"Australia has crossed another grim threshold in its H5N1 bird flu outbreak.
For the first time, the virus has infected an Australian mainland mammal: a
long-nosed fur seal found dead at Beachport on South Australia’s Limestone
Coast, about a four-hour drive southeast of Adelaide.

This is a devastating development, although sadly not an unexpected one. H5N1
is already circulating in wild seabirds along the Limestone Coast, with many
infected greater crested terns found at Beachport itself.

This seal likely caught the virus through contact with either infected birds or
the environment they share. As of today, there is no evidence that it is part
of a wider marine mammal outbreak.

One infected seal is not a seal outbreak. But we know from overseas just how
quickly that can change."
