Things I did not know #125,326...H5N1 is enzootic (=endemic in animals) in some countries...

Makes perfect sense of course, I just hadn't seen that in print in my short time looking at flu.

Helen Branswell has a piece on CTVnews about the Canadian H5N1 cases, noting that the genome will be deduced and submitted to the GISAID database.

So officially, H5N1 is considered enzootic in poultry (endemic for animals) in at least 6 countries (circulating, or epizootic, in at least 9 others):

1. Bangladesh
2. China (since 2003) 
3. Egypt
4. India
5. Indonesia
6. Vietnam
