China reports bird flu outbreak in poultry in SW [southwestern] province
An outbreak of bird flu in poultry has been reported in China's
southwestern mountainous province of Guizhou, the Ministry of
Agriculture (MOA) said Monday [25 Feb 2008].
The National Bird Flu Reference Laboratory confirmed the case, which
occurred in Zheng'an County, Zunyi City on [17 Feb 2008], was caused
by the highly pathogenic H5N1 subtype of the avian influenza virus,
the MOA said.
The disease, which killed 3993 birds, was brought under effective
control after the culling of another 238 364, it added.
It is China's 4th bird flu outbreak in poultry this year , with
2 in southwestern Tibet Autonomous Region and one in northwestern
Xinjiang Uygur Autonomous Region.
A 44-year-old woman who was suspected of having bird flu died in
hospital on Monday [25 Feb 2008] in the southern province of
Guangdong, the provincial health department confirmed.
China has recorded a total of 29 human bird flu cases, of which 19
were fatal, according to the World Health Organization (WHO).
On [18 Feb 2008], the Ministry of Health confirmed that a 22-year-old
man, in the central province of Hunan, tested positive for H5N1. He
died on [16 Jan 2008].
On [20 Feb 2008], a 41-year-old man, who had tested positive for
H5N1, died in Nanning, capital of southern Guangxi Zhuang Autonomous Region.
The bird flu virus is most commonly passed from sick poultry to
humans through close contact. From 2003 to [15 Feb 2008], WHO data
indicated that 227 people had died in 361 confirmed human cases of H5N1.

[Although Guizhou province is not the member of the MBDS region, it
shares the border with 2 members of the MBDS region, Yunnan province
and the Guangxi province.
This is the 4th confirmed outbreak of avian influenza among poultry
in China in 2008. The previous 3 outbreaks occurred in southwestern
Tibet Autonomous Region (see prior PRO/MBDS postings below -- there
were 2 outbreaks) and one in northwestern Xinjiang Uygur Autonomous
Region (see general ProMED-mail posting Avian influenza (04): Israel,
Bangladesh, China (Xinjiang) 20080104.0045 available at
<http://www.promedmail.org>). It is notable that there have been
confirmed cases of human infection by H5N1 coming from provinces that
have not reported confirmed outbreaks of H5N1 among the avian
population (Guangdong, Guangxi Autonomous Republic, and Hunan -- see
prior PRO/MBDS postings below). The vaccination history of the
affected poultry in this current outbreak was not described in this
report. No human infections have been reported in the same province.
