Delaware’s Division of Public Health (DPH) identified an antiviral-resistant influenza case on March 19 in a 1-year-old child from New Castle County. The child was hospitalized and has fully recovered. This is Delaware’s first known case of influenza resistant to oseltamivir (brand name Tamiflu) for the current flu season. The case, which is still under investigation, tested positive for influenza A/H1N1 in mid-February. The specimen was part of a random sample submitted for routine anti-viral resistance testing. “Random sampling is done routinely to determine levels of antiviral resistance,” said Dr. Karyl Rattay, Director of the Delaware Division of Public Health (DPH). “Of 21 Delaware samples tested for resistance from November 23, 2011, to March 12, 2012, only this one case has been found to be anti-viral resistant.” The antibiotic Oseltamivir is the preferred treatment for confirmed cases of influenza. Resistance to oseltamivir is very rare and only 0.5 percent of samples tested by the Centers of Disease Control and Prevention (CDC) this season have been found to be oseltamivir-resistant. There is no reason for medical providers to change treatment approaches at this time.
