Anti-viral resistant flu found in Delaware

A one year old child from New Castle County was diagnosed with a strain of the flu that was resistant to antiviral-medication earlier this month.  

The child is the first flu case known to be resistant to the antiviral Tamiflu for the current flu season.  The diagnosis was made March 19.  The child has since recovered after being hospitalized for treatment.

“Random sampling is done routinely to determine levels of antiviral resistance,” said Dr. Karyl Rattay, Director of the Delaware Division of Public Health.  “Of 21 Delaware samples tested for resistance from November 23, 2011 to March 12, 2012, only this case has been found to be antiviral resistant.”  

Health officials say resistance to antiviral medication is rare and just one half of one percent of cases sampled by the Centers of Disease Control this year have been found to be antiviral resistant.
