Re: Canada - British Columbia: HP H5N2 Avian Influenza confirmed on 10 farms in Fraser Valley

I compare this with the reaction of the American press to ebola, which IMO was a non-event in USA.


This new H5N8 virus gives America a new, entirely different reservoir of influenza viruses to select
from for reassortment with human or swine viruses.
The last time that this happened was in the ~1950s and two pandemics followed
that picked new avian segments (2,4,6) in 1957 and (2,4) in 1968 for reassortment
with circulating human viruses.
While diversity in segments 4,6 is already big in the wild bird's population,
diversity in segment 2 isn't. Nor is it in 1,3,5,7 and 2 types in 8.

Well, this reassortment could also (more likely) happen in Asia, they already
had the viruses and even the domestic ducks as mixing vessel.
But now we (we=mankind) get the American types of HAs and NAs that
weren't available before. Plus the 17g types, and the American H5N2 poultry viruses.

H5N8 currently doesn't infect humans, at least we have seen no cases so far.
But we know, how quickly that can change, when it keeps reassorting.
Fouchier,Kawaoka, etc. may soon show how few mutations are needed
or what other reassortments may achieve likely transmission in humans.

H2N2/1957 and H3N2/1968 happened in Asia, but some of the segments are
closer to American avian viruses:

Re: Canada - British Columbia: HP H5N2 Avian Influenza confirmed on 10 farms in Fraser Valley

Virus Sequencing

December 17, 2014

Scientists at the Canadian Food Inspection Agency's (CFIA) National Centre for Foreign Animal Disease (NCFAD) have confirmed that the virus detected in <abbr title="British Columbia">BC</abbr> poultry is highly pathogenic avian influenza H5N2. This virus contains gene segments from the highly pathogenic Eurasian H5N8 virus, including the H5 gene, and segments from typical North American viruses, including the N2 gene.

This is the first time a Eurasian lineage highly pathogenic H5 virus has caused an outbreak of avian influenza in poultry in North America.

The appearance of this particular reassortant virus is significant due to its ability to cause high mortality in domestic poultry. The <abbr title="Canadian Food Inspection Agency">CFIA</abbr> continues to take swift action in response to this virus.

While there are no reports of H5N2 related illness in humans, as a precautionary measure public health officials are monitoring workers who are exposed to affected poultry.

Wild bird testing conducted to date has not yet detected this strain in Canada. Further studies to evaluate the risk to wild birds are being undertaken.

Poultry farmers are encouraged to protect their flocks by employing strict biosecurity measures on farm, and immediately reporting suspicious symptoms to the <abbr title="Canadian Food Inspection Agency">CFIA</abbr>.

B.C.?s poultry industry bracing for a long recovery after bird flu outbreak: expert

BY GEORDON OMAND, THE CANADIAN PRESS FEBRUARY 3, 2015 9:09 AM

VANCOUVER ? It could be as late as June before British Columbia farms are declared free of the avian flu, but recovering from the international trade implications may take far longer, an expert says.

Robin Horel, head of the Canadian Poultry and Egg Processors Council, said a clean bill of health from the Canadian Food Inspection Agency is ?just the beginning? and that more work will be needed to resume overseas trade.

Once the 11 infected commercial facilities in B.C.?s Lower Mainland are cleaned and disinfected, Horel said the CFIA imposes a 21-day restriction before allowing birds back into barns.

Restocking is followed by a three-month surveillance period, after which a farm can be labelled free of the avian flu.

?(But) the 90-day clock hasn?t wound yet because we?re still working on some of the premises,? said Horel, adding that so far only half the farms have been fully cleaned.
