This is a report on virus strains infecting humans in China. They
include Table 3 on H5N1 with number of cases and percent mortality.
Table 3 and 4 include only the H5N1 Dairy virus B3.13 infections and the
D1.1 infections are not included likely because D1.1 has the Asian H5
gene, but a North American N1 gene. They did not include the human D1.1 fatality nor the other D1.1 infections in the US and Canada. Table 3
gives the data for why the Asian H5N1 virus is claimed to have a 50% mortality. The Dairy virus (B3.13) was a reassorted virus and half the
genome came from a North American virus, and it was much less pathogenic
than the Asian H5N1. The US B3.13 data made their table likely because
the H5 and N1 genes are the same as the Asian H5N1.

There are other Avian Influenza strains currently infecting humans and
they have their own tables, and they include the recent H5N5 human
mortality in the US on Table 7.
