Delaware's Division of Public Health (DPH) is following up on an antiviral-resistant influenza case identified March 2 in a child from Kent County. The child was not hospitalized and has fully recovered. This is Delaware's first known case of influenza resistant to oseltamivir (brand name Tamiflu) treatment for the 2010-2011 flu season.
The case under investigation tested positive for influenza A / H1N1 in mid-February. The specimen - part of a random sample submitted for routine anti-viral resistance testing - was reported as oseltamivir-resistant the first week of March. Oseltamivir is the preferred treatment for confirmed cases of influenza. Resistance to oseltamivir is very rare, occurring in just 0.5 percent of cases studied during the 2009-2010 flu season. There is no reason to change treatment approaches at this time.
As always, DPH recommends the following precautions for both the public and clinicians:
