It is lucky that the H1N1 "swine flu" that arose in Mexico in 2009 is treatable by (sensitive to) Tamiflu. Many strains of influenza are no longer treatable with Tamiflu. They have developed mutations that make them resistant to the drug. Notably, the H5N1 avian influenza, a likely source of a future pandemic, is largely resistant. Unfortunately, as human cases of H1N1 flu are treated with Tamiflu, it, too, will likely soon develop drug resistance. | It is lucky that the H1N1 "swine flu" that arose in Mexico in 2009 is treatable by (sensitive to) Tamiflu.
