Since 2003 , H5N1 bird flu has infected around 950 people around the world, nearly half of whom died.

Of the 66 people infected in the US this year , the overwhelming majority have suffered only from conjunctivitis, tiredness, and a sore throat.

Researchers from the US National Institute of Allergy and Infectious Diseases took a sample of clade 2.3.2.1c the older strain from a man who died in Vietnam in 2004 .

But a sample taken from a dairy worker infected with the virus last year in Texas showed the opposite effect.

The researchers also found that the older clade kills off the cells located in the lungs quicker than the newer strain.
