Four more cases of antiviral-resistant influenza have been confirmed in Delaware by the Centers for Disease Control and Prevention (CDC).
The total number of resistant cases for the 2010-2011 season now stands at ten.
The most recent cases confirmed this month include a 45-year-old woman from Sussex County who died in February. She was the second Delawarean to die from influenza related causes this year.
A two-month-old boy, a seven-year-old girl, both from Sussex, and a 28-year-old man from New Castle County were also found to have anti-viral resistant influenza.
The Delaware Division of Public Health is investigating along with the CDC. The CDC has asked the state to increase its testing as the flu season is winding down. The CDC will use the results of that increased testing to develop updated recommendations for next year, if necessary.
