Although both bird flu and MRSA have received quite a bit of media
attention, they are quite different. Bird flu is caused by an
influenza virus; MRSA (methicillin-resistant staphylococcus aureus) is
not viral, but is a bacterial pathogen that is difficult to treat
because of its resistance to penicillin antibiotics.
"Influenza A virus subtype H5N1, also known as A(H5N1) or H5N1, is a
subtype of the Influenza A virus that is capable of causing illness in
many animal species, including humans. A bird-adapted strain of H5N1,
called HPAI A(H5N1) for 'highly pathogenic avian influenza virus of
type A of subtype H5N1', is the causative agent of H5N1 flu, commonly
known as 'avian influenza' or simply 'bird flu', and is endemic in
many bird populations, especially in Southeast Asia. One strain of
HPAI A(H5N1) of Asian lineage is spreading globally. It is epizootic
(an epidemic in nonhumans) and panzootic (a disease affecting animals
of many species, especially over a wide area), killing tens of
millions of birds and spurring the culling of hundreds of millions of
other birds in an attempt to control its spread. Most references in
the media to 'bird flu' and to H5N1 are about this specific strain.
HPAI A(H5N1) is an avian disease, and there is no evidence of
efficient human-to-human transmission or of airborne transmission of
HPAI A(H5N1) to humans. In almost all cases, those infected with H5N1
have had extensive physical contact with infected birds. However,
around 50% of humans known to have been infected with the current
Asian strain of HPAI A(H5N1) have died from H5N1 flu, and H5N1 has the
potential to mutate or reassort into a strain capable of efficient
human-to-human transmission."

"Methicillin-resistant Staphylococcus aureus (MRSA) is a specific
strain of the Staphylococcus aureus bacterium that has developed
antibiotic resistance to all penicillins, including methicillin and
other narrow-spectrum ?-lactamase-resistant penicillin antibiotics.
MRSA was first discovered in the UK in 1961 and is now widespread,
particularly in the hospital setting where it is commonly termed a
superbug."
