Health officials are investigating Delaware’s first known case of influenza that is resistant to antiviral treatment.
The Division of Public Health (DPH) identified the case in a child from Kent County on March 2. They say the child’s strain of flu was resistant to Tamiflu (oseltamivir). The child was not hospitalized and has since fully recovered. DPH officials say resistance to the antiviral treatment is very rare, and only occurred in 0.5% of cases during the 2009-2010 flu season. They do not recommend any changes to treatment of the flu.
