- Hello Jeff - This is a similar scenario to April-June
2005 when migratory birds were infected with H5N1 in Qinghai Lake.
-
- "The current co-circulation in China of both type
A influenza viruses, namely the highly pathogenic H5N1 and the novel, human-adapted
A (H1N1), is a matter of concern, particularly in view of China's huge
pig ("mixing vessel") population (see [1] in ProMED-mail archive
20090509.1733)."
-
- I cannot help but think that the second shoe is going
to be dropping this Winter. I hope the human Swine Flu virus will not return
in the Fall or if it does, I pray that it will not be a mutated, far more
deadly form of the A-H1N1 virus.
-
- Just as the Swine Flu AH1N1 adapted to infect humans
after circulating in pigs for some time, so, too, the Avian Flu A H5N1
can adapt to humans on its own time table.

- Outbreak of avian influenza among birds in Mongolia's
Arkhangai Aimag

-
- Mongolia's Emergency Situations Agency announced today
[25 May 2009] that, on 22 May, swans had died of unknown cause in Ogii
Nuur Lake, in the Arkhangai Aimag [see commentary]. After analysis, the
Mongolian National Livestock Infectious Disease Prevention and Control
Center announced on [24 May 2009] that the swans died due to infection
by H5N1 avian influenza. On 24 May [2009], the governor of Arkhangai Aimag
ordered closure of the outbreak area.

- The HealthMap/ProMED-mail interactive map of Mongolia
is available at http://healthmap.org/r/00di. Arkhangai ("Northern
Khangai") is one of the 21 aimags (provinces) of Mongolia. It is located
slightly west to the country's center, on the northern slopes of the Khangai
Mountains (see map at ag, in the sum (district) of the same name (see map

- The reported outbreak of HPAI H5N1 in wild swans in Mongolia
follows China's notification of 17 May 2009 of an outbreak in "wild
migratory" birds (no species identification available), reportedly
detected in Qinghai on 8 May 2009 (see ProMED-mail archive no. 20090518.1869].
Remarkably, a rather similar scenario was seen in these territories in
2005 [see ProMED-mail archive no. 20070828.2815].
-
- During late April-June 2005, an outbreak of HPAI H5N1
infection occurred among wild birds at Qinghai Lake in China. First identified
in bar headed geese (_Anser indicus_), the disease soon spread to other
avian species populating the lake. At the beginning of August 2005, the
Mongolian authorities reported an outbreak in wild birds in Erhel lake,
Alag-Ederne county, Huvsgel province, affecting wild ducks, geese and swans.
According to a 2007 Chinese paper (ref 1), sequence analysis of 15 viruses
from 6 avian species and collected at different times during the 2005 outbreak
revealed 4 different H5N1 genotypes. Importantly, H5N1 viruses isolated
in Mongolia, Russia, and Inner Mongolia were genetically closely related
to one of the genotypes isolated during the Qinghai outbreak. As noted
by the authors, this genotype virus also spread to some countries in Europe
and Africa, suggesting its dominant nature.
-
- The distance between Qinghai (China) and Arkhangai (Mongolia)
exceeds 1500 km (932 mi).
-
- The current co-circulation in China of both type A influenza
viruses, namely the highly pathogenic H5N1 and the novel, human-adapted
A (H1N1), is a matter of concern, particularly in view of China's huge
pig ("mixing vessel") population (see [1] in ProMED-mail archive
20090509.1733).
