh has culled about 13,000 chickens after fresh outbreak of bird flu in the country last month, officials said Monday.

Ataur Rahman, bird flu control room official, told Xinhua, a total of '12,789 chickens were culled so far this year after fresh outbreak of the avian influenza in commercial farms.'

Of the total, he said, '9,526 birds, including 8,821 in a commercial firm in Dhaka, were culled in the first week of this month.'

In January, when the outbreak of the disease was reported, 3,263 chickens were culled.

Habibur Rahman, director general of Bangladesh's Fisheries and Live Stock Department, said the department has strengthened its surveillance to contain further spread of the infectious disease.

So far, four districts were affected by bird flu.

Officials, however, said with the rise of temperature in March and April, the risks from the disease would gradually ease.

Bird flu was first detected in Bangladesh in a poultry farm near Dhaka in March 2007.

The disease was later spread to 47 districts between December 2007 and March 2008.

The cull went up to 117.000 chickens because they culled the whole farm which was owned by the biggest chicken & egg producer Kazi Farms.

No mention of neighboring poultry farms. I guess they're probably there but they didn't clear out a zone around the outbreak as you should do. Time will tell if that's a good idea.

[These 12 outbreaks are not only fairly substantial in number but
cover a wide geographic swath of Bangladesh from northwest to
southeast. Again, it is important to remember that in countries where
the disease still circulates, we are not done with H5N1 Avian
Influenza. For that matter, vigilant surveillance should be maintain
in areas around the world where it the disease formerly was prevalent
but no recent outbreaks have been occurring.

[This report summarizes 6 outbreaks in both commercial and backyard
poultry. Unfortunately, they are spread out across different parts of
the country. These outbreaks are due to a highly pathogenic Avian
Influenza H5N1 virus and this is the 3rd Update Report in 2011. Given
that the outbreak started in 2007, it appears as if it will be some
time before it is cleaned up completely, so we should all not forget
that H5N1 is still circulating in Southeast Asia and Egypt.

The location of these outbreaks can be seen appended to the OIE WAHID
report referenced above or at the HealthMap site

Commentary


H5N1 Confirmed In Bangladesh Toddler
Recombinomics Commentary 22:35
March 14, 2011
A 13-month-old girl was detected with bird flu virus in the capital yesterday.

The girl, however, is not having any serious breathing problem, which is normally the case.

The symptom is so mild that it has been detected because of the extensive surveillance, Mahmudur said, adding that proper treatment of the girl has been ensured.

"She is fine now and will recover soon."

The above comments describe a mild H5N1 case in Dhaka, Bangladesh. This case follows the first confirmed case in Bangladesh (also in Dhaka), who had symptoms in January, 2008, but was not reported until May, 2008.

Like this year’s case, a link to birds was not described, and treatment with an antiviral was not stated. These two cases strongly suggested that H5n1 infections in Bangladesh and India are far more widespread than the two confirmed cases in Bangladesh (and no confirmed cases in India).

Recently Israel also reported a suspect case with mild symptoms that was not lab confirmed. However, the frequent reports of human cases in Egypt strongly suggest that the lack of confirmed cases in Israel is surveillance / reporting related, which is also the case for India.

Testing for H5N1 in humans remains abysmal. Many countries with high levels of H5N1 in poultry, like Egypt or Indonesia, rarely test symptomatic cases that do not have a poultry link. Milder cases, such as the above case, would rarely seek medical attention, and most who did would rarely be tested for H5N1.

The recent receptor binding domain change (S227R) reported in H5N1 in Japan continues to increase concerns that H5N1 in humans is widespread in patients who are not tested.

The 1st case of human infection of avian influenza [A/H5N1 virus
infection] or bird flu this year [2011] has been detected in Dhaka,
confirms the Institute of Epidemiology, Disease Control and Research
(IEDCR).

IEDCR director Mahmudur Rahman told bdnews24.com that the human
infection was confirmed on Monday [14 mar 2011] after testing the
samples of saliva and nasal swab of a 13-month-old girl running a
temperature, who visited an influenza surveillance centre recently.
The surveillance centre is run jointly by the IEDCR and International
Centre for Diarrhoeal Diseases and Research, Bangladesh (ICDDR,B), he
said.

Family members of the child were also examined, said the IEDCR
director, adding that the girl, undergoing treatment in IEDCR
supervision, was out of danger. IEDCR was also examining the areas
where the child visited with her parents this year [2011], the
director said.

He informed that it was the 2nd case of avian influenza (H5N1) in
humans in the country. Bird flu was detected in a 16-month-old child
from the same area in 2008 and the health department disclosed it
September that year.

The IEDCR director, however, urged everyone not to panic. "There is
nothing to panic as the degree of infection in the girl is very low,"
he said.

Frequent bird flu outbreaks in poultry farms in different places in
the country earlier stoked fears of a serious health threat to
Bangladeshis. "The virus (H5N1) can pass on to humans from poultry any
time given the present situation. It's a public health concern," says
Dr ASM Alamgir, an influenza expert with the World Health
Organisation's Dhaka office. He says in areas currently experiencing
avian influenza outbreaks in poultry, the practice of marketing live
birds may pose a significant risk to the people involved.

"Even people should try to avoid coming into close contact with
pigeons and crows unnecessarily, as lab tests found the presence of
H5N1 in crows during the mass death in 2008 in Dhaka and Chittagong."
He suggests people consume well-cooked poultry products and maintain
bio-security in farms.

Avian flu has so far killed 306 people out of 518 infected in 15
countries and most of these cases have been linked to close contact
with infected poultry or their secretions.

Bangladesh can be a hot spot for emerging infectious and costly
diseases such as bird flu because of population growth and movement,
urbanisation, changes in food production, and other factors,
researches say. IEDCR advises doctors to take history of exposure to
sick poultry while seeing patients with serious respiratory illness,
who might have contracted the deadly strain of human avian influenza
virus.

Livestock experts say maintaining bio-security in poultry farms is the
key to stave off the avian influenza that also brings colossal damage
to the poultry industry with each strike. The world's 1st outbreak of
bird flu among humans occurred in Hong Kong in 1997, when it claimed 6
lives. That outbreak was linked to chickens and classified as H5N1.

[This is only the 2nd human case of avian influenza (H5N1) in humans
to have been recorded in Bangladesh. The previous case was a
16-month-old child from the same area in 2008. Both this infection and
the previous case involved young children and appear to have been
mild, detected during routine influenza surveillance. Confirmation by
WHO is awaited.

Bangladesh: more birds culled with avian flu
--------------------------------------------
A total of 6000 poultry birds were culled and 29 000 eggs damaged
following an outbreak of bird flu [avian A/(H5N1) influenza virus
infection] at a hatchery at Kashada village under Shivalaya upazila
[sub district] on Tuesday and Wednesday night [12-13 Apr 2011].

Some poultry birds of Pioneer Breeders Limited died in the last 3
days. The hatchery owner took samples of dead birds to the local
disease examination centre of the livestock department.

There it was detected that the fowls were attacked with bird flu,
deputy director of livestock department Hossain Mohammad said.

Shivalaya upazila nirbahi officer [chief executive of a sub-district]
Kaikobad Hossain and concerned officials were present during the
culling of the birds, he said.

[According to available information (see reference below), "In
Bangladesh, about 89 per cent of rural households have backyard
poultry, and many households keep chickens and ducks on the same
property. In the absence of fences or other barriers, backyard
chickens roam freely from one property to another. Because backyard
chickens are reared in such free range systems, they are more
vulnerable to the HPAI (H5N1) virus infection; and, if they become
infected, they can transmit the virus to domestic ducks, in which the
virus can perpetuate and infect more backyard chickens. This cycle of
virus transmission between backyard chickens and ducks would continue
until intercepted."

It seems that the cycle described has been continuing since the start
of the epizootic in February 2007, at times -- as in the current case
-- penetrating into commercial flocks. Vaccination is not allowed in
Bangladesh. So far, 480 of the outbreaks have been officially
reported; the most recent OIE follow-up report, no 31, was submitted
on 24 Mar 2011. All reports and an interactive map showing the
location of the outbreaks are available at
<http://web.oie.int/wahis/public.php?page=event_summary&reportid=5154>.

So far, 3 human cases of H5N1 have been reported from Bangladesh by
the WHO, one in 2008, 2 during 2011; no mortalities.
