A single human case of infection by low pathogenic avian influenza
(H9N2) virus has been reported by the Institute of Epidemiology
Disease Central and Research (IEDCR), in Dhaka, Bangladesh. The
identification is dated 26 Mar 2011 and designated confirmed. The
location is given as Kamalapur, Dhaka Division. No further information
is available.

[Further information on the circumstances of this case and the extent
of the patient's illness would be welcomed.

Avian influenza A/H9N2 virus has caused repeated human infections in
Asia since 1st recorded in 1998 (see ProMED-mail archived reports
below). Human infections have generally been mild. An infection of a
5-year-old child in Hong Kong in 2003 is described in detail by Butt
et al in the Journal of Clinical Microbiology, November 2005, p.
5760-5767, Vol. 43, No. 11.

Furthermore, Matrosovichb, Kraussa and Webstera established that H9N2
influenza A viruses from poultry in Asia have human-virus-like
receptor specificity. Features of the surface glycoproteins of H9N2
viruses from Hong Kong suggested an enhanced propensity for
introduction into humans and emphasized the importance of poultry in
the zoonotic transmission of influenza viruses. (See: Virology, Volume
281, Issue 2, 15 Mar 2001, Pages 156-1620).

Re: Kamalapur, Bangladesh: Human H9N2 infection

Note that on March 16, 2011, a second H5N1 case was confirmed by the IEDCR in Kamalapur, Dhaka. See this thread: http://www.flutrackers.com/forum/sho...545#post399545

To date, this case has not been reported by WHO. Is it possible that the child had a different form of bird flu?

I was wondering the same thing. I can't find any articles on this new case. I wonder if either the second "bird flu" case was really H9N2, or alternatively if this H9N2 is an errant report of one of the H5N1 infections. Is it even standard terminology to refer to a human infection as "low pathogenic"? I thought "low pathogenic" meant that the virus caused low mortality in birds.

It does seem a bit odd that an H9N2 flu case (which has never been reported from Bangladesh in humans, and maybe not even in birds) was found in the same area as 1-2 confirmed H5N1 cases, especially considering the H5N1 cases were apparently mild.

We have here on FT at least one FAO report (http://www.flutrackers.com/forum/sho...d.php?p=387719) in which the wrong pathogen was reported in error.

IMO, something is not right with this report.

Re: FAO/Empres, One human case of H9N2 low pathogenic avian influenza infection (March 29 2011)

The WHO has confirmed the second H5N1 case (as H5N1) and explicitly mentions contact with sick poultry, removing the possibility that it was really an H9N2 case. Still no explanation of the FAO report here, though.

If this report were accurate, I suspect we would have heard more details about it by now.

Looks like the report was right after all:
