EPIDEMIOLOGICAL COMMENTS
According to the Norwegian Veterinary Laboratory, the test was only weakly positive for HPAI H5, and because of the small amount of virus, the result from subtyping for neuraminidase would be uncertain. The laboratory will likely not follow up with more tests, the sample will end up as H5. Since Norway has not reported other events without a NA type, Norway considers this strain as a new strain in the country.
