Anti Viral Resistance and Suspectability to swine-origin influenza A (H1N1)

[Guest guest]

From MMWR:

As of April 28, 2009, viruses from 13 (20%) of 64 patients in the

United States infected with swine-origin influenza A (H1N1) virus

(S-OIV) have

been tested for resistance to antiviral medications.

To date, all tested viruses are resistant

to amantadine and rimantadine but are susceptible to oseltamivir and

zanamivir. This report provides detailed information on the drug

susceptibility

of the newly detected S-OIVs, which will aid

in making recommendations for treatment and prophylaxis for S-OIV

infection and will contribute

to antiviral-resistance monitoring and diagnostic

test development
