The dominant strain of annual flu in humans in January 2006 is H3N2. Measured resistance to the standard antiviral drugs amantadine and rimantadine in H3N2 in humans has increased to 91% in 2005. A combination of these two subtypes of the species known as the avian influenza virus in a country like China is a worst-case scenario.
There is no basis for assuming that an H5N1 pandemic will emerge with only the far lower 1-2% lethality rate of the Spanish flu, once assumed to be a worst-case scenario. There exists no reliable prediction of the mortality rate of an H5N1 pandemic, and it would be irresponsible to confine planning to only optimistic assumptions out of step ...
Here’s what you need to know about severe bird flu, including its symptoms and treatment, after the U.S. sees its first severe case of H5N1.

The CDC says no person-to-person spread of H5 bird flu has been detected and is using its flu surveillance systems to monitor for H5 bird flu activity in people. Since March 2024, 901 dairy herds ...
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes the disease avian influenza (often referred to as "bird flu"). It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [1]
