Oregon state and federal officials confirmed Wednesday that H5N1 bird flu was found in a pig living Crook County — the first such swine infection reported in the current outbreak.

Mr Bradshaw said African swine fever "could spread very rapidly through our pig herd and have huge, huge implications".

The 2009 swine flu strain arose from the recombination of several strains over years to become more transmissible in humans.

For example, when H1N1, also known as swine flu, emerged in Mexico in the spring of 2009, tens of thousands of mild cases went undetected, causing health authorities to overestimate the severity of the disease.

The initial cause of it can be traced back to 2009 and the swine flu pandemic.
